etcd-operator v0.4.5 hardcodes quay.io/coreos/etcd:v3.5.12 and the
v1alpha1 EtcdCluster CRD exposes no version field, so the tenant
control-plane etcd runs 3.5.12. kube-apiserver only enables the
RequestWatchProgress storage feature on etcd >= 3.5.13 / >= 3.4.31, and
Kubernetes >= 1.31 enables ConsistentListFromCache (locked-to-true in
1.35), which depends on it. On etcd 3.5.12 every consistent watch fails
inside the stream with HTTP 500 ("the required storage feature
RequestWatchProgress is disabled"), breaking watch-based clients of
aggregated APIs in modern tenants.
Override the etcd container image through spec.podTemplate.spec, which
the operator strategically merges over its generated pod spec (matched
by container name), pinning a >= 3.5.13 patch release. This restores
consistent watches without waiting on the etcd-operator v1alpha2
migration.
