      1. deploy logging stack with fluentd collector

      2. create a CLF with:

      apiVersion: logging.openshift.io/v1
      kind: ClusterLogForwarder
      metadata:
        name: instance
        namespace: openshift-logging
      spec:
        outputDefaults:
          elasticsearch:
            enableStructuredContainerLogs: true
            structuredTypeKey: kubernetes.namespace_name
            structuredTypeName: test-name
        pipelines:
        - inputRefs:
          - application
          name: forward
          outputRefs:
          - default
          parse: json

      3. create some pods to generate json format logs, then add annotation to pods, for example:

      oc annotate pod centos-logtest-gbt8m containerType.logging.openshift.io/centos-logtest=container-log-centos-logtest -n test-1

      4. check indices in ES, the index name is app-$project-name, not app-container-log-centos-logtest:

      $ oc exec elasticsearch-cdm-slb4l0jd-1-749984d987-rknr8  -- indices
      Defaulted container "elasticsearch" out of: elasticsearch, proxy

      5. remove all the collector pods and wait for new collector pods to be created, check indices again, then the index app-container-log-centos-logtest can be created:

      $ oc exec elasticsearch-cdm-slb4l0jd-1-749984d987-rknr8  -- indices

    • Logging (Core) - Sprint 218

      When set `enableStructuredContainerLogs: true` in CLF, the container's logs are not sent to separate index if the annotation `containerType.logging.openshift.io/centos-logtest: xxxxxx` is added after the pod is ready.

      Workaround: restarting the collector pods.
