The Docker documentation[1] recommends using the `usermod` command for adding a user to the `docker` group. The previous `adduser` command only worked for Debian-based systems and is symlinked to `useradd` on my Fedora 43 by default. I also add the step to create the `docker` group which wasn't present previously and is a pre-req for adding $USER to the `docker` group.

##### 2. Create the `docker` group and add yourself to it:
|
|
|
|
```console
|
|
$ sudo groupadd docker
|
|
$ sudo usermod -aG docker $USER
|
|
```
|
|
|
|
You will need to log out and log back in (or reboot) for this change to take effect.
|
|
If it worked, you will see `docker` in your list of groups:
|
|
|
|
```console
|
|
$ groups | grep docker
|
|
YOURUSERNAME adm cdrom sudo dip plugdev lpadmin sambashare docker
|
|
```
|
|
|
|
##### 3. Make sure the Docker daemon is running
|
|
|
|
Docker runs as a background service (daemon), which must be running for Docker commands to work.
|
|
|
|
If you had previously installed and removed an older version of
|
|
Docker, an [Ubuntu
|
|
bug](https://bugs.launchpad.net/ubuntu/+source/docker.io/+bug/1844894)
|
|
may prevent Docker from being automatically enabled and started after
|
|
installation. You can check using the following:
|
|
|
|
```console
|
|
$ systemctl status docker
|
|
● docker.service - Docker Application Container Engine
|
|
Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
|
|
Active: active (running) since Mon 2019-07-15 23:20:46 IST; 18min ago
|
|
```
|
|
|
|
If the service is not running, you'll see `Active: inactive (dead)` on
|
|
the second line, and will need to enable and start the Docker service
|
|
using the following:
|
|
|
|
```console
|
|
$ sudo systemctl unmask docker
|
|
$ sudo systemctl enable docker
|
|
$ sudo systemctl start docker
|
|
```
