Description

Now that we have the ability to create Kubernetes CRDs inside of Terraform configs, it would be useful to convert some Helm charts into Terraform modules.

This issue tracks the following:

Convert top 5 Helm charts into Terraform modules.
Document the process so that contributors can add any other modules.

@daverod24 I opened https://github.com/hashicorp/terraform-provider-kubernetes-alpha/issues/59 so we can track your issue. Going to remove the comment from here to avoid polluting this unrelated issue.

Consul, Vault (I'd really like to deploy HashiCorp products with other HashiCorp products 😅)

Here are a few module examples to try with the v0.3.0 release of the kubernetes-alpha provider. Please note that these are all initial examples and not vetted for production use.

Flux: https://registry.terraform.io/modules/redeux/flux-install/kubernetes/latest
Prometheus-operator: https://registry.terraform.io/modules/aareet/prometheus-operator/kubernetes/latest
Terraform Cloud Operator: https://registry.terraform.io/modules/aareet/terraform-cloud-operator/kubernetes/latest
ArgoCD: https://registry.terraform.io/modules/aareet/argocd/kubernetes/latest
Cert Manager: https://registry.terraform.io/modules/aareet/cert-manager/kubernetes/latest

Please give these a try and share your feedback on any provider issues you encounter by filing bugs with us, thanks!

We will soon follow-up with some instructional material on how to convert your helm charts into a terraform module for use with the kubernetes-alpha provider.

Q: Should we use the new manifest resource for everything or just for custom resources and continue to use the old resources like kubernetes_stateful_set, kubernetes_service etc.?

aareet commented 3 years ago

Hi @Skaronator, we recommend continuing to use the official kubernetes provider for production resources. We are still working to stabilize and mature the kubernetes-alpha provider and hope to have the manifest resource be production capable soon

What exactly are you trying to achieve here? Why not use the helm provider to install helm resources? The process involved in maintaining such modules will likely be stressful. When any update is made to the helm repo/chart, it'll have to be replicated to the terraform module. Eventually, you find out some terraform modules are not to date with what is on the chart because of the stress involved in updating this modules everytime a new change is made in the helm chart.

Kubernetes Provider has it's own use case and in my opinion, rewriting helm charts is not one of them.
