Problems with setting POD ENV: JGROUPS_DISCOVERY_PROPERTIES with namespace+labels

[devopstom-user]

Describe the bug

Hey!

it's either parsing bug or I'm doing something wrong but can't seem to find a way to pass both namespace and labels to select only subset of k8s PODs to form HA cluster. The following cfg:

        - name: JGROUPS_DISCOVERY_PROPERTIES
          value: 'namespace=test-keycloak,labels=app=test-keycloak-blue'

seem gets wrongly parsed i.e. = changes to => for entire thing, and then it obviously fails the HTTP request as well after URL encoding it: JGroups discovery to kubernetes.KUBE_PING with properties {namespace=>test-keycloak,labels=>app=>test-keycloak-blue} (...) WARN [org.jgroups.protocols.kubernetes.KUBE_PING] (ServerService Thread Pool -- 58) failed getting JSON response from Kubernetes Client[masterUrl=https://10.96.0.1:443/api/v1, headers={Authorization=#MASKED:947#}, connectTimeout=5000, readTimeout=30000, operationAttempts=3, operationSleep=1000, streamProvider=org.jgroups.protocols.kubernetes.stream.TokenStreamProvider@7690a9ce] for cluster [ejb], namespace [test-keycloak], labels [app=>test-keycloak-blue]; encountered [java.lang.Exception: 3 attempt(s) with a 1000ms sleep to execute [OpenStream] failed.

Version

v15.0.2

Expected behavior

The parsing should result in: JGroups discovery to kubernetes.KUBE_PING with properties {namespace=>test-keycloak,labels=>app=test-keycloak-blue}

Actual behavior

The parsing results in: JGroups discovery to kubernetes.KUBE_PING with properties {namespace=>test-keycloak,labels=>app=>test-keycloak-blue}

How to Reproduce?

add ENV var onto the pods with namespace + labels:

        - name: JGROUPS_DISCOVERY_PROPERTIES
          value: 'namespace=test-keycloak,labels=app=test-keycloak-blue'

Anything else?

No response

You can pass another env variable like: - name: KUBERNETES_LABELS value: app=test-keycloak-blue
