Apologies if this is a trivial question, but is it perhaps possible to somehow generate the Pulumi stack of an existing Kubernetes based infrastructure that was manually created? If not, and I do end up manually coding it in Pulumi, assuming the code matches the infra, when it gets applied would it update the existing non-Pulumi based infrastructure and make it Pulumi managed?
Briefly put, how do I turn an existing infrastructure into a Pulumi managed one?
