Hello
This morning, I update my docker installation on ubuntu 22.04 to version 23.0.0.
I have a configuration to use another partition for my docker stuff, and I update my /usr/lib/systemd/system/docker.service
:
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
to
ExecStart=/usr/bin/dockerd -g /home/docker -H fd:// --containerd=/run/containerd/containerd.sock
And when I start docker.service after systemctl daemon-reload
, there is this message:
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
And systemctl status docker.service:
Ă— docker.service - Docker Application Container Engine
Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
Active: failed (Result: exit-code) since Fri 2023-02-03 15:36:28 CET; 24min ago
TriggeredBy: Ă— docker.socket

févr. 03 15:36:28 laurent-ubuntu-5 systemd[1]: Failed to start Docker Application Container Engine.
I try to remove --purge docker installation, and reinstall, but same error still here.
If I don’t change the /usr/lib/systemd/system/docker.service
, all works fine…
Have you this same problem?
After read the release notes, I undestand that my config must be update:
Remove the -g and --graph daemon options in favor of --data-root. docker/cli#3739
- These options have been hidden and deprecated since 17.05.
- Deprecation notice
So, after change my /usr/lib/systemd/system/docker.service
with
ExecStart=/usr/bin/dockerd --data-root /home/docker -H fd:// --containerd=/run/containerd/containerd.sock
instead of
ExecStart=/usr/bin/dockerd -g /home/docker -H fd:// --containerd=/run/containerd/containerd.sock
all works fine.
I hope it can be safe for other people.

I had the exact same symptoms as devintcreation , but with a slightly different ExecStart
value, and thus needed the same solution, just in a different location. The above answer pushed me in the right direction.
My systemctl status docker
was:
Ă— docker.service - Docker Application Container Engine
Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
Active: failed (Result: exit-code) since Wed 2023-04-19 15:20:34 AEST; 24s ago

Apr 19 15:20:34 docker-01 systemd[1]: Failed to start Docker Application Container Engine.
The difference being in the Process
line where I had not edited the ExecStart line at all.
I had done the Docker home location change in a daemon.json
file in /etc/docker/
.
In my /etc/docker/daemon.json
I had:
{
"graph": "/docker"
}
I believe this is the daemon.json equivalent to “-g” or “–graph” which is mentioned in the release notes.
When I changed “graph
” to “data-root
” docker started right up.
So, my /etc/docker/daemon.json in a working configuration is:
{
"data-root": "/docker"
}
I did not need to edit the /usr/lib/systemd/system/docker.service
at all in my situation.
For reference my Server: Docker Engine - Community version is 23.0.4
