Functions

func CreateOrUpdate

func CreateOrUpdate(ctx context.Context, client client.Interface, node *api.Node) (*api.Node, error)

CreateOrUpdate creates the Node if ResourceVersion is not specified, or Update if it's specified.

func GenerateIPv6ULAPrefix

func GenerateIPv6ULAPrefix() (string, error)

generateIPv6ULAPrefix return a random generated ULA IPv6 prefix as per RFC 4193. The pool is generated from bytes pulled from a secure random source.

func Run

func Run()

This file contains the main startup processing for the calico/node. This includes:

• Detecting IP address and Network to use for BGP
• Configuring the node resource with IP/AS information provided in the environment, or autodetected.
• Creating default IP Pools for quick-start use
