Through this tutorial, we will show you step-by-step how to install, configure, and uninstall docker on Ubuntu 22.04 or 20.04 system.

How to Install Docker Engine on Ubuntu 22.04

Here is a step-by-step guide to installing and configuring docker on Ubuntu 22.04 system:

Step 1 – Update System Dependencies

First of all, start terminal window and update the dependencies of the system, which you can do with this:

sudo apt update
sudo apt upgrade

Step 2 – Install Docker

Ensure you install the latest version of Docker from the official Docker repository. The official Ubuntu repository also has the Docker installation package, but it may not be the latest version.

Let’s play with some commands to install docker on Ubuntu 22.04 system; is as follows:

Install some packages which allow you to use the packages over HTTPS.

sudo apt install apt-transport-https ca-certificates curl software-properties-common

Add the GPG key of Docker repository.

curl -fsSL | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

Now add the Docker repository of Ubuntu 22.04 (jammy) to the apt sources.

echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Update the packages index and setup your server to install Docker from official Docker repo.

sudo apt update
sudo apt-cache policy docker-ce

Then you will receive an output similar to this: as is follow:

  Installed: (none)
  Candidate: 5:20.10.14~3-0~ubuntu-jammy
  Version table:
     5:20.10.14~3-0~ubuntu-jammy 500
        500 jammy/stable amd64 Packages
     5:20.10.13~3-0~ubuntu-jammy 500
        500 jammy/stable amd64 Packages

Execute the following command on command prompt to install Docker on ubuntu 22.04 system:

sudo apt install docker-ce

Once Docker is installed and the process is enabled to start on boot.

To check the status of Docker you can use the following command.

sudo systemctl status docker

The output will be like this.

● docker.service - Docker Application Container Engine
     Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
     Active: active (running) since Wed 2022-05-04 06:43:00 UTC; 2min 28s ago
TriggeredBy: ● docker.socket
   Main PID: 12995 (dockerd)
      Tasks: 8
     Memory: 38.6M
        CPU: 400ms
     CGroup: /system.slice/docker.service
             └─12995 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock

Step 3 – Configure Sudo permissions for Docker

If you want to run the docker command without sudo, so execute the following command with username on command prompt to the docker group:

sudo usermod -aG docker username

Restart SSH or open a new terminal to see the changes.

From now you use the docker command without sudo.

Step 4 – Using Docker Commands

Use the following command to view the system information about Docker; is as follows:

docker info

Download Docker Images

docker run hello-world

If the output you get is similar to the below then you can access and download images from Docker Hub.

Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
2db29710123e: Pull complete 
Digest: sha256:10d7d58d5ebd2a652f4d93fdd86da8f265f5318c6a73cc5b6a9798ff6d2b2e67
Status: Downloaded newer image for hello-world:latest

Hello from Docker!
This message shows that your installation appears to be working correctly.

Execute the following command to see downloaded images:

docker images

Docker Commands

Once we have started using Docker, will have many active and inactive containers.

Use the following command to view all active containers:

docker ps

Use the following command to view all containers which are active and inactive:

docker ps -a

Use the following command to view the latest container:

docker ps -l

To start a docker container, use docker start command followed by the Container ID or Container Name:

docker start container-id/name

Likewise, to stop a running container you can use the docker stop command followed by Container ID or Container Name:

docker stop container-id/name

If you no longer need the container you can remove the container with the docker rm followed by Container ID or Container Name:

docker rm container-id/name

To enter into interactive shell you can use the following command:

docker run -it container-id/name

Note that:- you can manually install commands inside the shell. For more details about docker commands use the docker run help command.

Step 5 – Uninstall Docker Ubuntu 22.04

Sometimes, you may need to completely remove or uninstall Docker in Ubuntu 20.0|22.04. You can do this by the following commands:

dpkg -l | grep -i docker

sudo apt-get purge -y docker-engine docker docker-ce docker-ce-cli

sudo apt-get autoremove -y --purge docker-engine docker docker-ce

sudo rm -rf /var/lib/docker /etc/docker

sudo rm /etc/apparmor.d/docker
