To install Docker on you Debian distribution, first start off by updating the repositories.
If the user name your using Is not in the sudoers file. Add your username to sudoers file. Or login as root by typing “su”
Bullseye install docker
jill@VM-00:~$ sudo apt-get update [sudo] password for jill: Hit:1 http://deb.debian.org/debian bullseye InRelease Hit:2 http://security.debian.org/debian-security bullseye-security InRelease Hit:3 http://deb.debian.org/debian bullseye-updates InRelease Reading package lists... Done
jill@VM-00:~$ sudo apt-get install \
apt-transport-https \
ca-certificates \
curl \
gnupg \
lsb-release
jill@VM-00:~$ curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
jill@VM-00:~$ echo \ "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian \ $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
At this stage we need to update the repositories, as result you will see that docker repository was added.
jill@VM-00:~$ sudo apt-get update Hit:1 http://security.debian.org/debian-security bullseye-security InRelease Get:2 https://download.docker.com/linux/debian bullseye InRelease [43.3 kB] Hit:3 http://deb.debian.org/debian bullseye InRelease Hit:4 http://deb.debian.org/debian bullseye-updates InRelease Get:5 https://download.docker.com/linux/debian bullseye/stable amd64 Packages [4,475 B] Fetched 47.8 kB in 0s (102 kB/s) Reading package lists... Done
Finally proceed with the installation. If docker compose is needed, you have one more step to do.
jill@VM-00:~$ sudo apt-get install docker-ce docker-ce-cli containerd.io
Install docker compose.
jill@VM-00:~$ sudo apt-get install docker-compose
To verify if docker installed correctly, try to run the “hello-world” example as below.
jill@VM-00:~$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world

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
