Finally Debian 11 is released on August 14th, 2021, and this version is marked as a stable version. This tutorial will show you the steps on how to install Docker on a new fresh Debian 11 instance.
Prerequisites
- Debian 11
Install latest Docker version on Debian 11
Step 1. Update the apt package index:
sudo apt-get update
Step 2. Allow apt to use a repository over HTTPS:
sudo apt-get install \
apt-transport-https \
ca-certificates \
curl \
gnupg \
lsb-release
Step 3. Now add docker gpg key:
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
Step 4. We need to execute the following command to add the docker stable repository:
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
Step 5. To install the latest docker version, we need update the apt package index, and then install the latest version of docker:
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io
Install a specific Docker version on Debian 11
To install a specific Docker version you need to complete the above 4 steps (without executing Step 5) and run:
sudo apt-get install docker-ce=<VERSION_STRING> docker-ce-cli=<VERSION_STRING> containerd.io
Uninstall Docker Engine on Debian 11
If you decide to uninstall docker for some reason run:
sudo apt-get purge docker-ce docker-ce-cli containerd.io
sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd
