List all the operators installed in an RHOCP4 cluster
Environment
- Red Hat OpenShift Container Platform 4.
Issue
- Some operators are provided during the installation because they are required by RHOCP to work. Furthermore, users can install additional ones. How to list both kind of operators?
Resolution
-
Command to list the operators installed by default in an OpenShift cluster:
$ oc get clusteroperators.config.openshift.io NAME VERSION AVAILABLE PROGRESSING DEGRADED SINCE MESSAGE authentication 4.10.31 True False False 2d4h baremetal 4.10.31 True False False 59d cloud-controller-manager 4.10.31 True False False 59d cloud-credential 4.10.31 True False False 59d cluster-autoscaler 4.10.31 True False False 59d config-operator 4.10.31 True False False 59d console 4.10.31 True False False 2d4h csi-snapshot-controller 4.10.31 True False False 59d dns 4.10.31 True False False 59d etcd 4.10.31 True False False 59d image-registry 4.10.31 True False False 58d ingress 4.10.31 True False False 59d insights 4.10.31 True False False 59d kube-apiserver 4.10.31 True False False 59d kube-controller-manager 4.10.31 True False False 59d kube-scheduler 4.10.31 True False False 59d kube-storage-version-migrator 4.10.31 True False False 58d machine-api 4.10.31 True False False 59d machine-approver 4.10.31 True False False 59d machine-config 4.10.31 True False False 59d marketplace 4.10.31 True False False 59d monitoring 4.10.31 True False False 59d network 4.10.31 True False False 59d node-tuning 4.10.31 True False False 58d openshift-apiserver 4.10.31 True False False 39d openshift-controller-manager 4.10.31 True False False 28d openshift-samples 4.10.31 True False False 58d operator-lifecycle-manager 4.10.31 True False False 59d operator-lifecycle-manager-catalog 4.10.31 True False False 59d operator-lifecycle-manager-packageserver 4.10.31 True False False 59d service-ca 4.10.31 True False False 59d storage 4.10.31 True False False 59d -
Command to show the operators installed by users:
$ oc get subscriptions.operators.coreos.com --all-namespaces NAMESPACE NAME PACKAGE SOURCE CHANNEL nvidia-gpu-operator gpu-operator-certified gpu-operator-certified certified-operators stable rhacs-operator rhacs-operator rhacs-operator redhat-operators latest -
At the time when this is being written there is not any native command available to list all the operators in a cluster, although aliases or scripts can be used to get that.
