how to install docker engine on debian

Installing the Docker engine on a Debian-based system is relatively straightforward. Here are the basic steps:

Update the package list: Before installing any new packages, it's a good idea to update the package list to ensure that you have the latest version of Docker. Run the following command to update the package list:

sudo apt-get update

Install packages to allow apt to use a repository over HTTPS:

sudo apt-get install apt-transport-https ca-certificates curl gnupg2 software-properties-common

Add Docker's official GPG key:

 curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -

This step will add the Docker repository to your system's list of software sources.

Add the Docker repository to your system's list of software sources:

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"

This command will add the appropriate repository to your system based on the version of Debian that you're running.

Update the package list again:

sudo apt-get update

Install the Docker engine:

sudo apt-get install docker-ce

Verify that the Docker engine is running:

sudo systemctl status docker

This command should return the status of the Docker daemon and indicate that it is running.

Once the installation is complete, the Docker daemon will be running, and you can use the docker command to interact with it.

It's worth mentioning that the above steps are for installing the latest stable version of Docker engine, and you can install a specific version by using the package version along with the install command. If you wish to install the specific version. Make sure to check the version available on the official website before installing.
