  • This line was added.
  • This line was removed.
  • Formatting was changed.

The following provides important information related to Usage Engine 3.0.2:

...

  • mzOperator.clusterWide
  • mzOperator.experimental.performPeriodicWorkflowCleanup
  • jmx.remote
  • platform.debug.jmx
  • platform.persistence.*: Please use the persistence.* values instead.
  • ingress-nginx-v4.*: The bundled ingress-nginx helm chart that was installed by setting ingress-nginx-v4.enabled=true has been removed. If you were using this, immediately after upgrading upgrading to 3.0.0, please install the Ingress NGINX controller helm chart on its own in order to secure a smooth as possible upgrade. Example:

    Code Block
    helm install my-ingress ingress-nginx/ingress-nginx --version 4.0.17 -f ingress-nginx-values.yaml

    where ingress-nginx-values.yaml contains the values. As a reference these were the default values used for the bundled ingress-nginx helm chart:

    Code Block
    controller:
      scope:
        enabled: true
      admissionWebhooks:
        enabled: false
      metrics:
        enabled: false
        serviceMonitor:
          enabled: false
      ingressClassResource:
        name: nginx
        enabled: true
        default: false
        controllerValue: "k8s.io/ingress-nginx"
        watchIngressWithoutClass: false
      service:
        targetPorts:
          http: 80
          https: 443
        type: NodePort
      extraArgs:
        v: 1
      containerSecurityContext:
        runAsUser: 101
        allowPrivilegeEscalation: true
    serviceAccount:
      create: false

    If you are on AWS and were using the bundled ingress-nginx (by setting ingress-nginx-v4.enabled=true), make sure to set the aws.ingress.serviceName value to the service name of the separately installed ingress nginx (used to be <your usage engine private edition helm installation name>-ingress-nginx-v4-controller but now it will have a different prefix since it is installed separately).

  • suspend.crontab and suspend.duration: Please use the suspend.from and suspend.until values instead.
  • The default resources for the platform container have been removed. From now on it is an active choice to set resources if needed. The default resources used to be:

    Code Block
    platform:
      resources:
        limits:
          memory: 2350Mi
        requests:
          memory: 256Mi

    By default, this is now just:

    Code Block
    platform:
      resources: {}

  • The default dockerhub image pull secret has been removed. If you are pulling the container images from a private container registry, the image pull secret(s) can be specified via the global.imagePullSecrets values.

...

  • The mzOperator.* values have been moved to operator.*.
  • The operator has been made more event driven and less dependent on frequent periodic synchronizations.
    • As a result the default synchronization period has changed from 30 seconds to 300 seconds (5 minutes).
      Use the operator.syncPeriod value to set a different synchronization period.
    • Also, if you are using your own service account(s) for your ECD(s), specified via the operator.common.ecd value, then you need to make sure that it has permissions to get and patch the pods/status resource.

      Code Block
      languageyml
      titleExample rule specification
      kind: Role
      apiVersion: rbac.authorization.k8s.io/v1
      metadata:
        name: my-ecd-role
      rules:
        - apiGroups: [""]
          resources: ["pods/status"]
          verbs: ["get", "patch"]


  • The default memory limits for the platform JVM has changed. What used to be:

    Code Block
    jvmArgs:
      - XX:MaxDirectMemorySize=4096m
      - XX:MaxMetaspaceSize=256m
      - Xms256m
      - Xmx512m

    Is now:

    Code Block
    jvmArgs:
      - XX:MaxMetaspaceSize=512m
      - Xms256m
      - Xmx2g

Action Required for Rollback from 3.x to 2.x

If you need to perform a helm rollback from a 3.x version to a 2.x version, the existing EC Deployment need to patched after having run the helm rollback command.
