Amazon EC2: Attach or detach Amazon EBS volumes to EC2 instances based on tags

Focus mode
Amazon EC2: Attach or detach Amazon EBS volumes to EC2 instances based on tags - AWS Identity and Access Management

This example shows how you might create an identity-based policy that allows EBS volume owners to attach or detach their EBS volumes defined using the tag VolumeUser to EC2 instances that are tagged as development instances (Department=Development). This policy grants the permissions necessary to complete this action programmatically from the AWS API or AWS CLI. 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.

For more information about creating IAM policies to control access to Amazon EC2 resources, see Controlling Access to Amazon EC2 Resources in the Amazon EC2 User Guide.
