Constants

const (
	// AnnotationLoadBalancerSourceRangesKey is the key of the annotation on a service to set allowed ingress ranges on their LoadBalancers
	//
	// It should be a comma-separated list of CIDRs, e.g. `0.0.0.0/0` to
	// allow full access (the default) or `18.0.0.0/8,56.0.0.0/8` to allow
	// access only from the CIDRs currently allocated to MIT & the USPS.
	//
	// Not all cloud providers support this annotation, though AWS & GCE do.

Functions

func GetLoadBalancerSourceRanges

func GetLoadBalancerSourceRanges(annotations map[string]string) (netsets.IPNet, error)

GetLoadBalancerSourceRanges verifies and parses the AnnotationLoadBalancerSourceRangesKey annotation from a service, extracting the source ranges to allow, and if not present returns a default (allow-all) value.

func IsAllowAll

func IsAllowAll(ipnets netsets.IPNet) bool

IsAllowAll checks whether the netsets.IPNet allows traffic from 0.0.0.0/0
