Install Docker CE on Debian 10

Updated Thursday, March 12, 2020 by Linode Written by Linode

These steps install Docker Community Edition (CE) using the official Debian repositories. To install on another distribution, or to install on Mac or Windows, see the official installation page.

1. Remove any older installations of Docker that may be on your system:

   sudo apt remove docker docker-engine docker.io
   

2. Make sure you have the necessary packages to allow the use of Docker’s repository:

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

3. Add Docker’s GPG key:

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

4. Verify the fingerprint of the GPG key:

   sudo apt-key fingerprint 0EBFCD88
   

   You should see output similar to the following:

     
   pub   rsa4096 2017-02-22 [SCEA]
         9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88
   uid           [ unknown] Docker Release (CE deb) 
   sub   rsa4096 2017-02-22 [S]
   
   

5. Add the stable Docker repository:

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

   Note

   If you get an E: Package 'docker-ce' has no installation candidate error, this is because the stable version of Docker is not yet available. Therefore, you will need to use the edge / test repository.

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

6. Update your package index and install Docker CE:

   sudo apt update
   sudo apt install docker-ce
   

7. Add your limited Linux user account to the docker group:

   sudo usermod -aG docker $USER
   

   Note

   After entering the usermod command, you will need to close your SSH session and open a new one for this change to take effect.

8. Check that the installation was successful by running the built-in “Hello World” program:

   docker run hello-world
