1, Set up Docker's apt repository.
# Add Docker's official GPG key:
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/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg
# Add the repository to Apt sources:
echo
"deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian
"$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" |
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
2, Install the Docker packages.
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
3, Verify that the installation is successful by running the hello-world image:
sudo docker run hello-world
