Kubernetes Load Balancer Terminating SSL to Reverse Proxy Ingress DigitalOcean - ssl

Question

I had my original infrastructure built around this tutorial. https://www.digitalocean.com/community/tutorials/how-to-set-up-an-nginx-ingress-with-cert-manager-on-digitalocean-kubernetes.
Now I am trying to migrate to managing my own cert and terminating SSL at the load balancer.
With my YAML updates, the load balancer in DigitalOcean shows that all nodes are unhealthy and I the URL response with "503 Service Unavailable
No server is available to handle this request." However, the endpoint shows a secure HTTPS connection. What am I doing wrong?
My new non-functional YAML definitions below.
LoadBalancer
apiVersion: v1
kind: Service
metadata:
name: ingress-nginx
namespace: ingress-nginx
annotations:
service.beta.kubernetes.io/do-loadbalancer-redirect-http-to-https: "true"

Answer 1

I reached out to DigitalOcean support (which is incredible). My issue was I didn't create the ingress-nginx pod. These are the two steps, as listed in the tutorial, that I missed.
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/nginx-0.26.1/deploy/static/mandatory.yaml
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/nginx-0.26.1/deploy/static/provider/cloud-generic.yaml.
My actual YAML definitions were correct.

The best way is just using Digital Ocean Marketplace (https://marketplace.digitalocean.com/apps/nginx-ingress-controller).
Installing it manually will cause a lot of issues due do outdated yml files.
