Overview

An EC2 instance that is running the Amazon ECS agent and has been registered with a cluster.

Returned by:

Instance Attribute Summary collapse

Instance Attribute Details

#agent_connectedBoolean

This parameter returns true if the agent is connected to Amazon ECS. Registered instances with an agent that may be unhealthy or stopped return false. Only instances connected to an agent can accept placement requests.

Returns:

  • (Boolean)

    This parameter returns true if the agent is connected to Amazon ECS.

#agent_update_statusString

The status of the most recent agent update. If an update has never been requested, this value is NULL.

Possible values:

  • PENDING
  • STAGING
  • STAGED
  • UPDATING
  • UPDATED
  • FAILED

Returns:

  • (String)

    The status of the most recent agent update.

#attachmentsArray<Types::Attachment>

The resources attached to a container instance, such as elastic network interfaces.

Returns:

  • (Array<Types::Attachment>)

    The resources attached to a container instance, such as elastic network interfaces.

#attributesArray<Types::Attribute>

The attributes set for the container instance, either by the Amazon ECS container agent at instance registration or manually with the PutAttributes operation.

Returns:

  • (Array<Types::Attribute>)

    The attributes set for the container instance, either by the Amazon ECS container agent at instance registration or manually with the PutAttributes operation.

#container_instance_arnString

The Amazon Resource Name (ARN) of the container instance. The ARN contains the arn:aws:ecs namespace, followed by the Region of the container instance, the AWS account ID of the container instance owner, the container-instance namespace, and then the container instance ID. For example, arn:aws:ecs:region:aws_account_id:container-instance/container_instance_ID.

Returns:

  • (String)

    The Amazon Resource Name (ARN) of the container instance.

#ec2_instance_idString

The EC2 instance ID of the container instance.

Returns:

  • (String)

    The EC2 instance ID of the container instance.

#pending_tasks_countInteger

The number of tasks on the container instance that are in the PENDING status.

Returns:

  • (Integer)

    The number of tasks on the container instance that are in the PENDING status.

#registered_atTime

The Unix timestamp for when the container instance was registered.

Returns:

  • (Time)

    The Unix timestamp for when the container instance was registered.

#registered_resourcesArray<Types::Resource>

For CPU and memory resource types, this parameter describes the amount of each resource that was available on the container instance when the container agent registered it with Amazon ECS. This value represents the total amount of CPU and memory that can be allocated on this container instance to tasks. For port resource types, this parameter describes the ports that were reserved by the Amazon ECS container agent when it registered the container instance with Amazon ECS.

Returns:

  • (Array<Types::Resource>)

    For CPU and memory resource types, this parameter describes the amount of each resource that was available on the container instance when the container agent registered it with Amazon ECS.

#remaining_resourcesArray<Types::Resource>

For CPU and memory resource types, this parameter describes the remaining CPU and memory that has not already been allocated to tasks and is therefore available for new tasks. For port resource types, this parameter describes the ports that were reserved by the Amazon ECS container agent (at instance registration time) and any task containers that have reserved port mappings on the host (with the host or bridge network mode). Any port that is not specified here is available for new tasks.

Returns:

  • (Array<Types::Resource>)

    For CPU and memory resource types, this parameter describes the remaining CPU and memory that has not already been allocated to tasks and is therefore available for new tasks.

#running_tasks_countInteger

The number of tasks on the container instance that are in the RUNNING status.

Returns:

  • (Integer)

    The number of tasks on the container instance that are in the RUNNING status.

#statusString

The status of the container instance. The valid values are REGISTERING, REGISTRATION_FAILED, ACTIVE, INACTIVE, DEREGISTERING, or DRAINING.

If your account has opted in to the awsvpcTrunking account setting, then any newly registered container instance will transition to a REGISTERING status while the trunk elastic network interface is provisioned for the instance. If the registration fails, the instance will transition to a REGISTRATION_FAILED status. You can describe the container instance and see the reason for failure in the statusReason parameter. Once the container instance is terminated, the instance transitions to a DEREGISTERING status while the trunk elastic network interface is deprovisioned. The instance then transitions to an INACTIVE status.

The ACTIVE status indicates that the container instance can accept tasks. The DRAINING indicates that new tasks are not placed on the container instance and any service tasks running on the container instance are removed if possible. For more information, see Container Instance Draining in the Amazon Elastic Container Service Developer Guide.

Returns:

  • (String)

    The status of the container instance.

#status_reasonString

The reason that the container instance reached its current status.

Returns:

  • (String)

    The reason that the container instance reached its current status.

#tagsArray<Types::Tag>

The metadata that you apply to the container instance to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define. Tag keys can have a maximum character length of 128 characters, and tag values can have a maximum length of 256 characters.

Returns:

  • (Array<Types::Tag>)

    The metadata that you apply to the container instance to help you categorize and organize them.

#versionInteger

The version counter for the container instance. Every time a container instance experiences a change that triggers a CloudWatch event, the version counter is incremented. If you are replicating your Amazon ECS container instance state with CloudWatch Events, you can compare the version of a container instance reported by the Amazon ECS APIs with the version reported in CloudWatch Events for the container instance (inside the detail object) to verify that the version in your event stream is current.

Returns:

  • (Integer)

    The version counter for the container instance.

#version_infoTypes::VersionInfo

The version information for the Amazon ECS container agent and Docker daemon running on the container instance.

Returns:

  • (Types::VersionInfo)

    The version information for the Amazon ECS container agent and Docker daemon running on the container instance.
