    Are you running docker from the host ?
    Normally you should build a Dockerfile

      @timconsidine I have connected my cloudron cli to my cloudron instance and i'm running command from my computer:

      cloudron install --image hotio/jellyseerr
      

      No i don't think the config will change

        Ok but is this image built for Cloudron ? Or you’re using a pre-built image ?

            If the config is not ever going to change, it can be read-only and included in the app’s files under /app/code.

                @jbrichez in the Dockerfile, you can just symlink /config (or whatever) to say /app/data/config . The mapping is created in the Dockerfile.

                  I successfully started the app then when i check the container's volume I can see that:

                  [{bind  /media/movies /media/movies   true rprivate} {bind  /home/yellowtent/appsdata/4a224e49-5a30-49ae-bb2b-2b22731ab6ed/data /app/data   true rprivate} {volume 585faa40fe07d43726062f11d0530fad796806b03a3c1c39daab3a9a86b14542 /var/lib/docker/volumes/585faa40fe07d43726062f11d0530fad796806b03a3c1c39daab3a9a86b14542/_data /tmp local  true } {volume 28fcf47257a3b52162a2998df0eff0b325570c0cef49478f37cff3ecea7d0fda /var/lib/docker/volumes/28fcf47257a3b52162a2998df0eff0b325570c0cef49478f37cff3ecea7d0fda/_data /run local  true }]
                  

                  There is my question answer probably...
                  This is the mapping I was looking for 🙂

                  When we used the cloudron cli, behind you automatically create a volume and attached it my custom app...
                  I didn't see that in the doc. Is it written somewhere ?

                    @jbrichez maybe you are asking for https://docs.cloudron.io/packaging/cheat-sheet/#filesystem ?

                      @girish I think it is. But this was not really clear when i read it the first time

                        Still, a Cloudron App should not need a volume by default.

                        Like my work? Consider donating a drink. Cheers!
