We may need to adopt helm install command to make this available 🤔

Ingress NGINX Controller uses Helm hooks to update Admission Webhooks. https://artifacthub.io/packages/helm/ingress-nginx/ingress-nginx#how-the-chart-configures-the-hooks

I would like to see Helm hook support in PipeCD.

Hi @daichi-sato-xa, we currently support CUSTOM_SYNC stage, which we can use a kind of helm install command there. So basically, I guess we can use helm hook with PipeCD. Only one point that is remained, which is we can not perform progressive delivery in case of using CUSTOM_SYNC. Would like to have your idea on how do we support helm hook https://pipecd.dev/docs-v0.45.x/user-guide/managing-application/customizing-deployment/custom-sync/

Hi @khanhtc1202 , Sorry for the delay in replying.

It seems that Argo CD handles this by mapping Helm hook annotations to Argo CD's own hook annotations. https://argo-cd.readthedocs.io/en/stable/user-guide/helm/#helm-hooks

For example, how about PipeCD also mapping Helm's hook annotations to PipeCD's own annotations and executing them in sequence like a Deployment chain?
