The Helm repo at https://charts.keel.sh has versions 1.0.0–1.0.5, 1.1.0, 1.2.0. 1.0.6 is not published, so the Phase 0 apply failed silently. Bump to 1.2.0 (app version 0.21.1, latest stable).

# Keel — automated Kubernetes Deployment image updates.

# Operation: Keel polls each watched workload's registry hourly (default
|
|
# schedule below; overridable per-workload via keel.sh/pollSchedule).
|
|
# Detection of a new digest under the watched tag triggers a Deployment
|
|
# update (pod template hash bump → rolling restart). Workloads opt in by
|
|
# carrying keel.sh/policy + keel.sh/trigger annotations — those are
|
|
# injected cluster-wide by the inject-keel-annotations ClusterPolicy
|
|
# (stacks/kyverno/modules/kyverno/keel-annotations.tf) on namespaces
|
|
# labeled keel.sh/enrolled=true.
