#### What is this?
It is nginx latest mainline statically linked against LibreSSL latest snapshot, with embedded Brotli support.
Secured by default (no root processes, even the master one). I made this image for my own purpose, but I added some flexibility so you can use it easily.

#### Features
- Based on Alpine Linux (3.3) : lightweight and secure distribution.
- nginx mainline + LibreSSL snapshot
- HTTP/2 support.
- Brotli compression support.
- No root master process. Better security.
- AIO Threads support.
- No unnessary modules.
- Optimized nginx configuration.

#### Notes
It is required to :
- chown your certs files with the right uid/pid (no other way)
- change `listen` directive to 8000/4430 instead of 80/443

By the way, it is recommended to **build this image** (using docker-compose 1.6 and later for args compatibily) directly instead of pulling it from Docker Hub.

#### Volumes
- **/sites-enabled** : should contain your vhosts files (.conf)
- **/conf.d** : additional configuration files if you want
- **/certs** : SSL/TLS certificates
- **/var/log/nginx** : nginx logs (access and error)

#### Build arguments
- **NGINX_VER** : nginx's version, change it if needed but the default version is tested
- **LIBRESSL_VER** : same as NGINX_VER
- **GID** : nginx group id *(default : 991)*
- **UID** : nginx user id *(default : 991)*

#### Source (Dockerfile)
https://github.com/Wonderfall/dockerfiles/tree/master/reverse

#### Examples : compose, vhost, TLS conf

**NOTES** : 
- compose file must use version 2. [See more here](https://docs.docker.com/compose/compose-file/#version-2:91de898b5f5cdb090642a917d3dedf68).
- Docker 1.10+ and docker-compose 1.6+ are needed.
- if you're using docker-compose inside a container, pay attention to `context`.
