Márton Balassi created FLINK-26660:
--------------------------------------
Summary: Specify EventSource when watching multiple namespaces
Key: FLINK-26660
URL: https://issues.apache.org/jira/browse/FLINK-26660
Project: Flink
Issue Type: Sub-task
Components: Kubernetes Operator
Reporter: Márton Balassi
Currently when watching multiple namespaces, for example via the following
command:
{code:java}
kubectl create ns flink-system
kubectl create ns flink-prod
kubectl create ns flink-user
helm install --namespace flink-system --set
"watchNamespaces={flink-prod,flink-user}" flink-operator helm/flink-operator
{code}
The operator itself comes up healthy, but on FlinkDeployment submission and is
unable to reconcile:
{code:java}
# Modify the example to deploy to flink-prod namespace!
kubectl create -f examples/basic.yaml {code}
The operator log show the following:
{code:java}
