@samspade21 Heres the bug that is related to this issue: Can't create custom containersI am on v.8.3.13 and I have the same trouble. I have another custom container defined in mycontainers that was deployed on version 7 and it re-deploys and works great. However, my new container (pihole.yml) does not appear in PG Box (any option) and when you type pihole (value of pgrole in the ansible file) it is not found.
@Sn0wed I personally find the portainer UI to create containers to be clunky and prefer using the ansible pg template. That being said, a bug is a bug.
