The OCS Meta Operator

This is the primary operator for Red Hat OpenShift Container Storage (OCS). It is a "meta" operator, meaning it serves to facilitate the other operators in OCS by performing administrative tasks outside their scope as well as watching and configuring their CustomResources (CRs).

Build

The operator is based on the Operator SDK. In order to build the operator, you first need to install the SDK. Instructions are here.

Once the SDK is installed, the operator can be built via:

$ dep ensure --vendor-only

$ operator-sdk build quay.io/openshift/ocs-operator

Initial Data

When the operator starts, it will create a single OCSInitialization resource. That will cause various initial data to be created, including default StorageClasses.

The OCSInitialization resource is a singleton. If the operator sees one that it did not create, it will write an error message to its status explaining that it is being ignored.

Modifying Initial Data

You may modify or delete any of the operator's initial data. To reset and restore that data to its initial state, delete the OCSInitialization resource. It will be recreated, and all associated resources will be either recreated or restored to their original state.
