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. Potentially solving with increasing timeouts.

proxy_connect_timeout 60s;
proxy_read_timeout 60s;
proxy_send_timeout 60s;
