Deploy a sample web app on a domain name

A brief copy of the GKE static IP tutorial is below.

First, deploy the sample web application manifest which contains the Deployment and a NodePort Service (required by Ingress):

kubectl apply -f https://raw.githubusercontent.com/ahmetb/gke-letsencrypt/master/yaml/sample-app.yaml

Create a static IP called to (will be used in the Ingress):

gcloud compute addresses create helloweb-ip --global

Update your domain name records (at your domain registrar or DNS provider) with this IP address.

gcloud compute addresses describe helloweb-ip --global --format 'value(address)'

Save sample-ingress-tls manifest, which will request a certificate for a domain name from the letsencrypt-prod issuer:

curl -O https://raw.githubusercontent.com/ahmetb/gke-letsencrypt/master/yaml/sample-ingress-tls.yaml

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: helloweb
  annotations:
    kubernetes.io/ingress.global-static-ip-name: helloweb-ip
    certmanager.k8s.io/cluster-issuer: letsencrypt-prod
    certmanager.k8s.io/acme-http01-edit-in-place: "true"
  labels:
    app: hello
spec:
  backend:
    serviceName: helloweb-backend
    servicePort: 8080
  tls:
  - secretName: www-dogs-com-tls
    hosts:
    - www.dogs.com

Modify a few things before deploying this manifest:

• Replace www.dogs.com with your domain name
• Replace dogs-com-tls (will be used to create the TLS Secret) with a name that is suitable
• Replace helloweb with the Ingress name that your website is running on

Then apply this manifest:

kubectl apply -f sample-ingress-tls.yaml

Next: Get a certificate for your domain name →
