    Attaches a Managed IAM Policy to user(s), role(s), and/or group(s)

    !> WARNING: The aws.iam.PolicyAttachment resource creates exclusive attachments of IAM policies. Across the entire AWS account, all of the users/roles/groups to which a single policy is attached must be declared by a single aws.iam.PolicyAttachment resource. This means that even any users/roles/groups that have the attached policy via any other mechanism (including other resources managed by this provider) will have that attached policy revoked by this resource. Consider aws.iam.RolePolicyAttachment, aws.iam.UserPolicyAttachment, or aws.iam.GroupPolicyAttachment instead. These resources do not enforce exclusive attachment of an IAM policy.

    NOTE: The usage of this resource conflicts with the aws.iam.GroupPolicyAttachment, aws.iam.RolePolicyAttachment, and aws.iam.UserPolicyAttachment resources and will permanently show a difference if both are defined.

    NOTE: For a given role, this resource is incompatible with using the aws.iam.Role resource managed_policy_arns argument. When using that argument and this resource, both will attempt to manage the role’s managed policy attachments and the provider will show a permanent difference.

    NOTE: To ensure Pulumi correctly manages dependencies during updates, use a reference to the IAM resource when defining the policy_arn for aws.iam.PolicyAttachment, rather than constructing the ARN directly. For example, use policy_arn = aws_iam_policy.example.arn instead of policy_arn = "arn:aws:iam::${data.aws_caller_identity.current.account_id}:policy/Example". Failing to do so may lead to errors like DeleteConflict: Cannot delete a policy attached to entities or NoSuchEntity.

    Example Usage

    import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

const user = new aws.iam.User("user", {name: "test-user"});

    PolicyAttachment Resource Properties

    To learn more about resource properties and how to use them, see Inputs and Outputs in the Architecture and Concepts docs.

    Inputs

    In Python, inputs that are objects can be passed either as argument classes or as dictionary literals.

    The PolicyAttachment resource accepts the following input properties:

    PolicyArn string
    ARN of the policy you want to apply. Typically this should be a reference to the ARN of another resource to ensure dependency ordering, such as aws_iam_policy.example.arn.
    Groups List<string>
    Group(s) the policy should be applied to.
    Name string
    Name of the attachment. This cannot be an empty string.
    Roles List<string>
    Role(s) the policy should be applied to.
    Users List<string>
    User(s) the policy should be applied to.
    PolicyArn string
    ARN of the policy you want to apply. Typically this should be a reference to the ARN of another resource to ensure dependency ordering, such as aws_iam_policy.example.arn.
    Groups []interface{}
    Group(s) the policy should be applied to.
    Name string
    Name of the attachment. This cannot be an empty string.
    Roles []interface{}
    Role(s) the policy should be applied to.
    Users []interface{}
    User(s) the policy should be applied to.
    policyArn String
    ARN of the policy you want to apply. Typically this should be a reference to the ARN of another resource to ensure dependency ordering, such as aws_iam_policy.example.arn.

    Role(s) the policy should be applied to.
    users List<String>
    User(s) the policy should be applied to.
    policyArn ARN
    ARN of the policy you want to apply. Typically this should be a reference to the ARN of another resource to ensure dependency ordering, such as aws_iam_policy.example.arn.
    groups (string | Group)[]
    Group(s) the policy should be applied to.
    name string
    Name of the attachment. This cannot be an empty string.
    roles (string | Role)[]
    Role(s) the policy should be applied to.
    users (string | User)[]
    User(s) the policy should be applied to.
    policy_arn str
    ARN of the policy you want to apply. Typically this should be a reference to the ARN of another resource to ensure dependency ordering, such as aws_iam_policy.example.arn.

    Outputs

    All input properties are implicitly available as output properties. Additionally, the PolicyAttachment resource produces the following output properties:

    Id string
    The provider-assigned unique ID for this managed resource.
    Id string
    The provider-assigned unique ID for this managed resource.
    id String

    id str
    The provider-assigned unique ID for this managed resource.
    id String
    The provider-assigned unique ID for this managed resource.
