To get a high-level view of how Amazon EMR on EKS and other AWS services work with most IAM features, see AWS services that work with IAM in the IAM User Guide.
Identity-based policies for Amazon EMR on EKS
Supports identity-based policies: Yes
Identity-based policies are JSON permissions policy documents that you can attach to an identity, such as an IAM user, group of users, or role. These policies control what actions users and roles can perform, on which resources, and under what conditions. To learn how to create an identity-based policy, see Define custom IAM permissions with customer managed policies in the IAM User Guide.
With IAM identity-based policies, you can specify allowed or denied actions and resources as well as the conditions under which actions are allowed or denied. To learn about all of the elements that you can use in a JSON policy, see IAM JSON policy elements reference in the IAM User Guide.

Resource-based policies within Amazon EMR on EKS
Supports resource-based policies: No
Resource-based policies are JSON policy documents that you attach to a resource. Examples of resource-based policies are IAM role trust policies and Amazon S3 bucket policies. In services that support resource-based policies, service administrators can use them to control access to a specific resource. For the resource where the policy is attached, the policy defines what actions a specified principal can perform on that resource and under what conditions. You must specify a principal in a resource-based policy. Principals can include accounts, users, roles, federated users, or AWS services.
To enable cross-account access, you can specify an entire account or IAM entities in another account as the principal in a resource-based policy. For more information, see Cross account resource access in IAM in the IAM User Guide.
Policy actions for Amazon EMR on EKS
Supports policy actions: Yes
Administrators can use AWS JSON policies to specify who has access to what. That is, which principal can perform actions on what resources, and under what conditions.
The Action
element of a JSON policy describes the
actions that you can use to allow or deny access in a policy. Include actions in a policy to grant permissions to perform the associated operation.
To see a list of Amazon EMR on EKS actions, see Actions, resources, and condition keys for Amazon EMR on EKS in the Service Authorization Reference.
Policy actions in Amazon EMR on EKS use the following prefix before the action:
emr-containers
To specify multiple actions in a single statement, separate them with commas.
"Action": [ "emr-containers:
action1
", "emr-containers:action2
" ]

Policy resources for Amazon EMR on EKS
Supports policy resources: Yes
Administrators can use AWS JSON policies to specify who has access to what. That is, which principal can perform actions on what resources, and under what conditions.
The Resource
JSON policy element specifies the object or objects to which the action applies. As a best practice, specify a resource using its Amazon Resource Name (ARN). For actions that don't support resource-level permissions, use a wildcard (*) to indicate that the statement applies to all resources.
"Resource": "*"
To see a list of Amazon EMR on EKS resource types and their ARNs, see Resources defined by Amazon EMR on EKS in the Service Authorization Reference. To learn which actions you can specify the ARN of each resource, see Actions, resources, and condition keys for Amazon EMR on EKS.
To view examples of Amazon EMR on EKS identity-based policies, see Identity-based policy examples for Amazon EMR on EKS.
Policy condition keys for Amazon EMR on EKS
Supports service-specific policy condition keys: Yes
Administrators can use AWS JSON policies to specify who has access to what. That is, which principal can perform actions on what resources, and under what conditions.
The Condition
element specifies when statements execute based on defined criteria. You can create conditional expressions that use condition
operators, such as equals or less than, to match the condition in the
policy with values in the request. To see all AWS global
condition keys, see AWS global condition context keys in the
IAM User Guide.
To see a list of Amazon EMR on EKS condition keys and to learn which actions and resources you can use a condition key, see Actions, resources, and condition keys for Amazon EMR on EKS in the Service Authorization Reference.
To view examples of Amazon EMR on EKS identity-based policies, see Identity-based policy examples for Amazon EMR on EKS.
Access control lists (ACLs) in Amazon EMR on EKS
Supports ACLs: No
Access control lists (ACLs) control which principals (account members, users, or roles) have permissions to access a resource. ACLs are similar to resource-based policies, although they do not use the JSON policy document format.
Attribute-based access control (ABAC) with Amazon EMR on EKS
Supports ABAC (tags in policies) | Yes |
Attribute-based access control (ABAC) is an authorization strategy that defines permissions based on attributes called tags. You can attach tags to IAM entities and AWS resources, then design ABAC policies to allow operations when the principal's tag matches the tag on the resource.
To control access based on tags, you provide tag information in the condition element of a policy using the aws:ResourceTag/
,
key-name
aws:RequestTag/
, or key-name
aws:TagKeys
condition keys.
If a service supports all three condition keys for every resource type, then the value is Yes for the service. If a service supports all three condition keys for only some resource types, then the value is Partial.
For more information about ABAC, see Define permissions with ABAC authorization in the IAM User Guide. To view a tutorial with steps for setting up ABAC, see Use attribute-based access control (ABAC) in the IAM User Guide.
Using Temporary credentials with Amazon EMR on EKS
Supports temporary credentials: Yes
Temporary credentials provide short-term access to AWS resources and are automatically created when you use federation or switch roles. AWS recommends that you dynamically generate temporary credentials instead of using long-term access keys. For more information, see Temporary security credentials in IAM and AWS services that work with IAM in the IAM User Guide.
Cross-service principal permissions for Amazon EMR on EKS
Supports forward access sessions (FAS): Yes
Forward access sessions (FAS) use the permissions of the principal calling an AWS service, combined with the requesting AWS service to make requests to downstream services. For policy details when making FAS requests, see Forward access sessions.
Service roles for Amazon EMR on EKS
Supports service roles | No |
Service-linked roles for Amazon EMR on EKS
Supports service-linked roles | Yes |
For details about creating or managing service-linked roles, see AWS services
that work with IAM. Find a service in the table that includes a
Yes
in the Service-linked role column. Choose the
Yes link to view the service-linked role documentation for that
service.
