Secret "hubble-ui-client-certs" not found

[elaurensx]

Hubble-ui deployed through official Helm chart along with all other Cilium components..
ui.enabled: true
ui.standalone: false
hubble.tls.auto.enabled: true
hubble.tls.auto.method: cronJob

kubectl describe cronjob hubble-generate-certs -n kube-system doesn't mention anything related to hubble-ui-client-certs..

Same issue. Hubble UI certs are not generated when using hubble.tls.auto.method: cronJob.

[michaelajr]

Is cronJob certgen meant to be used only when Hubble UI is installed in stand alone mode? And then it is to mount the client-cert that was created?

[michaelajr]

Was able to work around this by setting:

ui:
    standalone:
      enabled: true
      tls:
        certsVolume:
          projected:
            defaultMode: 0400
            sources:
              - secret:
                  name: hubble-relay-client-certs
                  items:
                    - key: tls.crt
                      path: client.crt
                    - key: tls.key
                      path: client.key
                    - key: ca.crt
                      path: hubble-relay-ca.crt

Have not fully tested, just an observation that this will allow hubble ui to start up - and I do see flows in the UI.
