Docker Images

This folder defines three images used for Taskcluster CI:

1. A docker image suitable for testing things in a browser.
2. A docker image used for testing things that need a running rabbit server.
3. A docker image containing both Node and Go, for yarn generate

The images are based on the same Node and Go versions as the rest of Taskcluster. The image label is based on these versions.

To generate the docker images, install jq and run ./build-<imagename>.sh. If you are happy with the results, you have to push them to make them available for tests in taskcluster.

Browser Test

The browser-test image includes a copy of the ESR version of Firefox. Tests should not be particularly sensitive to the Firefox version.

Test the browser-test image with the following, which approximates what runs in CI:

docker run -ti --rm -v $PWD:/repo taskcluster/browser-test:10.14.0 bash -c '
    git clone /repo /build &&
    cd /build/clients/client-web &&
    yarn &&
    { Xvfb :99 -screen 0 640x480x8 -nolisten tcp & } &&
    sleep 2 &&
    CHROME_BIN=firefox DISPLAY=:99 yarn test'

Rabbit Test

This is pretty much exactly the standard node image but with rabbitmq-server installed.

Node-Go

This is a base Node image with the necessary bits of the Golang image copied in. This takes advantage of the fact that both imgaes are based on Debian "stretch".
