ubuntu-latest pipelines will use ubuntu-24.04 soon. For more details, see https://github.com/actions/runner-images/issues/10636

A user should be specified in the dockerfile, otherwise the image will run as root

When installing a package, its pin version should be defined

It is considered a best practice for every executable in a container to be owned by the root user even if it is executed by a non-root user, only execution permissions are required on the file, not ownership

Ensure that HEALTHCHECK is being used. The HEALTHCHECK instruction tells Docker how to test a container to check that it is still working

Pinning an action to a full length commit SHA is currently the only way to use an action as an immutable release. Pinning to a particular SHA helps mitigate the risk of a bad actor adding a backdoor to the action's repository, as they would need to generate a SHA-1 collision for a valid Git object payload. When selecting a SHA, you should verify it is from the action's repository and not a repository fork.

Check if any apt-get installs don't use '--no-install-recommends' flag to avoid installing additional packages.
