/**
 * HostPort annotation is used to inject the bound port to a container object.
 * Typically a docker image has an exposed port which is bound to a binding port (to access from outside).
 * With this annotation you set the exposed port, and Cube will inject the bind port associated to this exposed port.
 * <p>
 * For example given: 2222->22/tcp and using:
 *
 * @HostPort(22) int port;
 * <p>
 * Port value will be 2222.
