What if you run your code as "serverless" functions, but on your own Kubernetes cluster?
Even compiled languages like Rust and Typescript, without having to worry about the pipelines (not very useful though).
What is the use case? I don't know yet, but it's fun to play with.
Interesting things to note:
- You can use configMaps as libraries to share between pods
First cd into the folder of the language you want to use, then:
Create a namespace, an example secret for our function:
kubectl create namespace servernetes
kubectl create secret generic secret-url --from-literal=SECRET_URL=https://myreallysecretwebhooksomewhere.org/ -n servernetesApply with kubectl:
kubectl apply -f manifest.yaml -n servernetesDevelop:
kubectl delete -f manifest.yaml -n servernetes; kubectl apply -f manifest.yaml -n servernetesStart Port Forward:
kubectl port-forward "svc/servernetes-$(pwd | awk -F'-' '{print $NF}')" 7777:7777 -n servernetes &Stop Port Forward:
kill $(lsof -t -i:7777)Port Forward All:
bash ../port-forward-all.shDeploy All:
bash ../deploy-all.shSend a test request:
curl -X POST -H "Content-Type: application/json" -d '{

python3 benchmark.py 100Cleanup:
kubectl delete namespace servernetes
kill $(lsof -t -i:7777)Some interesting results (keep in mind bad implementation for an API):
$ python3 benchmark.py 500
