In this guide, you will learn how to install Docker Enterprise Edition (EE) on AWS. We cover registering for a 30-day Docker EE trial, installing Docker EE Engine on CentOS 7.6, configuring Universal Control Plane (UCP) and Docker Trusted Registry (DTR), and deploying a sample application with both Swarm and Kubernetes on your UCP cluster.

​
Architecture and Prerequisites

All three CentOS 7.6 nodes share a flat network, have required ports open, and run NTP for time sync.

​
1. Register for Docker EE Trial License

  1. Sign in to Docker Hub: https://hub.docker.com
  2. Navigate to Explore → Docker EE → CentOS.
  3. Under Get Docker Enterprise CentOS, click Start One-Month Trial and submit the form.
  4. After activation, go to My Content to view your license.
  5. Click Setup to copy your private Docker EE repository URL.

Ensure your corporate firewall allows access to storebits.docker.com and any other Docker EE endpoints.

​
2. Review Official Installation Documentation

Visit the Mirantis-hosted docs for Docker EE Engine:
  1. Go to https://docs.docker.com → Product Manual → Docker Enterprise.
  2. Select Engine → Linux → CentOS.
You’ll find prerequisites (CentOS 7.1+) and steps to configure the Docker EE Yum repository. Be aware of the Mirantis acquisition announcement effective November 13, 2019.

​
3. Install Docker EE Engine

Perform these steps on ucp-manager (then repeat on ucp-worker and dtr-node):

​
3.1 Verify CentOS Version

[root@ucp-manager ~]# cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core)

​
3.2 Remove Any Older Docker Packages

sudo yum remove -y docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine || true

​
3.3 Configure the Docker EE Repository

  1. Export your private repository URL (replace <your-docker-ee-url>): 
    export DOCKERURL="<your-docker-ee-url>"
  2. Store it in Yum variables: 
    sudo sh -c 'echo "$DOCKERURL/centos" > /etc/yum/vars/dockerurl'
  3. Install prerequisites and add the Docker EE repo: 
    sudo yum install -y yum-utils device-mapper-persistent-data lvm2

sudo -E yum-config-manager \
  --add-repo \
  "$DOCKERURL/centos/docker-ee.repo"

​
3.4 Fix $dockerosversion Placeholder (if needed)

If yum repolist returns a $dockerosversion error, edit /etc/yum.repos.d/docker-ee.repo: 
[docker-ee-stable]
name=Docker EE Stable - $basearch
baseurl=https://storebits.docker.com/ee/centos/sub-<ID>/centos/7/$basearch/stable
...
Replace $dockerosversion with 7 under [docker-ee-stable], then rerun: 
sudo yum repolist
Editing repository files incorrectly can break package resolution. Always back up the .repo file before making changes.

​
3.5 Install Docker EE Packages

sudo yum install -y docker-ee docker-ee-cli containerd.io

​
3.6 Enable and Start Docker

sudo systemctl enable docker
sudo systemctl start docker
sudo systemctl status docker

​
3.7 Verify the Installation

[root@ucp-manager ~]# docker version
Client: Docker Engine - Enterprise
 Version:           19.03.5
 ...
Server: Docker Engine - Enterprise
 Engine:
  Version:          19.03.5
  ...
Congratulations! You have successfully installed Docker EE Engine on CentOS 7.6. Next, you will configure UCP and DTR, add worker nodes, and deploy sample workloads using Swarm and Kubernetes.
