$ sudo apt-get remove docker docker-engine docker.io containerd runc

The contents of /var/lib/docker/, including images, containers, volumes, and networks, are preserved. The Docker Engine package is now called docker-ce

Installation methods

Install using the repository

SET UP 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 \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \
    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 fingerprint 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88, by searching for the last 8 characters of the fingerprint.

Use the following command to set up the stable repository. To add the nightly or test repository, add the word nightly 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"

INSTALL DOCKER ENGINE

Update the apt package index, and install the latest version of Docker Engine and containerd, or go to the next step to install a specific version:

 $ sudo apt-get update
 $ sudo apt-get install docker-ce docker-ce-cli containerd.io

To install a specific version of Docker Engine, 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 | 5:18.09.1~3-0~debian-stretch | https://download.docker.com/linux/debian stretch/stable amd64 Packages
  docker-ce | 5:18.09.0~3-0~debian-stretch | https://download.docker.com/linux/debian stretch/stable amd64 Packages
  docker-ce | 18.06.1~ce~3-0~debian        | https://download.docker.com/linux/debian stretch/stable amd64 Packages
  docker-ce | 18.06.0~ce~3-0~debian        | https://download.docker.com/linux/debian stretch/stable amd64 Packages
  ...

Install a specific version using the version string from the second column, for example, 5:18.09.1_3-0debian-stretch

$ sudo apt-get install docker-ce=<VERSION_STRING> docker-ce-cli=<VERSION_STRING> containerd.io

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

$ sudo docker run hello-world
