XMLWordPrintable

      Version of components:

      clusterlogging.v5.5.0

      elasticsearch-operator.v5.5.0

      loki-operator.v5.5.0

      Kustomize Version: v4.5.4

      Server Version: 4.11.0-0.nightly-2022-06-25-132614

      Kubernetes Version: v1.24.0+9ddc8b1

      Description of the problem:

      In OCP 4.11 SA account do not have a token assciated with it due to which fetching of token for the SA does not work when forwarding logs to Lokistack using Vector as collector and CLF created without creds secret for Lokistack.

      https://kubernetes.io/docs/concepts/configuration/secret/#service-account-token-secrets

      Steps to reproduce the issue:

      1 Deploy ClusterLogging, Lokistack and Elasticsearch 5.5 operators on OCP 4.11.

      2 Create a LokiStack instance.

      3 Create a ClusterLogging instance.

      4 Create a CLF instance to forward logs to Lokistack instance without pipeline secret.

      apiVersion: logging.openshift.io/v1

      5 Extract and check the vector config. No auth.token is added to the config.

      6 Check that there is no token associated with SA.

      oc get sa logcollector -o yaml

      Additional notes:

      User defined token and ca bundle is working fine with latest bug fixes in ClusterLogging 5.5.
