|
||||
<p>By default, any webapp that you deploy gets a Captain domain assigned to it in this format: <code>appname.root.domain.com</code>. However, you have the option to add as many domains as you want to this app. For example, you can add <code>www.myawesomeapp.com</code> and <code>myawesomeapp.com</code>.</p>

|
||||
<p>One of the most basic configuration that you can set for your app is environmental variables. These variables are usually used to pass in data that does not live in the code. Examples, include API key for a 3rd party service, database connection URI and etc.</p>

|
||||
<p>When you want to create an app you have the option of creating the app with "Persistent Data" or not.</p>
|
||||
<h3><a class="anchor" aria-hidden="true" id="persistent-apps"></a><a href="#persistent-apps" aria-hidden="true" class="hash-link"><svg class="hash-link-icon" aria-hidden="true" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Persistent Apps:</h3>
|
||||
<p>These are the apps that have some data that need to survive restart, crash, container update and etc. Because these apps store data on disk, once they get created they get locked down on a specific server (if you have multiple servers). You can still change the constraint so that they will be moved to another machine, but if they will lose anything that might have been stored on the current host. Examples that use persistent apps include:</p>
|
||||
<ul>
|
||||
<li>Any database that stores data on disk has to have persistent data enabled. Otherwise all data will be lost when the container restarts (due to crash, host restart and etc...)</li>
|
||||
<li>A photo upload app which does not use third party storages like Amazon S3 to store images. Instead, it locally stores uploaded images.</li>
|
||||
<li>A webapp that needs to store some user uploaded files and plugins locally on disk (like WordPress)</li>
|
||||
</ul>
|
||||
<p>The main limitation of apps with Persistent Data is that they cannot be run as multiple instances. That's because they would access the same storage area and the data can be corrupted if multiple apps try to write on the same path.</p>
|
||||
<p>Note that NOT ALL DIRECTORIES will be treated as persistent directories. After you created the app as an app with persistent data, you'll have to define directories that you want to be persistent in the app details page on web dashboard. You can let CaptainDuckDuck manage the stored directories for you, in that case, they will be placed in <code>/var/lib/docker/volumes/YOUR_VOLUME_NAME/_data</code>. Alternatively, you can set specific path on your host machine to be mapped to a directory in your container. For example, you can map <code>/var/usr</code> on your server to <code>/my-host-usr-something</code> in your container. This way you can save a file in your container at <code>/my-host-usr-something/myfile.txt</code> and the file will be available on your server at <code>/var/usr/myfile.txt</code>. If you choose to use this option (specifying a specific host path), you'll have to make sure that the path already exists in your host before assigning it.</p>

|
||||
<p>Persistent directories need to be manually removed after you remove an app from Captain dashboard. This is to avoid accidential delete of important data. To delete persisten directories, depending on the type of persistent directories, steps are different:</p>
|
||||
<ul>
|
||||
<li>Volumes (persistent directories mapped to a label):
|
||||
<img src="http://i67.tinypic.com/2w7o0o0.png" alt="Volumes">
|
||||
For this type, you need to run <code>docker volume ls</code> to see the names of the volumes, and then run <code>docker volume rm NAME_OF_VOLUME</code> to remove the volume</li>
|
||||
<li>Mapped directories on host: these are directories from your server that are mapped to a directory in your container (app). To remove them, simply remove the directory from your server via <code>rm -rf /path/to/directory</code>
|
||||
<img src="http://i63.tinypic.com/2h4e07s.png" alt="mapped"></li>
|
||||
</ul>

|
||||
<p>Generally speaking, anything that does not directly stores data on disk can be made non-persistent. You should always prefer to have non-persistent apps as they are much more flexible. Let's say you have multiple servers, if a server becomes unhealthly, all "non-persistent" apps on that server will automatically get moved to other servers whereas persistent apps are locked down to that server due to some data that they saved on that server.</p>
|
||||
<p>Also, multiple instances of non-persistent apps can be running at the same time without causing any issues as they live in isolated environment and each of them has their very own disk space. Note that non persistent apps can still write data on disk, things on temporary cache and etc, but that data will get deleted once the container restarts due to a crash, deploy, configuration update or host restart. Examples include:</p>
|
||||
<ul>
|
||||
<li>A image processor which takes a photo and runs some logic to figure out what is in the picture. This is a good example of an app that can benefit from getting spawned as multiple instances as it's CPU heavy.</li>
|
||||
<li>A TODO web app. Note that this app will definitely uses some sort of database which is persistent. But the webapp itself does not store anything directly on disk.</li>
|
||||
<li>An image upload app that uses Amazon S3 as the storage engine rather than storing images locally on disk</li>
|
||||
</ul>

||||

|
||||
<p>CaptainDuckDuck allows you to map ports from a container to the host. You should use this feature if you want a specific port of your apps/containers to be publicly accessible. The most common use case is when you want to connect to a database container from your local machine. Note that even if you don't set any port mapping, all ports are accessible from other containers on the same Captain cluster. Therefore, you should only use this option if you want the port to be publicly accessible. Make sure to have the port open, see <a href="/docs/firewall.html">firewall settings</a>.</p>
|
||||
<p>Note that you only need port mapping if your database is being accessed from an external machine. For example, if you want your NodeJS app to access your MongoDB database, and you do not need to access your MongoDB from your laptop, you don't need Port Mapping. Instead, you can use the fully qualified name for the MongoDB instance which is <code>srv-captain--mongodb-app-name</code> (replace <code>mongodb-app-name</code> with the app name you used).</p>

|
||||
<p>Your Pizza app is doing great and you are getting thousands of hits on your website. Having one instance of your app is not good enough. Your latency has gone up. Next thing you want is to consider to run multiple instances of your app on your Captain. You can do this from the Apps section of Captain web. Let's say you change your instance count to 3. Captain creates 3 instances of your app running at the same time. If any of them dies (crashes), it automatically spins off a new one! You always have 3 instances of your Pizza app running! The best part? Captain automatically spreads the requests between different instances of your app.</p>

|
||||
<p>Wow! Your Pizza app is really popular! You have 3 instances of your app running on the same server, RAM and CPU are almost maxed out. You need to get a second server. How do you connect the servers? Captain does that for you ;-) You simply get a server with Docker installed on it, similar to what you did for the original Captain server.</p>
|
||||
<p>At this point, you have to enter the following information:</p>
|
||||
<ul>
|
||||
<li>Captain IP Address (as seen by remote): this is the IP address of your first server</li>
|
||||
<li>Remote IP Address (as seen by Captain): this is the IP address of your second server</li>
|
||||
<li>Remote Username: Note that unless you have a custom setup, this should be <code>root</code></li>
|
||||
<li>Private SSH key: this is the SSH key that you use to SSH to your second server. On Linux, it's on <code>/home/yourusername/.ssh/id_rsa</code></li>
|
||||
<li>Node type: this describes what the role of the new server is. Use <code>worker</code> if you're new to Docker, for more details, read <a href="https://docs.docker.com/engine/swarm/how-swarm-mode-works/nodes/">https://docs.docker.com/engine/swarm/how-swarm-mode-works/nodes/</a></li>
|
||||
</ul>
|
||||
<p>IP address of your new server, IP address of your main Captain node, username of your remote server (root is required for Docker use), private SSH key. Now, go to the "Nodes" section of Captain, enter the values and click on Join Cluster. Done! You now have a real cluster of your own! You can now change the instance count to 6, and Captain will spin up some instances on the other server for you, also automatically load balances the request and creates new instances if one machine dies.</p>
|
||||
<p>The leader node is a manager who's been elected as Leader. This is the node where Captain and main services such as nginx and Certbot (Let's Encrypt) will be running on. All your apps automatically get distributed to nodes by docker swarm.</p>
|
||||
<p>Note: for cluster mode you will need to setup a Docker Registry.</p>

|
||||
<p>Docker Registry is simply the repository that different nodes in a cluster can access to download your app and run it. If you are not running your instance on a cluster, there is pretty much no benefit to setting up Docker Registry.</p>
|
||||
<p>On the other hand, Docker Registry is necessary for clusters. To setup Registry, simply go to your Captain web dashboard and follow the instructions. You will be given two options:</p>
|
||||
<ul>
|
||||
<li>Docker Registry managed by Captain.</li>
|
||||
<li>Docker Registry managed by a 3rd party provider.</li>
|
||||
</ul>
|
||||
<p>For most cases, a Registry managed by Captain should be good enough. Note that before switching to cluster from a single node, if you have any existing app, you will have to setup Registry and re-deploy all your existing app to make sure they are pushed to the registry and are available to all nodes, not just the main leader node.</p>

|
||||
<p>Assume we want to create a webapp that shows a list of photos with a line describing whether the image is a hotdog or not hotdog, something like this:</p>
|
||||
<ul>
|
||||
<li><IMAGE> Tags: Hotdog, Upload date: 2017-11-12</li>
|
||||
<li><ANOTHER IMAGE> Tags: NOT Hotdog, Upload date: 2017-07-08</li>
|
||||
<li><ANOTHER IMAGE> Tags: Hotdog, Upload date: 2017-07-07</li>
|
||||
<li>....</li>
|
||||
</ul>
|
||||
<p>Anyone can upload images and our very smart Artificial Intelligence tags that image with HOTDOG or NOT-HOTDOG, then we save that image on the server and we also save upload date and tags in the database.</p>

<p>To make this app, let's assume we decided to have the following components:</p>
|
||||
<ul>
|
||||
<li>NodeJS WebApp: (including static assets, frontend app, and API)</li>
|
||||
<li>PHP Image Upload app - where we can make a POST request to save a photo on disk</li>
|
||||
<li>MongoDB where we can store upload information (tags, upload date and etc)</li>
|
||||
<li>PYTHON An Image Recognition service where we can make a POST request to know whether the image is a HOTDOG or NOT HOTDOG</li>

|
||||
<p>CaptainDuckDuck allows you to indicate whether your app/database/service has persistence data or not. Apps with persistence can have "persistent directories". These directories will be preserved if your app crashes and Captain starts a new instance of that app. All other directories will get wiped and reset to their default state if the application crashes and Captain starts a new instance of the app. In our example:</p>
|
||||
<ul>
|
||||
<li>WebApp: DOES NOT have/need any persistence.</li>
|
||||
<li>Image Upload App: Needs a persistent directory where images get saved on disk (for example, <code>/uploaded_files</code>)</li>
|
||||
<li>MongoDB. Of course, this needs persistency (where we store information), we don't want to lose the database, just because our MongoDB crashed or our server got restarted.</li>
|
||||
<li>PYTHON Image Recognition app. This one does not need to save any data on disk. It simply receives an image, does some image processing and let the client know whether the image was HOTDOG or NOT HOTDOG</li>
|
||||
</ul>

|
||||
<ul>
|
||||
<li>NodeJS Web app: after you write this app, you simply create a webapp and name it <code>my-webapp</code> on Captain, you DO NOT check the persistency checkbox and you deploy your app.</li>
|
||||
<li>Image Upload app: similar to webapp described above, but we'll check the persistence checkbox when creating the app. Name this app <code>image-uploader</code>. After that, we go to app details page and add a persistent directory, the path of the directory is where your app stores images. This depends on your app, in our example, let's assume it is <code>/uploaded_files</code></li>
|
||||
<li>MongoDB: we'll use the one-click app installer to create an instance of MongoDB. We'll name this container <code>my-mongodb</code>. When the container (database) is created, you can go to the details page and you'll see that Captain automatically assigned some persistent directories to this container. This is where MongoDB saves its data.</li>
|
||||
<li>Python Image Recognition app: Again, create a new app on Captain. We do not need to set persistence for this app as it does not save any information on the disk. Let's name this app <code>image-processor</code>.</li>

</ul>

|
||||
<p>In order for your web-app to work. It needs to be able to talk to MongoDB instance, image uploader, and image processor. You can simply add a <code>srv-captain--</code> prefix to the name of the container if you want to access it from another container. For example in order to connect to your MongoDB instance which we name <code>my-mongodb</code>, you can add the following line to your NodeJS application (using mongoose library)</p>

<p>This is the same for other services; if you want to upload an image to your image uploader service you can just access it via <code>http://srv-captain--imageuploader</code></p>

<p>Simply run <code>captainduckduck deploy</code> in your git repo and follow the steps. This is the best method as it's the only method that reports potential build failures to you. Read more about it here:

<p>This method is perhaps the most convinient one. This method automatically triggers a build when you push your repo to a specific branch (like <code>master</code> or <code>staging</code> or etc). To setup this, go to your apps settings and enter the repo information:</p>
|
||||
<ul>
|
||||
<li>github/bitbucket username(email address): This is username that will be used when Captain downloads the repo.</li>
|
||||
<li>github/bitbucket password: You can enter any non-empty text, like <code>123456</code>, for public projects.</li>
|
||||
<li>repo: This is the main HTTPS address of repo, in case of github, it is in <code>github.com/someone/something</code> format.</li>
|
||||
<li>branch: The branch you want to be tracked, for example <code>master</code> or <code>production</code>...</li>
|
||||
</ul>
|
||||
<p>After you enter this information, save your configuration. And go to your apps page again. Now, you'll see a new field call webhook. Simply copy this webhook to your github/bitbucket repo. Captain listens to <code>POST</code> requests on this link and triggers a build.</p>
|
||||
<p>On Github, webhooks can be added here:</p>
|
||||
<ul>
|
||||
<li>Project > Settings > Add Webhook > URL: Captain Webhook from your apps page, Content Type: <code>application/json</code>,
|
||||
Secret: <Leave empty>, Just the <code>push</code> event.</li>
|
||||
</ul>
|
||||
<p>On Bitbucket, webhooks can be added here:</p>
|
||||
<ul>
|
||||
<li>Project > Settings > Webhooks > Add Webhook > Title: Captain Server, URL: Captain Webhook from your apps page.</li>
|
||||
</ul>

|

<p>Saving your images: images are compressed files with your built source-code that you deployed to the server. Every time you deploy a new version of your code, Docker builds a new image for the new version and keeps the old image by default. If you want to clean up all "unused" images on your server, run</p>

<p>Important Note: Use this approach only if you have a Docker registry set up (local or remote). This is due to an existing bug in Docker, see <a href="https://github.com/githubsaturn/captainduckduck/issues/180">here</a> for more details on the problem and also see the related <a href="https://github.com/moby/moby/issues/36295">Docker Issue</a></p>

|
||||
<p>Volumes, aka "Persistent Directories". When you create an app with persistent data, like a database, you will assign it a persistent directory. When you change the persistent directory, or when you delete your app, you don't need the volumes anymore. Cleaning up orphaned volumes are tricky. If you have a useful volume for an app that is "currently" crashing and not-running, that volume is considered as "orphaned" by Docker :( So, to safely clean up orphaned volumes, first, check to see if all your services are running by:</p>
|
||||
<pre><code class="hljs">docker<span class="hljs-built_in"> service </span>ls
|
||||
</code></pre>
|
||||
<p>Under REPLICAS, you should see <code>1/1</code>, <code>2/2</code> and etc. If you see a service that is not running, then do not proceed! Otherwise, go head and clean-up orphaned volumes by:</p>
|
||||
<pre><code class="hljs">docker <span class="hljs-keyword">volume</span><span class="bash"> prune
|
||||
</span></code></pre>
|
||||
<p>Alternatively, you can first list all volumes, and delete only the ones that you don't want:</p>
|
||||
<pre><code class="hljs">docker <span class="hljs-keyword">volume</span><span class="bash"> ls <span class="hljs-comment"># lists all volumes</span>
|
||||
</span>docker <span class="hljs-keyword">volume</span><span class="bash"> rm volume-name-goes-here <span class="hljs-comment"># removes a specific volume</span>

|
||||
<p>One of the benefits of Captain, is the ONE CLICK HTTPS activation. Simply click on Enable HTTPs on your dashboard and after a couple of seconds your HTTPS is enabled. Note that once HTTPS is enabled, you cannot change your root domain, i.e. <code>something.mydomain.com</code>, of course it's always possible to re-install Captain and change it. After enabling HTTPS, you can optionally, although very recommended, enforce HTTPS for all requests, i.e. denying plain insecure HTTP connections and redirect them to HTTPS. Make sure you manually check HTTPS before doing this. Simply go to <code>https://captain.something.mydomain.com</code> and if it works, you can safely force HTTPS.</p>

|
||||
<p>You have full control over enabling HTTPS on your own apps. Once Captain root HTTPS is enabled, you can enable HTTPS for individual apps. To do so, simply go to Captain web, select Apps from the left side menu, scroll to your desired app, and click on Enable HTTPS. That's it!</p>

<ul>
|

<li>80 TCP for regular HTTP connections</li>
|

<li>443 TCP for secure HTTPS connections</li>
|

</ul>
|

<p>Or simply disable firewall entirely. In case of an ubuntu server, run <code>ufw disable</code>.</p>
|
||||
<p>Also, if you are using Port Mapping to allow external connections, for example from your laptop to a MySQL instance on Captain, you will have to add the corresponding port to the exclusion as well.</p>

|
||||
<p>During installation, you'll be asked to point a wildcard DNS entry to your Captain IP Address. If you need help with domain name, see <a href="#setup-domain-and-dns">Domain and DNS</a>. This will cost you as low as $2 a year.</p>
|

|
||||
<p>Captain has to be installed on a machine with a public IP address. If you need help with Public IP, see <a href="/docs/server-purchase.html">Server & Public IP address</a>. This will cost you as low as $5 a month. If you use the DigitalOcean referral code, you'll get $10 credit - two months worth of free server: <a href="https://m.do.co/c/6410aa23d3f3">https://m.do.co/c/6410aa23d3f3</a></p>
|
||||
<p><em><strong>CPU Architecture</strong>:</em> Although CaptainDuckDuck source code is compatible with any CPU architecture, the Docker build available on Docker Hub is built for x86 CPU. Therefore, If your CPU is ARM, you can download the source code and build it on your ARM architecture in order to run it.</p>
|
||||
<p><em><strong>Recommended Stack</strong>:</em> CaptainDuckDuck is tested on Ubuntu 16.04 and Docker 17.06. If you're using CaptainDuckDuck on a different OS, you might want to look at <a href="https://docs.docker.com/engine/userguide/storagedriver/selectadriver/#supported-storage-drivers-per-linux-distribution">https://docs.docker.com/engine/userguide/storagedriver/selectadriver/#supported-storage-drivers-per-linux-distribution</a>.</p>
|
||||
<p><em><strong>Minimum RAM</strong>:</em> Note that the build process sometimes consumes too much RAM, and 512MB RAM might not be enough (see <a href="https://github.com/githubsaturn/captainduckduck/issues/28">https://github.com/githubsaturn/captainduckduck/issues/28</a>). Most providers offer a minimum of 1GB RAM on $5 instance including DigitalOcean, Vultr, Scaleway, Linode, SSD Nodes and etc.</p>
|
||||
<p>You can install Captain on your laptop which is behind NAT (your router) for testing purposes, but it requires some special setup, like port forwarding.</p>

<p>If you get your server from DigitalOcean, you can select a server with "pre-installed Docker". This will be the easiest option. Otherwise, you can install Docker CE by following this instruction:

|
||||
<p>Just run the following line, sit back and enjoy!</p>
|
||||
<pre><code class="hljs css bash"> mkdir /captain && docker run -p 80:80 -p 443:443 -p 3000:3000 -v /var/run/docker.sock:/var/run/docker.sock dockersaturn/captainduckduck
|
||||
</code></pre>
|
||||
<p>You will see a bunch of outputs on your screen. Once the Captain is initialized, you can visit <code>http://[IP_OF_YOUR_SERVER]:3000</code> in your browser and login to Captain using the default password <code>captain42</code>. You can change your password later. Do not make any changes in the dashboard. We'll use the command line tool to setup the server.</p>

|
||||
<p>Let's say you own <code>mydomain.com</code>. You can set <code>*.something.mydomain.com</code> as an <code>A-record</code> in your DNS settings to point to the IP address of the server where you installed Captain. Note that it can take several hours for this change to take into effect. It will show up like this in your DNS configs:</p>
|
||||
<ul>
|
||||
<li><strong>TYPE</strong>: A record</li>
|
||||
<li><strong>HOST</strong>: <code>*.something</code></li>
|
||||
<li><strong>POINTS TO</strong>: (IP Address of your server)</li>
|
||||
<li><strong>TTL</strong>: (doesn't really matter)</li>
|
||||
</ul>
|
||||
<p>To confirm, go to <a href="https://mxtoolbox.com/DNSLookup.aspx">https://mxtoolbox.com/DNSLookup.aspx</a> and enter <code>randomthing123.something.mydomain.com</code> and check if IP address resolves to the IP you set in your DNS. Note that <code>randomthing123</code> is needed because you set a wildcard entry in your DNS by setting <code>*.something</code> as your host, not <code>something</code>.</p>

</code></pre>
|
||||
<p>Then, run</p>
|

</code></pre>
|
||||
<p>Follow the steps and login to your captain instance. When prompted to enter the root domain, enter <code>something.mydomain.com</code> assuming that you set <code>*.something.mydomain.com</code> to point to your IP address in step #2. Now you can access your captain from <code>captain.something.mydomain.com</code></p>

|
||||
<p>Go to the Captain in your browser, from the left menu select Apps and create a new app. Name it <code>my-first-app</code>. Then, download any of the test apps <a href="https://github.com/githubsaturn/captainduckduck/tree/master/captain-sample-apps">here</a>, unzip the content. and while inside the directory of the test app, run:</p>
|
||||
<pre><code class="hljs css bash">/home/Desktop/captain-examples/captain-node$ captainduckduck deploy
|
||||
</code></pre>
|
||||
<p>Follow the instructions, enter <code>my-first-app</code> when asked for app name. First time build takes about two minutes. After build is completed, visit <code>my-first-app.something.mydomain.com</code> where <code>something.mydomain.com</code> is your root domain.
|
||||
CONGRATS! Your app is live!!</p>
|
||||
<p>You can connect multiple custom domains (like <code>www.my-app.com</code>) to a single app and enable HTTPS and do much more in the app's settings page.</p>
|
||||
<p>Note that when you run <code>captainduckduck deploy</code>, the current git commit will be sent over to your server. <strong>IMPORTANT:</strong> uncommited files and files in <code>gitignore</code> WILL NOT get pushed to the server.</p>
|
||||
<p>You can visit Captain in the browser and set custom parameters for your app such as environment variables, and do much more! For more details regarding deployment, please see CLI docs. For details on <code>captain-definition</code> file, see <a href="/docs/captain-definition-file.html">Captain Definition File</a>.</p>

|
||||
<p>Although CaptainDuckDuck automatically manages everything about routing HTTP requests to your apps, there might still be some special config values that you want to manually tweak. It can be special caching logic for special file type or route, timeout customization, max body size and many more parameters that you can manually adjust via nginx.</p>
|
||||
<p>CaptianDuckDuck enables you to manually adjust these parameters via fully customized config files. There are three areas that you can adjust parameters:</p>
|
||||
<ul>
|
||||
<li>NGINX Base Config File (<code>/etc/nginx/nginx.conf</code>). This is the first file that NGINX will look at. It redirects nginx to look up other config files. You can manually tweak this file in web dashboard, settings.</li>
|
||||
<li>CaptainDuckDuck Config File (<code>/etc/nginx/conf.d/captain-root.conf</code>). This is the config file that you, the developer, will interact with when you visit <code>captain.root.domain.com</code>. Typically, you shouldn't need to modify this file. But if you need to, you can modify it in web dashboard > settings</li>
|
||||
<li>Application Specific Config File (<code>/etc/nginx/conf.d/captain.conf</code>). This is where you can change application-specific settings. Let's say, you have a video uploader app where you want to allow incoming body size to be 1GB. You can do so, by going to web dashboard > Apps > Apps Edit and manually change this parameter. Note that any change that you make is only applied to this specific app, all other apps will use the default config. This configuration template will be applied to ALL DOMAINS pointing to the app, i.e., Captain creates one server block for <code>my-app-name.captainroot.domain.com</code> and potentially another server block <code>www.myapp.com</code> and etc...</li>
|
||||
</ul>
|
||||
<p>Once you've changed the template, you can see the compiled version of your nginx configs at <code>/captain/generated/nginx</code> in order to verify whether the final compiled version is what you wanted. Note that you CANNOT MANUALLY modify these files as they will get overridden by Captain. If you want to make any change, you should always change the Nginx template in CaptainDuckDuck dashboard.</p>

|
||||
<p>On top of config customization, you might need to use some files in your nginx container, things such as custom SSL certs, specific static assets and etc. Since in CaptainDuckDuck instance, everything (including nginx) is sitting in a separate container, you'll need to map a directory from your host to the container. Captain already did that for you. The directory <code>/captain/nginx-shared</code> in your server is available in your nginx container as <code>/nginx-shared</code>. Let's say you place a custom SSL cert in that folder and call it <code>/captain/nginx-shared/custom-cert.pem</code>. In order to reference that file in your nginx config, you'll use <code>/nginx-shared/custom-cert.pem</code></p>

|
||||
<p>They all come with pre-configured settings, however, you'll be have the option to customize the settings. For example, MySQL database uses port 3306, but you can change this port to another port if it suits your needs.</p>
|
||||
<p>It is important to mention that some of these configuration parameters, might show up as environmental variables in your app settings after you deploy the app, however, their values only being used in the installing phase. i.e., changing password of MySQL through changing the PASSWORD environmental variable will not work. Instead, you should use MySQL commands to change the password. The PASSWORD environmental variable is being used to set up the original password during the installation phase.</p>

|
||||
<p>Note that since all these applications are Docker containers, you can have multiple MySQL databases on running on port 3306 without having any conflict.</p>
|
||||
<p>However, if you want to connect to your database from a remote machine (e.g. your laptop) you need to map a container port to a server port. In that case, you have to map two different ports on the server, for example:</p>
|
||||
<ul>
|
||||
<li>Port 1001 of the server goes to mysql-1 port 3306</li>
|
||||
<li>Port 1002 of the server goes to mysql-2 port 3306</li>
|
||||
</ul>
|
||||
<p>Port mapping is needed if you want to connect to a database from a remote machine. You can read more about it <a href="/docs/app-configuration.html#port-mapping">Captain Configuration - Port Mapping</a>.</p>

This is a very advanced operation and requires attention. Otherwise, it can break the deployment for your app.</p>
|
||||
<p>This script will run right before your container (i.e. app) gets updated due to a configuration change or app deploy. In this script, you can modify the Docker service object, invoke an HTTP call, and literally do anything. The template for this script is:</p>
|
||||
<pre><code class="hljs"><span class="hljs-keyword">var</span> preDeployFunction = <span class="hljs-function"><span class="hljs-keyword">function</span> (<span class="hljs-params">captainAppObj, dockerUpdateObject</span>) </span>{
|
||||
<span class="hljs-keyword">return</span> <span class="hljs-built_in">Promise</span>.resolve()
|
||||
.then(<span class="hljs-function"><span class="hljs-keyword">function</span>(<span class="hljs-params"></span>)</span>{
|
||||
|
||||
<span class="hljs-comment">// Do something in a Promise form</span>
|
||||
|
||||
<span class="hljs-comment">// In the end, return the "possibly-modified" dockerUpdateObject</span>
|
||||
<span class="hljs-keyword">return</span> dockerUpdateObject;
|
||||
});
|
||||
};
|
||||
|
||||
</code></pre>
|
||||
<p>Note that <code>captainAppObj</code>, is the app object as saved in <code>/captain/config.conf</code> file, and <code>dockerUpdateObject</code> is the service update object that is being passed to Docker to update the service (environmental vars, image version and etc). This object is as per <a href="https://docs.docker.com/engine/api/v1.30/#operation/ServiceUpdate">Docker docs</a>.</p>
|
||||
<p>Since this script will be executed in CaptainDuckDuck process, you'll get access to all node dependecies that CaptainDuckDuck has, see <a href="https://github.com/githubsaturn/captainduckduck/blob/master/app-backend/package.json">CaptainDuckDuck/app-backend/package.json</a>. For example, the following script injects a UUID mapped to the deployed version to service label with every update:</p>
|
||||
<pre><code class="hljs"><span class="hljs-keyword">var</span> uuid = <span class="hljs-built_in">require</span>(<span class="hljs-string">'uuid/v4'</span>);
|
||||
|
||||
<span class="hljs-keyword">var</span> preDeployFunction = <span class="hljs-function"><span class="hljs-keyword">function</span> (<span class="hljs-params">captainAppObj, dockerUpdateObject</span>) </span>{
|
||||
<span class="hljs-keyword">return</span> <span class="hljs-built_in">Promise</span>.resolve()
|
||||
.then(<span class="hljs-function"><span class="hljs-keyword">function</span>(<span class="hljs-params"></span>)</span>{
|
||||
|
||||
dockerUpdateObject.TaskTemplate.ContainerSpec.Labels[uuid()] =
|
||||
captainAppObj.deployedVersion+ <span class="hljs-string">''</span>;
|
||||
<span class="hljs-keyword">return</span> dockerUpdateObject;
|
||||
});
|
||||
};
|
||||
|
||||
</code></pre>
|
||||
<p>Note that this pre-deploy script, particularly Docker service update object, is complicated. Hence, it is strongly recommended to use this pre-deploy method if you are an expert user. For example, note that how an empty string is being added to the deployed version in this line:</p>
|
||||
<pre><code class="hljs">dockerUpdateObject.<span class="hljs-symbol">TaskTemplate</span>.<span class="hljs-symbol">ContainerSpec</span>.<span class="hljs-symbol">Labels</span>[uuid()] = captainAppObj.deployedVersion+ <span class="hljs-string">''</span>;
|
||||
</code></pre>
|
||||
<p>Removing this causes an error. To see logs, you need to run <code>docker service logs captain-captain --follow</code>. Even the error from Docker is not very clear. All in all, this is an advanced feature and is not recommended for beginners and intermiate users.</p>

<p>You always want to see how your app is behaving. Is it eating up your memory or CPU? Or is your network connection slow? You can answer all these questions by visiting Captain Monitoring menu from the web dashboard. You can enable <a href="https://github.com/firehol/netdata">NetData</a> which is a server monitoring tool and monitor your server.</p>

Note that this is an advanced process. Some of the concepts used in this section are not easy for the beginners. In order to run CaptainDuckDuck on your local machine (just for testing and development) you need:</p>
|
||||
<ul>
|
||||
<li>Docker installed on your machine.</li>
|
||||
<li>A local DNS server on your machine. You need to point <code>*.captain.x</code> to <code>127.0.0.1</code> or <code>192.168.1.2</code> (your local ip). <strong>NOTE</strong> that <code>etc/hosts</code> won't be enough as Captain needs a wildcard entry and <code>etc/hosts</code> does not allow wildcards, i.e. <code>*.something</code>.
|
||||
<ul>
|
||||
<li>On ubuntu 16, <code>dnsmasq</code> (a local DNS server) is built-in. So, it's as simple of editing this file: <code>/etc/NetworkManager/dnsmasq.d/dnsmasq-localhost.conf</code> (create if does not exist) And add this line to it: <code>address=/captain.x/192.168.1.2</code> where <code>192.168.1.2</code> is your local IP address. To make sure you have <code>dnsmasq</code>, you can run <code>which dnsmasq</code> on your terminal, if it's available, path of it will be printed on the terminal, otherwise, there won't be anything printed on your terminal</li>
|
||||
</ul></li>
|
||||
</ul>
|
||||
<p>To verify you have both prerequisites mentioned above:</p>
|
||||
<ul>
|
||||
<li>Run <code>docker version</code> and make sure your version is at least the version mentioned in the <a href="/docs/get-started.html#c-install-docker-on-server-at-least-version-1706x">docs</a></li>
|
||||
<li>Run <code>nslookup askjdfklasjflk.captain.x</code> and make sure it resolves to <code>127.0.0.1</code> or your local ip (something like <code>192.168.1.2</code>):</li>
|
||||
</ul>
|
||||
<pre><code class="hljs"><span class="hljs-selector-tag">Server</span>: 127<span class="hljs-selector-class">.0</span><span class="hljs-selector-class">.1</span><span class="hljs-selector-class">.1</span>

<span class="hljs-selector-tag">Address</span>: 192<span class="hljs-selector-class">.168</span><span class="hljs-selector-class">.1</span><span class="hljs-selector-class">.2</span>
|
||||
</code></pre>
|
||||
<p>Once you confirmed that you have the prereqs ready, you can go ahead and install Captain on your machine, similar to what you do on server. Make sure you run as a user with sufficient permission, i.e. <code>sudo</code> on linux based systems. Just follow the steps outlined here: <a href="get-started#step-1-captain-installation">Captain Installation</a></p>
|
||||
<p><strong>EXCEPT</strong>
|
||||
Do not run <code>captainduckduck serversetup</code>. Instead, go to <a href="http://localhost:3000">http://localhost:3000</a> and manually set root domain to <code>captain.x</code>. DO NOT enable/force HTTPS. Obviously, you cannot enable HTTPS on your local domain (captain.x).</p>
|
||||
<p>Once you set your root domain as <code>captain.x</code>, use <code>captainduckduck login</code> and enter <code>captain.captain.x</code> as your captain URL and captain42 as your password.</p>
|
||||
<p><strong>NON-LINUX USERS</strong>
|
||||
You need to add <code>/captain</code> to shared paths.
|
||||
To do so, click on the Docker icon -> Setting -> File Sharing and add <code>/captain</code></p>
|
||||
<p>You are set!</p>

<p>As mentioned above, running a local machine is an advanced task and might fail due to different reasons, depending on error your solution is different. For example, if you get the following error:</p>

<p>DigitalOcean calls their servers "Droplets". After signing up, go to the Droplets section and click on "Create Droplet". Under choose an image, click on One-Click Apps, and select Docker. This way, Docker comes pre-installed with your server. If you have an SSH key, enter your SSH key at the bottom of this Droplet Create page, if not, don't worry, it's just alternative password. Once your Droplet is created, you will get an email with IP address of your server, user and pass. If you know how to SSH, then great, SSH into your server. If not, again don't worry! DigitalOcean is really beginner friendly. Simply go to your Droplets section on your DigitalOcean account, click on the Droplet you created. From the menu on the left side, select ACCESS and launch console. Enter <code>root</code> when asked for login and enter the password which you received in email. If you didn't receive your password in email, click on Reset Root Password below Launch Console button. Note that you'll have to type your long password. The web interface that DigitalOcean gives you does not support Copy/Paste ctrl+c ctrl+v.</p>
|
||||
<p>At this point you are logged into your server and you can run captain installer: <code>docker run -v /var/run/docker.sock:/var/run/docker.sock dockersaturn/captainduckduck</code></p>

|
||||
<p>There is a whole set of reasons for this.</p>
|
||||
<p>First you need to make sure that CaptainDuckDuck is running on your server. To check this, ssh to your server and run <code>docker service ps captain-captain --no-trunc</code>. You might see Captain is getting restarted constantly due to an error. Fix the issue and retry. See here for example: <a href="https://github.com/githubsaturn/captainduckduck/issues/14">https://github.com/githubsaturn/captainduckduck/issues/14</a></p>
|
||||
<p>Linode for example is notorious for <a href="https://github.com/docker/machine/issues/2753#issuecomment-171822791">this kind of problem</a> and <a href="https://github.com/docker/machine/issues/2753#issuecomment-188353704">this</a></p>
|
||||
<p>If you don't see any errors when your ran <code>docker service ps captain-captain --no-trunc</code>, then try <code>curl localhost:3000 -v</code>. If successful, it's probably your firewall that's blocking the connection. See <a href="/docs/firewall.html">Firewall Docs</a>.</p>

|
||||
<p>This applies to you if:</p>
|
||||
<ul>
|
||||
<li>You have been able to setup your server and access it via <code>captain.rootdomain.example.com</code>.</li>
|
||||
<li>You have been able to deploy one of the samples apps (see <a href="https://github.com/githubsaturn/captainduckduck/tree/master/captain-sample-apps">here</a>) successfully and it worked.</li>
|
||||
<li>You tried to deploy your own application and it deployed successfully, but when you try to access it via <code>yourappname.root.example.com</code> you get a 502 error.</li>
|
||||
</ul>
|
||||
<p>If all above points are correct, this is how to troubleshoot:</p>
|
||||
<ul>
|
||||
<li>SSH to your server and view your application logs. Make sure it hasn't crashed and it's running. To view logs, please see the section at the end of this page "<a href="#how-to-view-my-applications-log">How to view my application's log</a>"</li>
|
||||
<li>If you application logs show that your application is running, the most common case is that your application is binding to a custom port, not port 80. See here for <a href="https://github.com/githubsaturn/captainduckduck/issues/130">the fix</a> .</li>

|

<p>Your application is deployed as a Docker service. For example, if your app name in captain is <code>my-app</code> you can view your logs by connecting to your server via SSH and run the following command:</p>
|

<pre><code class="hljs">docker<span class="hljs-built_in"> service </span>logs srv-captain--my-app --since 60m --follow
|
||||
</code></pre>
|
||||
<p>Note that Docker service name is prefixed with <code>srv-captain--</code>. Also, you can replace 60m with 10m to view last 10 minutes.</p>

|
||||
<p>Captain uses docker swarm to support clustering and restarting containers if they stop. That's why it keeps re-appearing. Try this:</p>
|
||||
<p><code>docker service rm $(docker service ls -q)</code></p>
|
||||
<p>then</p>
|
||||
<p><code>docker swarm leave --force</code></p>
