cf apps within warden cannot access public internet

[drnic]

When I deploy an app into CF within bosh-lite, it must have all its assets (and not use a public buildpack) as it cannot access the public internet:

Following https://github.com/cloudfoundry-community/container-info-buildpack/blob/master/README.md

I think this is connected to the intermittent DNS problem. Try the same up/down and see if it comes back?

New BOSH user here, I ran into these problems with Virtualbox repeatedly and resolved them when I added these two lines to the Vagrant file's virtualbox provider config:

config.vm.provider :virtualbox do |v, override|
# ...
v.customize ["modifyvm", :id, "--natdnshostresolver1", "on"]
v.customize ["modifyvm", :id, "--natdnsproxy1", "on"]
end

Which forwards DNS requests to the outer host and doesn't muck with the guest when DNS servers change due to switching DHCP networks. Also works well with offline modes using Dnsmasq.

Just tried @drnic's test case above with a fresh bosh-lite and it worked fine.
