There are two ways to install and upgrade [Docker Enterprise](https://www.docker.com/enterprise-edition/){: target="_blank" class="_" }
|
|
on {{ linux-dist-long }}:
|
|
|
|
- [YUM repository](#repo-install-and-upgrade): Set up a Docker repository and install Docker Engine - Enterprise from it. This is the recommended approach because installation and upgrades are managed with YUM and easier to do.
|
|
|
|
- [RPM package](#package-install-and-upgrade): Download the {{ package-format }} package, install it manually, and manage upgrades manually. This is useful when installing Docker Engine - Enterprise on air-gapped systems with no access to the internet.

## Prerequisites
|
|
|
|
This section lists what you need to consider before installing Docker Engine -
|
|
Enterprise. Items that require action are explained below.
|
|
|
|
- Use {{ linux-dist-cap }} 64-bit 7.4 and higher on `x86_64`.
|
|
- Use storage driver `overlay2` or `devicemapper` (`direct-lvm` mode in
|
|
production).
|
|
- Find the URL for your Docker Engine - Enterprise repo at [Docker Hub](https://hub.docker.com/my-content){: target="_blank" class="_" }.
|
|
- Uninstall old versions of Docker.
|
|
- Remove old Docker repos from `/etc/yum.repos.d/`.
|
|
|
|
> **Note:**
|
|
> IBM Z (`s390x`) is supported for Docker Engine - Enterprise 17.06.xx only. If
|
|
> you're going to install Docker on an IBM Z system, disable SELinux before
|
|
> installing/upgrading and make sure you're installing Docker Engine -
|
|
> Enterprise 17.06.xx.
|
|
|
|
### Architectures and storage drivers
|
|
|
|
Docker Engine - Enterprise supports {{ linux-dist-long }} 64-bit, versions 7.4
|
|
and higher running on `x86_64`. See [Compatibility Matrix](https://success.docker.com/article/compatibility-matrix){: target="_blank" class="_" }
|
|
for specific details.
|
|
|
|
On {{ linux-dist-long }}, Docker Engine - Enterprise supports storage drivers,
|
|
`overlay2` and `devicemapper`. In Docker Engine - Enterprise 17.06.2-ee-5 and
|
|
higher, `overlay2` is the recommended storage driver. The following limitations
|
|
apply:
|
|
|
|
- [OverlayFS](/storage/storagedriver/overlayfs-driver){: target="_blank" class="_" }:
|
|
If `selinux` is enabled, the `overlay2` storage driver is supported on
|
|
{{ linux-dist-cap }} 7.4 or higher. If `selinux` is disabled, `overlay2` is
|
|
supported on {{ linux-dist-cap }} 7.2 or higher with kernel version 3.10.0-693
|
|
and higher.
|
|
|
|
- [Device Mapper](/storage/storagedriver/device-mapper-driver/){: target="_blank" class="_" }:
|
|
On production systems using `devicemapper`, you must use `direct-lvm` mode,
|
|
which requires one or more dedicated block devices. Fast storage such as
|
|
solid-state media (SSD) is recommended. Do not start Docker until properly
|
|
configured per the [storage guide](/storage/storagedriver/device-mapper-driver/){: target="_blank" class="_" }.
|
|
|
|
### FIPS 140-2 cryptographic module support
|
|
|
|
[Federal Information Processing Standards (FIPS) Publication 140-2](https://csrc.nist.gov/csrc/media/publications/fips/140/2/final/documents/fips1402.pdf)
|
|
is a United States Federal security requirement for cryptographic modules.
|
|
|
|
With Docker Engine - Enterprise Basic license for versions 18.03 and later,
|
|
Docker provides FIPS 140-2 support in RHEL 7.3, 7.4 and 7.5. This includes a
|
|
FIPS supported cryptographic module. If the RHEL implementation already has FIPS
|
|
support enabled, FIPS is also automatically enabled in the Docker engine. If
|
|
FIPS support is not already enabled in your RHEL implementation, visit the
|
|
[Red Hat Product Documentation](https://access.redhat.com/documentation/en-us/)
|
|
for instructions on how to enable it.
|
|
|
|
To verify the FIPS-140-2 module is enabled in the Linux kernel, confirm the file
|
|
`/proc/sys/crypto/fips_enabled` contains `1`.
|
|
|
|
```
|
|
$ cat /proc/sys/crypto/fips_enabled
|
|
1
|
|
```
|
|
|
|
> **Note:**
|
|
> FIPS is only supported in Docker Engine Engine - Enterprise. UCP
|
|
> and DTR currently do not have support for FIPS-140-2.
|
|
|
|
You can override FIPS 140-2 compliance on a system that is not in FIPS 140-2
|
|
mode. Note, this **does not** change FIPS 140-2 mode on the system. To override
|
|
the FIPS 140-2 mode, follow ths steps below.
|
|
|
|
Create a file called `/etc/systemd/system/docker.service.d/fips-module.conf`.
|
|
Add the following:
|
|
|
|
```
|
|
[Service]
|
|
Environment="DOCKER_FIPS=1"
|
|
```
|
|
|
|
Reload the Docker configuration to systemd.
|
|
|
|
`$ sudo systemctl daemon-reload`
|
|
|
|
Restart the Docker service as root.
|
|
|
|
`$ sudo systemctl restart docker`
|
|
|
|
To confirm Docker is running with FIPS-140-2 enabled, run the `docker info`
|
|
command.
|
|
|
|
{% raw %}
|
|
```
|
|
docker info --format {{.SecurityOptions}}
|
|
[name=selinux name=fips]
|
|
```
|
|
{% endraw %}
|
|
|
|
### Disabling FIPS-140-2
|
|
|
|
If the system has the FIPS 140-2 cryptographic module installed on the operating
|
|
system, it is possible to disable FIPS-140-2 compliance.
|
|
|
|
To disable FIPS 140-2 in Docker but not the operating system, set the value
|
|
`DOCKER_FIPS=0` in the `/etc/systemd/system/docker.service.d/fips-module.conf`.
|
|
|
|
Reload the Docker configuration to systemd.
|
|
|
|
`$ sudo systemctl daemon-reload`
|
|
|
|
Restart the Docker service as root.
|
|
|
|
`$ sudo systemctl restart docker`
|
|
|
|
### Find your Docker Engine - Enterprise repo URL
|
|
|
|
To install Docker Enterprise, you will need the URL of the Docker Enterprise repository associated with your trial or subscription:
|
|
|
|
1. Go to [https://hub.docker.com/my-content](https://hub.docker.com/my-content){: target="_blank" class="_" }. All of your subscriptions and trials are listed.
|
|
2. Click the **Setup** button for **Docker Enterprise Edition for {{ linux-dist-long }}**.
|
|
3. Copy the URL from **Copy and paste this URL to download your Edition** and save it for later use.
|
|
|
|
You will use this URL in a later step to create a variable called, `DOCKERURL`.

|
|
|
### Uninstall old Docker versions
|
|
|
|
The Docker Engine - Enterprise package is called `docker-ee`. Older versions
|
|
were called `docker` or `docker-engine`. Uninstall all older versions and
|
|
associated dependencies. The contents of `/var/lib/docker/` are preserved,
|
|
including images, containers, volumes, and networks.
|
|
|
|
```bash
|
|
$ sudo yum remove docker \
|
|
docker-client \
|
|
docker-client-latest \
|
|
docker-common \
|
|
docker-latest \
|
|
docker-latest-logrotate \
|
|
docker-logrotate \
|
|
docker-selinux \
|
|
docker-engine-selinux \
|
|
docker-engine
|
|
```
|
|
|
|
|
|
|
|
## Repo install and upgrade
|
|
|
|
The advantage of using a repository from which to install Docker Engine - Enterprise (or any software) is that it provides a certain level of automation. RPM-based distributions such as {{ linux-dist-long }}, use a tool called YUM that work with your repositories to manage dependencies and provide automatic updates.
|
|
|
|
{% capture selinux-warning %}
|
|
> Disable SELinux before installing Docker Engine - Enterprise 17.06.xx on IBM Z

|
|
>
|
|
> There is currently no support for `selinux` on IBM Z systems. If you attempt
|
|
> to install or upgrade Docker Engine - Enterprise on an IBM Z system with
|
|
> `selinux` enabled, an error is thrown that the `container-selinux` package is
|
|

|
|
> only.
|
|
{:.warning}
|
|
{% endcapture %}
|
|
{{ selinux-warning }}
|
|
|
|
### Set up the repository
|
|
|
|
You only need to set up the repository once, after which you can install Docker Engine - Enterprise _from_ the repo and repeatedly upgrade as necessary.

<div class="tab-content" id="myFirstTab">
|
|
<div id="RHEL_7" class="tab-pane fade in active" markdown="1">
|
|
1. Remove existing Docker repositories from `/etc/yum.repos.d/`:
|
|
|
|
```bash
|
|
$ sudo rm /etc/yum.repos.d/docker*.repo
|
|
```
|
|
|
|
2. Temporarily store the URL (that you [copied above](#find-your-docker-ee-repo-url)) in an environment variable. Replace `<DOCKER-EE-URL>` with your URL in the following command. This variable assignment does not persist when the session ends:
|
|
|
|
```bash
|
|
$ export DOCKERURL="<DOCKER-EE-URL>"
|
|
```
|
|
|
|
3. Store the value of the variable, `DOCKERURL` (from the previous step), in a `yum` variable in `/etc/yum/vars/`:
|
|
|
|
```bash
|
|
$ sudo -E sh -c 'echo "$DOCKERURL/{{ linux-dist-url-slug }}" > /etc/yum/vars/dockerurl'
|
|
```
|
|
|
|
Also, store your OS version string in `/etc/yum/vars/dockerosversion`. Most users should use `7` or `8`, but you can also use the more specific minor version, starting from `7.2`.
|
|
|
|
```bash
|
|
$ sudo sh -c 'echo "7" > /etc/yum/vars/dockerosversion'
|
|
```
|
|
|
|
|
|
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
|
|
```
|
|
|
|
5. Enable the `extras` RHEL repository. This ensures access to the `container-selinux` package required by `docker-ee`.
|
|
|
|
The repository can differ per your architecture and cloud provider, so review the options in this step before running:
|
|
|
|
**For all architectures _except_ IBM Power:**
|
|
|
|
```bash
|
|
$ sudo yum-config-manager --enable rhel-7-server-extras-rpms
|
|
```
|
|
|
|
**For IBM Power only (little endian):**
|
|
|
|
```bash
|
|
$ sudo yum-config-manager --enable extras
|
|
$ sudo subscription-manager repos --enable=rhel-7-for-power-le-extras-rpms
|
|
$ sudo yum makecache fast
|
|
$ sudo yum -y install container-selinux
|
|
```
|
|
|
|
Depending on cloud provider, you may also need to enable another repository:
|
|
|
|
**For AWS** (where `REGION` is a literal, and does _not_ represent the region your machine is running in):
|
|
|
|
```bash
|
|
$ sudo yum-config-manager --enable rhui-REGION-rhel-server-extras
|
|
```
|
|
|
|
**For Azure:**
|
|
|
|
```bash
|
|
$ sudo yum-config-manager --enable rhui-rhel-7-server-rhui-extras-rpms
|
|
```
|
|
|
|
6. Add the Docker Engine - Enterprise **stable** repository:
|
|
|
|
```bash
|
|
$ sudo -E yum-config-manager \
|
|
--add-repo \
|
|
"$DOCKERURL/{{ linux-dist-url-slug }}/docker-ee.repo"
|
|
```
|
|
|
|
</div>
|
|
<div id="RHEL_8" class="tab-pane fade" markdown="1">
|
|
1. Remove existing Docker repositories from `/etc/yum.repos.d/`:
|
|
|
|
```bash
|
|
$ sudo rm /etc/yum.repos.d/docker*.repo
|
|
```
|
|
|
|
2. Temporarily store the URL (that you [copied above](#find-your-docker-ee-repo-url)) in an environment variable. Replace `<DOCKER-EE-URL>` with your URL in the following command. This variable assignment does not persist when the session ends:
|
|
|
|
```bash
|
|
$ export DOCKERURL="<DOCKER-EE-URL>"
|
|
```
|
|
|
|
3. Store the value of the variable, `DOCKERURL` (from the previous step), in a `yum` variable in `/etc/yum/vars/`:
|
|
|
|
```bash
|
|
$ sudo -E sh -c 'echo "$DOCKERURL/{{ linux-dist-url-slug }}" > /etc/yum/vars/dockerurl'
|
|
```
|
|
|
|
Also, store your OS version string in `/etc/yum/vars/dockerosversion`. Most users should use `8`, but you can also use the more specific minor version.
|
|
|
|
```bash
|
|
$ sudo sh -c 'echo "8" > /etc/yum/vars/dockerosversion'
|
|
```
|
|
|
|
|
|
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
|
|
```
|
|
|
|
5. Add the Docker Engine - Enterprise **stable** repository:
|
|
|
|
```bash
|
|
$ sudo -E yum-config-manager \
|
|
--add-repo \
|
|
"$DOCKERURL/{{ linux-dist-url-slug }}/docker-ee.repo"
|
|
```

|
|
</div>
|

### Install from the repository
|
|
|
|
> **Note**: If you need to run Docker Engine - Enterprise 2.0, please see the following instructions:
|
|
> * [18.03](https://docs.docker.com/v18.03/ee/supported-platforms/) - Older Docker Engine - Enterprise Engine only release
|
|
> * [17.06](https://docs.docker.com/v17.06/engine/installation/) - Docker Enterprise Edition 2.0 (Docker Engine,
|
|
> UCP, and DTR).
|
|
|
|
1. Install the latest patch release, or go to the next step to install a specific version:
|
|
|
|
```bash
|
|
$ sudo yum -y install docker-ee docker-ee-cli containerd.io
|
|
```
|
|
|
|
If prompted to accept the GPG key, verify that the fingerprint matches `{{ gpg-fingerprint }}`, and if so, accept it.
|
|
|
|
|
|
2. To install a _specific version_ of Docker Engine - Enterprise (recommended in production), list versions and install:
|
|
|
|
a. List and sort the versions available in your repo. This example sorts 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-18.09
|
|
```
|
|
|
|
The list returned depends on which repositories you enabled, and is specific to your version of {{ linux-dist-long }} (indicated by `.el7` in this example).
|
|
|
|
b. Install a specific version by its fully qualified package name, which is the package name (`docker-ee`) plus the version string (2nd column) starting at the first colon (`:`), up to the first hyphen, separated by a hyphen (`-`). For example, `docker-ee-18.09.1`.
|
|
|
|
```bash
|
|
$ sudo yum -y install docker-ee-<VERSION_STRING> docker-ee-cli-<VERSION_STRING> containerd.io
|
|
```
|
|
|
|
For example, if you want to install the 18.09 version run the following:
|
|
|
|
```bash
|
|
sudo yum-config-manager --enable docker-ee-stable-18.09
|
|
```
|
|
|
|
Docker is installed but not started. The `docker` group is created, but no users are added to the group.
|
|
|
|
3. Start Docker:
|
|
|
|
> If using `devicemapper`, ensure it is properly configured before starting Docker, per the [storage guide](/storage/storagedriver/device-mapper-driver/){: target="_blank" class="_" }.
|
|
|
|
```bash
|
|
$ sudo systemctl start docker
|
|
```
|
|
|
|
4. Verify that Docker Engine - Enterprise is installed correctly by running the `hello-world`
|
|
image. This command downloads a test image, runs it in a container, prints
|
|
an informational message, and exits:
|
|
|
|
```bash
|
|
$ sudo docker run hello-world
|
|
```
|
|
|
|
Docker Engine - Enterprise is installed and running. Use `sudo` to run Docker commands. See
|
|
[Linux postinstall](/install/linux/linux-postinstall.md){: target="_blank" class="_" } to allow
|
|
non-privileged users to run Docker commands.

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.
|
|
|
|
2. Go to the Docker Engine - Enterprise 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 you have trouble with `selinux` using the packages under the `7` directory,
|
|
> try choosing the version-specific directory instead, such as `7.3`.
|
|
|
|
3. Install Docker Enterprise, 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.
|

4. Start Docker:
|
|
|
|
> If using `devicemapper`, ensure it is properly configured before starting Docker, per the [storage guide](/storage/storagedriver/device-mapper-driver/){: target="_blank" class="_" }.
|
|
|
|
```bash
|
|
$ sudo systemctl start docker
|
|

Docker Engine - Enterprise is installed and running. Use `sudo` to run Docker commands. See
|

1. Go to the Docker Engine - Enterprise 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 you have trouble with `selinux` using the packages under the `8` directory,
|
|
> try choosing the version-specific directory instead.
|
|
|
|
2. Install Docker Enterprise, 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.
|
|
|
|
3. Start Docker:
|
|
|
|
> If using `devicemapper`, ensure it is properly configured before starting Docker, per the [storage guide](/storage/storagedriver/device-mapper-driver/){: target="_blank" class="_" }.
|
|
|
|
```bash
|
|
$ sudo systemctl start docker
|
|
```
|
|
|
|
4. Verify that Docker Engine - Enterprise is installed correctly by running the `hello-world`
|
|
image. This command downloads a test image, runs it in a container, prints
|
|
an informational message, and exits:
|
|
|
|
```bash
|
|
$ sudo docker run hello-world
|
|
```
|
|
|
|
Docker Engine - Enterprise is installed and running. Use `sudo` to run Docker commands. See
|
|
[Linux postinstall](/install/linux/linux-postinstall.md){: target="_blank" class="_" } to allow
|
|
non-privileged users to run Docker commands.

### Upgrade with a package
|
|
|
|
1. Download the newer package file.
|
|
|
|
2. Repeat the [installation procedure](#install-with-a-package), using
|
|
`yum -y upgrade` instead of `yum -y install`, and point to the new file.

## Uninstall Docker Engine - Enterprise
|
|
|
|
1. Uninstall the Docker Engine - Enterprise package:
|
|
|
|
```bash
|
|
$ sudo yum -y remove docker-ee
|
|
```
|
|
|
|
2. Delete all images, containers, and volumes (because these are not automatically removed from your host):
|
|
|
|
```bash
|
|
$ sudo rm -rf /var/lib/docker
|
|
```
|
|
|
|
3. Delete other Docker related resources:
|
|
```bash
|
|
$ sudo rm -rf /run/docker
|
|
$ sudo rm -rf /var/run/docker
|
|
$ sudo rm -rf /etc/docker
|
|
```
|
|
|
|
4. 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.
