Value Statement

OLM introduced a new CustomResourceDefinition called the OperatorCondition allowing operators to communicate conditions to OLM. The Upgradeable “OLM Supported Condition” prevents the existing CSV from being replaced by a newer version of the CSV. When the Upgradeable condition is set to False, OLM will prevent a channel entry in a subscribed package that replaces the operator’s existing CSV from leaving the PendingPhase.

We should leverage the OperatorCondition to prevent OLM from upgrading to a new operator version before the operand (MCE/MCH) has caught up to the desired version.

Definition of Done for Engineering Story Owner (Checklist)

• [x] Operator prevents OLM upgrade while operand upgrade is in progress
• [x] Operator sets default conditions before the pod’s ready probe is set to true
• [x] Once operand upgrade is complete, hold is released so OLM can upgrade operator again
• [x] Operator checks that currentVersion == operator version before giving green light for upgrade
