Captain allows you to set custom configurations for your nginx router. This will allow high customization level in terms of caching, special routing, http2 and etc.

Note that templates are build using EJS template pattern. Do not change the areas beween <% and %> unless you really know what you're doing!

Every time you deploy a new build, Docker builds a new image for you. Typically, a large part of this image is shared between the old version and the new version, but a small chunk is added to your disk with each build. You can read more about disk cleanup in the docs, but as a simple interface, this widget gives you the ability to perform image cleanups on demand.

You can perform this action, after each deploy. But it's typically not needed with that frequency. For typical mid-sized projects, it's recommended to perform this cleanup after every ~20 builds.

With default parameter, it keeps the last two recent builds of all current apps, and creates a list of images that can be deleted (by clicking on Get List button). You can select which images you want to delete and click on Remove Images button. You might noticed that some images are not deleted even though you clicked on Remove Images, it means they are being directly or indirectly in-use by Docker. A common example For indirect usage is an image whose child image is being used by an alive container.

In future versions, this cleanup will be automatically done after each build.
