Chapter 6. Updating Logging There are two types of logging updates: minor release updates (5.y.z) and major release updates (5.y). 6.1. Minor release updates If you installed the logging Operators using the Automatic update approval option, your Operators receive minor version updates automatically. You do not need to complete any manual update steps. If you installed the logging Operators using the Manual update approval option, you must manually approve minor version updates. For more information, see Manually approving a pending Operator update . 6.2. Major release updates For major version updates you must complete some manual steps. For major release version compatibility and support information, see OpenShift Operator Life Cycles . 6.3. Upgrading the Red Hat OpenShift Logging Operator to watch all namespaces In logging 5.7 and older versions, the Red Hat OpenShift Logging Operator only watches the openshift-logging namespace. If you want the Red Hat OpenShift Logging Operator to watch all namespaces on your cluster, you must redeploy the Operator. You can complete the following procedure to redeploy the Operator without deleting your logging components. Prerequisites You have installed the OpenShift CLI ( oc ). You have administrator permissions. Procedure Delete the subscription by running the following command: USD oc -n openshift-logging delete subscription <subscription> Delete the Operator group by running the following command: USD oc -n openshift-logging delete operatorgroup <operator_group_name> Delete the cluster service version (CSV) by running the following command: USD oc delete clusterserviceversion cluster-logging.<version> Redeploy the Red Hat OpenShift Logging Operator by following the "Installing Logging" documentation. Verification Check that the targetNamespaces field in the OperatorGroup resource is not present or is set to an empty string. To do this, run the following command and inspect the output: USD oc get operatorgroup <operator_group_name> -o yaml Example output apiVersion: operators.coreos.com/v1 kind: OperatorGroup metadata: name: openshift-logging-f52cn namespace: openshift-logging spec: upgradeStrategy: Default status: namespaces: - "" # ... 6.4. Updating the Red Hat OpenShift Logging Operator To update the Red Hat OpenShift Logging Operator to a new major release version, you must modify the update channel for the Operator subscription. Prerequisites You have installed the Red Hat OpenShift Logging Operator. You have administrator permissions. You have access to the OpenShift Dedicated web console and are viewing the Administrator perspective. Procedure Navigate to Operators Installed Operators . Select the openshift-logging project. Click the Red Hat OpenShift Logging Operator. Click Subscription . In the Subscription details section, click the Update channel link. This link text might be stable or stable-5.y , depending on your current update channel. In the Change Subscription Update Channel window, select the latest major version update channel, stable-5.y , and click Save . Note the cluster-logging.v5.y.z version. Verification Wait for a few seconds, then click Operators Installed Operators . Verify that the Red Hat OpenShift Logging Operator version matches the latest cluster-logging.v5.y.z version. On the Operators Installed Operators page, wait for the Status field to report Succeeded . 6.5. Updating the Loki Operator To update the Loki Operator to a new major release version, you must modify the update channel for the Operator subscription. Prerequisites You have installed the Loki Operator. You have administrator permissions. You have access to the OpenShift Dedicated web console and are viewing the Administrator perspective. Procedure Navigate to Operators Installed Operators . Select the openshift-operators-redhat project. Click the Loki Operator . Click Subscription . In the Subscription details section, click the Update channel link. This link text might be stable or stable-5.y , depending on your current update channel. In the Change Subscription Update Channel window, select the latest major version update channel, stable-5.y , and click Save . Note the loki-operator.v5.y.z version. Verification Wait for a few seconds, then click Operators Installed Operators . Verify that the Loki Operator version matches the latest loki-operator.v5.y.z version. On the Operators Installed Operators page, wait for the Status field to report Succeeded . 6.6. Updating the OpenShift Elasticsearch Operator To update the OpenShift Elasticsearch Operator to the current version, you must modify the subscription. Note The Logging 5.9 release does not contain an updated version of the OpenShift Elasticsearch Operator. If you currently use the OpenShift Elasticsearch Operator released with Logging 5.8, it will continue to work with Logging until the EOL of Logging 5.8. As an alternative to using the OpenShift Elasticsearch Operator to manage the default log storage, you can use the Loki Operator. For more information on the Logging lifecycle dates, see Platform Agnostic Operators . Prerequisites If you are using Elasticsearch as the default log store, and Kibana as the UI, update the OpenShift Elasticsearch Operator before you update the Red Hat OpenShift Logging Operator. Important If you update the Operators in the wrong order, Kibana does not update and the Kibana custom resource (CR) is not created. To fix this issue, delete the Red Hat OpenShift Logging Operator pod. When the Red Hat OpenShift Logging Operator pod redeploys, it creates the Kibana CR and Kibana becomes available again. The Logging status is healthy: All pods have a ready status. The Elasticsearch cluster is healthy. Your Elasticsearch and Kibana data is backed up . You have administrator permissions. You have installed the OpenShift CLI ( oc ) for the verification steps. Procedure In the Red Hat Hybrid Cloud Console, click Operators Installed Operators . Select the openshift-operators-redhat project. Click OpenShift Elasticsearch Operator . Click Subscription Channel . In the Change Subscription Update Channel window, select stable-5.y and click Save . Note the elasticsearch-operator.v5.y.z version. Wait for a few seconds, then click Operators Installed Operators . Verify that the OpenShift Elasticsearch Operator version matches the latest elasticsearch-operator.v5.y.z version. On the Operators Installed Operators page, wait for the Status field to report Succeeded . Verification Verify that all Elasticsearch pods have a Ready status by entering the following command and observing the output: USD oc get pod -n openshift-logging --selector component=elasticsearch Example output NAME READY STATUS RESTARTS AGE elasticsearch-cdm-1pbrl44l-1-55b7546f4c-mshhk 2/2 Running 0 31m elasticsearch-cdm-1pbrl44l-2-5c6d87589f-gx5hk 2/2 Running 0 30m elasticsearch-cdm-1pbrl44l-3-88df5d47-m45jc 2/2 Running 0 29m Verify that the Elasticsearch cluster status is green by entering the following command and observing the output: USD oc exec -n openshift-logging -c elasticsearch elasticsearch-cdm-1pbrl44l-1-55b7546f4c-mshhk -- health Example output { "cluster_name" : "elasticsearch", "status" : "green", } Verify that the Elasticsearch cron jobs are created by entering the following commands and observing the output: USD oc project openshift-logging USD oc get cronjob Example output NAME SCHEDULE SUSPEND ACTIVE LAST SCHEDULE AGE elasticsearch-im-app */15 * * * * False 0 <none> 56s elasticsearch-im-audit */15 * * * * False 0 <none> 56s elasticsearch-im-infra */15 * * * * False 0 <none> 56s Verify that the log store is updated to the correct version and the indices are green by entering the following command and observing the output: USD oc exec -c elasticsearch <any_es_pod_in_the_cluster> -- indices Verify that the output includes the app-00000x , infra-00000x , audit-00000x , .security indices: Example 6.1.
