	PrivateDNSName string `json:",omitempty"`
	// SubnetGatewayIPV4Address is the address to the subnet gateway for
	// the eni
	SubnetGatewayIPV4Address string `json:",omitempty"`
}

ENI contains information of the eni

func ENIFromACS

func ENIFromACS(acsenis []*ecsacs.ElasticNetworkInterface) (*ENI, error)

ENIFromACS validates the information from acs message and create the ENI object

func (*ENI) GetHostname

func (eni *ENI) GetHostname() string

GetHostname returns the hostname assigned to the ENI

func (*ENI) GetIPV4Addresses

func (eni *ENI) GetIPV4Addresses() []string

GetIPV4Addresses returns a list of ipv4 addresses allocated to the ENI

func (*ENI) GetIPV6Addresses

func (eni *ENI) GetIPV6Addresses() []string

GetIPV6Addresses returns a list of ipv6 addresses allocated to the ENI

func (*ENI) GetSubnetGatewayIPV4Address

func (eni *ENI) GetSubnetGatewayIPV4Address() string

GetSubnetGatewayIPV4Address returns the subnet IPv4 gateway address assigned to the ENI

func (*ENI) String

func (eni *ENI) String() string

String returns a human readable version of the ENI object

type ENIAttachment

type ENIAttachment struct {
	// TaskARN is the task identifier from ecs
	TaskARN string `json:"taskArn"`
	// AttachmentARN is the identifier for the eni attachment
	AttachmentARN string `json:"attachmentArn"`
	// AttachStatusSent indicates whether the attached status has been sent to backend
	AttachStatusSent bool `json:"attachSent"`
	// MACAddress is the mac address of eni
	MACAddress string `json:"macAddress"`
	// Status is the status of the eni: none/attached/detached
	Status ENIAttachmentStatus `json:"status"`
	// ExpiresAt is the timestamp past which the ENI Attachment is considered
	// unsuccessful. The SubmitTaskStateChange API, with the attachment information
	// should be invoked before this timestamp.
	ExpiresAt time.Time `json:"expiresAt"`
	// contains filtered or unexported fields
}

ENIAttachment contains the information of the eni attachment

func (*ENIAttachment) HasExpired

func (eni *ENIAttachment) HasExpired() bool

HasExpired returns true if the ENI attachment object has exceeded the threshold for notifying the backend of the attachment

func (*ENIAttachment) IsSent

func (eni *ENIAttachment) IsSent() bool

IsSent checks if the eni attached status has been sent

func (*ENIAttachment) SetSentStatus

func (eni *ENIAttachment) SetSentStatus()

SetSentStatus marks the eni attached status has been sent

func (*ENIAttachment) StartTimer

func (eni *ENIAttachment) StartTimer(timeoutFunc func()) error

StartTimer starts the ack timer to record the expiration of ENI attachment

func (*ENIAttachment) StopAckTimer

func (eni *ENIAttachment) StopAckTimer()

StopAckTimer stops the ack timer set on the ENI attachment

func (*ENIAttachment) String
