Hands-On Microservices with Kubernetes

Adding ingress

On Minikube, you must enable the ingress add-on:

$ minikube addons enable ingress    ingress was successfully enabled

On other Kubernetes clusters, you may want to install your own favorite ingress controller (such as Contour, Traefik, or Ambassador).

apiVersion: extensions/v1beta1 kind: Ingress metadata: name: api-gateway annotations: nginx.ingress.kubernetes.io/rewrite-target: / spec: rules: - host: delinkcio.us http: paths: - path: /* backend: serviceName: api-gateway servicePort: ...
