I set up a simple 1-node GKE deployment with the default (beta) ingress, created via the GCP console. I would like to set up a Google-managed SSL certificate and HTTPS proxy to the a single GKE node & service hosting HTTP & WebSockets.
There are older methods mentioned out there of using NGINX and Ingress Controller as a load balancer and/or reverse proxy to allow WebSockets and HTTPS, but those options do not integrate with GCP's Load Balancers, which means no Cloud CDN, Cloud NAT or Google-managed SSL certificates. From the documentation, it seems they sorted out the old problems of websockets and https load balancers, but GKE has no information I can find on how to do this.
Is there a way to configure this manually?
The relevant service configuration is:
spec: clusterIP: 10.27.247.83 externalTrafficPolicy: Cluster ports: - nodePort: 30621 port: 80 protocol: TCP targetPort: 3456 selector: app: angmar-wsproxy-test sessionAffinity: None type: LoadBalancer status: loadBalancer: ingress: - ip: 188.8.131.52
The load balancer appears on the GCP Console as a TCP proxy, too, which leaves no option for session affinity, HTTP features like websockets, or Google managed SSL certificates.
