This article is going to teach you how to Install Docker on Ubuntu 22.04. Docker is a group of platform as a service (PaaS) solutions that provide software in containers using OS-level virtualization. There are two tiers to the service: free and premium. Containers are self-contained, containing their own software, libraries, and configuration files, and communicating with one another via well-defined channels. Containers require fewer resources than virtual machines since they all share the services of a single operating system kernel. Docker Engine is the program that runs the containers. Docker, Inc. founded it in 2013 and continues to develop it.

- In case you want docker to run automatically on Ubuntu 22.04 every time you turn on your system, enable that functionality using the following command.
sudo systemctl enable docker.service- Check Docker version you installed using the command below.
sudo docker versionSample output
Client: Version: 20.10.7 API version: 1.41 Go version: go1.13.8 Git commit: 20.10.7-0ubuntu5~20.04.2 Built: Mon Nov 1 00:34:17 2021 OS/Arch: linux/amd64 Context: default Experimental: true Server: Engine: Version: 20.10.7 API version: 1.41 (minimum version 1.12) Go version: go1.13.8 Git commit: 20.10.7-0ubuntu5~20.04.2 Built: Fri Oct 22 00:45:53 2021 OS/Arch: linux/amd64 Experimental: false containerd: Version: 1.5.5-0ubuntu3~20.04.1 GitCommit: runc: Version: 1.0.1-0ubuntu2~20.04.1 GitCommit: docker-init: Version: 0.19.0 GitCommit:
Create Docker Container on Ubuntu 22.04
- To download any software, use the
docker pullcommand followed by the name of the package. e.g.
docker pull hello-worldSample output
Using default tag: latest latest: Pulling from library/hello-world 2db29710123e: Pull complete Digest: sha256:97a379f4f88575512824f3b352bc03cd75e239179eea0fecc38e597b2209f49a Status: Downloaded newer image for hello-world:latest docker.io/library/hello-world:latest
Run Docker Image on Ubuntu 22.04
- Run the downloaded image using
docker runcommand followed by package name. e.g.
docker run hello-worldSample output
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
Share images, automate workflows, and more with a free Docker ID:
https://hub.docker.com/
For more examples and ideas, visit:
https://docs.docker.com/get-started/
- List all containers using the command below.
docker container ls -aSample output
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 8b3d4ba1ef31 hello-world "/hello" 20 minutes ago Exited (0) 20 minutes ago youthful_wozniak
- To get a list of all the Docker images that have been installed type the following command.
docker images- Use the following command to see the current CPU, RAM, and network use of running images.
docker stats- Check Docker’s network configuration using the command below.
docker network ls- You can start docker using
docker startcommand followed by container ID e.g.
docker start 8b3d4ba1ef31- To stop docker container, use
docker stopcommand followed by container ID.
docker stop 8b3d4ba1ef31- You have reached the end of the article, Congratulations. You have learned how to Install docker on Ubuntu 22.04.
