🌱 feat: Add container check CI job

[mateusoliveira43]

Why the changes were made

Check that scaffolded container commands (make docker-build, make docker-push and make docker-buildx) always work.

The job checks that by building and pushing container images to ttl.sh registry.

The job also checks that scaffolded Dockerfile follows linting rules from hadolint.

How to test the changes made

Used lint-sample.yml as base for new job.

Hi @mateusoliveira43. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

I think we should only call it if

• testdata/project-v4/Makefile
• testdata/project-v4/Dockerfile
• OR this file changes

[mateusoliveira43]

Agreed, will make change

[mateusoliveira43]

could run a matrix here to check all 3 testdata folders (project-v4, project-v4-multigroup and project-v4-with-plugins). Needed or just one is enough?

[camilamacedo86]

The task is to use docker-buildx, check the Docker images, and validate whether the image has been generated for all platforms.

However, I believe this is related to the changes proposed in this PR.

WDYT about we do that in another way?
What do you think about running the necessary commands in the PR to ensure everything is still working as expected after your changes? Additionally, you could include the results in the PR description to demonstrate that it works as intended.

[mateusoliveira43]

I can do that yes

But would not be nice to have this automated?

If not, all PR that involve container related changes would require one more step, right?
