Installing Docker and Docker Compose on Debian 12

Before installing Docker, ensure your Debian system is up-to-date with the following command: sudo apt update && sudo apt upgrade -y Shell Once your system is updated, install the necessary packages to allow apt to use a repository over HTTPS: sudo apt install apt-transport-https ca-certificates curl software-properties-common gnupg2 -y Shell Next, add the official GPG key of Docker: curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add - Shell Add the Docker repository to APT sources: echo "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list Shell Update your package index and install Docker CE (Community Edition): sudo apt update && sudo apt install docker-ce -y Shell To ensure Docker starts on boot, use the following command: sudo systemctl enable docker Shell Verify the Docker installation by running the hello-world image: sudo docker run hello-world Shell Installing Docker Compose on Debian 12 Docker Compose is a tool for defining and running multi-container Docker applications. To install Docker Compose, first, download the latest version from the official GitHub repository: sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose Shell Next, set the appropriate permissions to make the binary executable: sudo chmod +x /usr/local/bin/docker-compose Shell Verify the installation by checking the version of Docker Compose: docker-compose --version Shell At this point, Docker and Docker Compose are installed and ready for use on your Debian 12 system.
