Functions ¶

func FindFrontEndElbs ¶

func FindFrontEndElbs(awsElb ELB, frontendTagValue string) (map[string]LoadBalancerDetails, error)

FindFrontEndElbs supports finding ELBs without ingress class for backwards compatibility with feed-dns, which does not support multiple ingress controllers

func FindFrontEndElbsWithIngressClassName ¶

func FindFrontEndElbsWithIngressClassName(awsElb ELB, frontendTagValue string, ingressClassValue string) (map[string]LoadBalancerDetails, error)

FindFrontEndElbsWithIngressClassName finds all ELBs tagged with frontendTagValue and ingressClassValue

func New ¶

func New(region string, frontendTagValue string, ingressClassTagValue string, expectedNumber int, drainDelay time.Duration) (controller.Updater, error)

New creates a new ELB frontend

Types ¶

type EC2Metadata ¶

type EC2Metadata interface {
	Available() bool
	Region() (string, error)
	GetInstanceIdentityDocument() (ec2metadata.EC2InstanceIdentityDocument, error)
}

EC2Metadata interface to allow mocking of the real calls to AWS

type ELB ¶

type ELB interface {
	DescribeLoadBalancers(input *aws_elb.DescribeLoadBalancersInput) (*aws_elb.DescribeLoadBalancersOutput, error)
	DescribeTags(input *aws_elb.DescribeTagsInput) (*aws_elb.DescribeTagsOutput, error)
	RegisterInstancesWithLoadBalancer(input *aws_elb.RegisterInstancesWithLoadBalancerInput) (*aws_elb.RegisterInstancesWithLoadBalancerOutput, error)
	DeregisterInstancesFromLoadBalancer(input *aws_elb.DeregisterInstancesFromLoadBalancerInput) (*aws_elb.DeregisterInstancesFromLoadBalancerOutput, error)
}

ELB interface to allow mocking of real calls to AWS as well as cutting down the methods from the real interface to only the ones we use

type LoadBalancerDetails ¶

type LoadBalancerDetails struct {
	Name         string
	DNSName      string
	HostedZoneID string
	Scheme       string
}

LoadBalancerDetails stores all the elb information we use.
