Variables ¶
var InstanceENIsAvailable = map[string]int{}/* 140 elements not displayed */
InstanceENIsAvailable contains a mapping of instance types to the number of ENIs available which is described at https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.html#AvailableIpPerENI
var InstanceIPsAvailable = map[string]int64{}/* 140 elements not displayed */
InstanceIPsAvailable contains a mapping of instance types to the number of IPs per ENI https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.html#AvailableIpPerENI

type APIs ¶
type APIs interface { // AllocENI creates an eni and attaches it to instance AllocENI(useCustomCfg bool, sg []*string, subnet string) (eni string, err error) // FreeENI detaches eni interface and deletes it FreeENI(eniName string) error // GetAttachedENIs retrieves eni information from instance metadata service GetAttachedENIs() (eniList []ENIMetadata, err error) // DescribeENI returns the IPv4 addresses of eni interface and eni attachment id DescribeENI(eniID string) (addrList []*ec2.NetworkInterfacePrivateIpAddress, attachemdID *string, err error) // AllocIPAddress allocates an ip address for an eni AllocIPAddress(eniID string) error // AllocAllIPAddress allocates all ip addresses available on an eni AllocAllIPAddress(eniID string) error // Allocate alloactes numIPs of IP address on a eni AllocIPAddresses(eniID string, numIPs int64) error // GetVPCIPv4CIDR returns vpc's cidr GetVPCIPv4CIDR() string // GetLocalIPv4 returns the primary IP address on the primary eni interface GetLocalIPv4() string // GetPrimaryENI returns the primary eni GetPrimaryENI() string // GetENIipLimit returns the number IP address can be allocated on a ENI GetENIipLimit() (int64, error) // GetENILimit returns the number of enis can be attached to an instance GetENILimit() (int, error) }
APIs defines interfaces calls for adding/getting/deleting ENIs/secondary IPs. The APIs are not thread-safe.
