# About this docker-compose This `docker-compose` files can be used for production purpose. ![Architecture](https://github.com/btcpayserver/btcpayserver-doc/raw/master/img/Architecture.png) This is the same architecture as [Production](../Production) but without NGINX as a reverse proxy. It is suited for environment which already expose the host behind a reverse proxy handling HTTPS. The relevant environment variables are: * `NBITCOIN_NETWORK`: the blockchain identifier used by NBitcoin (eg., `regtest`, `testnet`, `mainnet`) * `BTCPAY_HOST`: the external url used to access your server from internet. This domain name must point to this machine. * `BTCPAY_PROTOCOL`: the protocol used to access this website from the internet (valid values: `http` and `https`, default: `https`) The port `80` is exposed. Note that you need to set `BTCPAY_PROTOCOL=http` if you want to do some tests locally without https. If you forget, you will get an error HTTP 400 when trying to register a new account on the website.
