My idea is to build step by step a complete complex solution.

Before start

• Setup kubernetes with minikube: https://gist.github.com/mrbobbytables/d9e5c7224dbba989cf0b8a30d7a231a4
• To see kubernetes dashboard: minikube dashboard

Step 1

Having an ASP.NET Core service with 3 replicas deployed in kubernetes and load balanced using kubernetes load balancer.

• Deploy the service: kubectl apply -f step1/aspnetcoreservice.yaml
• To get service ip address: kubectl get service aspnetcoreservice, external ip address will not be attributed because we are in local kubernetes.
• To get access to the service: minikube service aspnetcoreservice, minikube will create a tunnel to get access to the service from the host machine.

Step 2

Add an ASP.NET Core GRPC Service and make the first service talk to it using ASP.NET Core hosted services.

• Deploy the service: kubectl apply -f step2/aspnetcoregrpcservice.yaml

Step 3

• Deploy Kafka to kubernetes using instructions in: https://github.com/Yolean/kubernetes-kafka
