Deploying Helm charts & yaml files in the right order, in a declarative way.
- Helm CLI supports only imperative commands, you need to run a bunch of commands like helm repo add, helm repo update, helm install, helm upgrade, etc. it's really hard to manage the lifecycle of the Helm chart in this way.
Deal with secrets in a secure way.
Deploying Kubernetes resources in a unified way, instead of running a bunch of commands like kubectl apply, helm install, kustomize, etc.

Why not ArgoCD or FluxCD?

ArgoCD & FluxCD support only Kubernetes, and it's too heavy for my use case.

Pulumi supports not only Kubernetes but also other cloud providers like Proxmox, Libvirt, AWS, Azure, GCP, etc. It's a unified way to manage the lifecycle of all my infrastructure resources.
