CfnCapacityProvider

class aws_cdk.aws_ecs.CfnCapacityProvider(scope, id, *, auto_scaling_group_provider=None, name=None, tags=None)

Bases: CfnResource

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 AWS Fargate use the FARGATE and FARGATE_SPOT capacity providers. These providers are available to all accounts in the AWS Regions that AWS Fargate supports.

Example:

# The code below shows an example of how to instantiate this type.
# The values are placeholders you should change.
from aws_cdk import aws_ecs as ecs

cfn_capacity_provider = ecs.CfnCapacityProvider(self, "MyCfnCapacityProvider",
    auto_scaling_group_provider=ecs.CfnCapacityProvider.AutoScalingGroupProviderProperty(
        auto_scaling_group_arn="autoScalingGroupArn",

        # the properties below are optional
        managed_draining="managedDraining",
        managed_scaling=ecs.CfnCapacityProvider.ManagedScalingProperty(
            instance_warmup_period=123,
            maximum_scaling_step_size=123,

    ),
    name="name",
    tags=[CfnTag(
        key="key",
        value="value"
    )]
)

Parameters:

scope (Construct) – Scope in which this resource is defined.
id (str) – Construct identifier for this resource (unique in its scope).
auto_scaling_group_provider (Union[IResolvable, AutoScalingGroupProviderProperty, Dict[str, Any], None]) – The Auto Scaling group settings for the capacity provider.
name (Optional[str]) – The name of the capacity provider. If a name is specified, it cannot start with aws , ecs , or fargate . If no name is specified, a default name in the CFNStackName-CFNResourceName-RandomString format is used.
tags (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – The metadata that you apply to the capacity provider to help you categorize and organize it. Each tag consists of a key and an optional value. You define both. The following basic restrictions apply to tags: - Maximum number of tags per resource - 50 - For each resource, each tag key must be unique, and each tag key can have only one value. - Maximum key length - 128 Unicode characters in UTF-8 - Maximum value length - 256 Unicode characters in UTF-8 - If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : /

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters:: path (str) – The path of the value to delete.
Return type:: None

add_dependency(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters:

target (CfnResource) –

Return type:

None

add_depends_on(target)

(deprecated) Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

Parameters:

target (CfnResource) –

Deprecated:

use addDependency

Stability:

deprecated

Return type:

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters:

key (str) –
value (Any) –

See:

Return type:

None

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
  "GlobalSecondaryIndexes": [
    {
      "Projection": {
        "NonKeyAttributes": [ "myattribute" ]
        ...
      }
      ...
    },
    {
      "ProjectionType": "INCLUDE"
      ...
    },
  ]
  ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

Parameters:

path (str) –
- The path of the property, you can use dot notation to override values in complex types. Any intermediate keys will be created as needed.
value (Any) –
- The value. Could be primitive or complex.

Return type:

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters:: property_path (str) – The path to the property.
Return type:: None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters:

property_path (str) – The path of the property.
value (Any) – The value.

Return type:

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT). A list of resources that support this policy can be found in the following link:

Parameters:

policy (Optional[RemovalPolicy]) –
apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true
default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resource, please consult that specific resource’s documentation.

See:

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-deletionpolicy.html#aws-attribute-deletionpolicy-options

Return type:

None

get_att(attribute_name, type_hint=None)

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

Parameters:

attribute_name (str) – The name of the attribute.
type_hint (Optional[ResolutionTypeHint]) –

Return type:

Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters:

key (str) –

See:

Return type:

Any

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

inspect(inspector)

Examines the CloudFormation resource and discloses attributes.

Parameters:: inspector (TreeInspector) – tree inspector to collect and process attributes.
Return type:: None

obtain_dependencies()

Retrieves an array of resources this resource depends on.

This assembles dependencies on resources across stacks (including nested stacks) automatically.

Return type:: List[Union[Stack, CfnResource]]

obtain_resource_dependencies()

target (CfnResource) –

Return type:

None

replace_dependency(target, new_target)

Replaces one dependency with another.

Parameters:

target (CfnResource) – The dependency to replace.
new_target (CfnResource) – The new dependency to add.

Return type:

None

to_string()

Returns a string representation of this construct.

Return type:: str
Returns:: a string representation of this resource

Attributes

CFN_RESOURCE_TYPE_NAME = 'AWS::ECS::CapacityProvider'

auto_scaling_group_provider: The Auto Scaling group settings for the capacity provider.

cfn_options: Options for this resource, such as condition, update policy etc.

cfn_resource_type: AWS resource type.

creation_stack

return:

the stack trace of the point where this Resource was created from, sourced from the +metadata+ entry typed +aws:cdk:logicalId+, and with the bottom-most node +internal+ entries filtered.

logical_id

The logical ID for this CloudFormation stack element.

The logical ID of the element is calculated from the path of the resource node in the construct tree.

To override this value, use overrideLogicalId(newLogicalId).

Returns:

the logical ID as a stringified token. This value will only get resolved during synthesis.

name: The name of the capacity provider.

node: The tree node.

ref

Return a string that will be resolved to a CloudFormation { Ref } for this element.

If, by any chance, the intrinsic reference of a resource is not a string, you could coerce it to an IResolvable through Lazy.any({ produce: resource.ref }).

stack

The stack in which this element is defined.

CfnElements must be defined within a stack scope (directly or indirectly).

tags: Tag Manager which manages the tags for this resource.

tags_raw: The metadata that you apply to the capacity provider to help you categorize and organize it.

Static Methods

classmethod is_cfn_element(x)

Returns true if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of instanceof to allow stack elements from different versions of this library to be included in the same stack.

Parameters:

x (Any) –

Return type:

bool

Returns:

The construct as a stack element or undefined if it is not a stack element.

classmethod is_cfn_resource(x)

Check whether the given object is a CfnResource.

Parameters:

x (Any) –

Return type:

bool

classmethod is_construct(x)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters:: x (Any) – Any object.
Return type:: bool
Returns:: true if x is an object created from a class which extends Construct.

AutoScalingGroupProviderProperty

class CfnCapacityProvider.AutoScalingGroupProviderProperty(*, auto_scaling_group_arn, managed_draining=None, managed_scaling=None, managed_termination_protection=None)

Bases: object

The details of the Auto Scaling group for the capacity provider.

Parameters:

auto_scaling_group_arn (str) – The Amazon Resource Name (ARN) that identifies the Auto Scaling group, or the Auto Scaling group name.
managed_draining (Optional[str]) – The managed draining option for the Auto Scaling group capacity provider. When you enable this, Amazon ECS manages and gracefully drains the EC2 container instances that are in the Auto Scaling group capacity provider.
managed_scaling (Union[IResolvable, ManagedScalingProperty, Dict[str, Any], None]) – The managed scaling settings for the Auto Scaling group capacity provider.
managed_termination_protection (Optional[str]) – The managed termination protection setting to use for the Auto Scaling group capacity provider. This determines whether the Auto Scaling group has managed termination protection. The default is off. .. epigraph:: When using managed termination protection, managed scaling must also be used otherwise managed termination protection doesn’t work. When managed termination protection is on, Amazon ECS prevents the Amazon EC2 instances in an Auto Scaling group that contain tasks from being terminated during a scale-in action. The Auto Scaling group and each instance in the Auto Scaling group must have instance protection from scale-in actions on as well. For more information, see Instance Protection in the AWS Auto Scaling User Guide . When managed termination protection is off, your Amazon EC2 instances aren’t protected from termination when the Auto Scaling group scales in.

)

Attributes

auto_scaling_group_arn

The Amazon Resource Name (ARN) that identifies the Auto Scaling group, or the Auto Scaling group name.

See:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ecs-capacityprovider-autoscalinggroupprovider.html#cfn-ecs-capacityprovider-autoscalinggroupprovider-autoscalinggrouparn

managed_draining

The managed draining option for the Auto Scaling group capacity provider.

When you enable this, Amazon ECS manages and gracefully drains the EC2 container instances that are in the Auto Scaling group capacity provider.

See:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ecs-capacityprovider-autoscalinggroupprovider.html#cfn-ecs-capacityprovider-autoscalinggroupprovider-manageddraining

managed_scaling

The managed scaling settings for the Auto Scaling group capacity provider.

See:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ecs-capacityprovider-autoscalinggroupprovider.html#cfn-ecs-capacityprovider-autoscalinggroupprovider-managedscaling

managed_termination_protection

The managed termination protection setting to use for the Auto Scaling group capacity provider.

This determines whether the Auto Scaling group has managed termination protection. The default is off. .. epigraph:

When using managed termination protection, managed scaling must also be used otherwise managed termination protection doesn't work.

When managed termination protection is on, Amazon ECS prevents the Amazon EC2 instances in an Auto Scaling group that contain tasks from being terminated during a scale-in action. The Auto Scaling group and each instance in the Auto Scaling group must have instance protection from scale-in actions on as well. For more information, see Instance Protection in the AWS Auto Scaling User Guide .

When managed termination protection is off, your Amazon EC2 instances aren’t protected from termination when the Auto Scaling group scales in.

See:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ecs-capacityprovider-autoscalinggroupprovider.html#cfn-ecs-capacityprovider-autoscalinggroupprovider-managedterminationprotection

ManagedScalingProperty

class CfnCapacityProvider.ManagedScalingProperty(*, instance_warmup_period=None, maximum_scaling_step_size=None, minimum_scaling_step_size=None, status=None, target_capacity=None)

Bases: object

The managed scaling settings for the Auto Scaling group capacity provider.

When managed scaling is turned on, Amazon ECS manages the scale-in and scale-out actions of the Auto Scaling group. Amazon ECS manages a target tracking scaling policy using an Amazon ECS managed CloudWatch metric with the specified targetCapacity value as the target value for the metric. For more information, see Using managed scaling in the Amazon Elastic Container Service Developer Guide .

If managed scaling is off, the user must manage the scaling of the Auto Scaling group.

Parameters:

instance_warmup_period (Union[int, float, None]) – The period of time, in seconds, after a newly launched Amazon EC2 instance can contribute to CloudWatch metrics for Auto Scaling group. If this parameter is omitted, the default value of 300 seconds is used.
maximum_scaling_step_size (Union[int, float, None]) – The maximum number of Amazon EC2 instances that Amazon ECS will scale out at one time. If this parameter is omitted, the default value of 10000 is used.
minimum_scaling_step_size (Union[int, float, None]) – The minimum number of Amazon EC2 instances that Amazon ECS will scale out at one time. The scale in process is not affected by this parameter If this parameter is omitted, the default value of 1 is used. When additional capacity is required, Amazon ECS will scale up the minimum scaling step size even if the actual demand is less than the minimum scaling step size. If you use a capacity provider with an Auto Scaling group configured with more than one Amazon EC2 instance type or Availability Zone, Amazon ECS will scale up by the exact minimum scaling step size value and will ignore both the maximum scaling step size as well as the capacity demand.
status (Optional[str]) – Determines whether to use managed scaling for the capacity provider.
target_capacity (Union[int, float, None]) – The target capacity utilization as a percentage for the capacity provider. The specified value must be greater than 0 and less than or equal to 100 . For example, if you want the capacity provider to maintain 10% spare capacity, then that means the utilization is 90%, so use a targetCapacity of 90 . The default value of 100 percent results in the Amazon EC2 instances in your Auto Scaling group being completely used.
