Local and CI Containers

[stonier]

🎉 New feature

Bazel containers for VSCode devcontainers (local) and gcr (CI).

Summary

Containers for vscode devcontainer (local) and the GCR (CI) workflows.

The important tidbit here is that the same Dockerfile is sourced for both local and CI workflows.

• Dockerfile based on focal, installs bazelisk adds user zen, also adds some minor conveniences
• A devcontainer.json that just reflects the Dockerfile to a local vscode workflow
• A containers.yml github action that pushes a container built from Dockerfile to the org's GCR

An example run of the action: https://github.com/maliput/maliput/actions/runs/6203150728

The only github configuration needed for this action is:

• Organisation -> Actions -> General -> Workflow Permissions -> Read and Write
• Repo -> Actions -> General -> Workflow Permissions -> Read and Write

Our organization and repo were already configured.

NB: I had problems fighting permissions on this. Turns out that you can't 'push' to the GCR from in a PR from a fork, even if your user is in both organization and repo with the correct priveleges.

Test it

Devcontainers

• Install vscode
• Launch vscode from the project root (or open it from inside vscode)
• Reopen in container
• Open a terminal
• Build

bazel build //...

Action

Trigger a manual run of the action at https://github.com/maliput/maliput/actions/workflows/containers.yml
