Windows Nodes in OpenShift
This current is tested on Vmware, with two machines, one running OpenShift 3.9 on RHEL 7.5. A full openshift subscription is required.
The Windows Node is Windows Server Core 1709. The Windows node requires it to be enabled for Ansible. bin/winansible.ps1 set's up the windows node for ansible.
How to Use:
##Repos for Openshift Windows:
Supported http:/github.com/glennswest/openshift-windows Upstream: http://github.com/glennswest/hybrid
Requirements:
- Linux node with host name set, and static ip, and a proper search domain
- Windows node with a hostname set, and dhcp that returns same ip all the time, matching hostname.
- The windows node must have the correct host name, make sure you rename it.
Overview:
- Install two nodes, one with RHEL 7.5 and one with Windows 1703.
- Setup DNS for both nodes, and search domain so the hosts can be found by both there short name, and there fully qualified name.
- Make sure the windows node can use DHCP to find its IP address.
- Make sure the Mac address is unique for the windows node in the first 5 bytes.
- Login to root, and install git
- git clone repo
- cd repo (Either hybrid or opepnshift-windows)
- Run allinone.sh
Important Note: The Windows Node must run on a physical box, or a environment that supports nested virt, with passthru configured on the VM.
