How to run Job before application deploy

[h3poteto]

In my case, I want to run a Job before flux2 apply deployment, because I have to execute DB migration in deploy. For example rails db:migrate .
Does flux2 support such a function? I hope flux2 can easily control the apply timing of each resources.

We have no support for pre/post deploy hooks as we don't plan to recreate Helm. You can use an init container inside your app deployment and run the migration that way.

Thank you for your quick response.
I see, I've thought about init container, but pre/post deploy hooks are more smarter.

Do you have any plans to support this function?

[stefanprodan]

We already support pre/post hooks when you package your app with Helm and deploy it with HelmReleases, by default helm-controller runs the hooks on install and upgrade.

Is the feature documented? I can't find it.

I see, I understand, the feature is provided by helm. So I can't use it when I use Kustomization.
