1.Install Docker Engine on Debian
1 Install using the repository.Update the apt package index and install packages to allow apt to use a repository over HTTPS:
sudo apt-get update sudo apt-get install \ ca-certificates \ curl \ gnupg \ lsb-release
2 Add Docker’s official GPG key:
sudo mkdir -p /etc/apt/keyrings curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
3 Use the following command to set up the repository:
echo \ "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian \ $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
4 Install Docker Engine
sudo apt-get update sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin
5 The docker installer uses iptables for nat. Unfortunately Debian uses nftables. You can convert the entries over to nftables or just setup Debian to use the legacy iptables.
sudo update-alternatives --set iptables /usr/sbin/iptables-legacy sudo update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy sudo service docker start
2 Test Docker
sudo docker run hello-world
2 Check docker service status
sudo systemctl status docker
And it shows this.
