t.s.DeferredServletContainerInitializers : Error starting Tomcat context.

[Stephan-P]

What are you trying to do?

I am trying to install Grimmory Docker in openmediavault Compose

What's happening instead?

• The Grimmory-maria-db goes up Healthy
• The Grimmory-server keeps restarting

Checking the logs, the following ERROR jumps out:
t.s.DeferredServletContainerInitializers : Error starting Tomcat context.

Your setup

• Grimmory version: v3.2.2 as well as latest v3.2.4

Compose:

Before submitting

• I've searched existing discussions and I can't find anything that looks like my problem
• I've reviewed this report and have completed it as fully as I can

Looks like you're failing to connect to the database.

Looks kinda like you meant to have both a default & web-proxy network.

Grimmory explicitly only has the web-proxy network, I think you need to add default to it since you're specifying networks there.

[Stephan-P]

Thanks, @imnotjames.
Fixing the networks like you described fixed that issue.

But then I ran into another error re. database connection. Something about passwords...
After shortening the alphanumeric codes to a more reasonable 8 characters everything went along just fine.
(I didn't know that mysql root passwords need to be < 32 chars)
