06/02/2021, 12:18 PMHi Everyone, I am starting a new project where I basically need to deploy the “equivalent” of a bunch of REST (micro-) services, one or two databases an ingress-controller and kafka onto my k3s kubernetes cluster. Because I can choose to use the technology I want, I have decided to explore what it means to go “serverless”. Additionally, I want to use Pulumi as much as possible. I am a developer by trade, but had an active “devops”-role for over 5 years, with 24/7 on-call and all the shiny stuff. I basically want to accomplish what is shown in this tutorial https://www.pulumi.com/serverless/. Before I start, is this currently possible using Pulumi and a local k3s cluster?

06/02/2021, 12:41 PMServerless is a bit of a misnomer, since there is still some infrastructure needed to run your code, but it's invisible to you. AWS, Azure and GCP have their own managed solutions to achieve that. For a local Kubernetes cluster you do have to worry and manage it yourself.
There are some solutions to have the same serverless computational capabilities on Kubernetes, but I don't think any of them are official, thus no Pulumi support.

06/02/2021, 12:49 PMThank you @ambitious-father-68746, by “exploring serverless” I want to learn and understand for myself in how far I can shield or abstract the infrastructure away from my role as a developer. It is clear, that there is always infrastructure involved and in the end, everything runs on bare-metal. Due to our clients-nature, it is not possible to use any public clouds. I have to stay in a local environment and was hoping to find and use the same level of abstraction.

If Pulumi handles Kubernetes objects OK, then it should be possible to achieve what you want.

06/02/2021, 1:04 PMThanks for the hint with kubeless, I will do some research on it. But basically, I would write my own abstractions using Pulumi in case I stay with k3s by using the Kubernetes-plugin and so on. Is my understanding correct?

06/02/2021, 1:34 PMI've done a little experiment in wrapping a terraform provider for kind:
https://github.com/pawelprazak/pulumi-kind/
just an experiment right now so no packaged published
but I've also used pulumi with regular kind
super simple to use
kind create cluster --config kind.config.yamlwith `kind.config.yaml`:
kind: Cluster
apiVersion: <http://kind.x-k8s.io/v1alpha4|kind.x-k8s.io/v1alpha4>
nodes:
- role: control-plane
- role: worker
- role: workerthen just point the provider to it:
const kindContext = "kind-kind"
const kindProvider = new k8s.Provider(kindContext, {
context: kindContext
})and use normally:
const ns = new k8s.core.v1.Namespace(
nsName,
{
metadata: {
name: nsName,
labels: {
name: nsName,
app: appName
}
}
},
{ provider: kindProvider },
)btw. if there are any ts/js devs here and want to drop a PR or issue in my pulimi-kind repo on how to publish to npm, then it would be appreciated (I'm new to node)
