simple-svc

kubernetes simple service with envoy sidecar - work in progress

intended to be used with minikube

steps:

• start minikube
• ./build-image.sh to build docker image from src/simple-svc.go and publish to minikube repository
• (cd simple-envoy; ./build-image.sh) to build basic envoy docker image and publish to minikube repository
• install helm on minikube
• helm install helm-chart --set name=service-a --name service-a
• helm install helm-chart --set name=service-b --name service-b
• minikube service --url service-a ; minikube service --url service-b
• assuming the service url if service-a is http://192.168.99.100:30001
  • curl http://192.168.99.100:30001/xxx will call service-a, which will echo back the path "/xxx" and the pod ip
  • curl http://192.168.99.100:30001/service-b/xxx will call service-a, which will extract service-b from the path and call it with "/xxx"
  • curl http://192.168.99.100:30001/service-b-envoy/xxx will call service-a, which will extract service-b-envoy from the path and call it (which actually calls localhost:80 - which is the envoy sidecar port for egress, which is maps to service-b) with "/xxx"
