OpenShift Origin Installation

OpenShift Origin install docker-engine

NOTE: This ONLY works for containerized install method, and does NOT work for default RPM based install method, as openshift origin rpm depedens on docker

Openshift origin is using docker rather than docker-engine.
If you want to use docker-engine latest version in openshift, you need some modifications for ansible scripts.

Mods for ansible to install docker-engine

The ansible script for docker installation is roles/docker/tasks/main.yml. Please make below several changes.

• Get current installed Docker version ` command: “ –installed –qf ‘%{version}’ docker-engine”`

• Get latest available version of Docker

    command: >
      --qf '%{version}' "docker-engine"
  

• Install Docker

    package: name=docker-engine- state=present
  

Manually Add docker-engine yum repository to master(s)/node(s)

sudo yum-config-manager  --add-repo  https://docs.docker.com/engine/installation/linux/repo_files/centos/docker.repo

See docker doc

Specify ansible hosts to use latest docker-engine

vi /etc/ansible/hosts
docker_version="1.13.0"

Then start your ansible installation.
