Installation of Docker engine on Debian 11 bullseye distribution<\/strong><\/h2>\n
The installation of Docker will complete into the number of steps, which are provided below:<\/p>\n
Step 1: Remove old Docker packages<\/strong><\/h3>\n
If you installed Docker on your system before then, first you need to uninstall all older packages along with the dependencies called docker-engine or docker. However, the uninstallation process would not remove existing docker images, files, and networks that are present in the \/var\/lib\/docker\/ directory. So, run the below-mentioned command to uninstall the older docker version:<\/p>\n
$ sudo apt remove -y docker docker-engine docker.io containerd runc<\/pre>\n
Step 2: Install important Docker\u2019s packages\u00a0<\/strong><\/h3>\n
Refresh the apt packages repository list by using the below-given command:<\/p>\n
$ sudo apt update<\/pre>\n
Now, install some important required packages for the support the of HTTPS method by using the following command:<\/p>\n
$ sudo apt install -y apt-transport-https ca-certificates curl gnupg2 software-properties-common<\/pre>\n
The following output will print after installing all the above-required Docker packages.<\/p>\n

<\/p>\nStep 3: Add the Docker\u2019s Repository<\/strong><\/h3>\n
In this step, import the Docker\u2019s repository GPG key on your system by running the below-mentioned command:<\/p>\n
$ curl -fsSL https:\/\/download.docker.com\/linux\/debian\/gpg | sudo gpg --dearmor -o \/usr\/share\/keyrings\/docker-archive-keyring.gpg<\/pre>\n
![](\"http:\/\/linuxways.net\/wp-content\/uploads\/2021\/10\/word-image-56.png\")
<\/p>\nOnce you have included the GPG key, run the following command to add the Docker\u2019s repository to the source list of your system:<\/p>\n
$ 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<\/pre>\n
![](\"http:\/\/linuxways.net\/wp-content\/uploads\/2021\/10\/word-image-57.png\")
<\/p>\nAfter adding a new docker\u2019s repository, refresh the apt repository by executing the \u2018sudo apt update\u2019 command.<\/p>\n
Step 4: Docker installation on Debian 11 system<\/strong><\/h3>\n
Once you setup the docker\u2019s repository on your Debian 11 bullseye system, install the Docker engine with the help of the following \u2018apt\u2019 command:<\/p>\n
$ sudo apt install -y docker-ce docker-ce-cli containerd.io<\/pre>\n
![](\"http:\/\/linuxways.net\/wp-content\/uploads\/2021\/10\/word-image-58.png\")
<\/p>\nCheck the installation of Docker (CE) on the Debian 11 system by showing the information about the installed Docker\u2019s version as follows:<\/p>\n
$ docker --version<\/pre>\n
The installed docker version should display on the terminal window, which is also shown in the below-given screenshot:<\/p>\n
![](\"http:\/\/linuxways.net\/wp-content\/uploads\/2021\/10\/word-image-59.png\")
<\/p>\nCheck the running status of the docker service by using the \u2018systemctl\u2019 command as follows:<\/p>\n
$ sudo systemctl status docker<\/pre>\n
![](\"http:\/\/linuxways.net\/wp-content\/uploads\/2021\/10\/word-image-60.png\")
<\/p>\nStep 5: Test Docker installation<\/strong><\/h3>\n
To test the Docker installation on your system, run the \u2018hello-world\u2019 docker contained by executing the below-mentioned command:<\/p>\n
$ sudo docker run hello-world<\/pre>\n
The following output shows on the terminal that verifies the correct installation of the Docker engine on your Debian 11 bullseye distribution.<\/p>\n

<\/p>\nConclusion<\/strong><\/h2>\n
Congratulations! The Docker engine is installed on the Debian 11 system. We explored different commands in this article for the installation of the Docker engine on the Debian 11 bullseye system. In the next coming articles, we will also show you how to allow access to non-root users to execute the docker commands. Thanks!<\/p>\n
