simple cf cli plugin to resolve bosh based DNS names

DNS Resolver CF Plugin

Overview

The plugin exposes the resolve command, which takes a host name and resolves it to an IP address using the standard dig command. Out of the list of started apps in the current space, the command attempts to open an ssh tunnel in a sequential manner. Once there is a successful ssh connection, the host name is resolved.

The standard host command is used to pre-resolve the host name. Then, the dig command is executed with the argument supplied to cf resolve to echo the IP address on console.

Usage

cf resolve <bosh based host name>

Cautions

For the plugin to resolve successfully,

1. There should be a valid session connected via cf login
2. The currently logged in Org should support ssh connectivity in general
