Functions

func CleanupNetworkInterfaces

func CleanupNetworkInterfaces(ec2API ec2iface.EC2API, spec *api.ClusterConfig) error

CleanupNetworkInterfaces finds and deletes any dangling ENIs

func EnsureMapPublicIPOnLaunchEnabled

func EnsureMapPublicIPOnLaunchEnabled(ec2API ec2iface.EC2API, subnetIDs []string) error

EnsureMapPublicIPOnLaunchEnabled will enable MapPublicIpOnLaunch in EC2 for all given subnet IDs

func ImportSubnets

func ImportSubnets(ec2API ec2iface.EC2API, spec *api.ClusterConfig, topology api.SubnetTopology, subnets []*ec2.Subnet) error

ImportSubnets will update spec with subnets, if VPC ID/CIDR is unknown it will use provider to call describeVPC based on the VPC ID of the first subnet; all subnets must be in the same VPC NOTE: it does respect all fields set in spec.VPC, and will error if there is a mismatch of local vs remote states

func ImportSubnetsFromIDList

func ImportSubnetsFromIDList(ec2API ec2iface.EC2API, spec *api.ClusterConfig, topology api.SubnetTopology, subnetIDs []string) error

ImportSubnetsFromIDList will update spec with subnets _only specified by ID_ then pass resulting subnets to ImportSubnets NOTE: it does respect all fields set in spec.VPC, and will error if there is a mismatch of local vs remote states

func ImportSubnetsFromSpec

func ImportSubnetsFromSpec(provider api.ClusterProvider, spec *api.ClusterConfig) error

ImportSubnetsFromSpec will update spec with subnets, it will call describeSubnets first, then pass resulting subnets to ImportSubnets NOTE: it does respect all fields set in spec.VPC, and will error if there is a mismatch of local vs remote states

func SelectNodeGroupSubnets

func SelectNodeGroupSubnets(nodegroupAZs, nodegroupSubnets []string, subnets api.AZSubnetMapping) ([]string, error)

func SetSubnets

func SetSubnets(vpc *api.ClusterVPC, availabilityZones []string) error

SetSubnets defines CIDRs for each of the subnets, it must be called after SetAvailabilityZones

func SplitInto16

func SplitInto16(parent *net.IPNet) ([]*net.IPNet, error)

func SplitInto8

func SplitInto8(parent *net.IPNet) ([]*net.IPNet, error)

func UseEndpointAccessFromCluster

func UseEndpointAccessFromCluster(provider api.ClusterProvider, spec *api.ClusterConfig) error

UseEndpointAccessFromCluster retrieves the Cluster's endpoint access configuration via the SDK as the CloudFormation Stack doesn't support that configuration currently

func UseFromCluster

func UseFromCluster(provider api.ClusterProvider, stack *cfn.Stack, spec *api.ClusterConfig) error

UseFromCluster retrieves the VPC configuration from an existing cluster based on stack outputs NOTE: it doesn't expect any fields in spec.VPC to be set, the remote state is treated as the source of truth

func ValidateExistingPublicSubnets

func ValidateExistingPublicSubnets(provider api.ClusterProvider, vpcID string, subnetIDs []string) error

ValidateExistingPublicSubnets makes sure that subnets have the property MapPublicIpOnLaunch enabled

func ValidateLegacySubnetsForNodeGroups

func ValidateLegacySubnetsForNodeGroups(spec *api.ClusterConfig, provider api.ClusterProvider) error
