==Uninstall old docker versions==

This is an optional step in case your docker version is out of date:

sudo apt-get remove docker docker-engine docker.io containerd runc

==Install docker using the repository==

sudo apt-get update
sudo apt-get install \
ca-certificates \
curl \
gnupg

sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

echo \
"deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
"$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

==Start Docker==
Start docker using the following command:

$ sudo systemctl start docker

Enable the Docker service to start automatically on system boot by running the following command:

$ sudo systemctl enable docker

==Verify that Docker Engine is installed correctly ==
Run the hello-world image.

$ sudo docker run hello-world

This command will run a test container and display a message indicating that the installation is working properly.
