==Introduction==
+
[https://wiki.servarr.com/en/docker-arm-synology Moved to the new wiki]
Synology only offer a docker package on their <code>x64</code> based NAS.  Using this method to install docker on an <code>aarch64</code> NAS is totally unsupported/untested and totally at your own risk.  It is entirely possible it will destroy your NAS.
 
 
 
==Summary==
 
 
 
The instructions below will:
 
# Place the docker binaries in <code>/usr/local/bin/</code>
 
# Create a docker config file <code>/usr/local/etc/docker/docker.json</code>
 
# Configure docker to save its data to <code>/volume1/docker/var</code>
 
# Create a script to start docker on boot at <code>/usr/local/etc/rc.d/docker.sh</code>
 
# Create a <code>docker</code> group
 
# Place a docker-compose script in <code>/usr/local/bin/</code>
 
 
 
==Installation==
 
Log in as <code>root</code> 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:
 
<pre>Done.  Please add your user to the docker group in the Synology GUI and reboot your NAS.</pre>
 
 
 
Do as it says:
 
# Add your user to the new <code>docker</code> group using the Synology GUI
 
# '''Reboot.''' 
 
 
 
Hopefully you have functioning <code>docker</code> and <code>docker-compose</code> commands, which should work when logged in as your normal user.
 
 
 
==Caveats==
 
# 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 <code>--network=host</code> (or <code>network: host</code> in 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 GUID==
 
If you want a GUI you can run Portainer using the following example compose:
 
 
 
<pre>
 
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:
 
</pre>
 
 
 
Place this in a file called <code>docker-compose.yml</code> in an otherwise empty directory.  Run:
 
docker-compose up -d
 
Visit <code>http://ip:9000</code> to complete setup (where <code>ip</code> 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.'''
