What I expected to happen

container to start, like it has for some time. I’m not sure if it was an update to CentOS8 that caused it, or a new deployment of the container. I’m searched for a while but finding 5-6 year old errors that say it was patched and fixed but aren’t related to net data.

my docker-compose for starting net data:

netdata:
    image: netdata/netdata
    container_name: netdata
    hostname: plex.nomorestars.local # set to fqdn of host
    ports:
      - 19999:19999
    restart: unless-stopped
    cap_add:
      - SYS_PTRACE
    security_opt:
      - apparmor:unconfined
    volumes:
      - netdataconfig:/etc/netdata
      - netdatalib:/var/lib/netdata
      - netdatacache:/var/cache/netdata
      - /etc/passwd:/host/etc/passwd:ro
      - /etc/group:/host/etc/group:ro
      - /proc:/host/proc:ro
      - /sys:/host/sys:ro
      - /etc/os-release:/host/etc/os-release:ro

Hey @trekkie,

Although I am not proficient with plex, having used the container over the weekend and knowing a bit about containers, I think it’s not related to Netdata.

Due to the tech, I am almost certain that it should just “play”, since the netdata environment doesn’t change from container engine to container engine.

That being said, an error line in the code you supplied mentions that it was not possible to read proc. Can you verify that the docker runtime that you use allows this volume mount? - /proc:/host/proc:ro

For example, in balena, although it’s docker-container, in order to give access to proc, you have to pass a label.

thanks for pointing me in a direction, i’ll look into it. I’m relatively new to docker as well.
