Hi, During my work on the Docker Images for the Starter I found out that building only for tags makes it very hard to test out Docker builds.
I have forked the repository and built it using my Docker Hub account, but that unfortunately requires a paid Docker account, and I think we should not impose that limit on contributors. Given a statement from the ASF infra [1] that the DockerHub is not an official ASF release channel and we can publish images as we see fit, I would like to propose that we publish the master branch as apache/sling:snapshot for each build. FWIW, you can see the in-progress images at [2]. Thoughts? Thanks, Robert [1]: https://issues.apache.org/jira/browse/INFRA-22533?focusedCommentId=17445463 [2]: https://hub.docker.com/r/rombert/org-apache-sling-starter
