Add on: Ingress

This addon adds an NGINX Ingress Controller for MicroK8s. It is enabled by running the command:

  1. microk8s enable ingress

With the Ingress addon enabled, a HTTP/HTTPS ingress rule can be created with an Ingress resource. For example:

  1. apiVersion: networking.k8s.io/v1beta1
  2. kind: Ingress
  3. metadata:
  4.   name: http-ingress
  5. spec:
  6.   rules:
  7.   - http:
  8.       paths:
  9.       - path: /
  10.         backend:
  11.           serviceName: some-service
  12.           servicePort: 80

Additionally, the ingress addon can be configured to expose TCP and UDP services by editing the nginx-ingress-tcp-microk8s-conf and nginx-ingress-udp-microk8s-conf ConfigMaps respectively, and then exposing the port in the Ingress controller.

For example, here a Redis service is exposed via TCP:

  1. ---
  2. apiVersion: v1
  3. kind: ConfigMap
  4. metadata:
  5.   name: nginx-ingress-tcp-microk8s-conf
  6.   namespace: ingress
  7. data:
  8.   6379: "default/redis:6379"
  9. ---
  10. apiVersion: apps/v1
  11. kind: DaemonSet
  12. metadata:
  13.   name: nginx-ingress-microk8s-controller
  14.   namespace: ingress
  15. spec:
  16.   template:
  17.     spec:
  18.       containers:
  19.       - name: nginx-ingress-microk8s
  20.         ports:
  21.         - containerPort: 80
  22.         - containerPort: 443
  23.         - name: proxied-tcp-6379
  24.           containerPort: 6379
  25.           hostPort: 6379
  26.           protocol: TCP
