Hello cdk8s (in Python!)

This example application deploys hello-kubernetes using cdk8s.

You can apply this example into your own k8s cluster with these step by step commands:

Import

$ pipenv install
$ cdk8s import --language python

Synthesize the CDK into a k8s template

$ cdk8s synth

Apply the k8s template to your cluster

$ kubectl apply -f dist/hello.k8s.yaml

Demo

After apply step, hello-svc can be reached at localhost:8080:
