Terminate docker compose when test container finishes

Question

I am currently running a docker-compose stack for basic integration tests with a protractor test runner, a nodejs server serving a web page and a wildfly server serving a java b

Answer 1

Compose has added the --exit-code-from {container} flag to docker-compose up which makes this easier.

docker-compose up --exit-code-from test-runner

Original Answer

Similar to this rspec q/a, you need to run the tests as a standalone task that report an exit status back to your CI.

You could separate the test-runner into it's own yaml or modify the test-runner to default to a no op command/entrypoint.

Separate the test runner

Specify the test-runner config separately (You might need to upgrade to version 2 networks instead of using links to work across multiple compose files).

docker-compose up -d
docker-compose -f test-runner.yml run test-runner
rc=$?
docker-compose down
exit $rc

No op test runner

Default the test-runner to a no op entrypoint/command and then manually run the test command

services:
  test-runner:
    image: "${RUNNER_IMG}"
    command: 'true'

Then

docker-compose up -d
docker-compose run test-runner /launch-tests.sh
rc=$?
docker-compose down
exit $rc

Return codes

If your CI has the concept of "post tasks" you might be able to skip the rc capturing and just run the docker-compose down after the test-runner CI task has completed. It's also possible your CI cleans up the containers for you.
