Sourcegraph derivative Docker images

This directory contains Sourcegraph docker images which are derivatives of an existing Docker image, but with better defaults for our use cases. For example:

• sourcegraph/alpine handles setting up a sourcegraph user account, installing common packages.
• sourcegraph/postgres-11.4 is postgres-11.4 but with some Sourcegraph defaults.

If you are looking for our non-derivative Docker images, see e.g. /cmd/.../Dockerfile and /enterprise/cmd/.../Dockerfile instead.

Building

All images in this directory are built and published automatically on CI:

• See the handbook for more information
• Or see how to build a test image if you need to build a test image without merging your change to master first.

Adding a new image

1. Create a build.sh and add your publishing script to it - the script should end with docker tag ... "$IMAGE". See the scripts in this directory for examples.
2. Ensure your new script is executable with chmod +x build.sh (you can try it via e.g. IMAGE=fake-repo/cadvisor:latest docker-images/$SERVICE/build.sh, or by building a test image)
3. Add an image to the automated builds pipeline by adding it to SourcegraphDockerImages.
