## 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`, `s390x`, or `ppc64le` (not ppc64).
- Use storage driver `overlay2` or `devicemapper` (`direct-lvm` mode in production).
- Find the URL for your Docker EE repo at [Docker Store](https://store.docker.com/my-content){: target="_blank" class="_" }.
- Uninstall old versions of Docker.
- Remove old Docker repos from `/etc/yum.repos.d/`.
- Disable SELinux on `s390x` (IBM Z) systems before install/upgrade.
### Architectures and storage drivers
Docker EE supports {{ linux-dist-long }} 64-bit, versions 7.1 and higher (7.1, 7.2, 7.3, 7.4), running on one of the following architectures: `x86_64`, `s390x` (IBM Z), or `ppc64le` (IBM Power, little endian format). To ensure you have `ppc64le` (and not `ppc64`), run the command, `uname -m`.
> Little endian format only
>
> On IBM Power systems, Docker EE only supports little endian format, `ppc64le`, even though {{ linux-dist-cap }} 7 ships both big and little endian versions.
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.
```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 \
docker-ce
```
## Repo install and upgrade
{% include ee-linux-install-reuse.md section="using-yum-repo" %}
{% capture selinux-warning %}
> Disable SELinux before installing Docker EE on IBM Z systems
>
> There is currently no support for `selinux` on IBM Z systems. If you attempt to install or upgrade Docker EE on an IBM Z system with `selinux` enabled, an error is thrown that the `container-selinux` package is not found. Disable `selinux` before installing or upgrading Docker on IBM Z.
