Install using the apt repository

Before you install Docker Engine for the first time on a new host machine, you need to set up the Docker apt repository. Afterward, you can install and update Docker from the repository.

1. Set up Docker's apt repository.

   # Add Docker's official GPG key:
   sudo apt update
   sudo apt install ca-certificates curl
   sudo install -m 0755 -d /etc/apt/keyrings
   sudo curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc
   sudo chmod a+r /etc/apt/keyrings/docker.asc
   
   # Add the repository to Apt sources:
   sudo tee /etc/apt/sources.list.d/docker.sources <<EOF
   Types: deb
   URIs: https://download.docker.com/linux/debian
   Suites: $(. /etc/os-release && echo "$VERSION_CODENAME")
   Components: stable
   Signed-By: /etc/apt/keyrings/docker.asc
   EOF
   
   sudo apt update
   

To install the latest version, run:

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