To get started with Docker EE on {{ linux-dist-long }}, make sure you
|
|
[meet the prerequisites](#prerequisites), then
|
|
[install Docker](#install-docker-ee).
|
|
|
|
{% elsif section == "ee-url-intro" %}

|
|
|
To install Docker Enterprise Edition (Docker EE), you need to know the Docker EE
|
|
repository URL associated with your trial or subscription. These instructions
|
|
work for Docker EE for {{ linux-dist-long }} and for Docker EE for Linux, which
|
|
includes access to Docker EE for all Linux distributions. To get this
|
|
information:
|
|
|
|
- Go to [https://store.docker.com/my-content](https://store.docker.com/my-content).
|
|
- Each subscription or trial you have access to is listed. Click the **Setup**
|
|
button for **Docker Enterprise Edition for {{ linux-dist-long }}**.
|
|
- 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 EE, see
|
|
[Docker Enterprise Edition](https://www.docker.com/enterprise-edition/){: target="_blank" class="_" }.

{% elsif section == "ways-to-install" %}
|
|
|
|
You can install Docker EE in different ways, depending on your needs:
|
|
|
|
- Most users
|
|
[set up Docker's repositories](#install-using-the-repository) and install
|
|
from them, for ease of installation and upgrade tasks. This is the
|
|
recommended approach.
|
|
|
|
- Some users download the {{ package-format }} package and install it manually
|
|
and manage upgrades completely manually. This is useful in situations such as
|
|
installing Docker on air-gapped systems with no access to the internet.
|
|
|
|
|
|
|
|
{% elsif section == "set-up-yum-repo" %}
|
|
|
|
1. Remove any existing Docker repositories from `/etc/yum.repos.d/`.
|
|
|
|
2. Temporarily store the Docker EE repository URL you noted down in the
|
|
[prerequisites](#prerequisites) in an environment variable.
|
|
This will not persist when the current session ends.
|
|
|
|
```bash
|
|
$ export DOCKERURL='<DOCKER-EE-URL>'
|
|
```
|
|
|
|
3. Store your Docker EE repository URL in a `yum` variable in `/etc/yum/vars/`.
|
|
This command relies on the variable you stored in the previous step.
|
|
|
|
```bash
|
|
$ sudo -E sh -c 'echo "$DOCKERURL/{{ linux-dist-url-slug }}" > /etc/yum/vars/dockerurl'
|
|
```
|
|
|
|
{% if linux-dist == "rhel" %}
|
|
|
|
Store your OS version string in `/etc/yum/vars/dockerosversion`. Most users
|
|
should use `7`, but you can also use the more specific minor version,
|
|
starting from `7.2`.
|
|
|
|
```bash
|
|
$ sudo sh -c 'echo "7" > /etc/yum/vars/dockerosversion'
|
|
```
|
|
|
|
{% endif %}
|
|
|
|
4. Install required packages. `yum-utils` provides the `yum-config-manager`
|
|
utility, and `device-mapper-persistent-data` and `lvm2` are required by the
|
|
`devicemapper` storage driver.
|
|
|
|
```bash
|
|
$ sudo yum install -y yum-utils \
|
|
device-mapper-persistent-data \
|
|
lvm2
|
|
```
|
|
|
|
{% if linux-dist == "rhel" %}
|
|
5. Enable the `extras` RHEL repository. This ensures access to the
|
|
`container-selinux` package which is required by `docker-ee`.
|
|
|
|
```bash
|
|
$ sudo yum-config-manager --enable rhel-7-server-extras-rpms
|
|
```
|
|
|
|
Depending on cloud provider, you may also need to enable another repository.
|
|
|
|
For AWS:
|
|
|
|
```bash
|
|
$ sudo yum-config-manager --enable rhui-REGION-rhel-server-extras
|
|
```
|
|
|
|
> **Note**: `REGION` here is literal, and does *not* represent the region
|
|
> your machine is running in.
|
|
|
|
For Azure:
|
|
|
|
```bash
|
|
$ sudo yum-config-manager --enable rhui-rhel-7-server-rhui-extras-rpms
|
|
```
|
|
{% endif %}
|
|
|
|
6. Use the following command to add the **stable** repository:
|
|
|
|
```bash
|
|
$ sudo -E yum-config-manager \
|
|
--add-repo \
|
|
"$DOCKERURL/{{ linux-dist-url-slug }}/docker-ee.repo"
|
|
```
|
|
|
|
|
|
{% elsif section == "install-using-yum-repo" %}
|
|
|
|
1. Install the latest version of Docker EE, or go to the next step to install a
|
|
specific version.
|
|
|
|
```bash
|
|
$ sudo yum -y install docker-ee
|
|
```
|
|
|
|
If this is the first time you are installing a package from a recently added
|
|
repository, you will be prompted to accept the GPG key, and
|
|
the key's fingerprint will be shown. Verify that the fingerprint matches
|
|
`{{ gpg-fingerprint }}` and if so, accept the key.
|
|
|
|
2. On production systems, you should install a specific version of Docker EE
|
|
instead of always using the latest. List the available versions.
|
|
This example uses the `sort -r` command to sort the results by version
|
|
number, highest to lowest, and is truncated.
|
|
|
|
```bash
|
|
$ sudo yum list docker-ee --showduplicates | sort -r
|
|
|
|
docker-ee.x86_64 {{ site.docker_ee_version }}.ee.2-1.el7.{{ linux-dist }} docker-ee-stable-17.06
|
|
```
|
|
|
|
The contents of the list depend upon which repositories you have enabled,
|
|
and will be specific to your version of {{ linux-dist-long }}
|
|
(indicated by the `.el7` suffix on the version, in this example). Choose a
|
|
specific version to install. The second column is the version string. You
|
|
can use the entire version string, but **you need to include at least to the
|
|
first hyphen**. 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 a hyphen (`-`):
|
|
|
|
> **Note**: The version string is the package name plus the version up to
|
|
> the first hyphen. In the example above, the fully qualified package name
|
|
> is `docker-ee-17.06.1.ee.2`.
|
|
|
|
```bash
|
|
$ sudo yum -y install <FULLY-QUALIFIED-PACKAGE-NAME>
|
|
```
|
|
|
|
Docker is installed but not started. The `docker` group is created, but no
|
|
users are added to the group.
|
|
|
|
{% if linux-dist == "centos" or linux-dist == "rhel" or linux-dist == "oraclelinux" %}
|
|
3. If you need to use `devicemapper`, follow the procedure in the
|
|
[devicemapper storage driver guide](/engine/userguide/storagedriver/device-mapper-driver.md#configure-direct-lvm-mode-for-production){: target="_blank" class="_" }
|
|
**before starting Docker**. For production systems using `devicemapper`,
|
|
you must use `direct-lvm` mode,
|
|
which requires you to prepare the block devices.
|
|
{% endif %}
|
|
|
|
4. Start Docker.
|
|
|
|
```bash
|
|
$ sudo systemctl start docker
|
|
```
|
|
|
|
5. Verify that Docker EE is installed correctly by running the `hello-world`
|
|
image.
|
|
|
|
```bash
|
|
$ 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 EE is installed and running. You need to use `sudo` to run Docker
|
|
commands. Continue to [Linux postinstall](linux-postinstall.md) to allow
|
|
non-privileged users to run Docker commands and for other optional configuration
|
|
steps.
|
|
|
|
|
|
|
|
{% elsif section == "upgrade-using-yum-repo" %}
|
|
|
|
To upgrade Docker EE:
|
|
|
|
1. If upgrading to a new major Docker EE version (such as when going from
|
|
Docker 17.03.x to Docker 17.06.x),
|
|
[add the new repository](#set-up-the-repository){: target="_blank" class="_" }.
|
|
|
|
2. Follow the
|
|
[installation instructions](#install-docker), choosing the new version you
|
|
want to install.
|
|
|
|
|
|
{% elsif section == "install-using-yum-package" %}
|
|
|
|
If you cannot use the official Docker repository to install Docker EE, you can
|
|
download the `.{{ package-format | downcase }}` file for your release and
|
|
install it manually. You will need to download a new file each time you want to
|
|
upgrade Docker EE.
|
|
|
|
{% if linux-dist == "rhel" %}
|
|
1. Enable the `extras` RHEL repository. This ensures access to the
|
|
`container-selinux` package which is required by `docker-ee`.
|
|
|
|
```bash
|
|
$ sudo yum-config-manager --enable rhel-7-server-extras-rpms
|
|
```
|
|
|
|
Alternately, obtain that package manually from Red Hat.
|
|
There is no way to publicly browse this repository.
|
|
{% endif %}
|
|
|
|
{% if linux-dist == "centos" %}
|
|
1. Go to the Docker EE repository URL associated with your
|
|
trial or subscription in your browser. Go to
|
|
`{{ linux-dist-url-slug }}/7/x86_64/stable-{{ site.docker_ee_version }}/Packages` and
|
|
download the `.{{ package-format | downcase }}` file for the Docker version
|
|
you want to install.
|
|
{% endif %}
|
|
{% if linux-dist == "rhel" or linux-dist == "oraclelinux" %}
|
|
1. Go to the Docker EE repository URL associated with your
|
|
trial or subscription in your browser. Go to
|
|
`{{ linux-dist-url-slug }}/`. Choose your {{ linux-dist-long }} version,
|
|
architecture, and Docker version. Download the
|
|
`.{{ package-format | downcase }}` file from the `Packages` directory.
|
|
|
|
{% if linux-dist == "rhel" %}
|
|
> **Note**: If you have trouble with `selinux` using the packages under the
|
|
> `7` directory, try choosing the version-specific directory instead, such
|
|
> as `7.3`.
|
|
|
|
{% endif %}
|
|
{% endif %}
|
|
|
|
2. Install Docker EE, changing the path below to the path where you downloaded
|
|
the Docker package.
|
|
|
|
```bash
|
|
$ sudo yum install /path/to/package.rpm
|
|
```
|
|
|
|
Docker is installed but not started. The `docker` group is created, but no
|
|
users are added to the group.
|
|
|
|
{% if linux-dist == "centos" or linux-dist == "rhel" or linux-dist == "oraclelinux" %}
|
|
3. If you need to use `devicemapper`, follow the procedure in the
|
|
[devicemapper storage driver guide](/engine/userguide/storagedriver/device-mapper-driver.md#configure-direct-lvm-mode-for-production){: target="_blank" class="_" }
|
|
**before starting Docker**. For production systems using `devicemapper`,
|
|
you must use `direct-lvm` mode,
|
|
which requires you to prepare the block devices.
|
|
{% endif %}
|
|
|
|
4. Start Docker.
|
|
|
|
```bash
|
|
$ sudo systemctl start docker
|
|
```
|
|
|
|
5. Verify that Docker EE is installed correctly by running the `hello-world`
|
|
image.
|
|
|
|
```bash
|
|
$ sudo docker run hello-world
|
|
```
|
|
|
|
This command downloads a test image and runs it in a container. When the

|
{% elsif section == "upgrade-using-yum-package" %}
|
|
|
|
To upgrade Docker EE, download the newer package file and repeat the
|
|
[installation procedure](#install-from-a-package), using `yum -y upgrade`
|
|
instead of `yum -y install`, and pointing to the new file.
|
|
|
|
{% elsif section == "yum-uninstall" %}
|
|
|
|
1. Uninstall the Docker EE package:
|
|
|
|
```bash
|
|
$ sudo yum -y remove docker-ee
|
|
```
|
|
|
|
2. Images, containers, volumes, or customized configuration files on your host
|
|
are not automatically removed. To delete all images, containers, and
|
|
volumes:
|
|
|
|
```bash
|
|
$ sudo rm -rf /var/lib/docker
|
|
```
|
|
|
|
3. If desired, remove the `devicemapper` thin pool and reformat the block
|
|
devices that were part of it.
|
|
|
|
You must delete any edited configuration files manually.
