Example k8 setup for enabling access to QA.tech

Setup

Install minicube

This is only needed for local testing of this setup, otherwie you'll use your real kubernetes cluster.

https://minikube.sigs.k8s.io/docs/start/?

To install the latest minikube stable release on ARM64 macOS using binary download:

curl -LO https://github.com/kubernetes/minikube/releases/latest/download/minikube-darwin-arm64
sudo install minikube-darwin-arm64 /usr/local/bin/minikube

And start the service

minikube start

Build and run the cluster

SKIP THIS IF YOU ALREADY HAVE A CLUSTER*

eval $(minikube docker-env)
docker build -t example-webapp ./example-webapp

And apply the k8 config:

kubectl apply -f deployment.yaml
kubectl apply -f service.yaml

Then get the URL:

minikube service example-service

This should expose a URL on a random Port, and when accessed it should respond with;

Hello from inside the kubernetes cluster!

Add Ngrok

This can be done in this example cluster, or in your own k8 cluster!

First, sign up at https://ngrok.com, then get your authtoken.

Then create a k8 secret

kubectl create secret generic ngrok-secret \
 --from-literal=authtoken=<YOUR_NGROK_AUTHTOKEN>

And apply the ngrok configuration:

kubectl apply -f ngrok-deployment.yaml

Then go to: https://dashboard.ngrok.com/endpoints

And you'll find the publicly accessible URL to get inside the cluster

When you go to that url, which should be like https://c19c-94-254-106-50.ngrok-free.app it should display:

Hello from inside the kubernetes cluster!

Point your QA.tech account to this url to test
