​

3.2 Remove Any Older Docker Packages

sudo yum remove -y docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \

                  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)

[docker-ee-stable]
