lancachenet/ubuntu repository overview

⁠Ubuntu Docker Image

This image provides a standard ubuntu docker base image for other docker images to build on top of.

It is currently based on 18.04 LTS (Bionic Beaver)

⁠Extending this image

You can easily extend the behavour of this image in the following ways

• /hooks/entrypoint-pre.d/ Executables placed in this directory are executed very early on, before anything else is done.

• /hooks/entrypoint-run If it exists, this is executed if the default command is not overridden. After it's execution completes the default command is executed.

• /hooks/entrypoint-exec If it exists, this is executed if default command is overridden. After it's execution completes the default command is executed.

• /hooks/supervisord-pre.d/ Executables placed in this directory are executed just before supervisord is executed.

• /hooks/supervisord-ready If it exists, this is executed once supervisord is read. This is triggered from supervisord itself, when it fires the SUPERVISOR_STATE_CHANGE_RUNNING event.

⁠Usage

This docker image is not designed for use by anyone outside of the steamcache organisation, you're welcome to try, but support will be limited: HERE BE DRAGONS

1. Make a Dockerfile and specify lancachenet/ubuntu on the FROM line.
2. Anything you want run in the container should be started by supervisord.
3. Use a directory called overlay if you need to copy files in to your new image (see Dockerfile for this image as an example).

To build just run docker build --tag lancachenet/ubuntu:testing .. To test you can run ./run_tests.sh
