Hey so I’m using nginx pm which already uses an mariadb so I want vaultwarden to be managed by that one as well.
I’m currently receiving this error message when I want to deploy the container:
Building with native build. Learn about native build in Compose here: https://docs.docker.com/go/compose-native-build/
vaultwarden is up-to-date

Seems like VW is running but the database is broken.
Here is the log of the VW container:

How did you start the existing mariadb container? You have to make sure that the containers are in the same network. By default containers in a docker-compose.yml are started in their own network. If you have an existing container you need to be more explicit about this:

Thanks for your reply! I actually start every docker-compose.yml with their more or less recommended template without any network specified. My npm and mariadb are running in the nginx-pm_default network with their default ports.
Okay. Also I forgot to mention that it’s probably not a good idea to start a new container with the same volumes mounted and at least performance-wise I don’t think there’s a benefit of trying to have two mariadb servers accessing the same data set (rather there’s probably the possibility of data corruption if you can manage to get it to work).
So (assuming that this is what’s happening here) you should either remove the mariadb service completely (and link the existing container/network) or start a separate mariadb container with it’s own volume to keep the services separate.
This is actually what I’m trying to achieve but since I’m a beginner I don’t know how to change the docker-compose.yml accordingly. Do you know how to do that?
I thought about the depends on funtion but this is apparently only for the compose file.
This is my docker-compose.yml for the nginx proxy manger which uses mariadb.
Sadly ChatGPT is not useable for me right now so I can’t get any help there.

I think by default Docker Compose calls the network <folder_name>_default (you should be able to confirm this by running docker network ls) so you could use that as a pre-existing network.The hostname of the mariadb container should just be resolvable by db once you link the vaultwarden container to the pre-existing network.
You should also be able to add a new user/database to the running mariadb container.

Thanks for your help Stefan!
I tried to change the docker-compose.yml but I’m having some problems with YAML sometimes. Do you know what’s my problem when I get the following error message:
In file './docker-compose.yml', network 'image' must be a mapping not a string.
As shown in the docker wiki example
I added the section above to my mariadb section.

I’m unsure how I would add another user to the db. Does this happen automatically when I enter other credentials like in this compose file?
