Newbie: How to start openproject in a container @localhost

Hi
I’m totally new with this stuff and have to learn

Finally, with help of portainer I got the container : openproject
BUT I’m NOT able to get the APP started!! (Stupid)

PLS Help a desperate Newbie

PS: Is there a better tool than portainer to handle docker for a Beginner?

May I suggest to build up actual Dock knowledge first: https://container.training/intro-selfpaced.yml.html
The best tool is worth nothing if you don’t know how to use it properly…

That’s right!
