To install Docker CE, you need the 64-bit version of one of these Ubuntu versions:
- Bionic 18.04 (LTS)
- Artful 17.10
- Xenial 16.04 (LTS)
- Trusty 14.04 (LTS)
Docker CE is supported on Ubuntu on
s390x (IBM Z), and
ppc64le (IBM Power) architectures.
s390xlimitations: Packages for IBM Z and Power architectures are only available on Ubuntu Xenial and above.
Uninstall old versions
Older versions of Docker were called
docker-engine. If these are
installed, uninstall them:
$ sudo apt-get remove docker docker-engine docker.io
It’s OK if
apt-get reports that none of these packages are installed.
The contents of
/var/lib/docker/, including images, containers, volumes, and
networks, are preserved. The Docker CE package is now called
Supported storage drivers
Docker CE on Ubuntu supports
aufs storage drivers.
- For new installations on version 4 and higher of the Linux kernel,
overlay2is supported and preferred over
- For version 3 of the Linux kernel,
aufsis supported because
overlay2drivers are not supported by that kernel version.
If you need to use
aufs, you need to do additional preparation as
Install Docker CE
Install using the repository
Before you install Docker CE for the first time on a new host machine, you need to set up the Docker repository. Afterward, you can install and update Docker from the repository.
Set up the repository
$ sudo apt-get update
Install packages to allow
aptto use a repository over HTTPS:
$ sudo apt-get install \ apt-transport-https \ ca-certificates \ curl \ software-properties-common
Add Docker’s official GPG key:
$ curl -fsSL https://download.docker.com/linux/ubuntu/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.
$ 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) <email@example.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
test(or both) after the word
stablein the commands below. Note: The
lsb_release -cssub-command below returns the name of your Ubuntu distribution, such as
xenial. Sometimes, in a distribution like Linux Mint, you might need to change
$(lsb_release -cs)to your parent Ubuntu distribution. For example, if you are using
Linux Mint Rafaela, you could use
$ sudo add-apt-repository \ "deb [arch=amd64] https://download.docker.com/linux/ubuntu \ $(lsb_release -cs) \ stable"Note: Starting with Docker 17.06, stable releases are also pushed to the edge and test repositories. Learn about stable and edge channels.
Install Docker CE
$ sudo apt-get update
Install the latest version of Docker CE, or go to the next step to install a specific version:
$ sudo apt-get install docker-ceGot multiple Docker repositories?If you have multiple Docker repositories enabled, installing or updating without specifying a version in the
apt-get updatecommand always installs the highest possible version, which may not be appropriate for your stability needs.
To install a specific version of Docker CE, list the available versions in the repo, then select and install:
a. List the versions available in your repo:
$ apt-cache madison docker-ce docker-ce | 18.03.0~ce-0~ubuntu | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packagesb. Install a specific version by its fully qualified package name, which is package name (
docker-ce) “=” version string (2nd column), for example,
$ sudo apt-get install docker-ce=<VERSION>The Docker daemon starts automatically.
Verify that Docker CE is installed correctly by running the
$ 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 and exits.
Docker CE is installed and running. The
docker group is created but no users
are added to it. You need to use
sudo to run Docker commands.
Continue to Linux postinstall to allow
non-privileged users to run Docker commands and for other optional configuration
