Howto – Install Docker on Debian

Set-Up docker on Debian:

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 - 

Verify that you now have the key with the fingerprint9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88, by searching for the last 8 characters of the fingerprint.

$ sudo apt-key fingerprint 0EBFCD88
pub 4096R/0EBFCD88 2017-02-22 Key fingerprint = 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88
uid Docker Release (CE deb) <docker@docker.com>
sub 4096R/F273FCD8 2017-02-22 

Use the following command to set up the stable repository. You always need the stable repository, even if you want to install builds from the edge or test repositories as well. To add the edge or test repository, add the word edge or test (or both) after the word stable in the commands below.

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

To install a specific version of Docker CE, list the available versions in the repo, then select and install:

 List the versions available in your repo:

$ apt-cache madison docker-ce docker-ce | 18.03.0~ce-0~debian | https://download.docker.com/linux/debian jessie/stable amd64 Packages 

Install a specific version by its fully qualified package name, which is the package name (docker-ce) plus the version string (2nd column) up to the first hyphen, separated by a an equals sign (=), for example, docker-ce=18.03.0.ce.

$ sudo apt-get install docker-ce=<VERSION_STRING> 

The Docker daemon starts automatically.

Verify that Docker CE is installed correctly by running the hello-world image.

$ sudo docker run hello-world
