Create service

Create a service of nginx via following steps:

# kubectl run my-nginx --image=nginx --replicas=2 --port=80
# kubectl expose deployment my-nginx --port=8080 --target-port=80 --external-ip=x.x.x.168  

Verify the service via:

kubectl get svc | grep my-nginx
my-nginx                             ClusterIP      172.20.236.170   10.15.205.200   8080/TCP                     3h

nginx-ingress

Use helm for installing nginx-ingress

# helm fetch stable/nginx-ingress
# tar xzvf nginx-ingress-0.8.23.tgz
# cd nginx-ingress

Made modifications to following items:

controller:

//........

	hostNetwork: true

Because in our environment we have to use hostNetwork for a real ip address mapping.

expose to nginx

Define an yaml via:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: dashboard-kibana-ingress
  namespace: default
spec:
  rules:
  - host: ubuntu.xxxxx.com
    http:
      paths:
      - backend:
          serviceName: my-nginx
          servicePort: 8080

Visit your ubuntu.xxxxx.com, you will get the nginx service webpage.

Config examples

For monocular, do following:

# vim custom-domains.yaml
ingress:
  hosts:
  - monocular.xxxxxx.com
# helm install --name=gou -f custom-domains.yaml .

Now adding monocular.xxxxxx.com into your /etc/hosts file, you could directly access monocular UI using domain name.

For wordpress:

# vim values.yaml
ingress:
  ## Set to true to enable ingress record generation
  enabled: true

  ## The list of hostnames to be covered with this ingress record.
  ## Most likely this will be just one host, but in the event more hosts are needed, this is an array
  hosts:
  - name: wordpress.xxxxxx.com

The same as before, you could use wordpress.xxxxxx.com for accessing wordpress.
