IAM: Add a specific tag with specific values

This example shows how you might create an identity-based policy that allows adding only the tag key CostCenter and either the tag value A-123 or the tag value B-456 to any IAM user or role. You can use this policy to limit tagging to a specific tag key and set of tag values. This policy defines permissions for programmatic and console access. To use this policy, replace the italicized placeholder text in the example policy with your own information. Then, follow the directions in create a policy or edit a policy.

The ConsoleDisplay statement allows the viewing of tags for all users and roles in your account.

The first condition in the AddTag statement uses the StringEquals condition operator. The condition returns true if the request includes the CostCenter tag key with one of the listed tag values.

The second condition uses the ForAllValues:StringEquals condition operator. The condition returns true if all of the tag keys in the request match the key in the policy. This means that the only tag key in the request must be CostCenter. For more information about using ForAllValues, see Multivalued context keys.
