Important

Docker Engine - Community users should go to Get Docker Engine - Community for Ubuntu instead of this topic.

Prerequisites

Confirm that all prerequisites are met before installing Docker Engine - Enterprise on Ubuntu.

The product URL associated with your trial or subscription is required to install Docker Engine - Enterprise, which can be attained using the following procedure (note that these instructions apply to Docker on Ubuntu and for Docker on Linux, which includes access to Docker Engine - Enterprise for all Linux distributions):

  1. Go to https://hub.docker.com/my-content.
  2. Each subscription or trial you have access to is listed. Click the Setup button for Docker Enterprise Edition for Ubuntu.
  3. Copy the URL from the field labeled Copy and paste this URL to download your Edition.

Use this URL when you see the placeholder text <DOCKER-EE-URL>.

To learn more about Docker Engine - Enterprise, see Docker Enterprise Edition.

OS requirements

To learn more about software requirements and supported storage drivers, check the compatibility matrix.

Note

IBM Z (s390x) is supported for Docker Engine - Enterprise 17.06.xx only.

Uninstall old versions

Use the apt-get remove command to uninstall older versions of Docker Engine - Enterprise (called docker or docker-engine). In addition, if you are upgrading from Docker Engine - Community to Docker Engine - Enterprise, remove the Docker Engine - Community package.

$ sudo apt-get remove docker docker-engine docker-ce docker-ce-cli docker.io

The apt-get command may report that none of the packages are installed.

Note

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

Extra steps for aufs

For Ubuntu 16.04 and higher, the Linux kernel includes support for overlay2, and Docker Engine - Enterprise uses it as the default storage driver. If you need to use aufs instead, be aware that it must be manually configured.

Install Docker Engine - Enterprise

Docker Engine - Enterprise can be installed either via Docker repositories, or by downloading and installing the DEB package and thereafter manually managing all upgrades. The Docker repository method is recommended, for the ease it lends in terms of both installation and upgrade tasks. The more manual DEB package approach, however, is useful in certain situations, such as installing Docker on air-gapped system that have no access to the Internet.

Install using the repository

Naturally, to install Docker Engine - Enterprise on a new host machine using the Docker repository you must first set the repository up on the machine.

Set up the repository

  1. Update the apt package index.

    $ sudo apt-get update

  2. Install packages to allow apt to use a repository over HTTPS.

    $ sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    software-properties-common

  3. Temporarily add a $DOCKER_EE_URL variable into your environment (it persists only up until you log out of the session). Replace <DOCKER-EE-URL> with the URL you noted down in the prerequisites.

      $ DOCKER_EE_URL="<DOCKER-EE-URL>"

  4. Temporarily add a $DOCKER_EE_VERSION variable into your environment.

     $ DOCKER_EE_VERSION=19.03

    Note

    If you need to run Docker Enterprise 2.0, refer to the following:

    • 18.09 - Docker Enterprise Edition 2.1 (Docker Engine, UCP, and DTR).
    • 18.03 - Older Docker Engine - Enterprise only release
    • 17.06 - Docker Enterprise Edition 2.0 (Docker Engine, UCP, and DTR).

  5. Add Docker’s official GPG key using your customer Docker Engine - Enterprise repository URL.

    $ curl -fsSL "${DOCKER_EE_URL}/ubuntu/gpg" | sudo apt-key add -

  6. Verify that you now have the key with the fingerprint DD91 1E99 5A64 A202 E859 07D6 BC14 F10B 6D08 5F96, by searching for the last eight characters of the fingerprint. Use the command as-is. It works because of the variable you set earlier.

     $ sudo apt-key fingerprint 6D085F96

 pub   4096R/0EBFCD88 2017-02-22
       Key fingerprint = DD91 1E99 5A64 A202 E859  07D6 BC14 F10B 6D08 5F96
 uid                  Docker Release (EE deb) <docker@docker.com>
 sub   4096R/6D085F96 2017-02-22

  7. Set up the stable repository, using the following command as-is (which works due to the variable set up earlier in the process).

    $ sudo add-apt-repository \
   "deb [arch=$(dpkg --print-architecture)] $DOCKER_EE_URL/ubuntu \
   $(lsb_release -cs) \
   stable-$DOCKER_EE_VERSION"

    Note

    The included lsb_release -cs sub command returns the name of your Ubuntu distribution, for example, xenial.

Install Docker Engine - Enterprise

  1. Update the apt package index.

    $ sudo apt-get update

  2. Install the latest version of Docker Engine - Enterprise and containerd, or go to the next step to install a specific version. Any existing installation of Docker is replaced.

    $ sudo apt-get install docker-ee docker-ee-cli containerd.io

    Warning

    If you have multiple Docker repositories enabled, installing or updating without specifying a version in the apt-get install or apt-get update command always installs the highest possible version, which may not be appropriate for your stability needs.

  3. On production systems, you should install a specific version of Docker Engine - Enterprise instead of always using the latest. The following output is truncated.

    $ apt-cache madison docker-ee

docker-ee | 19.03.0~ee-0~ubuntu-xenial | <DOCKER-EE-URL>/ubuntu xenial/stable amd64 Packages

    The contents of the list depend upon which repositories are enabled, and are specific to your version of Ubuntu (indicated by the xenial suffix on the version, in this example). Choose a specific version to install. The second column is the version string. The third column is the repository name, which indicates which repository the package is from and by extension its stability level. To install a specific version, append the version string to the package name and separate them by an equals sign (=).

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

    The Docker daemon starts automatically.

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

    $ sudo docker run hello-world

    This command downloads a test image and runs it in a container. When the container runs, it prints an informational message and exits.

Docker Engine - Enterprise 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 steps.

Upgrade Docker Engine - Enterprise

  1. If upgrading to a new major Docker Engine - Enterprise version (such as when going from Docker 18.03.x to Docker 18.09.x), add the new repository.

  2. Run sudo apt-get update.

  3. Follow the installation instructions, choosing the new version you want to install.

Install from a package

If you cannot use Docker’s repository to install Docker Engine - Enterprise, you can download the .deb files for your release and install them manually. You need to download a new file or set of files each time you want to upgrade Docker Engine - Enterprise.

  1. Go to the Docker Engine - Enterprise repository URL associated with your trial or subscription in your browser. Go to /ubuntu/dists/bionic/pool/stable-<VERSION>/amd64/ and download the .deb file for the Ubuntu release, Docker EE version, and architecture you want to install.

    Note

    Starting with 19.03, you have to download three .deb files. They are docker-ee-cli_<version>.deb, containerd.io_<version>.deb, and docker-ee_<version>.deb.

  2. Install Docker, changing the path below to the path where you downloaded the Docker Engine - Enterprise package.

    $ sudo dpkg -i /path/to/package.deb

    Or, if you downloaded the three .deb files, you must install them in the following order:

    $ sudo dpkg -i /path/to/docker-ee-cli_<version>.deb
$ sudo dpkg -i /path/to/containerd.io_<version>.deb
$ sudo dpkg -i /path/to/docker-ee_<version>.deb

    The Docker daemon starts automatically.

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

    $ sudo docker run hello-world

    This command downloads a test image and runs it in a container. When the container runs, it prints an informational message and exits.

Docker Engine - Enterprise 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 Post-installation steps for Linux to allow non-privileged users to run Docker commands and for other optional configuration steps.

Upgrade Docker Engine - Enterprise

To upgrade Docker Engine - Enterprise, download the newer package file and repeat the installation procedure, pointing to the new file.

Uninstall Docker Engine - Enterprise

  1. Uninstall the Docker Engine - Enterprise package.

    $ sudo apt-get purge docker-ee

  2. Images, containers, volumes, or customized configuration files on your host are not automatically removed. Run the following command to delete all images, containers, and volumes.

    $ sudo rm -rf /var/lib/docker

You must delete any edited configuration files manually.
