Install docker on debian 11

To install Docker on Debian 11, follow these steps:

1. Update existing package database:

   sudo apt update

2. Install prerequisites:

   Install required packages that allow apt to use packages over HTTPS.

   sudo apt install apt-transport-https ca-certificates curl software-properties-common gnupg

3. Add Docker's official GPG key:

   curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

4. Add the Docker repository:

   Add the Docker repository to your APT sources.

   echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

5. Update the package database again:

   sudo apt update

6. Install Docker:

   Now, you can install Docker using:

   sudo apt install docker-ce docker-ce-cli containerd.io

7. Start and enable Docker service:

   Ensure Docker starts automatically after boot.

   sudo systemctl start dockersudo systemctl enable docker

8. Verify Docker installation:

   Check if Docker is running correctly by running:

   sudo docker --version

If you see Docker's version number, the installation was successful.
