Motivation¶

• Creating a 1,2 or many k8s cluster should be a matter of "working seconds" and "setup minutes"

Environment¶

• Assume you have an IPv6 network, f.i. a /48
• Assume you have a router, such as bird
• Assume you have a dynamic number of hosts ("k8s hosts")
• Assume every k8s cluster will use 2x /64's
  • one for pods
  • one for services (effectively only /108 is used, but that is an implementation detail)
• Assume you can (and should) delegate the subnetworks of the /48 "automatically"
  • i.e. define ranges that can be automatically deployed

Steps¶

• define how to create nodes
  • either virtual or hardware nodes
• define how nodes are getting their networking
