Helm Hooks vs. Argo CD Hooks
Helm charts can ship their own lifecycle hooks (pre-install, post-install, pre-upgrade, and so on) to run Jobs, load a ConfigMap, or sequence resources during a release. If your Application source is a Helm chart that uses these hooks, you need to know 3 things:
- Which hooks Argo CD honors.
- How it translates them into its own hook model.
- What happens when a chart's Helm hooks collide with native Argo CD hooks on the same Application.
When Argo CD renders a chart and finds a helm.sh/hook annotation, it maps that hook to one of its own hook phases:
| Helm hook | Argo CD hook phase |
|---|---|
helm.sh/hook: pre-install | PreSync |
helm.sh/hook: pre-upgrade | PreSync |
helm.sh/hook: pre-delete | PreDelete |
helm.sh/hook: post-install | PostSync |
helm.sh/hook: post-upgrade | PostSync |
helm.sh/hook: post-delete | PostDelete |
