Description

Instead of running github workflows or gitlab-ci on a :latest docker image, using fixed versions provides better stability.
It would therefore be awesome if dependabot could create pull requests with a bumped (but not :latest) image for a ci-setup.

I guess getting the versions of docker images from dockerhub is already implemented for the "docker" mode which bumps Dockerfiles.

Cheers

Research direction

Start by tracing the existing Docker mode that retrieves image versions from Docker Hub, then find how GitHub Actions workflows and ci-setup images are handled. Done means Dependabot can create pull requests that replace :latest Docker image references with fixed versions without changing other workflow behavior.
