haConfigured

HAConfigured is true once the operator has confirmed both 3/3 apiserver replicas AND 3/3 deployed-etcd replicas are Ready for the first time. Etcd readiness is required because in the OSS deployed-etcd path etcd runs in its own StatefulSet — quorum loss with healthy apiserver pods would block writes, so HA is not “operationally ready” until both tiers report 3/3.

boolean

Example

true

haEnabledAt

HAEnabledAt is the moment HAConfigured first became true and acts as the billing anchor. Stamped once, never updated, never cleared (v1 has no HA->single transition).

string

Example

2026-05-25T14:32:11Z

haEtcdReplicasDesired

HAEtcdReplicasDesired is the target HA etcd replica count (3 when HA is enabled, 0 otherwise).

integer

Example

haEtcdReplicasReady

HAEtcdReplicasReady is the count of deployed-etcd replicas currently Ready. Exposed separately from HAReplicasReady because in the OSS deployed-etcd path the etcd StatefulSet is independent of the apiserver StatefulSet, and etcd quorum loss with healthy CP can leave the cluster unable to serve writes.

integer

Example

haPhase

HAPhase is the consumer-friendly HA rollup. One of pending, ha-healthy, ha-degraded, ha-unavailable. Empty for non-HA clusters.

string

Example

ha-healthy

haReplicasDesired

HAReplicasDesired is the target HA replica count (3 when HA is enabled, 0 otherwise).

integer

Example

haReplicasReady

HAReplicasReady is the count of HA control-plane (apiserver) replicas currently Ready.

integer

Example

kubernetesVersion

warnings

Warnings is an array of structured advisory messages. Always present (empty array when none). Populated today only by CREATE when a non-blocking advisory applies (e.g. HA_K8S_VERSION_RETIRING when HA is enabled on the oldest supported k8s minor). Each entry shares the same shape as a structured error envelope.
