Overview
An API client for ECS. To construct a client, you need to configure a :region
and :credentials
.
client = Aws::ECS::Client.new(
region: region_name,
credentials: credentials,
# ...
)
For details on configuring region and credentials see the developer guide.

Instance Method Details
#create_capacity_provider(params = {}) ⇒ Types::CreateCapacityProviderResponse
Creates a new capacity provider. Capacity providers are associated with an Amazon ECS cluster and are used in capacity provider strategies to facilitate cluster auto scaling.
Only capacity providers that use an Auto Scaling group can be created.
Amazon ECS tasks on Fargate use the FARGATE
and FARGATE_SPOT
capacity providers. These providers are available to all accounts in
the Amazon Web Services Regions that Fargate supports.

#create_cluster(params = {}) ⇒ Types::CreateClusterResponse
Creates a new Amazon ECS cluster. By default, your account receives a
default
cluster when you launch your first container instance.
However, you can create your own cluster with a unique name.

# File 'gems/aws-sdk-ecs/lib/aws-sdk-ecs/client.rb', line 817 def create_cluster(params = {}, = {}) req = build_request(:create_cluster, params) req.send_request() end |
#create_service(params = {}) ⇒ Types::CreateServiceResponse
Runs and maintains your desired number of tasks from a specified task
definition. If the number of tasks running in a service drops below
the desiredCount
, Amazon ECS runs another copy of the task in the
specified cluster. To update an existing service, use
UpdateService.
In addition to maintaining the desired count of tasks in your service, you can optionally run your service behind one or more load balancers. The load balancers distribute traffic across the tasks that are associated with the service. For more information, see Service load balancing in the Amazon Elastic Container Service Developer Guide.
You can attach Amazon EBS volumes to Amazon ECS tasks by configuring
the volume when creating or updating a service. volumeConfigurations
is only supported for REPLICA service and not DAEMON service. For more
infomation, see Amazon EBS volumes in the Amazon Elastic
Container Service Developer Guide.
Tasks for services that don't use a load balancer are considered
healthy if they're in the RUNNING
state. Tasks for services that
use a load balancer are considered healthy if they're in the
RUNNING
state and are reported as healthy by the load balancer.
There are two service scheduler strategies available:
REPLICA
- The replica scheduling strategy places and maintains your desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions. For more information, see Service scheduler concepts in the Amazon Elastic Container Service Developer Guide.DAEMON
- The daemon scheduling strategy deploys exactly one task on each active container instance that meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks. It also stops tasks that don't meet the placement constraints. When using this strategy, you don't need to specify a desired number of tasks, a task placement strategy, or use Service Auto Scaling policies. For more information, see Service scheduler concepts in the Amazon Elastic Container Service Developer Guide.
You can optionally specify a deployment configuration for your
service. The deployment is initiated by changing properties. For
example, the deployment might be initiated by the task definition or
by your desired count of a service. You can use UpdateService.
The default value for a replica service for minimumHealthyPercent
is
100%. The default value for a daemon service for
minimumHealthyPercent
is 0%.
If a service uses the ECS
deployment controller, the minimum healthy
percent represents a lower limit on the number of tasks in a service
that must remain in the RUNNING
state during a deployment.
Specifically, it represents it as a percentage of your desired number
of tasks (rounded up to the nearest integer). This happens when any of
your container instances are in the DRAINING
state if the service
contains tasks using the EC2 launch type. Using this parameter, you
can deploy without using additional cluster capacity. For example, if
you set your service to have desired number of four tasks and a
minimum healthy percent of 50%, the scheduler might stop two existing
tasks to free up cluster capacity before starting two new tasks. If
they're in the RUNNING
state, tasks for services that don't use a
load balancer are considered healthy . If they're in the RUNNING
state and reported as healthy by the load balancer, tasks for services
that do use a load balancer are considered healthy . The default
value for minimum healthy percent is 100%.
If a service uses the ECS
deployment controller, the maximum
percent parameter represents an upper limit on the number of tasks
in a service that are allowed in the RUNNING
or PENDING
state
during a deployment. Specifically, it represents it as a percentage of
the desired number of tasks (rounded down to the nearest integer).
This happens when any of your container instances are in the
DRAINING
state if the service contains tasks using the EC2 launch
type. Using this parameter, you can define the deployment batch size.
For example, if your service has a desired number of four tasks and a
maximum percent value of 200%, the scheduler may start four new tasks
before stopping the four older tasks (provided that the cluster
resources required to do this are available). The default value for
maximum percent is 200%.
If a service uses either the CODE_DEPLOY
or EXTERNAL
deployment
controller types and tasks that use the EC2 launch type, the minimum
healthy percent and maximum percent values are used only to
define the lower and upper limit on the number of the tasks in the
service that remain in the RUNNING
state. This is while the
container instances are in the DRAINING
state. If the tasks in the
service use the Fargate launch type, the minimum healthy percent and
maximum percent values aren't used. This is the case even if they're
currently visible when describing your service.
When creating a service that uses the EXTERNAL
deployment
controller, you can specify only parameters that aren't controlled at
the task set level. The only required parameter is the service name.
You control your services using the CreateTaskSet. For more
information, see Amazon ECS deployment types in the Amazon
Elastic Container Service Developer Guide.
When the service scheduler launches new tasks, it determines task placement. For information about task placement and task placement strategies, see Amazon ECS task placement in the Amazon Elastic Container Service Developer Guide

#delete_capacity_provider(params = {}) ⇒ Types::DeleteCapacityProviderResponse
Deletes the specified capacity provider.
FARGATE
and FARGATE_SPOT
capacity providers are reserved and
can't be deleted. You can disassociate them from a cluster using
either PutCapacityProviderProviders or by deleting the cluster.
Prior to a capacity provider being deleted, the capacity provider must
be removed from the capacity provider strategy from all services. The
UpdateService API can be used to remove a capacity provider from
a service's capacity provider strategy. When updating a service, the
forceNewDeployment
option can be used to ensure that any tasks using
the Amazon EC2 instance capacity provided by the capacity provider are
transitioned to use the capacity from the remaining capacity
providers. Only capacity providers that aren't associated with a
cluster can be deleted. To remove a capacity provider from a cluster,
you can either use PutClusterCapacityProviders or delete the
cluster.

#delete_cluster(params = {}) ⇒ Types::DeleteClusterResponse
Deletes the specified cluster. The cluster transitions to the
INACTIVE
state. Clusters with an INACTIVE
status might remain
discoverable in your account for a period of time. However, this
behavior is subject to change in the future. We don't recommend that
you rely on INACTIVE
clusters persisting.
You must deregister all container instances from this cluster before you may delete it. You can list the container instances in a cluster with ListContainerInstances and deregister them with DeregisterContainerInstance.

#delete_service(params = {}) ⇒ Types::DeleteServiceResponse
Deletes a specified service within a cluster. You can delete a service if you have no running tasks in it and the desired task count is zero. If the service is actively maintaining tasks, you can't delete it, and you must update the service to a desired task count of zero. For more information, see UpdateService.
ACTIVE
to DRAINING
,
and the service is no longer visible in the console or in the
ListServices API operation. After all tasks have transitioned to
either STOPPING
or STOPPED
status, the service status moves from
DRAINING
to INACTIVE
. Services in the DRAINING
or INACTIVE
status can still be viewed with the DescribeServices API
operation. However, in the future, INACTIVE
services may be cleaned
up and purged from Amazon ECS record keeping, and
DescribeServices calls on those services return a
ServiceNotFoundException
error.
If you attempt to create a new service with the same name as an
existing service in either ACTIVE
or DRAINING
status, you receive
an error.

#delete_task_definitions(params = {}) ⇒ Types::DeleteTaskDefinitionsResponse
Deletes one or more task definitions.
You must deregister a task definition revision before you delete it. For more information, see DeregisterTaskDefinition.
When you delete a task definition revision, it is immediately
transitions from the INACTIVE
to DELETE_IN_PROGRESS
. Existing
tasks and services that reference a DELETE_IN_PROGRESS
task
definition revision continue to run without disruption. Existing
services that reference a DELETE_IN_PROGRESS
task definition
revision can still scale up or down by modifying the service's
desired count.
You can't use a DELETE_IN_PROGRESS
task definition revision to run
new tasks or create new services. You also can't update an existing
service to reference a DELETE_IN_PROGRESS
task definition revision.
A task definition revision will stay in DELETE_IN_PROGRESS
status
until all the associated tasks and services have been terminated.
When you delete all INACTIVE
task definition revisions, the task
definition name is not displayed in the console and not returned in
the API. If a task definition revisions are in the
DELETE_IN_PROGRESS
state, the task definition name is displayed in
the console and returned in the API. The task definition name is
retained by Amazon ECS and the revision is incremented the next time
you create a task definition with that name.

#deregister_container_instance(params = {}) ⇒ Types::DeregisterContainerInstanceResponse
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, we recommend that you 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 doesn't terminate the EC2 instance. If you are finished using the instance, be sure to terminate it in the Amazon EC2 console to stop billing.

#deregister_task_definition(params = {}) ⇒ Types::DeregisterTaskDefinitionResponse
Deregisters the specified task definition by family and revision. Upon
deregistration, the task definition is marked as INACTIVE
. Existing
tasks and services that reference an INACTIVE
task definition
continue to run without disruption. Existing services that reference
an INACTIVE
task definition can still scale up or down by modifying
the service's desired count. If you want to delete a task definition
revision, you must first deregister the task definition revision.
You can't use an INACTIVE
task definition to run new tasks or
create new services, and you can't update an existing service to
reference an INACTIVE
task definition. However, there may be up to a
10-minute window following deregistration where these restrictions
have not yet taken effect.
INACTIVE
task definitions remain discoverable in your
account indefinitely. However, this behavior is subject to change in
the future. We don't recommend that you rely on INACTIVE
task
definitions persisting beyond the lifecycle of any associated tasks
and services.
You must deregister a task definition revision before you delete it. For more information, see DeleteTaskDefinitions.

#put_cluster_capacity_providers(params = {}) ⇒ Types::PutClusterCapacityProvidersResponse
Modifies the available capacity providers and the default capacity provider strategy for a cluster.
You must specify both the available capacity providers and a default capacity provider strategy for the cluster. If the specified cluster has existing capacity providers associated with it, you must specify all existing capacity providers in addition to any new ones you want to add. Any existing capacity providers that are associated with a cluster that are omitted from a PutClusterCapacityProviders API call will be disassociated with the cluster. You can only disassociate an existing capacity provider from a cluster if it's not being used by any existing tasks.
When creating a service or running a task on a cluster, if no capacity
provider or launch type is specified, then the cluster's default
capacity provider strategy is used. We recommend that you define a
default capacity provider strategy for your cluster. However, you must
specify an empty array ([]
) to bypass defining a default strategy.

#register_task_definition(params = {}) ⇒ Types::RegisterTaskDefinitionResponse
Registers a new task definition from the supplied family
and
containerDefinitions
. Optionally, you can add data volumes to your
containers with the volumes
parameter. For more information about
task definition parameters and defaults, see Amazon ECS Task
Definitions in the Amazon Elastic Container Service Developer
Guide.
You can specify a role for your task with the taskRoleArn
parameter.
When you specify a role for a task, its containers can then use the
latest versions of the CLI or SDKs to make API requests to the Amazon
Web Services services that are specified in the policy that's
associated with the role. For more information, see IAM Roles for
Tasks in the Amazon Elastic Container Service Developer Guide.
You can specify a Docker networking mode for the containers in your
task definition with the networkMode
parameter. If you specify the
awsvpc
network mode, the task is allocated an elastic network
interface, and you must specify a NetworkConfiguration when you
create a service or run a task with the task definition. For more
information, see Task Networking in the Amazon Elastic Container
Service Developer Guide.

#run_task(params = {}) ⇒ Types::RunTaskResponse
Starts a new task using the specified task definition.
You can allow Amazon ECS to place tasks for you, or you can customize how Amazon ECS places tasks using placement constraints and placement strategies. For more information, see Scheduling Tasks in the Amazon Elastic Container Service Developer Guide.
Alternatively, you can use StartTask
to use your own scheduler or
place tasks manually on specific container instances.
You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when creating or updating a service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide.
The Amazon ECS API follows an eventual consistency model. This is because of the distributed nature of the system supporting the API. This means that the result of an API command you run that affects your Amazon ECS resources might not be immediately visible to all subsequent commands you run. Keep this in mind when you carry out an API command that immediately follows a previous API command.
To manage eventual consistency, you can do the following:
Confirm the state of the resource before you run a command to modify it. Run the DescribeTasks command using an exponential backoff algorithm to ensure that you allow enough time for the previous command to propagate through the system. To do this, run the DescribeTasks command repeatedly, starting with a couple of seconds of wait time and increasing gradually up to five minutes of wait time.
Add wait time between subsequent commands, even if the DescribeTasks command returns an accurate response. Apply an exponential backoff algorithm starting with a couple of seconds of wait time, and increase gradually up to about five minutes of wait time.

#stop_task(params = {}) ⇒ Types::StopTaskResponse
Stops a running task. Any tags associated with the task will be deleted.
When you call StopTask
on a task, the equivalent of docker stop
is
issued to the containers running in the task. This results in a
SIGTERM
value and a default 30-second timeout, after which the
SIGKILL
value is sent and the containers are forcibly stopped. If
the container handles the SIGTERM
value gracefully and exits within
30 seconds from receiving it, no SIGKILL
value is sent.
For Windows containers, POSIX signals do not work and runtime stops
the container by sending a CTRL_SHUTDOWN_EVENT
. For more
information, see Unable to react to graceful shutdown of (Windows)
container #25982 on GitHub.

#update_container_agent(params = {}) ⇒ Types::UpdateContainerAgentResponse
Updates the Amazon ECS container agent on a specified container instance. Updating the Amazon ECS container agent doesn't 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
API isn't supported for container
instances using the Amazon ECS-optimized Amazon Linux 2 (arm64) AMI.
To update the container agent, you can update the ecs-init
package.
This updates the agent. For more information, see Updating the Amazon
ECS container agent in the Amazon Elastic Container Service
Developer Guide.
UpdateContainerAgent
API operation do not
apply to Windows container instances. We recommend that you launch new
container instances to update the agent version in your Windows
clusters.
The UpdateContainerAgent
API requires an Amazon ECS-optimized AMI or
Amazon Linux AMI 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.

#update_container_instances_state(params = {}) ⇒ Types::UpdateContainerInstancesStateResponse
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.
A container instance can't 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 ignoredesiredCount
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're in theRUNNING
state. Tasks for services that use a load balancer are considered healthy if they're in theRUNNING
state and are reported as healthy by the load balancer.The
maximumPercent
parameter represents an upper limit on the number of running tasks during task replacement. You can use this to define the replacement batch size. For example, ifdesiredCount
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
aren't 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.

#update_service(params = {}) ⇒ Types::UpdateServiceResponse
Modifies the parameters of a service.
For services using the rolling update (ECS
) you can update the
desired count, deployment configuration, network configuration, load
balancers, service registries, enable ECS managed tags option,
propagate tags option, task placement constraints and strategies, and
task definition. When you update any of these parameters, Amazon ECS
starts new tasks with the new configuration.
You can attach Amazon EBS volumes to Amazon ECS tasks by configuring
the volume when starting or running a task, or when creating or
updating a service. For more infomation, see Amazon EBS volumes
in the Amazon Elastic Container Service Developer Guide. You can
update your volume configurations and trigger a new deployment.
volumeConfigurations
is only supported for REPLICA service and not
DAEMON service. If you leave volumeConfigurations
null
, it
doesn't trigger a new deployment. For more infomation on volumes, see
Amazon EBS volumes in the Amazon Elastic Container Service
Developer Guide.
For services using the blue/green (CODE_DEPLOY
) deployment
controller, only the desired count, deployment configuration, health
check grace period, task placement constraints and strategies, enable
ECS managed tags option, and propagate tags can be updated using this
API. If the network configuration, platform version, task definition,
or load balancer need to be updated, create a new CodeDeploy
deployment. For more information, see CreateDeployment in the
CodeDeploy API Reference.
For services using an external deployment controller, you can update only the desired count, task placement constraints and strategies, health check grace period, enable ECS managed tags option, and propagate tags option, using this API. If the launch type, load balancer, network configuration, platform version, or task definition need to be updated, create a new task set For more information, see CreateTaskSet.
You can add to or subtract from the number of instantiations of a task
definition in a service by specifying the cluster that the service is
running in and a new desiredCount
parameter.
You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when starting or running a task, or when creating or updating a service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide.
If you have updated the container image of your application, you can create a new task definition with that image and deploy it to your service. The service scheduler uses the minimum healthy percent and maximum percent parameters (in the service's deployment configuration) to determine the deployment strategy.
my_image:latest
), you don't need to create a new revision of your
task definition. You can update the service using the
forceNewDeployment
option. The new tasks launched by the deployment
pull the current image/tag combination from your repository when they
start.
You can also update the deployment configuration of a service. When a
deployment is triggered by updating the task definition of a service,
the service scheduler uses the deployment configuration parameters,
minimumHealthyPercent
and maximumPercent
, to determine the
deployment strategy.
If
minimumHealthyPercent
is below 100%, the scheduler can ignoredesiredCount
temporarily during a deployment. For example, ifdesiredCount
is four tasks, a minimum of 50% allows the scheduler to stop two existing tasks before starting two new tasks. Tasks for services that don't use a load balancer are considered healthy if they're in theRUNNING
state. Tasks for services that use a load balancer are considered healthy if they're in theRUNNING
state and are reported as healthy by the load balancer.The
maximumPercent
parameter represents an upper limit on the number of running tasks during a deployment. You can use it to define the deployment batch size. For example, ifdesiredCount
is four tasks, a maximum of 200% starts four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available).
When UpdateService stops a task during a deployment, the
equivalent of docker stop
is issued to the containers running in the
task. This results in a SIGTERM
and a 30-second timeout. After this,
SIGKILL
is sent and the containers are forcibly stopped. If the
container handles the SIGTERM
gracefully and exits within 30 seconds
from receiving it, no SIGKILL
is sent.
When the service scheduler launches new tasks, it determines task placement in your cluster with the following logic.
Determine which of the container instances in your cluster can support your service's task definition. For example, they have the required CPU, memory, ports, and container instance attributes.
By default, the service scheduler attempts to balance tasks across Availability Zones in this manner even though you can choose a different placement strategy.
Sort the valid container instances by the fewest number of running tasks for this service in the same Availability Zone as the instance. For example, if zone A has one running service task and zones B and C each have zero, valid container instances in either zone B or C are considered optimal for placement.
Place the new service task on a valid container instance in an optimal Availability Zone (based on the previous steps), favoring container instances with the fewest number of running tasks for this service.
When the service scheduler stops running tasks, it attempts to maintain balance across the Availability Zones in your cluster using the following logic:
Sort the container instances by the largest number of running tasks for this service in the same Availability Zone as the instance. For example, if zone A has one running service task and zones B and C each have two, container instances in either zone B or C are considered optimal for termination.
Stop the task on a container instance in an optimal Availability Zone (based on the previous steps), favoring container instances with the largest number of running tasks for this service.

Modifies which task set in a service is the primary task set. Any
parameters that are updated on the primary task set in a service will
transition to the service. This is used when a service uses the
EXTERNAL
deployment controller type. For more information, see
Amazon ECS Deployment Types in the Amazon Elastic Container
Service Developer Guide.

#update_task_protection(params = {}) ⇒ Types::UpdateTaskProtectionResponse
Updates the protection status of a task. You can set
protectionEnabled
to true
to protect your task from termination
during scale-in events from Service Autoscaling or
deployments.
Task-protection, by default, expires after 2 hours at which point
Amazon ECS clears the protectionEnabled
property making the task
eligible for termination by a subsequent scale-in event.
You can specify a custom expiration period for task protection from 1
minute to up to 2,880 minutes (48 hours). To specify the custom
expiration period, set the expiresInMinutes
property. The
expiresInMinutes
property is always reset when you invoke this
operation for a task that already has protectionEnabled
set to
true
. You can keep extending the protection expiration period of a
task by invoking this operation repeatedly.
To learn more about Amazon ECS task protection, see Task scale-in protection in the Amazon Elastic Container Service Developer Guide .
TASK_NOT_VALID
failure. For more information, see API failure
reasons.
If you prefer to set task protection from within the container, we recommend using the Task scale-in protection endpoint.

#wait_until(waiter_name, params = {}, options = {}) {|w.waiter| ... } ⇒ Boolean
Polls an API operation until a resource enters a desired state.
Basic Usage
A waiter will call an API operation until:
- It is successful
- It enters a terminal state
- It makes the maximum number of attempts
In between attempts, the waiter will sleep.
# polls in a loop, sleeping between attempts
client.wait_until(waiter_name, params)
Configuration
You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You can pass configuration as the final arguments hash.
# poll for ~25 seconds
client.wait_until(waiter_name, params, {
max_attempts: 5,
delay: 5,
})
Callbacks
You can be notified before each polling attempt and before each
delay. If you throw :success
or :failure
from these callbacks,
it will terminate the waiter.
started_at = Time.now
client.wait_until(waiter_name, params, {
# disable max attempts
max_attempts: nil,
# poll for 1 hour, instead of a number of attempts
before_wait: -> (attempts, response) do
throw :failure if Time.now - started_at > 3600
end
})
Handling Errors
When a waiter is unsuccessful, it will raise an error. All of the failure errors extend from Waiters::Errors::WaiterFailed.
begin
client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
# resource did not enter the desired state in time
end
Valid Waiters
The following table lists the valid waiter names, the operations they call,
and the default :delay
and :max_attempts
values.
waiter_name | params | :delay | :max_attempts |
---|---|---|---|
services_inactive | #describe_services | 15 | 40 |
services_stable | #describe_services | 15 | 40 |
tasks_running | #describe_tasks | 6 | 100 |
tasks_stopped | #describe_tasks | 6 | 100 |
