Set up the repository¶

To install MCR using the Mirantis repository you must first set up the repository on the host machine.

Note

MCR only supports x86_64/amd64.

Update the apt package index:
```
sudo apt-get update
```

Install packages that allow apt to use a repository over HTTPS:

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

Store https://repos.mirantis.com in an environment variable:
```
DOCKER_EE_URL="https://repos.mirantis.com"
```
Add a $DOCKER_EE_VERSION variable into your environment.
```
DOCKER_EE_VERSION=<mcr-version>
```

Add Docker’s official GPG key:

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

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:

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

Use the following command to set up the stable repository:

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