Originally created by @Timeeee on GitHub.

I'm using the raspberry-image.

Using the docker-run command from the wiki doesn't set the containers host port correctly.

running

docker run -d --name bitwarden -v /bw-data/:/data/ -p 8080:8080 bitwardenrs/server:raspberry

adds the container with exposed port 8080, but the host port is set to 80. This leads to issues as I have another service running with host-port 80.

I didn't try using a fixed IP with port, as this is not possible in my environment.

I assumed there is a way to change the host port itself (not the forwarding) with -p as well. So there is no way to change the host port, which is in this case fixed to 80, right?

edit: I will play around some more with the settings, looks like I might have messed up something. Will give feedback once I did that. Sorry for creating the issue in the first place @mprasil !

Fantastic work btw :)

Well you were asking about the host side port as that's where the conflict is. I assume that bitwarden_rs will never conflict with the default port 80 inside the container as it's the only thing running inside the container.

If for some reason you really want to change the port where bitwarden_rs listens inside the container, you can do that by setting the ROCKET_PORT variable. But you'd have adapt the port forward as well: -e ROCKET_PORT=2345 -p 8080:2345

-p sets the port forwarding. So if you want to expose port 80 in the container as 8080 on the host you need to do -p 8080:80.
