Docker Compose with Cloud Build: running Cypress tests in CI

[akauppi]

75 prepares for a workflow using Docker Compose.

The idea is that this can be used also in CI, to run Cypress tests. However...

• gcr.io/cloud-builders/docker is v. 19.03.8 at the moment (Aug '21) and doesn't carry either docker compose or docker-compose

• docker/compose carries docker-compose 1.26.2 but gives this:

  # docker-compose up
  Unsupported config option for services.cypress: 'profiles'
  Unsupported config option for services.init: 'profiles'

  • If updated with docker compose v.2.0.0-beta.6 based on these instructions:

    # docker compose run cypress
    WARN[0000] The CYPRESS_VERSION variable is not set. Defaulting to a blank string.
    Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Keep Cypress tests disabled for now. Once Docker Compose v2 is out of beta, let's revisit the situation.

Note: Though we get the "Cannot connect to the Docker..." locally, it doesn't mean it wouldn't work in Cloud Build.

• Set up a local Dockerfile that builds the 2.0.0-beta.6 (or later)
• Try it with gcloud builds submit

No need to wait for DC 2.0. DC 1.29.something works just fine, for CI.

Current status (next branch):

Step #3: Creating app_cypress_run ... done
Step #3: wait-for-it: waiting 60 seconds for vite:3000
Step #3: wait-for-it: timeout occurred after waiting 60 seconds for vite:3000
Step #3: 124
Finished Step #3

Normal debugging. One more.. ? :hard:

Done, pushed to next.2.

CI is now able to run Cypress tests, using the official cypress/included image.

Actually (ehem), now it really is.
