Nginx Ingress Controller

This is a simple nginx Ingress controller. Expect it to grow up. See Ingress controller documentation for details on how it works.

Deploying the controller

Deploying the controller is as easy as creating the RC in this directory. Having done so you can test it with the following echoheaders application:

# 3 Services for the 3 endpoints of the Ingress
apiVersion: v1
kind: Service
metadata:
  name: echoheaders-x
  labels:
    app: echoheaders
spec:
  type: NodePort
  ports:
  - port: 80
    nodePort: 30301
    targetPort: 8080
    protocol: TCP
    name: http
  selector:
    app: echoheaders
---
apiVersion: v1
kind: Service
metadata:
  name: echoheaders-default
  labels:
    app: echoheaders
spec:
  type: NodePort
  ports:
  - port: 80
    nodePort: 30302
    targetPort: 8080
    protocol: TCP
    name: http
  selector:
    app: echoheaders
---
apiVersion: v1
kind: Service
metadata:
  name: echoheaders-y
  labels:
    app: echoheaders
spec:
  type: NodePort
  ports:
  - port: 80
    nodePort: 30284
    targetPort: 8080
    protocol: TCP
    name: http
  selector:
    app: echoheaders
---
# A single RC matching all Services
apiVersion: v1
kind: ReplicationController
metadata:
  name: echoheaders
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: echoheaders
    spec:
      containers:
      - name: echoheaders
        image: gcr.io/google_containers/echoserver:1.0
        ports:
        - containerPort: 8080
---
# An Ingress with 2 hosts and 3 endpoints
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: echomap
spec:
  rules:
  - host: foo.bar.com
    http:
      paths:
      - path: /foo
        backend:
          serviceName: echoheaders-x
          servicePort: 80
  - host: bar.baz.com
    http:
      paths:
      - path: /bar
        backend:
          serviceName: echoheaders-y
          servicePort: 80
      - path: /foo
        backend:
          serviceName: echoheaders-x
          servicePort: 80

You should be able to access the Services on the public IP of the node the nginx pod lands on.

Wishlist

  • SSL/TLS
  • Production ready options
  • Dynamic adding backends
  • Varied loadbalancing algorithms

... this list goes on. If you feel you know nginx better than I do, please contribute.
