Install WebGateway

Hi Thiago,

there is an example created by @Dmitry Maslennikov 
 of how to install WebGateway along with apache inside a docker-container: https://github.com/caretdev/iris-webgateway-example . It is a bit outdated but a very good starting point, we use it with only few modifications. You might need to to find the right version of Webgateway as tgz-archive. 

Use WebGateway container.
