OpenShift cluster-ingress-operator deployment.go IngressController Available Progressing condition rollout complete

💡 Result:

In OpenShift, the IngressController custom resource status is maintained by the cluster-ingress-operator, which manages the lifecycle of ingress controller deployments [1][2]. To determine if an IngressController rollout is complete and healthy, you must check the status conditions provided in the IngressController resource [3][1]. Key Status Conditions The IngressController reports its state through several conditions, primarily Available and Progressing [4][5]. 1. Available: This condition indicates whether the IngressController is ready to serve traffic. It is computed based on multiple factors, including: - The underlying Deployment availability [6]. - The readiness of DNS [6]. - The readiness of the LoadBalancer [6]. The IngressController is considered Available only if all these component conditions are true [6]. 2. Progressing: This condition indicates whether the operator is in the process of rolling out changes [4]. The operator calculates this by monitoring the deployment rolling out status [4][7]. - A roll out is generally considered complete when the Progressing condition is False and the reason is typically AsExpected or similar [8]. - The operator specifically monitors deployment progress, including checking if a new ReplicaSet is available [7]. - Note that certain infrastructure-driven events, such as node reboots or pod evictions (ReplicasStabilizing, PodsStarting), are specifically ignored when computing the Progressing status to avoid false positives during normal cluster maintenance [4][7]. How to Verify Rollout To check the status of an IngressController, use the following oc command: oc describe --namespace=openshift-ingress-operator ingresscontroller/ Look for the Status section, which lists the conditions [1]. You can also verify the underlying deployment status directly: oc rollout status deployment/ -n openshift-ingress This command will watch the deployment until the rollout is complete [9]. The deployment strategy for the IngressController is configured to handle updates gracefully (e.g., using rolling updates with specific maxUnavailable and maxSurge settings) to maintain traffic availability during the transition [10].

Wait for a stable router pod before assigning execPod.

WaitForIngressControllerCondition can return while a single-replica Private ingress controller still has a surge pod. Poll the service-selected pods and require exactly one non-deleting, ready pod with a populated Status.PodIP.

Update the router pod selection after WaitForIngressControllerCondition to poll
the service-selected pods until exactly one non-deleting pod is Ready and has a
populated Status.PodIP, then assign that stable pod to execPod; do not proceed
while a surge pod or unready pod remains.
