To add a user to the docker user group
usermod -aG docker $USER
If you want to add a different user, replace $USER
with an existing username.
Check the docker version,
docker --version
Output:
root@ubuntu23:~# docker --version
Docker version 24.0.7, build 24.0.7-0ubuntu2
Test docker using the hello-world
container.
docker run hello-world
Output:
root@ubuntu23:~# docker run hello-world
Unable to find image 'hello-world:latest' locally

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
