Docker ARM Synology
Synology only offer a docker package on their
x64 based NAS. Using this method to install docker on an
aarch64 NAS is totally unsupported/untested and totally at your own risk. It is entirely possible it will destroy your NAS.
The instructions below will:
- Place the docker binaries in
- Create a docker config file
- Configure docker to save its data to
- Create a script to start docker on boot at
- Create a
- Place a docker-compose script in
Log in as
root to your synology. Execute the following command:
curl https://gist.githubusercontent.com/ta264/2b7fb6e6466b109b9bf9b0a1d91ebedc/raw/7b11f25c3dce181faa5206aed8051f176cc4e406/get-docker.sh | sh
If all goes well you should see the message:
Done. Please add your user to the docker group in the Synology GUI and reboot your NAS.
Do as it says:
- Add your user to the new
dockergroup using the Synology GUI
Hopefully you have functioning
docker-compose commands, which should work when logged in as your normal user.
- It seems most ARM Synology don't support seccomp, so the docker container has unfettered access to your system (even more so than with a regular docker).
- Again, due to Synology constraints, all containers need to use
network: hostin compose) and everything will be directly accessible from the host. There are no port maps.
- Obviously you can only run aarch64 images, but most hotio and linuxserver images offer an aarch64 version.
Setting up a docker GUI
If you want a GUI you can run Portainer using the following example compose:
version: '2' services: portainer: image: portainer/portainer restart: unless-stopped network_mode: host volumes: - /var/run/docker.sock:/var/run/docker.sock - portainer_data:/data volumes: portainer_data:
Place this in a file called
docker-compose.yml in an otherwise empty directory. Run:
docker-compose up -d
http://ip:9000 to complete setup (where
ip is the IP address of your synology).
Setting up Sonarr/Radarr/Lidarr/Readarr
For guidance setting up Sonarr/Radarr/Lidarr/Readarr, see the Docker Guide, and remember caveat 2 above.
