func ENIFromACS 

func ENIFromACS(acsENI *ecsacs.ElasticNetworkInterface) (*ENI, error)

ENIFromACS validates the given ACS ENI information and creates an ENI object from it.

func (*ENI) GetHostname 

func (eni *ENI) GetHostname() string

GetHostname returns the hostname assigned to the ENI

func (*ENI) GetIPAddressesWithPrefixLength

GetIPAddressesWithPrefixLength returns the list of all IP addresses assigned to the ENI with their subnet prefix length.

func (*ENI) GetIPV4Addresses 

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

GetIPV4Addresses returns the list of IPv4 addresses assigned to the ENI.

func (*ENI) GetIPV6Addresses 

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

GetIPV6Addresses returns the list of IPv6 addresses assigned to the ENI.

func (*ENI) GetIPv4SubnetCIDRBlock 

func (eni *ENI) GetIPv4SubnetCIDRBlock() string

GetIPv4SubnetCIDRBlock returns the IPv4 CIDR block, if any, of the ENI's subnet.

func (*ENI) GetIPv4SubnetPrefixLength 

func (eni *ENI) GetIPv4SubnetPrefixLength() string

GetIPv4SubnetPrefixLength returns the IPv4 prefix length of the ENI's subnet.

func (*ENI) GetIPv6SubnetCIDRBlock 

func (eni *ENI) GetIPv6SubnetCIDRBlock() string

GetIPv6SubnetCIDRBlock returns the IPv6 CIDR block, if any, of the ENI's subnet.

func (*ENI) GetLinkName 

func (eni *ENI) GetLinkName() string

GetLinkName returns the name of the ENI on the instance.

func (*ENI) GetPrimaryIPv4Address 

func (eni *ENI) GetPrimaryIPv4Address() string

GetPrimaryIPv4Address returns the primary IPv4 address assigned to the ENI.

func (*ENI) GetPrimaryIPv4AddressWithPrefixLength 

func (eni *ENI) GetPrimaryIPv4AddressWithPrefixLength() string

GetPrimaryIPv4AddressWithPrefixLength returns the primary IPv4 address assigned to the ENI with its subnet prefix length.

func (*ENI) GetSubnetGatewayIPv4Address 

func (eni *ENI) GetSubnetGatewayIPv4Address() string

GetSubnetGatewayIPv4Address returns the subnet gateway IPv4 address for the ENI.

func (*ENI) IsStandardENI 

func (eni *ENI) IsStandardENI() bool

IsStandardENI returns true if the ENI is a standard/regular ENI. That is, if it has its association protocol as standard. To be backwards compatible, if the association protocol is not set for an ENI, it's considered a standard ENI as well.

func (*ENI) String 

func (eni *ENI) String() string

String returns a human readable version of the ENI object

type ENIAttachment 

type ENIAttachment struct {
	attachment.AttachmentInfo
	// AttachmentType is the type of the eni attachment, can either be "task-eni" or "instance-eni"
	AttachmentType string `json:"attachmentType"`
	// MACAddress is the mac address of eni
	MACAddress string `json:"macAddress"`
	// contains filtered or unexported fields
}

ENIAttachment contains the information of the eni attachment

func (*ENIAttachment) GetAttachmentARN 

func (eni *ENIAttachment) GetAttachmentARN() string

func (*ENIAttachment) GetAttachmentType 

func (eni *ENIAttachment) GetAttachmentType() string

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) Initialize 

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

Initialize initializes the fields that can't be populated from loading state file. Notably, this initializes the ack timer so that if we times out waiting for the eni to be attached, the attachment can be removed from state.

func (*ENIAttachment) IsSent 

func (eni *ENIAttachment) IsSent() bool

IsSent checks if the eni attached status has been sent

func (*ENIAttachment) SetAttachedStatus
