How to enable Jaeger operator to look for all Namespaces in K8s

[PrateekKhatri]

Hi Team,

How we can enable jaeger to look all namespaces. As per the documentation I have provided WATCH_NAMESPACE as null, but this is not working. can you please help how we can setup Jaeger to look for all namespaces .

By default it is only looking for the services available in "observability" namespaces,

Note: I have downloaded the jaeger-operator.yaml file and updated WATCH_NAMESPACE to ""
Steps:

helm upgrade  --install cert-manager jetstack/cert-manager --namespace cert-manager --create-namespace --version v1.11.0  --set installCRDs=true --set webhook.hostNetwork=true --set webhook.securePort=10260
kubectl create namespace observability;
kubectl create -f https://github.com/jaegertracing/jaeger-operator/releases/download/v1.41.0/jaeger-operator.yaml -n observability
