带有安装文件的Docker挂载卷目录

Question

I'm working on building a Docker image for Plex Media server. I'm trying to integrate it with Plex Remote Transcoder which requires access to /var/lib/plexmediaserver on the container. This directory is the install directory for Plex.

My problem is that mounting a volume on startup just mounts the host directory to the container.

How do I mount a populated directory inside the container to my host?

Answer 1

You create and mount data volume container

Your Plex Media image declares a volume for /var/lib/plexmediaserver, and its Dockerfile make sure that /var/lib/plexmediaserver is properly filled.

Then any plex remote transcoder container would be run with --volumes-from <plexMediaServerContainer> : it would see the content of /var/lib/plexmediaserver in its container.
