This directory contains the setup instructions for an OpenShift Windows Container Workshop.

* Pre-requisites

This guide assumes you have an existing OpenShift 4.15 cluster running in AWS.

For my purposes I have clusters provisioned via the Red Hat Demo System.

* Cluster setup

Follow the steps below to prepare each cluster in advance of the hackathon.

** Login and verify network

Our first step is to login to the cluster and confirm cluster network details

#+begin_src tmux
oc login --web <api-server>
#+end_src

#+begin_src tmux
# Check cluster cidr
oc get network.operator cluster -o yaml
#+end_src

** Enable hybrid overlay networking

https://docs.openshift.com/container-platform/4.15/networking/ovn_kubernetes_network_provider/configuring-hybrid-networking.html#configuring-hybrid-ovnkubernetes

#+begin_src tmux
# Patch the cluster network to enable hybrid overlay networking
oc patch networks.operator.openshift.io cluster --type=merge \
  -p '{
    "spec":{
      "defaultNetwork":{
        "ovnKubernetesConfig":{
          "hybridOverlayConfig":{
            "hybridClusterNetwork":[
              {
                "cidr": "10.128.0.0/14",
                "hostPrefix": 23
              }
            ]
          }
        }
      }
    }
  }'
