## Prerequisites
|
|
|
|
This section lists what you need to consider before installing Docker EE. Items
|
|
that require action are explained below.
|
|
|
|
- Use {{ linux-dist-cap }} 64-bit 7.1 and higher on `x86_64`.
|
|
- Use storage driver `overlay2` or `devicemapper` (`direct-lvm` mode in production).
|
|
- Find the URL for your Docker EE 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/`.
|
|
|
|
### Architectures and storage drivers
|
|
|
|
Docker EE supports {{ linux-dist-long }} 64-bit, latest version, running on `x86_64`.
|
|
|
|
On {{ linux-dist-long }}, Docker EE supports storage drivers, `overlay2` and `devicemapper`. In Docker EE 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="_" }.
|
|
|
|
### Find your Docker EE repo URL
|
|
|
|
{% include ee-linux-install-reuse.md section="find-ee-repo-url" %}
|
|
|
|
### Uninstall old Docker versions
|
|
|
|
The Docker EE 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. If you are upgrading from Docker CE to Docker EE, remove the Docker CE package as well.
|
|
|
|
```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
|
|
```
