docker-nginx

Nginx image based on docker-alpine with s6 overlay for containers.

While building the following steps are executed:

• Nginx 1.9.x is built with modules:
  • openresty/echo-nginx-module - brings "echo", "sleep", "time", "exec" and more shell commands to config file;
  • openresty/lua-nginx-module - embed the power of Lua into Nginx HTTP servers;
  • yaoweibin/nginx_upstream_check_module - add the support of upstream server health checks;
  • and standard http/2 module is enabled.
• Sample Lua module and configuration module are attached.
• IPv6 is disabled inside container.

Lua-nginx-module

Lua module gives a practically unlimited abilities for HTTP requests handling. It's extremely fast thanks to LuaJIT and non-blocking thanks to Nginx nature.

lua-example.conf demonstrates how to use external Lua modules. For example:

location /lua {
    content_by_lua_block {
        ngx.say("Hello, world!")
    }
}
```

It's an equivalent for:

```
location /echo {
    echo "Hello, world!";
}
```

This module allows to plugin external Lua functions (modules), integrate into Nginx request handling phases, invoke subrequests and much more.
