aws_volume_attachment

Provides an AWS EBS Volume Attachment as a top level resource, to attach and detach volumes from AWS Instances.

~> NOTE on EBS block devices: If you use ebs_block_device on an aws_instance, Terraform will assume management over the full set of non-root EBS block devices for the instance, and treats additional block devices as drift. For this reason, ebs_block_device cannot be mixed with external aws_ebs_volume + aws_ebs_volume_attachment resources for a given instance.

Example Usage

resource "aws_volume_attachment" "ebs_att" {
  device_name = "/dev/sdh"
  volume_id = "${aws_ebs_volume.example.id}"
  instance_id = "${aws_instance.web.id}"
}

resource "aws_instance" "web" {
  ami = "ami-21f78e11"
  availability_zone = "us-west-2a"
  instance_type = "t1.micro"
  tags {
    Name = "HelloWorld"
  }
}

resource "aws_ebs_volume" "example" {
  availability_zone = "us-west-2a"
  size = 1
}

Argument Reference

The following arguments are supported:

• device_name - (Required) The device name to expose to the instance (for example, /dev/sdh or xvdh)
• instance_id - (Required) ID of the Instance to attach to
• volume_id - (Required) ID of the Volume to be attached
• force_detach - (Optional, Boolean) Set to true if you want to force the volume to detach. Useful if previous attempts failed, but use this option only as a last resort, as this can result in data loss. See Detaching an Amazon EBS Volume from an Instance for more information.

Attributes Reference

• device_name - The device name exposed to the instance
• instance_id - ID of the Instance
• volume_id - ID of the Volume
