Hi Anurag,
Please check out the docs on how Fabric executes your tasks:
http://docs.fabfile.org/0.9/usage/execution.html
The key here is that right now, only the @hosts decorators for the
task actually called on the command line will take effect -- not
subtasks.
If you can provide more details I could give you a better idea of how
to work around this for the time being.
For example, if your example is almost literally how your code looks,
you could set env.host_string = "x...@google.com" inside deploy() above
the call to rdeploy(). Then any run() or sudo() or put(), etc etc,
calls inside rdeploy() would connect to "x...@google.com" as you
intended.
If your @hosts line sets >1 host, you could simply wrap the rdeploy()
call in a loop which does the same thing (sets env.host_string, calls
rdeploy().)
Also note that this behavior is highly likely to be upgraded in the
future to become more flexible:

Best,
Jeff
