Hi folks, I anticipated a little and created apache/polaris repo on DockerHub where we will be able to push our images:
https://hub.docker.com/r/apache/polaris I will deal with the secret to push directly from GitHub Action. For committers and PPMC members: if you want to administrate the DockerHub repository, please let me know, I will add your DockerHub user in the repository admin group. Regards JB
