docker

Can I install Docker on Synology DS418?

Is there a way to install Docker on Synology DS418 ?

I had try this with this aarch64/docker-20.10.6.tgz.

Here are the step I did:

  1. Download static docker binary at https://download.docker.com/linux/static/stable/aarch64/ . I choose the aarch64/docker-20.10.6.tgz, but I am maybe mistaking here.

  2. tar xzvf /path/to/.tar.gz

  3. sudo cp docker/* /usr/bin/

  4. create the /etc/docker/daemon.json configuration file with the following configuration:

{
  "storage-driver": "vfs",
  "iptables": false,
  "bridge": "none"
}
  1. sudo dockerd &

I received this error when I do the step 5.

Thank you very much

Solution

  • All you're missing is:

    sudo synogroup --add docker $USER

    If you run this command as a non-root user, that user will be able to execute docker commands without sudo.

    If you don't want this, try running the command as root or

    sudo synogroup --add docker

    may work. But I haven't tested either these latter two approaches.
