Types

type ContainerResponse 

type ContainerResponse struct {
	*v2.ContainerResponse
	Networks []Network `json:"Networks,omitempty"`
}

ContainerResponse is the v4 Container response. It augments the v4 Network response with the v2 container response object.

func GetContainerResponse added in v1.39.0 

func GetContainerResponse(containerID string, state dockerstate.TaskEngineState) (*ContainerResponse, error)

GetContainerResponse gets container response for v4 metadata

func NewContainerResponse 

func NewContainerResponse(
	containerID string,
	state dockerstate.TaskEngineState,
) (*ContainerResponse, error)

NewContainerResponse creates a new v4 container response based on container id. It augments v4 container response with additional network interface fields.

func NewPulledContainerResponse added in v1.48.0 

func NewPulledContainerResponse(
	dockerContainer *apicontainer.DockerContainer,
	eni *apieni.ENI,
) ContainerResponse

NewPulledContainerResponse creates a new v4 container response for a pulled container. It augments v4 container response with an additional empty network interface field.

type Network 

type Network struct {
	containermetadata.Network
	// NetworkInterfaceProperties specifies additional properties of the network
	// of the network interface that are exposed via the metadata server.
	// We currently populate this only for the `awsvpc` networking mode.
	NetworkInterfaceProperties
}

Network is the v4 Network response. It adds a bunch of information about network interface(s) on top of what is supported by v4. See `NetworkInterfaceProperties` for more details.

func GetContainerNetworkMetadata added in v1.39.0 

func GetContainerNetworkMetadata(containerID string, state dockerstate.TaskEngineState) ([]Network, error)

GetContainerNetworkMetadata returns the network metadata for the container

type NetworkInterfaceProperties 

type NetworkInterfaceProperties struct {
	// AttachmentIndex reflects the `index` specified by the customer (if any)
	// while creating the task with `awsvpc` mode.
	AttachmentIndex *int `json:"AttachmentIndex,omitempty"`
	// MACAddress is the MAC address of the network interface.
	MACAddress string `json:"MACAddress,omitempty"`
	// IPv4SubnetCIDRBlock is the IPv4 CIDR address block associated with the interface's subnet.
	IPV4SubnetCIDRBlock string `json:"IPv4SubnetCIDRBlock,omitempty"`
	// IPv6SubnetCIDRBlock is the IPv6 CIDR address block associated with the interface's subnet.
	IPv6SubnetCIDRBlock string `json:"IPv6SubnetCIDRBlock,omitempty"`
	// DomainNameServers specifies the nameserver IP addresses for the network interface.
	DomainNameServers []string `json:"DomainNameServers,omitempty"`
	// DomainNameSearchList specifies the search list for the domain name lookup for
	// the network interface.
	DomainNameSearchList []string `json:"DomainNameSearchList,omitempty"`
	// PrivateDNSName is the dns name assigned to this network interface.
	PrivateDNSName string `json:"PrivateDNSName,omitempty"`
	// SubnetGatewayIPV4Address is the IPv4 gateway address for the network interface.
	SubnetGatewayIPV4Address string `json:"SubnetGatewayIpv4Address,omitempty"`
}

NetworkInterfaceProperties represents additional properties we may want to expose via task metadata about the network interface that's attached to the container/task. We mostly use this to populate data about ENIs for tasks launched with `awsvpc` mode.

type StatsResponse added in v1.43.0 

type StatsResponse struct {
	*types.StatsJSON
	Network_rate_stats *stats.NetworkStatsPerSec `json:"network_rate_stats,omitempty"`
}

StatsResponse is the v4 Stats response. It augments the v4 Stats response with the docker stats.

type TaskResponse 

type TaskResponse struct {
	*v2.TaskResponse
	Containers []ContainerResponse `json:"Containers,omitempty"`
}

TaskResponse is the v4 Task response. It augments the v4 Container response with the v2 task response object.

func NewTaskResponse 

func NewTaskResponse(
	taskARN string,
	state dockerstate.TaskEngineState,
	ecsClient api.ECSClient,
	cluster string,
	az string,
	containerInstanceARN string,
	propagateTags bool,
) (*TaskResponse, error)

NewTaskResponse creates a new v4 response object for the task. It augments v2 task response with additional network interface fields.
