 * OPTIONAL: In case you applied link:https://docs.openshift.com/container-platform/{ocp4-ver}/networking/network_policy/multitenant-network-policy.html[Configuring multitenant isolation with network policy], you also must apply `allow-from-openshift-apiserver` and `allow-from-workspaces-namespaces` NetworkPolicies to `{prod-namespace}`. 
 The `allow-from-openshift-apiserver` NetworkPolicy allows incoming traffic from `openshift-apiserver` namespace to the `devworkspace-webhook-server` enabling webhooks.
 The `allow-from-workspaces-namespaces` NetworkPolicy allows incoming traffic from each user project to `che-gateway` pod.
