Use generated certificate in another container

[dj-fiorex]

Hello to all, i have a question about using the certificates generated by acme-companion in another container (mosquitto) of a docker-composer.
Right now i have a shared volume and the mosquitto container uses this volume to be able to read the certificates but I thing it is an hacky way because i also need to set the permissions of the certificates to the userId of the mosquitto user.
Is there a clean way to be able to use the same certificates with mosquitto or another container?

Thanks!

Hey,

I would be interest in a solution. My keycloak docker container uses internally the userid 1000.
I mounted the certs directory to the keycloak container. But it has problems to start because of permission problems. (user 1000 has no read permissions to the certs).
Further I can't change the owner of the certificates. It is changed back to root automatically.
