Properly document what should be done with dockerhub's arvados/jobs:latest image from 2 years ago
It is expected for some time now that workflow developers base their container images from specific version tags of the
arvados/jobs image, nevertheless we still have the
latest tag in DockerHub and it's pointing to a really old image.
We should review the current documentation and make the appropriate updates to let users know that the
latest tag shouldn't be used and it's there for legacy support purposes.
- Make sure the documentation does not tell users to use the arvados/jobs image, recommends people start from a standard image like debian-slim
- Alert any users that are using the legacy arvados/jobs:latest image they should stop doing that
- Should include a deprecation notice in 2.5 release notes that date N+3 months the image will be deleted
- when date N+3 months passes, delete the latest tag from docker hub (#19833)
