Reverse Proxy Jira Cloud Servicedesk Portals

[Vishnu Agarwal]

Hi, 

My organization have 2 Servicedesk portals on Jira Cloud - 

1. <org>.atlassian.net/helpcenter/hr/  - HR
2. <org>.atlassian.net/helpcenter/it/   - IT

But when we try to setup Custom Domains for them, I am able to only set one common and also it does not take me to individual page but to a portals page- `<org>.atlassian.net/servicedesk/customer/portals` .

To avoid confusion and to secure the URL behind a VPN we were trying to setup Nginx Reverse Proxy, using Nginx ingress controller and K8s External Name service. 

But getting SSL Handshake error.

apiVersion: v1 
kind: Service 
metadata: 
  name: ithelp-service 
  namespace: test
spec: 
  externalName: org.atlassian.net  
  type: ExternalName

apiVersion: networking.k8s.io/v1 
kind: Ingress 
metadata: 
  annotations: 
    nginx.ingress.kubernetes.io/backend-protocol: HTTPS
    nginx.ingress.kubernetes.io/upstream-vhost: org.atlassian.net
  name: ithelp-ingress 
  namespace: test 
spec: 
  ingressClassName: test
  rules: 
  - host: ithelp-test.org-test.com // I have org-test domain and using proper certs
    http: 
      paths: 
      - backend: 
          service: 
            name: ithelp-service 
            port: 
              number: 443 
        path: / 
        pathType: Prefix

Please suggest next steps and help resolve this.

Thanks in advance.
