# OpenShift 4.10+ (Windows) Install
This repository helps automate the install of OpenShift 4.10+
with Kubernetes OVN for use with Windows containers
Note: Running these scripts on a Linux workstation with internet access is assumed
## QuickStart
```
# pull this repo
git clone https://github.com/codekow/demo-ocp-windows.git
cd demo-ocp-windows
# setup vmware roles (optional)
. hacks/vsphere_roles.sh
vsphere_create_roles
# easy install button :)
hacks/install_ocp_win.sh
# run openshift-install
openshift-install create cluster --dir generated/ocp
```
## VMware Notes
Add vSphere folder path to `install-config.yml` at the following level in the yaml
```
platform:
vsphere:
# example folder path
# folder: /${{ datacenter }}/vm/${{ folder path}}
folder: /Central/vm/Sandbox/ocp4.tigerlab.io
vcenter: 10.1.2.3
...
```
Assumption: Two vCenter Accounts
- Admin Account
- Installer Account (w/ roles assigned)
### Admin Account
`hacks/vsphere_roles.sh` is available to help automate the creation of vCenter roles with a vCenter administrator account.
### Installer Account
Assign the following roles to the vCenter account being used to install OpenShift at various levels in vCenter listed below.
### Precreated virtual machine folder in vSphere vCenter
Role Name | Propagate | Entity
--- | --- | ---
openshift-vcenter-level | False | vCenter
ReadOnly | False | Datacenter
openshift-cluster-level | True | Cluster
openshift-datastore-level | False | Datastore
ReadOnly | False | Switch
openshift-portgroup-level | False | Port Group
ReadOnly | True | Virtual Machine folder (Top Level)
openshift-folder-level | True | Virtual Machine folder
In a cascading (nested) folder organization you will need "`Read-only`" permissions
with "`Propagate to children`" from the top folder level.
Example Service Account: `OCPInstaller`
