Add /etc/systemd/system/docker.service.d/override.conf
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd

I'm on a Synology NAS and I don't have the folder /etc/systemd/system/docker.service.d/override.conf ??? Any help on how to do step 2?

For everyone finding this page and looking for instructions for Synology's new Container Manager,

  1. sudo vi /var/packages/ContainerManager/etc/dockerd.json

change to:
{"data-root":"/var/packages/ContainerManager/var/docker","log-driver":"db","registry-mirrors":[],"storage-driver":"aufs","hosts": ["tcp://0.0.0.0:2375", "unix:///var/run/docker.sock"]}

(basically add the stuff from the original step 1 to the end, without the curly-brackets {} )

  1. systemctl daemon-reload

  2. sudo systemctl restart pkg-ContainerManager-dockerd

You may need to repeat these steps when the Container Manager package gets updated. So far it's working for me

Hi,bro. I'm trying to add the proxy option for the dockerd.json,there is some problem for me.
I had read the docs of how to set the value of daemon-proxy,but the error still exsit.

  "proxies": {
    "http-proxy": "http://proxy.example.com:80",
    "https-proxy": "https://proxy.example.com:443",
    "no-proxy": "*.test.example.com,.example.org",
  }

unable to configure the Docker daemon with file /var/packages/ContainerManager/etc/dockerd.json: the following directives don't match any configuration option: http-proxy, https-proxy, no-proxy

{"data-root":"/var/packages/ContainerManager/var/docker","log-driver":"db","proxies":{"http-proxy":"http://127.0.0.1:7890","https-proxy":"http://127.0.0.1:7890","no-proxy":"localhost,127.0.0.1"},"registry-mirrors":[],"storage-driver":"aufs"}
can you give me some help? appreciate it.

Sorry @honue , I don't know as I don't use proxies. Maybe Synology doesn't support those options. They are also using a slightly older version of docker. v20.10.23, build 876964a
