Hi Stephen,

You generally never want to alter the manifest templates unless you're
making a PR with general improvements to the templates. Customizing your
own deployment should be done either within your stub(s), or modifying your
spiff-generated manifest with your desired changes before deploying.

Try making the following additions to your stub:

jobs:
- name: ha_proxy_z1
instances: 1
networks:
- name: ha_proxy_z1_elastic
static_ips: [YOUR_STATIC_IP_HERE]
- name: cf1
default: [gateway, dns]

networks:
- name: ha_proxy_z1_elastic # Add this network to the existing cf1 and cf2
networks, don't remove those
type: vip

resource_pools:
- name: router_z1
cloud_properties:
elbs: []
- name: router_z2
cloud_properties:
elbs: []

See if that works for you. You will need to make sure that you've
configured DNS records so that your system domain and app domains point to
YOUR_STATIC_IP for ha_proxy. If you're already using YOUR_STATIC_IP.xip.io
as your system and apps domains, then this will work without having to
create any DNS records.

Best,
Amit
