In this tutorial, I will show you a script to install Docker and Docker Compose on Ubuntu 22.04.
Today more and more applications are available in containers with Docker, I regularly have to install a new machine on Ubuntu and have to install Docker and Docker Compose.
Personally, I prefer to install Docker from the official repositories rather than what Ubuntu offers to have a more recent version.
At the beginning, I would go to the Docker site each time and copy/paste lines of code onto the site, which is quite tedious.
Install Docker and Docker Compose with a script
To save time, I decided on a bash script which takes over the commands and here it is:
To use the script, copy its contents to a file on your server with the .sh extension then run the
sudo sh script-file-name.shThe script also works with Ubuntu 20.04
Verify that Docker is installed
To check that the installation is working properly you can enter these commands to have the versions of the Docker components.
docker --versionFor Docker Compose
docker compose versionLists of available Docker commands

Run 'docker COMMAND --help' for more information on a command.

For docker compose :
docker composeUsage: docker compose [OPTIONS] COMMAND
Define and run multi-container applications with Docker.

wait Block until the first service container stops
Run 'docker compose COMMAND --help' for more information on a command. Test Docker by running an image
To test that Docker is working correctly, you can run the hello-world image
sudo docker run hello-world
The image should return something like this:
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
719385e32844: Pull complete
Digest: sha256:c79d06dfdfd3d3eb04cafd0dc2bacab0992ebc243e083cabe208bac4dd7759e0
Status: Downloaded newer image for hello-world:latest
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
