Custom app: docker volume mapping

[timconsidine]

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

[jbrichez]

@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

[timconsidine]

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

[jbrichez]

@timconsidine I'm using a pre-built image from docker hub

[timconsidine]

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]

Ok i understant but where is made the mapping exactly ?

EDIT: after some research, yes the app need to store some files

@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 ?

[girish]

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

[jbrichez]

@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.
