Using Proxies in magnum if running under firewall

If you are running magnum behind a firewall then you may need a proxy for using services like docker, kubernetes and mesos. Use these steps when your firewall will not allow you to use those services without a proxy.

NOTE: This feature has only been tested with the supported cluster type and associated image: Kubernetes and Swarm use the Fedora Atomic image, and Mesos uses the Ubuntu image.

Proxy Parameters to define before use

1. http-proxy

Address of a proxy that will receive all HTTP requests and relay them. The format is a URL including a port number. For example: http://10.11.12.13:8000 or http://abcproxy.com:8000

2. https-proxy

Address of a proxy that will receive all HTTPS requests and relay them. The format is a URL including a port number. For example: https://10.11.12.13:8000 or https://abcproxy.com:8000

3. no-proxy

A comma separated list of IP addresses or hostnames that should bypass your proxy, and make connections directly.

NOTE: You may not express networks/subnets. It only accepts names and ip addresses. Bad example: 192.168.0.0/28.

Steps to configure proxies.

You can specify all three proxy parameters while creating ClusterTemplate of any coe type. All of proxy parameters are optional.
