It imports the specified subnets into ClusterConfig and sets the AZs and local zones used by those subnets. NOTE: it does respect all fields set in spec.VPC, and will error if there is a mismatch of local vs remote states

func ImportSubnetsByIDsWithAlias added in v0.112.0

func ImportSubnetsFromSpec added in v0.39.0 

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

func MakeExtendedSubnetAlias added in v0.112.0 

func MakeExtendedSubnetAlias(az string, ordinal int) string

SelectNodeGroupSubnets returns the subnet IDs to use for a nodegroup from the specified availability zones, local zones, and subnets.

func SetSubnets 

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

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

func SplitInto added in v0.112.0 

func SplitInto(parent *net.IPNet, size, networkLength int) ([]*net.IPNet, error)

func UseEndpointAccessFromCluster 

func UseEndpointAccessFromCluster(ctx context.Context, 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 UseFromClusterStack added in v0.40.0 

func UseFromClusterStack(ctx context.Context, provider api.ClusterProvider, stack *types.Stack, spec *api.ClusterConfig) error

UseFromClusterStack 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(ctx context.Context, provider api.ClusterProvider, vpcID string, subnetIDs []string) error

ValidateExistingPublicSubnets makes sure that subnets have the property MapPublicIpOnLaunch enabled

func ValidateLegacySubnetsForNodeGroups 

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