Minikube: Example of running ingress controller

[sebgoa]

Hi folks,

Is there an example somewhere of how to run the ingress controller in minikube ?

I am thinking about more straightforward docs than https://github.com/kubernetes/contrib/tree/master/ingress/controllers/nginx specific to minikube.

Would be nice to get this out of the box.

Great idea. If anyone manages to get this working before we do, please send a writeup!

[sebgoa]

yeah, I cannot get it to work in a regular setup :(

[dlorenc]

Would you mind attaching what you've tried, so we don't go down the same path :) ?

[sebgoa]

haven't tried on minikube yet. maybe in couple hours...

Thanks to some help from folks in the slack #minikube channel, I was able to piece together the following gist: https://gist.github.com/numbsafari/40396b18822d9d7ab0bb9f0d8f1f4296

I saved that to a local file named kubernetes-ingress.yaml and then created them on my local minikube instance (using xhyve driver) with the following command:

$ kubectl create -f kubernetes-ingress.yaml

For my own flavor of fun, I then installed and configured dnsmasq:

$ brew install dnsmasq
$ echo address=/dev/`minikube ip` > /usr/local/etc/dnsmasq.conf
$ sudo launchctl stop homebrew.mxcl.dnsmasq
$ sudo launchctl start homebrew.mxcl.dnsmasq
$ sudo mkdir -p /etc/resolver/
$ sudo bash -c "echo 'nameserver 127.0.0.1' > /etc/resolver/dev"

And now:

$ 15:33 $ curl -L x.echoheaders.dev/foo
CLIENT VALUES:
client_address=172.17.0.6
command=GET
real path=/foo
query=nil
request_version=1.1
request_uri=http://x.echoheaders.dev:8080/foo

SERVER VALUES:
server_version=nginx: 1.10.0 - lua: 10001

have you tried with a "real" app like a basic ghost deployment ?

[sebgoa]

ok figured it out. you can use your gist, remove the echo header objects and just add this for ghost.

# ghost app
apiVersion: v1
kind: Pod
metadata:
  name: ghost
  labels:
    run: ghost
spec:
  containers:
  - image: ghost
    name: ghost
    ports:
    - containerPort: 2368
      protocol: TCP
---
# ghost service #1
apiVersion: v1
kind: Service
metadata:
  labels:
    run: ghost
  name: ghost
spec:
  ports:
  - port: 2368
    protocol: TCP
    targetPort: 2368
  selector:
    run: ghost
---
# Create the ingress resource
# https://github.com/kubernetes/contrib/blob/master/ingress/controllers/nginx/examples/ingress.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ghost
spec:
  rules:
  - http:
      paths:
      - path: /
        backend:
          serviceName: ghost
          servicePort: 2368

nothing to do with minikube. thanks @numbsafari
