brooklyn.entity.proxy.nginx
[Java] Class NginxControllerImpl

java.lang.Object
  brooklyn.entity.basic.AbstractEntity
      brooklyn.entity.basic.SoftwareProcessImpl
          brooklyn.entity.proxy.AbstractControllerImpl
              brooklyn.entity.proxy.nginx.NginxControllerImpl
All Implemented Interfaces:
NginxController
public class NginxControllerImpl
extends AbstractControllerImpl

An entity that represents an Nginx proxy (e.g. for routing requests to servers in a cluster).

The default driver *builds* nginx from source (because binaries are not reliably available, esp not with sticky sessions). This requires gcc and other build tools installed. The code attempts to install them but inevitably this entity may be more finicky about the OS/image where it runs than others.

Paritcularly on OS X we require Xcode and command-line gcc installed and on the path.

See http for useful info/examples of configuring nginx.

https configuration is supported, with the certificates providable on a per-UrlMapping basis or a global basis. (not supported to define in both places.) per-Url is useful if different certificates are used for different server names, or different ports if that is supported. see more info on Ssl in ProxySslConfig.
