Chapter 6. Administrative tasks
6.1. Starting monitoring
Red Hat OpenShift Local disables cluster monitoring by default to ensure that Red Hat OpenShift Local can run on a typical notebook. Monitoring is responsible for listing your cluster in the Red Hat Hybrid Cloud Console. Follow this procedure to enable monitoring for your cluster.
Prerequisites
-
You must assign additional memory to the Red Hat OpenShift Local instance. At least 14 GiB of memory, a value of
14336, is recommended for core functionality. Increased workloads will require more memory. For more information, see Configuring the instance.
Procedure
Set the
enable-cluster-monitoringconfigurable property totrue:$ crc config set enable-cluster-monitoring true
Start the instance:
$ crc start
WarningCluster monitoring cannot be disabled. To remove monitoring, set the
enable-cluster-monitoringconfigurable property tofalseand delete the existing Red Hat OpenShift Local instance.
6.2. Enabling override Operators
To verify Red Hat OpenShift Local can run on a typical notebook, some resource-heavy services get disabled by default. These services can be enabled by manually removing the desired Operator from the Operator override list.
Prerequisites
-
A running Red Hat OpenShift Local virtual machine and a working
occommand. For more information, see Accessing the OpenShift cluster withoc. -
You must log in through
ocas thekubeadminuser.
Procedure
List unmanaged Operators and note the numeric index for the desired Operator:
On Linux or macOS:
$ oc get clusterversion version -ojsonpath='{range .spec.overrides[*]}{.name}{"\n"}{end}' | nl -v 0On Microsoft Windows using PowerShell:
PS> oc get clusterversion version -ojsonpath='{range .spec.overrides[*]}{.name}{"\n"}{end}' | % {$nl++;"`t$($nl-1) `t $_"};$nl=0
Start the desired Operator using the identified numeric index:
$ oc patch clusterversion/version --type='json' -p '[{"op":"remove", "path":"/spec/overrides/<unmanaged-operator-index>"}]' clusterversion.config.openshift.io/version patched
