Docker service doesn't start after boot

Question

I am trying to figure out why my docker service doesn't run automatically on reboot.

Here it is:

$ sudo cat /etc/systemd/system/docker.service
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd --insecure-registry=some-registry

When I try: $ sudo systemctl enable docker.service nothing happens.

The status of this service under list-unit-files:

$ sudo systemctl list-unit-files | grep docker
docker.service           static

If I start the service manually (sudo systemctl start docker.service) it works as expected though.

Any ideas why?

The issue is because you have not specified any target in your service. You should change the service file as below

$ sudo cat /etc/systemd/system/docker.service
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd --insecure-registry=some-registry

[Install]
WantedBy=multi-user.target

After that run the below commands

systemctl daemon-reload 
systemctl disable docker
systemctl enable docker

And restart the system
