Nginx Kubernetes Ingress Installation

We are going to use the Nginx installation manifests based on the Nginx Ingress Controller installation guide. For simplicity - we have already prepared an installation script.

  1. Run the command bellow:
./files/4ingress/ingress_install.sh
source ~/.bashrc

Output

Note: checking out 'v1.11.1'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

HEAD is now at 32745366 Release 1.11.1 (#1514)

  1. Expose the Nginx Ingress Dashboard.
cat << EOF | kubectl apply -f -
apiVersion: v1
kind: Service
metadata:
  name: dashboard-nginx-ingress
  namespace: nginx-ingress
  annotations:
    service.beta.kubernetes.io/azure-dns-label-name: dashboard-$randomnumber

  type: LoadBalancer
  ports:
  - port: 80
    targetPort: 8080
    protocol: TCP
    name: http
  selector:

  1. Wait for the EXTERNAL-IP to have an IP address
kubectl get svc --namespace=nginx-ingress

Output

  1. Get the application and ingress dashboard domain names and save them for later and try to access the sites
printf "For app browse to http://$nginx_ingress\nFor ingress dashboard browse to http://$dashboard_nginx_ingress/dashboard.html\n"
