Docker is supported on these Ubuntu operating systems:
- Ubuntu Xenial 16.04 (LTS)
- Ubuntu Wily 15.10
- Ubuntu Trusty 14.04 (LTS)
- Ubuntu Precise 12.04 (LTS)
update your apt sources:
Docker’sAPTrepository contains Docker 1.7.1 and higher. To setAPTto use packages from the Docker repository:
-
Log into your machine as a user with
sudoorrootprivileges. -
Open a terminal window.
-
Update package information,ensure that APT works with the
httpsmethod,and that CA certificates are installed.$ sudo apt-get update $ sudo apt-get install apt-transport-https ca-certificates -
Add the new
GPGkey.$ sudo apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D -
Find the entry for your Ubuntu operating system.
The entry determines where APT will search for packages. The possible entries are:
Ubuntu version Repository Precise 12.04 (LTS) deb https://apt.dockerproject.org/repo ubuntu-precise mainTrusty 14.04 (LTS) deb https://apt.dockerproject.org/repo ubuntu-trusty main Wily 15.10 deb https://apt.dockerproject.org/repo ubuntu-wily main Xenial 16.04 (LTS) deb https://apt.dockerproject.org/repo ubuntu-xenial main Note: Docker does not provide packages for all architectures. Binary artifacts are built nightly,and you can download them from https://master.dockerproject.org. To install docker on a multi-architecture system,add an
[arch=...]clause to the entry. Refer toDebian Multiarch wikifor details. -
Run the following command,substituting the entry for your operating system for the placeholder
<REPO>.$ echo "<REPO>" | sudo tee /etc/apt/sources.list.d/docker.list -
Update the
APTpackage index.$ sudo apt-get update -
Verify that
APTis pulling from the right repository.When you run the following command,an entry is returned for each version of Docker that is available for you to install. Each entry should have the URL
https://apt.dockerproject.org/repo/. The version currently installed is marked with***.The output below is truncated.$ apt-cache policy docker-engine docker-engine: Installed: 1.12.2-0~trusty Candidate: -0~trusty Version table: *** -0~trusty 0 500 https://apt.dockerproject.org/repo/ ubuntu-trusty/main amd64 Packages 100 /var/lib/dpkg/status .1500 https://apt.dockerproject.org/repo/ ubuntu-trusty/main amd64 Packages .01.11500 https://apt.dockerproject.org/repo/ ubuntu-trusty/main amd64 PackagesFrom now on when you run
apt-get upgrade,APTpulls from the new repository.
Then,install Docker using the following:
-
Log into your Ubuntu installation as a user with
sudoprivileges. -
Update your
APTpackage index.$ sudo apt-get update -
Install Docker.
$ sudo apt-get install docker-engine -
Start the
dockerdaemon.$ sudo service docker start -
Verify
dockeris installed correctly.$ sudo docker run hello-worldThis command downloads a test image and runs it in a container. When the container runs,it prints an informational message. Then,it exits.
o create thedockergroup and add your user:
-
Log into Ubuntu as a user with
sudoprivileges. -
Create the
dockergroup.$ sudo groupadd docker
-
Add your user to
$ sudo usermod -aG docker $USER
Log out and log back in.
This ensures your user is running with the correct permissions.
Verify your work by runningdockerwithoutsudo.
$ docker run hello-world
