Hi,
At teiid.io I read that docker images can be obtained from https://hub.docker.com/r/teiid/teiid/ . This docker hub page does say "This image is no longer being maintained. Please utilize https://hub.docker.com/r/jboss/teiid/ instead." in the description.
Is the first or the second one the preferred one? I see that the latest builds were published at the first site.
This is a little in flux at this point. See the discussion on [TEIID-5372] Enhance docker support - JBoss Issue Tracker
We'll update teiid.io appropriately.
