Chapter 7. Upgrading Service Telemetry Framework to version 1.5

To upgrade Service Telemetry Framework (STF) 1.4 to STF 1.5, you must complete the following steps:

  • Replace AMQ Certificate Manager with Certificate Manager.
  • Remove the ClusterServiceVersion and Subscription objects for Smart Gateway Operator and Service Telemetry Operator in the service-telemetry namespace on your Red Hat OpenShift Container Platform environment.
  • Upgrade Red Hat OpenShift Container Platform from 4.8 to 4.10.
  • Re-enable the operators that you removed.

Prerequisites

  • You have backed up your data. There is an outage during the Red Hat OpenShift Container Platform upgrade. You cannot reconfigure the ServiceTelemetry and SmartGateway objects during the Operators replacement.
  • You have prepared your environment for upgrade from Red Hat OpenShift Container Platform 4.8 to the supported version, 4.10.
  • The Red Hat OpenShift Container Platform cluster is fully-connected. STF does not support disconnected or restricted-network clusters.

7.2. Upgrading Red Hat OpenShift Container Platform to 4.10
링크 복사

Service Telemetry Framework (STF) 1.5 is only compatible with Red Hat OpenShift Container Platform 4.10. For more information about upgrading your Red Hat OpenShift Container Platform from 4.8 to 4.10, see Updating clusters overview.

Prerequisites

  • You removed the STF 1.4 Operators.
  • You removed the AMQ Certificate Manager Operator and Grafana Operator. You must remove the Operators before you upgrade Red Hat OpenShift Container Platform because the Operator APIs are incompatible with 4.10. For more information about preparing your Red Hat OpenShift Container Platform for upgrade from 4.8 to 4.10, see Understanding OpenShift Container Platform updates.

  • Verify the suitability of your Red Hat OpenShift Container Platform upgrade: 

    $ oc adm upgrade
    Copy to Clipboard Toggle word wrap

    You cannot upgrade the cluster if you encounter the following error message: 

    Cluster operator operator-lifecycle-manager should not be upgraded between minor versions: ClusterServiceVersions blocking cluster upgrade: service-telemetry/grafana-operator.v3.10.3 is incompatible with OpenShift minor versions greater than 4.8,openshift-operators/amq7-cert-manager.v1.0.11 is incompatible with OpenShift minor versions greater than 4.8

7.3. Installing the Service Telemetry Framework 1.5 Operators
링크 복사

Install the Service Telemetry Framework (STF) 1.5 Operators and the Certificate Manager for OpenShift Operator on your Red Hat OpenShift Container Platform environment. See Section 1.1, “Support for Service Telemetry Framework” for more information about STF support status and life cycle.

Prerequisites

Procedure

  1. Change to the service-telemetry project: 

    $ oc project service-telemetry
    Copy to Clipboard Toggle word wrap

  2. Create a namespace for the cert-manager Operator: 

    $ oc create -f - <<EOF
apiVersion: project.openshift.io/v1
kind: Project
metadata:
  name: openshift-cert-manager-operator
spec:
  finalizers:
  - kubernetes
EOF
    Copy to Clipboard Toggle word wrap

  3. Create an OperatorGroup for the cert-manager Operator: 

    $ oc create -f - <<EOF
apiVersion: operators.coreos.com/v1
kind: OperatorGroup
metadata:
  name: openshift-cert-manager-operator
  namespace: openshift-cert-manager-operator
spec: {}
EOF
    Copy to Clipboard Toggle word wrap

  4. Subscribe to the cert-manager Operator with the redhat-operators CatalogSource: 

    $ oc create -f - <<EOF
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: openshift-cert-manager-operator
  namespace: openshift-cert-manager-operator
spec:
  channel: tech-preview
  installPlanApproval: Automatic
  name: openshift-cert-manager-operator
  source: redhat-operators
  sourceNamespace: openshift-marketplace
EOF
    Copy to Clipboard Toggle word wrap

  5. Validate your ClusterServiceVersion. Ensure that the phase of cert-manager Operator is Succeeded: 

    $ oc get csv --namespace openshift-cert-manager-operator --selector=operators.coreos.com/openshift-cert-manager-operator.openshift-cert-manager-operator

NAME                            DISPLAY                                       VERSION   REPLACES   PHASE
openshift-cert-manager.v1.7.1   cert-manager Operator for Red Hat OpenShift   1.7.1-1              Succeeded
    Copy to Clipboard Toggle word wrap
  6. Optional: Resubscribe to the Grafana Operator. For more information, see: test Section 5.1.1, “Configuring Grafana to host the dashboard”.

  7. Create the Service Telemetry Operator subscription to manage the STF instances: 

    $ oc create -f - <<EOF
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: service-telemetry-operator
  namespace: service-telemetry
spec:
  channel: stable-1.5
  installPlanApproval: Automatic
  name: service-telemetry-operator
  source: redhat-operators
  sourceNamespace: openshift-marketplace
EOF
    Copy to Clipboard Toggle word wrap

  8. Validate the Service Telemetry Operator and the dependent operators: 

    $ oc get csv --namespace service-telemetry
