Install Docker on Debian Jessie 8.0 (64-bit)

Docker is an open platform for developing, shipping, and running applications. Docker is designed to deliver your applications faster. With Docker you can separate your applications from your infrastructure AND treat your infrastructure like a managed application. Docker helps you ship code faster, test faster, deploy faster, and shorten the cycle between writing code and running code.

Docker does this by combining a lightweight container virtualization platform with workflows and tooling that help you manage and deploy your applications.

At its core, Docker provides a way to run almost any application securely isolated in a container. The isolation and security allow you to run many containers simultaneously on your host. The lightweight nature of containers, which run without the extra load of a hypervisor, means you can get more out of your hardware.

Surrounding the container virtualization are tooling and a platform which can help you in several ways:

getting your applications (and supporting components) into Docker containers
distributing and shipping those containers to your teams for further development and testing
deploying those applications to your production environment, whether it be in a local data center or the Cloud.

Install Docker on Debian essie 8.0 (64-bit)

Debian 8 comes with a 3.14.0 Linux kernel, and a package which installs all its prerequisites from Debian’s repository.

Note: Debian contains a much older KDE3/GNOME2 package called docker, so the package and the executable are called


To install the latest Debian package (may not be the latest Docker release):

$ sudo apt-get update
$ sudo apt-get install

To verify that everything has worked as expected:

$ sudo docker run -i -t ubuntu /bin/bash

Which should download the ubuntu image, and then start bash in a container.

Giving non-root access

The docker daemon always runs as the root user and the docker daemon binds to a Unix socket instead of a TCP port. By default that Unix socket is owned by the user root, and so, by default, you can access it with sudo.

If you (or your Docker installer) create a Unix group called docker and add users to it, then the docker daemon will make the ownership of the Unix socket read/writable by the docker group when the daemon starts. The docker daemon must always run as the root user, but if you run the docker client as a user in the docker group then you don’t need to add sudo to all the client commands. From Docker 0.9.0 you can use the -G flag to specify an alternative group.

Docker Example:

# Add the docker group if it doesn’t already exist.

$ sudo groupadd docker

# Add the connected user “${USER}” to the docker group.
# Change the user name to match your preferred user.
# You may have to logout and log back in again for
# this to take effect.

$ sudo gpasswd -a ${USER} docker

# Restart the Docker daemon.

$ sudo service docker restart
