Running nginx as part of cf node app as multiprocess

[pyogesh2]

What version of Cloud Foundry and CF CLI are you using? (i.e. What is the output of running cf curl /v2/info && cf version?
cf api version 2.209.0
cf cli - cf version 7.5.0+0ad1d63.2022-06-04

What version of the buildpack you are using?
nginx_buildpack-cached-cflinuxfs4-v1.2.6.zip

If you were attempting to accomplish a task, what was it you were attempting to do?
We are trying run an application with multiple process, one being nginx and other one node-js. The nginx will have rate limiiting configuration and it routes to the nodejs process. (We dont want to use the cf route service).
Manifest configuration:

---
applications:
- name: cf-nodejs
  memory: 1G
  processes:
  - type: web
    command: nginx -p /home/vcap/app -c ./nginx.conf
    instances: 1
  - type: worker
    command: node server.js
    instances: 2
  random-route: true
  buildpacks: 
   - nginx_buildpack
   - nodejs_buildpack

nginx configuration:

worker_processes 1;
daemon off;

error_log stderr;
events { worker_connections 1024; }

http {
  charset utf-8;
  log_format cloudfoundry 'NginxLog "$request" $status $body_bytes_sent';
  resolver {{nameservers}};
  access_log /dev/stdout cloudfoundry;
  default_type application/octet-stream;
  sendfile on;

  tcp_nopush on;
  keepalive_timeout 30;
  port_in_redirect off; # Ensure that redirects don't include the internal container PORT - 8080


  limit_req_zone global zone=global_limit:128m rate=1r/s;

  server {
    listen {{port}};
  
    # configuration endpoint
    location / {
      default_type application/json;
      limit_req zone=global_limit burst=3; # rule of thumb: burst = rate * 3
      limit_req_status 429;
      proxy_pass https://localhost:4000;

    }
  }
}

What did you expect to happen?
Both the process should work.

What was the actual behavior?
Nodejs process was started and running, nginx process crashed with the error

Alternatively used the Procfile

web: nginx -p /home/vcap/app -c ./nginx.conf
worker: node server.js

We got the same error.

If we comment the resolver and listen port in the nginx.conf, that both process will be running but it is quite obvious it will not solve our purpose.

Please confirm where necessary:

• I have included a log output
• My log includes an error message
• I have included steps for reproduction

I am running into the same issue and getting the same error. Has there been any movement on this?
