kubernetes-auto-ingress

Description

Dynamically create an ingress for a service which specifies "autoingress: true" label, for associated namespace of the service.

Use TLS/SSL and backend is / by default.

Works with nginx-ingress-controller.

How to use it

Require nginx-ingress-controller running.

Below describes how to run auto-ingress with your secret for domain example.com

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout tls.key -out tls.crt -subj "/CN=*.example.com"
kubectl create secret tls secret --key tls.key --cert tls.crt
kubectl create -f hack/deployment.yaml

If you want to use it outside of the cluster, provide the kubeconfig with config file:

./kubernetes-auto-ingress -kubeconfig=./config

Then, for every services you want to be ingressed need to put label auto-ingress/enabled: enabled.

Service which is already ingressed can be un-ingressed by setting auto-ingress/enabled: disabled.

apiVersion: v1
kind: Service
metadata:
  name: myapp-service
  labels:
    app: myapp
    auto-ingress/enabled: 'enabled'
spec:
  type: LoadBalancer
  ports:
  - name: http
    port: 80
    targetPort: http
  selector:
    app: myapp

The ingress for this myapp-service will have the same name myapp-service. The servername to access this service would be myapp-service.example.com.
