How to target container in GitHub actions? - docker

Question

I am trying to use GitHub Actions to fire up a Postgres container for my tests. I have a script called build.sh that gets called when npm run build is called via GitHub actions. This script calls upon restore-schema.sh (shown below).
The issue here is when restore-schema.sh gets ran, I keep getting Error: no such container: postgres. GitHub actions is naming the container some arbitrary string. Is there not a way I can run docker exec on an image or somehow name the postgres container that GitHub actions is creating? I've looked through both documentations to no avail.
How should I go about this? I noticed that in the Docker run ps screenshot, it shows command docker-entrypoint.sh. Should I use this instead? Do I specify the Dockerfile inside .github/workflows/?
I tried to include as much relevant information as possible - comment if you need any other information please.

Answer 1

Try the --name option
options: >-
--health-cmd pg_isready
--health-interval 10s
--health-timeout 5s
--health-retries 5
--name postgres
https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjob_idservices
jobs.<job_id>.services.options: Additional Docker container resource options. For a list of options, see "docker create options."
Another solution I've seen is using last created container
docker exec -it $(docker ps --latest --quiet) bash
