 <1> For `AllNamespaces` install mode usage, specify the `openshift-operators` namespace. Otherwise, specify the relevant single namespace for `SingleNamespace` install mode usage.
 <2> Name of the channel to subscribe to.
 <3> Name of the Operator to subscribe to.
 <4> Name of the catalog source that provides the Operator.
 <5> Namespace of the catalog source. Use `openshift-marketplace` for the default OperatorHub catalog sources.

+<7> The `envFrom` parameter defines a list of sources to populate Environment Variables in the container.
+<8> The `volumes` parameter defines a list of Volumes that must exist on the pod created by OLM.
+<9> The `volumeMounts` parameter defines a list of VolumeMounts that must exist in all containers in the pod created by OLM. If a `volumeMount` references a `volume` that does not exist, OLM fails to deploy the Operator.
