= Installing the Node Observability Operator using the CLI

You can install the Node Observability Operator by using the OpenShift CLI (oc).

.Prerequisites

* You have installed the OpenShift CLI (oc).
* You have access to the cluster with `cluster-admin` privileges.

.Procedure

. Confirm that the Node Observability Operator is available by running the following command:
+
[source,terminal]
----
$ oc get packagemanifests -n openshift-marketplace node-observability-operator
----

+
.Example output
[source,terminal]
----
NAME                            CATALOG                AGE
node-observability-operator     Red Hat Operators      9h
----

. Create the `node-observability-operator` namespace by running the following command:
+
[source,terminal]
----
$ oc new-project node-observability-operator
----

. Create an `OperatorGroup` object YAML file:
+
[source,yaml]
----
cat <<EOF | oc apply -f -
apiVersion: operators.coreos.com/v1
kind: OperatorGroup
metadata:
  name: node-observability-operator
  namespace: node-observability-operator
spec:
  targetNamespaces: []
EOF
----

. Create a `Subscription` object YAML file to subscribe a namespace to an Operator:
+
[source,yaml]
----
cat <<EOF | oc apply -f -
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: node-observability-operator
  namespace: node-observability-operator
spec:
  channel: alpha
  name: node-observability-operator
  source: redhat-operators
  sourceNamespace: openshift-marketplace
EOF
----

.Verification

. View the install plan name by running the following command:
+
[source,terminal]
----
$ oc -n node-observability-operator get sub node-observability-operator -o yaml | yq '.status.installplan.name'
----

+
.Example output
[source,terminal]
----
install-dt54w
----

. Verify the install plan status by running the following command:
+
[source,terminal]
----
$ oc -n node-observability-operator get ip <install_plan_name> -o yaml | yq '.status.phase'
----
+
`<install_plan_name>` is the install plan name that you obtained from the output of the previous command.

+
.Example output
[source,terminal]
----

. Verify that the Node Observability Operator is up and running:
+
[source,terminal]
----
$ oc get deploy -n node-observability-operator
----
