Summary

The goal is to migrate an existing instance of Sonarr and Couch from a stand-alone CentOS 7 vm to a Docker container on a separate CentOS 7 vm running Docker. The idea is that Sonarr and Couch does not appear to need all of the overhead that comes with running an entire OS on a separate VM. We will attempt to consolidate resources leveraging containers as appropriate.

Layout

Virtual Environment - Proxmox

All of the host servers mentioned are virtual machines running CentOS 7 managed in a Proxmox environment.

TV Library - Plex Media Server

The existing NFS share on the Plex server was updated (/etc/exports) to allow the Docker server access.

Download Client - Deluge Server

The existing Deluge Server also has an NFS share that needs to be updated to allow the Docker server access.

TV Personal Video Recorder (PVR) - Sonarr

The existing server is it's own CentOS 7 virtual machine. We will be backing up the configuration data from the existing server and using it to migrate to a new Sonarr instance running in a Docker container on the Docker server.

Movie Personal Video Recorder (PVR) - CouchPotato

The existing server is it's own CentOS 7 virtual machine. We will be backing up the configuration data from the existing server and using it to migrate to a new Couch instance running in a Docker container on the Docker server.

Sonarr Work Flow

The main use for Sonarr is configuring it to monitor a location on the Deluge server for new TV shows and move them appropriately to the Plex server.

# main functionality
TV show episode --> downloaded by Deluge server --> managed by Sonarr instance --> lands appropriately on Plex server

Couch Work Flow

The main use for Couch is configuring it to monitor a location on the Deluge server for new movies and move them appropriately to the Plex server.

# main functionality
Movie --> downloaded by Deluge server --> managed by Couch instance --> lands appropriately on Plex server

Prep/Work

create sonarr config directory on docker server
scp the sonarr backup zip file to docker server
scp the couch backup ini file to docker server
unzip sonarr backup into sonarr config directory on docker server

Create Container

This is the command used to create the Sonarr container as per the Docker Hub page for the image.

docker create \
    --name sonarr \
    -p 8989:8989 \
    -e PUID=0 -e PGID=0 \
    -v /dev/rtc:/dev/rtc:ro \
    -v /app/config/sonarr:/config \
    -v /mnt/nfs/tvshows:/mnt/nfs/tvshows \
    -v /mnt/nfs/deluge/complete/tv:/mnt/nfs/deluge/complete/tv \
    linuxserver/sonarr

This is the command used to create the Couch container as per the Docker Hub page for the image.

docker create \
    --name=couchpotato \
    -v /app/config/couch:/config \
    -v /mnt/nfs/deluge/complete/movie:/mnt/nfs/deluge/complete/movie \
    -v /mnt/nfs/movies:/mnt/nfs/movies \
    -e PGID=0 -e PUID=0  \
    -e TZ=America/Chicago \
    -p 5050:5050 \
    linuxserver/couchpotato

Update Image/Container

# list running containers and grab id
docker ps -a

# stop running container based on id
docker stop <container id>

# remove container
docker rm <container id>

# list images and grab id
docker images

# remove image
docker rmi <image id>

# pull down latest update
docker pull <repo/image>

# create image
<use create commands above>

# list new container id's
docker ps -a

# start container with updated image
docker start <container id>
