Nginx Advanced Setup

https://nginxproxymanager.com/advanced-config/

Will need to create Network in Portainer if using the below
Add this to the bottom of your nginx compose file

networks:
  default:
    external: true
    name: nginx

You will need to add this to every docker container(compose file) that you want Nginx to redirect
Comment out the ports on any docker container(ie wordpress) you add this external network in
You will use the original port (ie 80, whichever port is to the right in the compose file) for the redirect port in the setup
You will use the Docker name instead of the IP

Nginx troubleshooting

Most of these issues I came across while using Cloudflare:

  1. If having an error message for too many redirects: https://github.com/NginxProxyManager/nginx-proxy-manager/issues/852
    "The cloudflare proxy does not actually follow the redirect nginx sends, which results in this error. You probably need to set the SSL/TLS encryption mode to Full or Full (Strict) or remove the additional CloudFlare proxy."
