This is the primary operator for Red Had 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).
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
