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).

Building and testing

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

Changing container timezone

If you need to change the timezone that the container uses, it is defined by the TZ environment variable. The default is Europe/London.

 TZ=Europe/London

You can override this by using the -e argument to docker run and specifying your timezone.

-e TZ="Australia/Melbourne"
