func NewELBV2 

func NewELBV2(awsconfig *aws.Config) *ELBV2

NewELBV2 returns an ELBV2 based off of the provided aws.Config

func (*ELBV2) AddListener 

func (e *ELBV2) AddListener(in elbv2.CreateListenerInput) (*elbv2.Listener, error)

AddListener creates a new Listener and associates it with the ELBV2 (ALB). It returns the elbv2.Listener created on success or an error on failure.

func (*ELBV2) AddRule 

func (e *ELBV2) AddRule(in elbv2.CreateRuleInput) (*elbv2.Rule, error)

AddRule creates a new Rule and associates it with the Listener. It returns the elbv2.Rule created on success or an error returned on failure.

func (*ELBV2) AddTargetGroup 

func (e *ELBV2) AddTargetGroup(in elbv2.CreateTargetGroupInput) (*elbv2.TargetGroup, error)

AddTargetGroup creates a new TargetGroup in AWS. It returns the created elbv2.TargetGroup on success and an error on failure.

func (*ELBV2) Create 

func (e *ELBV2) Create(in elbv2.CreateLoadBalancerInput) (*elbv2.LoadBalancer, error)

Create makes a new ELBV2 (ALB) in AWS. It returns the elbv2.LoadBalancer created on success or an error on failure.

func (*ELBV2) Delete 

func (e *ELBV2) Delete(in elbv2.DeleteLoadBalancerInput) error

Delete removes an ELBV2 (ALB) in AWS. It returns an error if the delete fails. Deletions of ALBs in AWS will also remove all listeners and rules associated with them.

func (*ELBV2) DescribeListeners 

func (e *ELBV2) DescribeListeners(loadBalancerArn *string) ([]*elbv2.Listener, error)

DescribeListeners looks up all ELBV2 (ALB) listeners in AWS that are part of the cluster.

func (*ELBV2) DescribeLoadBalancers 

func (e *ELBV2) DescribeLoadBalancers(clusterName *string) ([]*elbv2.LoadBalancer, error)

DescribeLoadBalancers looks up all ELBV2 (ALB) instances in AWS that are part of the cluster.

func (*ELBV2) DescribeRules 

func (e *ELBV2) DescribeRules(listenerArn *string) ([]*elbv2.Rule, error)

DescribeRules looks up all rules for a listener ARN.

func (*ELBV2) DescribeTags 

func (e *ELBV2) DescribeTags(arn *string) (util.Tags, error)

DescribeTags looks up all tags for a given ARN.

func (*ELBV2) DescribeTargetGroup 

func (e *ELBV2) DescribeTargetGroup(arn *string) (*elbv2.TargetGroup, error)

DescribeTargetGroup looks up a target group by an ARN.

func (*ELBV2) DescribeTargetGroupTargets 

func (e *ELBV2) DescribeTargetGroupTargets(arn *string) (util.AWSStringSlice, error)

DescribeTargetGroupTargets looks up target group targets by an ARN.

func (*ELBV2) DescribeTargetGroups 

func (e *ELBV2) DescribeTargetGroups(loadBalancerArn *string) ([]*elbv2.TargetGroup, error)

DescribeTargetGroups looks up all ELBV2 (ALB) target groups in AWS that are part of the cluster.

func (*ELBV2) ModifyTargetGroup 

func (e *ELBV2) ModifyTargetGroup(in elbv2.ModifyTargetGroupInput) (*elbv2.TargetGroup, error)

ModifyTargetGroup alters a Target Group in AWS. The modified elbv2.TargetGroup is returned on success and an error is returned on failure.

func (*ELBV2) RegisterTargets 

func (e *ELBV2) RegisterTargets(in elbv2.RegisterTargetsInput) error

RegisterTargets adds EC2 instances to a Target Group. It returns an error when unsuccessful.

func (*ELBV2) RemoveListener 

func (e *ELBV2) RemoveListener(in elbv2.DeleteListenerInput) error

RemoveListener removes a Listener from an ELBV2 (ALB) by deleting it in AWS. If the deletion attempt returns a elbv2.ErrCodeListenerNotFoundException, it's considered a success as the listener has already been removed. If removal fails for another reason, an error is returned.

func (*ELBV2) RemoveRule

RemoveRule removes a Rule from a listener by deleting it in AWS. If the deletion fails, an error is returned.

func (*ELBV2) RemoveTargetGroup 

func (e *ELBV2) RemoveTargetGroup(in elbv2.DeleteTargetGroupInput) error

RemoveTargetGroup removes a Target Group from AWS by deleting it. If the deletion fails, an error is returned. Often, a Listener that references the Target Group is still being deleted when this method is accessed.

func (*ELBV2) SetSecurityGroups 

func (e *ELBV2) SetSecurityGroups(in elbv2.SetSecurityGroupsInput) error

SetSecurityGroups updates the security groups attached to an ELBV2 (ALB). It returns an error when unsuccessful.

func (*ELBV2) SetSubnets 

func (e *ELBV2) SetSubnets(in elbv2.SetSubnetsInput) error

SetSubnets updates the subnets attached to an ELBV2 (ALB). It returns an error when unsuccessful.

func (*ELBV2) UpdateTags 

func (e *ELBV2) UpdateTags(arn *string, old util.Tags, new util.Tags) error

UpdateTags compares the new (desired) tags against the old (current) tags. It then adds and removes tags as needed.

type Route53 

type Route53 struct {

}

Route53 is our extension to AWS's route53.Route53

func NewRoute53 

func NewRoute53(awsconfig *aws.Config) *Route53

NewRoute53 returns a new Route53 based off of an aws.Config

func (*Route53) Delete 

func (r *Route53) Delete(in route53.ChangeResourceRecordSetsInput) error

Delete removes a Route53 Resource Record Set from Route 53. When a route53.InvalidChangeBatch error is detected, it's considered a failure as the Route 53 record no longer exists in its current states (is likley already deleted). All other failures return an error.

func (*Route53) DescribeResourceRecordSets 

func (r *Route53) DescribeResourceRecordSets(zoneID *string, hostname *string) (*route53.ResourceRecordSet, error)

DescribeResourceRecordSets returns the route53.ResourceRecordSet for a zone & hostname

func (*Route53) GetZoneID 

func (r *Route53) GetZoneID(hostname *string) (*route53.HostedZone, error)

GetZoneID looks for the Route53 zone ID of the hostname passed to it

func (*Route53) Modify 

func (r *Route53) Modify(in route53.ChangeResourceRecordSetsInput) error

Modify is the general way to interact with Route 53 Resource Record Sets. It handles create and modifications based on the input passed. It will verify the AWS DNS is propogated before returning.
