Docker Images for Gecko
This folder contains various docker images used in taskcluster as well as other misc docker images which may be useful for hacking on gecko.
Building images
Generally images can pull from the registry rather then build locally but for developing new images its often helpful to hack on them locally.
# Example: ./build.sh base
./build.sh <FOLDER>
This is a tiny wrapper around building the docker images via docker build -t $REGISTRY/$FOLDER:$FOLDER_VERSION
Adding a new image
The docker image primitives are very basic building block for constructing an "image" but generally don't help much with tagging it for deployment so we have a wrapper (./build.sh) which adds some sugar to help with tagging/versioning... Each folder should look something like this:
- your_amazing_image/
- your_amazing_image/Dockerfile: Standard docker file syntax
- your_amazing_image/VERSION: The version of the docker file (required* used during tagging)
- your_amazing_image/REGISTRY: Override default registry (useful for secret registries)
Conventions
In some image folders you will see .env files these can be used in
conjunction with the --env-file flag in docker to provide a
environment with the given environment variables. These are primarily
for convenience when manually hacking on the images.
