#knativeserving — Public Fediverse posts

I have to admit I’ve been looking for a problem to solve with #serverless as an excuse to use #KnativeServing or maybe #fission at work.

At work, as part of infra ops we have a handful of webhooks and controllers that could be a function.

I normally talk myself out of it because of the perceived complexity of ingress.

My intangible line of thinking is if that tool is there it would be reached for more often for adhoc Jenkins jobs, crons, potentially webhooks.

Currently trying to get #knative in my homelab going. Stumbling into issues with getting kourier running. Somehow the envoy keep crashing due to now reachable upstreams. Using the knative operator for getting the knative-serving up an running. Does someone else ran into the same issue?

config-wise its pretty easy currently
```
apiVersion: operator.knative.dev/v1beta1
kind: KnativeServing
metadata:
name: knative-serving
spec:
ingress:
kourier:
enabled: true
service-type: "ClusterIP"
```

Played with #Knative on #Kubernetes today, it's pretty nifty

I used `oha` to stress-test a basic health-check service, and it's cool that #KnativeServing can scale from 0 service pods, to 1 pod, and eventually up to 10 pods, all without dropping any requests (the requests are queued if there aren't enough service pods)

It's like having my very own AWS Lambda at home (and honestly easier for me to use than AWS Lambda)

These are the results for running `oha -c 1000 -z 30sec` against my cluster which has 3x Raspberry Pi 4B nodes (all nodes are control-plane nodes but with pod-scheduling enabled):
