Auto suspend a Kustomization once reconciled?

[ntx-ben]

I'm looking into how I could suspend automatically a Kustomization once it has been successfully reconciled (i.e. a Kustomization would reconcile a Kubernetes Job, and I want that to happen only once).

I've looked into the PostBuild hook to set the suspend field, but I don't think I can use that. Any ideas?

Thanks

The suggestion is, I think, to patch the Kustomization as though it is a "pre-existing resource" like this:

For Kubernetes Jobs there is no need to suspend the Flux Kustomization, Flux performs a dry-run and only applies things that change, in case of a Job it will not run it again, unless you change it in Git and you set Kustomization.spec.force to true. See here how Flux handles Kubernetes Jobs: https://fluxcd.io/docs/use-cases/running-jobs/

What I've noticed is that since my Job has a TTL, once it is removed, Flux will apply it again, and so on forever.

So for now I've removed the TTL and it is working as expected.

Yeap we should add this to docs, Jobs with TTL are not supported.
