If the cluster import process was unsuccessful, follow the steps described below to debug and diagnose the issue. Some common scenarios when import can fail are described below

Failure Scenarios

Scenario 1

Incompatible, older version of Kubernetes

Scenario 2

Insufficient cluster capacity (resources) for the Rafay Operator and the specified blueprint

Scenario 3

Conflicting Ingress Controllers ports i.e. Rafay managed Ingress not disabled on cluster where an Ingress Controller already exists.

Scenario 4

3rd Party product blocking the creation of k8s resources such as namespaces etc

Scenario 5

Imported cluster unable to pull required container images from the specified registry due to configured policies etc

Rafay Namespaces

When you run "kubectl apply..", two namespaces for Rafay will be created on the imported cluster.

  • rafay-system
  • rafay-infra

"rafay-system" Namespace

The "rafay-system" namespace is a critical, monitored namespace. It should contain several pods as listed below. Users can use the following kubectl command to list the pods in this namespace.

kubectl get po -n rafay-system

NAME                                           READY    STATUS    RESTARTS   AGE

"rafay-infra" Namespace

The "rafay-infra" namespace contains the Kubernetes resources for infrastructural components managed by Rafay.

kubectl get po -n rafay-infra
