CfnAccessEntry

class aws_cdk.aws_eks.CfnAccessEntry(scope, id, *, cluster_name, principal_arn, access_policies=None, kubernetes_groups=None, tags=None, type=None, username=None)

Bases: CfnResource

Creates an access entry.

An access entry allows an IAM principal to access your cluster. Access entries can replace the need to maintain entries in the aws-auth ConfigMap for authentication. You have the following options for authorizing an IAM principal to access Kubernetes objects on your cluster: Kubernetes role-based access control (RBAC), Amazon EKS, or both. Kubernetes RBAC authorization requires you to create and manage Kubernetes Role , ClusterRole , RoleBinding , and ClusterRoleBinding objects, in addition to managing access entries. If you use Amazon EKS authorization exclusively, you don’t need to create and manage Kubernetes Role , ClusterRole , RoleBinding , and ClusterRoleBinding objects.

For more information about access entries, see Access entries in the Amazon EKS User Guide .

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_eks as eks

cfn_access_entry = eks.CfnAccessEntry(self, "MyCfnAccessEntry",
    cluster_name="clusterName",
    principal_arn="principalArn",

    # the properties below are optional
    access_policies=[eks.CfnAccessEntry.AccessPolicyProperty(
        access_scope=eks.CfnAccessEntry.AccessScopeProperty(
            type="type",

            # the properties below are optional
            namespaces=["namespaces"]
        ),
        policy_arn="policyArn"
    )],
    kubernetes_groups=["kubernetesGroups"],
    tags=[CfnTag(
        key="key",
        value="value"
    )],
    type="type",
    username="username"
)

Parameters:

scope (Construct) – Scope in which this resource is defined.
id (str) – Construct identifier for this resource (unique in its scope).
cluster_name (str) – The name of your cluster.
principal_arn (str) – The ARN of the IAM principal for the AccessEntry . You can specify one ARN for each access entry. You can’t specify the same ARN in more than one access entry. This value can’t be changed after access entry creation. The valid principals differ depending on the type of the access entry in the type field. The only valid ARN is IAM roles for the types of access entries for nodes: `` `` . You can use every IAM principal type for STANDARD access entries. You can’t use the STS session principal type with access entries because this is a temporary principal for each session and not a permanent identity that can be assigned permissions. IAM best practices recommend using IAM roles with temporary credentials, rather than IAM users with long-term credentials.
access_policies (Union[IResolvable, Sequence[Union[IResolvable, AccessPolicyProperty, Dict[str, Any]]], None]) – The access policies to associate to the access entry.
kubernetes_groups (Optional[Sequence[str]]) – The value for name that you’ve specified for kind: Group as a subject in a Kubernetes RoleBinding or ClusterRoleBinding object. Amazon EKS doesn’t confirm that the value for name exists in any bindings on your cluster. You can specify one or more names. Kubernetes authorizes the principalArn of the access entry to access any cluster objects that you’ve specified in a Kubernetes Role or ClusterRole object that is also specified in a binding’s roleRef . For more information about creating Kubernetes RoleBinding , ClusterRoleBinding , Role , or ClusterRole objects, see Using RBAC Authorization in the Kubernetes documentation . If you want Amazon EKS to authorize the principalArn (instead of, or in addition to Kubernetes authorizing the principalArn ), you can associate one or more access policies to the access entry using AssociateAccessPolicy . If you associate any access policies, the principalARN has all permissions assigned in the associated access policies and all permissions in any Kubernetes Role or ClusterRole objects that the group names are bound to.
tags (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – Metadata that assists with categorization and organization. Each tag consists of a key and an optional value. You define both. Tags don’t propagate to any other cluster or AWS resources.
type (Optional[str]) – The type of the new access entry. Valid values are Standard , FARGATE_LINUX , EC2_LINUX , and EC2_WINDOWS . If the principalArn is for an IAM role that’s used for self-managed Amazon EC2 nodes, specify EC2_LINUX or EC2_WINDOWS . Amazon EKS grants the necessary permissions to the node for you. If the principalArn is for any other purpose, specify STANDARD . If you don’t specify a value, Amazon EKS sets the value to STANDARD . It’s unnecessary to create access entries for IAM roles used with Fargate profiles or managed Amazon EC2 nodes, because Amazon EKS creates entries in the aws-auth ConfigMap for the roles. You can’t change this value once you’ve created the access entry. If you set the value to EC2_LINUX or EC2_WINDOWS , you can’t specify values for kubernetesGroups , or associate an AccessPolicy to the access entry.
username (Optional[str]) – The username to authenticate to Kubernetes with. We recommend not specifying a username and letting Amazon EKS specify it for you. For more information about the value Amazon EKS specifies for you, or constraints before specifying your own username, see Creating access entries in the Amazon EKS User Guide .

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

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.

AccessPolicyProperty

class CfnAccessEntry.AccessPolicyProperty(*, access_scope, policy_arn)

Bases: object

An access policy includes permissions that allow Amazon EKS to authorize an IAM principal to work with Kubernetes objects on your cluster.

The policies are managed by Amazon EKS, but they’re not IAM policies. You can’t view the permissions in the policies using the API. The permissions for many of the policies are similar to the Kubernetes cluster-admin , admin , edit , and view cluster roles. For more information about these cluster roles, see User-facing roles in the Kubernetes documentation. To view the contents of the policies, see Access policy permissions in the Amazon EKS User Guide .

Parameters:

access_scope (Union[IResolvable, AccessScopeProperty, Dict[str, Any]]) – The scope of an AccessPolicy that’s associated to an AccessEntry .
policy_arn (str) – The ARN of the access policy.
