Deploy
Create an nginx controller which would be used as load balancer by the ingress
helm install --name ingestion-ingress stable/nginx-ingress --set rbac.create=true
kubectl apply -f app-httpsdeploy.yaml
Now we need to access the app using the same domain name for which we have installed the certificate
Note: The IP it needs to resolve is the IP of the nginx controller which we can found by doing kubectl get services or one can use /etc/hosts to locally resolve the IP
curl -v -k --resolve app.centralus.cloudapp.azure.com:443:<IP_OF_NGINX_CONTROLLER> https://appcentralus.cloudapp.azure.com
Create .pfx file
openssl pkcs12 -export -out app-tls.pfx -inkey app-tls.key -in app-tls.crt
