When you install OpenShift Data Foundation from the Operator Hub, the following four separate Deployments are created:
-
odf-operator: Defines theodf-operatorPod -
ocs-operator: Defines theocs-operatorPod which runs processes forocs-operatorand itsmetrics-exporterin the same container. -
rook-ceph-operator: Defines therook-ceph-operatorPod. -
mcg-operator: Defines themcg-operatorPod.
These operators run independently and interact with each other by creating customer resources (CRs) watched by the other operators. The ocs-operator is primarily responsible for creating the CRs to configure Ceph storage and Multicloud Object Gateway. The mcg-operator sometimes creates Ceph volumes for use by its components.
