Multi host

This is the core modification to K8's to support flannel networking. The overall implementation has been abstracted enough to be generic to most deployments.

There are a few things going on here we should be cognizant of:

• Networking CIDR applies to both the K8s services, and the flannel network configuration
• Any other layer implementation will need to follow the same guidelines, pass a cidr between both
• we're pulling containers from quay.io and gcr.io - both of which will not make it past the firewall test
• Once libnetwork takes over, this layer is likely to go away all together in favor of a unified libnetwork layer to configure the different providers

The flannel layer can be found here

Glad to have the new name of the file, charm-tools 1.8.0 allowed this, right?

[chuckbutler]

Correct. as of 1.8.0 this is fully supported.

good catch @chuckbutler

Regarding

"we're pulling containers from quay.io and gcr.io - both of which will not make it past the firewall test"

We have to balance the firewall test with how the industry is recommending the distribution of the releases. At the moment this seems to be the way it is going, perhaps we will have to pull the images from another location at some point in the future

+1 on that comment. I just felt it was prudent to leave somewhere that we should be cognizant of it :)
