Is your feature request related to a problem? Please describe.

The palantir gradle docker plugin is end of life, see https://github.com/palantir/gradle-docker :

This repo is on life support only - although we will keep it working, no new features are accepted;

While they still do releases with updated dependency versions, we don't know how long this will last.

Describe the solution you'd like

Research alternative plugins that are better maintained. Here is the result of a quick search:

• https://github.com/lamba92/gradle-docker-plugin
• https://github.com/gesellix/gradle-docker-plugin
• https://github.com/rcw3bb/simple-docker

Describe alternatives you've considered (Optional)

Continue using https://github.com/palantir/gradle-docker and hope it remains maintained.
