2019/06/06 - Amazon EC2 Container Service - 1 new 10 updated api methods
Changes This release of Amazon Elastic Container Service (Amazon ECS) introduces support for launching container instances using supported Amazon EC2 instance types that have increased elastic network interface density. Using these instance types and opting in to the awsvpcTrunking account setting provides increased elastic network interface (ENI) density on newly launched container instances which allows you to place more tasks on each container instance.
Note
This action is only used by the Amazon ECS agent, and it is not intended for use outside of the agent.

{'containerInstance': {'statusReason': 'string'}}
Deregisters an Amazon ECS container instance from the specified cluster. This instance is no longer available to run tasks.
If you intend to use the container instance for some other purpose after deregistration, you should stop all of the tasks running on the container instance before deregistration. That prevents any orphaned tasks from consuming resources.
Deregistering a container instance removes the instance from a cluster, but it does not terminate the EC2 instance. If you are finished using the instance, be sure to terminate it in the Amazon EC2 console to stop billing.
Note
If you terminate a running container instance, Amazon ECS automatically deregisters the instance from your cluster (stopped container instances or instances with disconnected agents are not automatically deregistered when terminated).
See also: AWS API Documentation
Request Syntax
client.deregister_container_instance(
cluster='string',
containerInstance='string',
force=True|False
)
string
The short name or full Amazon Resource Name (ARN) of the cluster that hosts the container instance to deregister. If you do not specify a cluster, the default cluster is assumed.
string
[REQUIRED]
The container instance ID or full ARN of the container instance to deregister. 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 .
boolean
Forces the deregistration of the container instance. If you have tasks running on the container instance when you deregister it with the force option, these tasks remain running until you terminate the instance or the tasks stop through some other means, but they are orphaned (no longer monitored or accounted for by Amazon ECS). If an orphaned task on your container instance is part of an Amazon ECS service, then the service scheduler starts another copy of that task, on a different container instance if possible.
Any containers in orphaned service tasks that are registered with a Classic Load Balancer or an Application Load Balancer target group are deregistered. They begin connection draining according to the settings on the load balancer or target group.

ec2InstanceId (string) --
The EC2 instance ID of the container instance.
version (integer) --
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.

Modifies an account setting. For more information, see Account Settings in the Amazon Elastic Container Service Developer Guide .
When serviceLongArnFormat , taskLongArnFormat , or containerInstanceLongArnFormat are specified, the ARN and resource ID format of the resource type for a specified IAM user, IAM role, or the root user for an account is changed. If you change the account setting for the root user, the default settings for all of the IAM users and roles for which no individual account setting has been specified are reset. The opt-in and opt-out account setting can be specified for each Amazon ECS resource separately. The ARN and resource ID format of a resource will be defined by the opt-in status of the IAM user or role that created the resource. You must enable this setting to use Amazon ECS features such as resource tagging.
When awsvpcTrunking is specified, the elastic network interface (ENI) limit for any new container instances that support the feature is changed. If awsvpcTrunking is enabled, any new container instances that support the feature are launched have the increased ENI limits available to them. For more information, see Elastic Network Interface Trunking in the Amazon Elastic Container Service Developer Guide .

Updates the Amazon ECS container agent on a specified container instance. Updating the Amazon ECS container agent does not interrupt running tasks or services on the container instance. The process for updating the agent differs depending on whether your container instance was launched with the Amazon ECS-optimized AMI or another operating system.
UpdateContainerAgent requires the Amazon ECS-optimized AMI or Amazon Linux with the ecs-init service installed and running. For help updating the Amazon ECS container agent on other operating systems, see Manually Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide .

{'status': {'REGISTERING', 'DEREGISTERING', 'REGISTRATION_FAILED'}}
Response {'containerInstances': {'statusReason': 'string'}}
Modifies the status of an Amazon ECS container instance.
Once a container instance has reached an ACTIVE state, you can change the status of a container instance to DRAINING to manually remove an instance from a cluster, for example to perform system updates, update the Docker daemon, or scale down the cluster size.
Warning
A container instance cannot be changed to DRAINING until it has reached an ACTIVE status. If the instance is in any other status, an error will be received.
When you set a container instance to DRAINING , Amazon ECS prevents new tasks from being scheduled for placement on the container instance and replacement service tasks are started on other container instances in the cluster if the resources are available. Service tasks on the container instance that are in the PENDING state are stopped immediately.
Service tasks on the container instance that are in the RUNNING state are stopped and replaced according to the service's deployment configuration parameters, minimumHealthyPercent and maximumPercent . You can change the deployment configuration of your service using UpdateService.
If minimumHealthyPercent is below 100%, the scheduler can ignore desiredCount temporarily during task replacement. For example, desiredCount is four tasks, a minimum of 50% allows the scheduler to stop two existing tasks before starting two new tasks. If the minimum is 100%, the service scheduler can't remove existing tasks until the replacement tasks are considered healthy. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state. Tasks for services that use a load balancer are considered healthy if they are in the RUNNING state and the container instance they are hosted on is reported as healthy by the load balancer.
The maximumPercent parameter represents an upper limit on the number of running tasks during task replacement, which enables you to define the replacement batch size. For example, if desiredCount is four tasks, a maximum of 200% starts four new tasks before stopping the four tasks to be drained, provided that the cluster resources required to do this are available. If the maximum is 100%, then replacement tasks can't start until the draining tasks have stopped.
Any PENDING or RUNNING tasks that do not belong to a service are not affected. You must wait for them to finish or stop them manually.
A container instance has completed draining when it has no more RUNNING tasks. You can verify this using ListTasks.
When a container instance has been drained, you can set a container instance to ACTIVE status and once it has reached that status the Amazon ECS scheduler can begin scheduling tasks on the instance again.

Response Structure
(dict) --
containerInstances (list) --
The list of container instances.
(dict) --
An EC2 instance that is running the Amazon ECS agent and has been registered with a cluster.
containerInstanceArn (string) --
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 .
ec2InstanceId (string) --
The EC2 instance ID of the container instance.
version (integer) --
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.
versionInfo (dict) --
The version information for the Amazon ECS container agent and Docker daemon running on the container instance.
agentVersion (string) --
The version number of the Amazon ECS container agent.
agentHash (string) --
The Git commit hash for the Amazon ECS container agent build on the amazon-ecs-agent GitHub repository.
dockerVersion (string) --
The Docker version running on the container instance.
remainingResources (list) --
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.

(string) --
status (string) --
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 .
