GCE Multiple K8s DC C* Deployment - Networking

[chrislovecnm]

@paralin please submit a PR for getting muitple DC's Racks on GCE.

1. Bash scripts for networking
2. VPN Docker
3. Documentation

Once you have submitted a PR, let me know and I can get you a baby k8s cluster.

for rack I would just specify the rack name as the node attribute for availability zone

for DC most of what youre going to do is configuration in the GCE UI

[chrislovecnm]

so nothing in GCE ui please. Please do all through gcloud api 😄

Bash is beautiful.

Or if you are really adventurous you can do terraform ...

@paralin have you worked out the networking as of yet with vpn?

[paralin]

Yes it works. At least for the purpose of bridging 2 clusters.

@paralin when will you have a chance to document? I will mention on Monday that examples are coming for multiple physical Datacenter K8s installs with Multiple DC C*, are coming.

The demo will have two Datacenters btw. I stopped the custom seedprovider, and went to DNS. Do you know of a way to have nodetool use DNS rather than IPs? IPs are not guaranteed with PetSets ... we may have a challenge with Token ranges :(
