Installing PGP Key for Yum Repos Through Python API

Question

I have looked at similar questions but no one mentions how I should approach this. I wanted to write a quick and dirty script that would help me bootstrap Puppet on fresh Fedora installs for some stuff I wanna try. From perusing the questions here. I had some sample code fixed up for my needs.

[root@srv ~]# python puppet-bootstrap.py 
[ 11/03/2012 02:16:47 PM ] begin bootstrap install for puppet client
[ 11/03/2012 02:16:47 PM ] package not found on system, installing

    raise Errors.YumBaseError, _("Didn't install any keys")
yum.Errors.YumBaseError: Didn't install any keys

So how would I go about write a brief little code to accept the PGP key through the YUM Python API? The distro in question would be almost untouched, so the PGP key would have to be properly signed off in the case of this script. Anyone done this before?

Please add

yb.conf.assumeyes = True

Where appropriate. Egyou code should look like this:

#!/usr/bin/python
import yum

yb = yum.YumBase()
yb.conf.installroot = "/ipportvm/gittest/rootfs_testrootfs"
yb.conf.assumeyes = True
yb.conf.yumvar['releasever'] = '6'
for i in ("openssh-server", "plymouth", "rsyslog", "acpid", "ntp", "epel-release"):
    yb.install(name=i)
yb.resolveDeps()
yb.buildTransaction()
yb.processTransaction()
