Nginx reverse proxy manager

Custom Headers

1. Volume for config in docker compose file:

    [..]
    volumes:
      - ./volumes/data:/data

2. Create custom configs in volumes/data/nginx/custom/ e.g. server_proxy.conf

https://nginxproxymanager.com/advanced-config/#custom-nginx-configurations

3. Test nginx cfg

# test nginx cfg
nginx -t

Errors

could not build optimal proxy_headers_hash, you should increase either proxy_headers_hash_max_size: 512 or proxy_headers_hash_bucket_size: 64

1. Create custom server_proxy.conf in volumes/data/nginx/custom/

proxy_headers_hash_max_size 1024;
proxy_headers_hash_bucket_size 128;

2. Test nginx cfg

# test nginx cfg
nginx -t

3. Increase values in 1. until error is gone

Occasional 502 connect errors

Sometimes there are 502 connector errors in the first requests, especially for proxy hosts.
