# Keel — automated Kubernetes Deployment image updates.
|
||
|

# Design: docs/plans/2026-05-16-auto-upgrade-apps-design.md

# Plan: docs/plans/2026-05-16-auto-upgrade-apps-plan.md

|
# 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.
