Hooks and extra objects
Chart values: preflight, tests, extraObjects.
charts/harthelm/values.yaml at v1.5.0preflight
The preflight Job: a Helm pre-install and pre-upgrade hook and an Argo CD PreSync hook, before the pre-migration dump. It checks what an install needs (Kubernetes version, the CRDs and API groups the values ask for, the Secrets the values name, the database's reachability once it exists, the storage class) and fails the sync with a list of what is missing, so nothing changes on a cluster that cannot run the release.
| Value | Type | Default | Description |
|---|---|---|---|
preflight.enabled | boolean | true | |
preflight.resources.requests.cpu | string or number | "20m" | |
preflight.resources.requests.memory | string or number | "32Mi" | |
preflight.resources.limits.memory | string or number | "128Mi" |
tests
helm test <release>: a probe that NetworkPolicies are enforced, endPort ranges included; core shows the result on the admin Capabilities page and in hart admin doctor. Argo CD has no test phase: there a report-only copy runs as a PostSync hook after every sync; with plain Helm run helm test once after an install or a CNI change.
| Value | Type | Default | Description |
|---|---|---|---|
tests.networkPolicy.enabled | boolean | true | |
tests.resources.requests.cpu | string or number | "10m" | |
tests.resources.requests.memory | string or number | "16Mi" | |
tests.resources.limits.memory | string or number | "64Mi" |
extraObjects
Extra objects rendered with the release (full manifests), for what the chart cannot know, for example a CiliumNetworkPolicy that lets the platform pods reach the API server.
| Value | Type | Default | Description |
|---|---|---|---|
extraObjects | list of object | [] |
