Robert Munteanu commented on SLING-11701:
-----------------------------------------
Thanks for the report and links to documentation [~enorman]. I suspect this
happens because we are running multiple builds in parallel, and they sometimes
land on the same node. I have prepared a tentative fix with
https://github.com/apache/sling-org-apache-sling-starter/pull/81 .
> Starter CI builds are sometimes failing with an error about a conflict with

> The docker-maven-plugin documentation indicates that the containerNamePattern

> The documentation states that the default containerNamePattern value is
> "%n-%i". The "%i" segment of the pattern is supposed to be an index which is

> to be working for us, so maybe a different value would work more reliably?
