Do I need this play?

If you want just to give a try to openshift - definitely no. Check below why

Instead, to try

1) oc cluster up

This is included in OpenShift Origin 3.3+ and Red Hat OpenShift Container Platform 3.3+, which allows you to create a Red Hat OpenShift Container Platform environment in a containerized environment. It’s actually creating a containerized platform in a container. It has a lot of flexibility and runs on Windows, Linux, and macOS.

$ oc cluster up --use-existing-config \
               --host-data-dir=/usr/data \
               --metrics=true \
               --image=registry.access.redhat.com/openshift3/ose \
               --version=latest

2) minishift

Minishift is gaining a lot of traction and popularity within the community. It doesn't matter if you're running on Windows, Linux, or Mac. This tool runs OpenShift locally using a single node OpenShift cluster in a virtual machine using a driver, such as kvm, xhyve, or Hyper-V. Many people find value with Minishift, as it provides parameters for customizing settings such as disk size, CPU, and memory.

$ minishift start --cpus=2 --disk-size=20g --memory=2048

or should I ?

If you want to check openshift ansible play https://github.com/openshift/openshift-ansible in "wild zoo" - probably, yes.

BUT, please note, that - 3.11 is latest release for V3. There will be no 3.12

Openshift V4 will be installed with new concept called installer, check https://github.com/openshift/installer/blob/master/docs/user/overview.md#installer-overview

Thus it will not be in scope of this repo anyway.

Ok, you were warned.

Expectations

• Host with 16GB+ memory
• Oracle VirtualBox on host
• Vagrant 2+ on host
• Vagrant plugins vagrant-hostmanager, vagrant-vbguest

vagrant plugin  install vagrant-vbguest
vagrant plugin  install vagrant-hostsupdater

OKD

OKD in operation - 3.11

• OKD v3.11 (default)

previous might work

See Vagrantfile L19

OPENSHIFT_RELEASE = "3.11"
OPENSHIFT_ANSIBLE_BRANCH = "release-#{OPENSHIFT_RELEASE}"

vagrant up

Vagrant spins-up 3 VMs in NETWORK_BASE subnet.

VM Node	Private IP	Roles
master	#{NETWORK_BASE}.101	node, master, etcd
node01	#{NETWORK_BASE}.102	node
node02	#{NETWORK_BASE}.103	node

vagrant up
vagrant provision --provision-with master-key,node01-key,node02-key
vagrant ssh master \
      -c 'ansible-playbook /home/vagrant/openshift-ansible/playbooks/prerequisites.yml &&
          ansible-playbook /home/vagrant/openshift-ansible/playbooks/deploy_cluster.yml'

alternatively,

$ ./okd-setup.sh

OpenShift Web Console

should be available at https://master.openshift.local:8443/ The default login account is admin/admin

(default login is configured in ansible-hosts L27)

openshift_master_htpasswd_users={'admin': '$apr1$ZZPMRUz8$/uqRbAFgpDjm0cirIS6S11'}
