Example:

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

cfn_addon = eks_legacy.CfnAddon(self, "MyCfnAddon",

    service_account_role_arn="serviceAccountRoleArn",
    tags=[CfnTag(
        key="key",
        value="value"
    )]
)

Create a new AWS::EKS::Addon.

Parameters

scope (Construct) –
- scope in which this resource is defined.
id (str) –
- scoped id of the resource.
addon_name (str) – The name of the add-on.
cluster_name (str) – The name of the cluster.
addon_version (Optional[str]) – The version of the add-on.
configuration_values (Optional[str]) – The configuration values that you provided.
preserve_on_delete (Union[bool, IResolvable, None]) – Specifying this option preserves the add-on software on your cluster but Amazon EKS stops managing any settings for the add-on. If an IAM account is associated with the add-on, it isn’t removed.
resolve_conflicts (Optional[str]) – How to resolve field value conflicts for an Amazon EKS add-on. Conflicts are handled based on the value you choose: - None – If the self-managed version of the add-on is installed on your cluster, Amazon EKS doesn’t change the value. Creation of the add-on might fail. - Overwrite – If the self-managed version of the add-on is installed on your cluster and the Amazon EKS default value is different than the existing value, Amazon EKS changes the value to the Amazon EKS default value. - Preserve – Not supported. You can set this value when updating an add-on though. For more information, see UpdateAddon . If you don’t currently have the self-managed version of the add-on installed on your cluster, the Amazon EKS add-on is installed. Amazon EKS sets all values to default values, regardless of the option that you specify.
service_account_role_arn (Optional[str]) – The Amazon Resource Name (ARN) of an existing IAM role to bind to the add-on’s service account. The role must be assigned the IAM permissions required by the add-on. If you don’t specify an existing IAM role, then the add-on uses the permissions assigned to the node IAM role. For more information, see Amazon EKS node IAM role in the Amazon EKS User Guide . .. epigraph:: To specify an existing IAM role, you must have an IAM OpenID Connect (OIDC) provider created for your cluster. For more information, see Enabling IAM roles for service accounts on your cluster in the Amazon EKS User Guide .
tags (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – The metadata that you apply to the add-on to assist with categorization and organization. Each tag consists of a key and an optional value, both of which you define. Add-on tags do not propagate to any other resources associated with the cluster.

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_depends_on(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_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 intermdediate 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).

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 resoure, please consult that specific resource’s documentation.

Return type

None

get_att(attribute_name)

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.
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

override_logical_id(new_logical_id)

Overrides the auto-generated logical ID with a specific ID.

Parameters: new_logical_id (str) – The new logical ID to use for this stack element.
Return type: None

to_string()

Returns a string representation of this construct.

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

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 }).

resolve_conflicts

How to resolve field value conflicts for an Amazon EKS add-on.

Conflicts are handled based on the value you choose:

None – If the self-managed version of the add-on is installed on your cluster, Amazon EKS doesn’t change the value. Creation of the add-on might fail.
Overwrite – If the self-managed version of the add-on is installed on your cluster and the Amazon EKS default value is different than the existing value, Amazon EKS changes the value to the Amazon EKS default value.
Preserve – Not supported. You can set this value when updating an add-on though. For more information, see UpdateAddon .

If you don’t currently have the self-managed version of the add-on installed on your cluster, the Amazon EKS add-on is installed. Amazon EKS sets all values to default values, regardless of the option that you specify.
