For this reason, `ebs_block_device` cannot be mixed with external `aws_ebs_volume` + `aws_ebs_volume_attachment` resources for a given instance. 15 16 ## Example Usage 17 18 ``` 19 resource "aws_volume_attachment" "ebs_att" { 20 device_name = "/dev/sdh" 21 volume_id = "${aws_ebs_volume.example.id}" 22 instance_id = "${aws_instance.web.id}" 23 } 24 25 resource "aws_instance" "web" { 26 ami = "ami-21f78e11" 27 availability_zone = "us-west-2a" 28 instance_type = "t1.micro" 29 tags { 30 Name = "HelloWorld" 31 } 32 } 33 34 resource "aws_ebs_volume" "example" { 35 availability_zone = "us-west-2a" 36 size = 1 37 } 38 ``` 39 40 ## Argument Reference 41 42 The following arguments are supported: 43 44 * `device_name` - (Required) The device name to expose to the instance (for 45 example, `/dev/sdh` or `xvdh`) 46 * `instance_id` - (Required) ID of the Instance to attach to 47 * `volume_id` - (Required) ID of the Volume to be attached 48 * `force_detach` - (Optional, Boolean) Set to `true` if you want to force the 49 volume to detach. Useful if previous attempts failed, but use this option only 50 as a last resort, as this can result in **data loss**. See 51 [Detaching an Amazon EBS Volume from an Instance][1] for more information. 52 * `skip_destroy` - (Optional, Boolean) Set this to true if you do not wish 53 to detach the volume from the instance to which it is attached at destroy 54 time, and instead just remove the attachment from Terraform state. This is 55 useful when destroying an instance which has volumes created by some other 56 means attached. 57 58 ## Attributes Reference 59 60 * `device_name` - The device name exposed to the instance 61 * `instance_id` - ID of the Instance 62 * `volume_id` - ID of the Volume 63 64 [1]: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-detaching-volume.html
