Network.AWS.EC2.Metadata

Contents

Description

Retrieve an EC2 instance's local metadata.

Synopsis

Requests

Running on EC2

isEC2 :: Manager -> IO Bool Source

Test whether the host is running on EC2 by requesting the instance-data.

Dynamic

data Dynamic Source

Constructors

FWS

Value showing whether the customer has enabled detailed one-minute monitoring in CloudWatch.

Valid values: enabled | disabled.

Document

JSON containing instance attributes, such as instance-id, private IP address, etc.

PKCS7

Used to verify the document's authenticity and content against the signature.

Instances

Metadata

data Metadata Source

Constructors

AMIId

The AMI ID used to launch the instance.

AMILaunchIndex

If you started more than one instance at the same time, this value indicates the order in which the instance was launched. The value of the first instance launched is 0.

AMIManifestPath

The path to the AMI's manifest file in Amazon S3. If you used an Amazon EBS-backed AMI to launch the instance, the returned result is unknown.

AncestorAMIIds

The AMI IDs of any instances that were rebundled to create this AMI. This value will only exist if the AMI manifest file contained an ancestor-amis key.

BlockDevice !Mapping

See: Mapping

Hostname

The private hostname of the instance. In cases where multiple network interfaces are present, this refers to the eth0 device (the device for which the device number is 0).

IAM !Info

See: Info

InstanceAction

Notifies the instance that it should reboot in preparation for bundling. Valid values: none | shutdown | bundle-pending.

InstanceId

The ID of this instance.

InstanceType

The type of instance.

See: InstanceType

KernelId

The ID of the kernel launched with this instance, if applicable.

LocalHostname

The private DNS hostname of the instance. In cases where multiple network interfaces are present, this refers to the eth0 device (the device for which the device number is 0).

LocalIPV4

The private IP address of the instance. In cases where multiple network interfaces are present, this refers to the eth0 device (the device for which the device number is 0).

MAC

The instance's media access control (MAC) address. In cases where multiple network interfaces are present, this refers to the eth0 device (the device for which the device number is 0).

Network !Text !Interface

See: Interface

AvailabilityZone

The Availability Zone in which the instance launched.

ProductCodes

Product codes associated with the instance, if any.

PublicHostname

The instance's public DNS. If the instance is in a VPC, this category is only returned if the enableDnsHostnames attribute is set to true. For more information, see Using DNS with Your VPC.

PublicIPV4

The public IP address. If an Elastic IP address is associated with the instance, the value returned is the Elastic IP address.

OpenSSHKey

Public key. Only available if supplied at instance launch time.

RAMDiskId

The ID of the RAM disk specified at launch time, if applicable.

ReservationId

ID of the reservation.

SecurityGroups

The names of the security groups applied to the instance.

data Mapping Source

Constructors

AMI

The virtual device that contains the root/boot file system.

EBS !Int

The virtual devices associated with Amazon EBS volumes, if present. This value is only available in metadata if it is present at launch time. The N indicates the index of the Amazon EBS volume (such as ebs1 or ebs2).

Ephemeral !Int

The virtual devices associated with ephemeral devices, if present. The N indicates the index of the ephemeral volume.

Root

The virtual devices or partitions associated with the root devices, or partitions on the virtual device, where the root (/ or C:) file system is associated with the given instance.

Swap

The virtual devices associated with swap. Not always present.

data Info Source

Constructors

Info

Returns information about the last time the instance profile was updated, including the instance's LastUpdated date, InstanceProfileArn, and InstanceProfileId.

SecurityCredentials (Maybe Text)

Where role-name is the name of the IAM role associated with the instance. Returns the temporary security credentials.

See: Auth for JSON deserialisation.

Instances

data Interface Source

Constructors

IDeviceNumber

The device number associated with that interface. Each interface must have a unique device number. The device number serves as a hint to device naming in the instance; for example, device-number is 2 for the eth2 device.

IIPV4Associations !Text

The private IPv4 addresses that are associated with each public-ip address and assigned to that interface.

ILocalHostname

The interface's local hostname.

ILocalIPV4s

The private IP addresses associated with the interface.

IMAC

The instance's MAC address.

IOwnerId

The ID of the owner of the network interface. In multiple-interface environments, an interface can be attached by a third party, such as Elastic Load Balancing. Traffic on an interface is always billed to the interface owner.

IPublicHostname

The interface's public DNS. If the instance is in a VPC, this category is only returned if the enableDnsHostnames attribute is set to true. For more information, see Using DNS with Your VPC.

IPublicIPV4s

The Elastic IP addresses associated with the interface. There may be multiple IP addresses on an instance.

ISecurityGroups

Security groups to which the network interface belongs. Returned only for instances launched into a VPC.

ISecurityGroupIds

IDs of the security groups to which the network interface belongs. Returned only for instances launched into a VPC. For more information on security groups in the EC2-VPC platform, see Security Groups for Your VPC.

ISubnetId

The ID of the subnet in which the interface resides. Returned only for instances launched into a VPC.

ISubnetIPV4_CIDRBlock

The CIDR block of the subnet in which the interface resides. Returned only for instances launched into a VPC.

IVPCId

The ID of the VPC in which the interface resides. Returned only for instances launched into a VPC.

IVPCIPV4_CIDRBlock

The CIDR block of the VPC in which the interface resides. Returned only for instances launched into a VPC.
