Unable to Increase Default Root Device from AWS Launch Template

[asafpelegcodes]

Terraform v0.11.7
+ provider.aws v1.22.0

I'm testing out creating Launch Templates with aws_launch_template and I'm unable to reproduce a result that I achieved manually through the GUI. Using the GUI I was able to override the default block device for the AMI listed below (see describe image) and give it a larger volume. The GUI shows "Default" for this (see image).

However, when I try & recreate the same thing with terraform it doesn't seem to be possible because even if I omit delete_on_termination & encrypted terraform provides default values for this. When I create a spot request I get errors from the console saying the encrypted flag cannot be specified since device /dev/xvda has a snapshot specified.

aws ec2 describe-images --image-ids ami-04351e12

Here is the sample terraform config I am working with.

resource "aws_launch_template" "ecs-cluster-default" {
...

  block_device_mappings {
    device_name = "/dev/xvda"
    ebs {
      volume_size = 10
      volume_type = "gp2"
      delete_on_termination = "true"
      encrypted = "false"
    }
  }

  image_id = "ami-04351e12"
}

Expected Behavior

I should be able to omit encrypted & delete_on_termination from the block/ebs block and terraform will omit the values to the API and AWS will use Defaults for these blocks.

Actual Behavior

Terraform forces the value when it's omitted to a default value it has stored internally resulting in being unable to overwrite the root device.

This appears to be a duplicate of #4553.

I agree looks similar

The fix for this has been merged into master and will release with version 1.34.0 of the AWS provider, likely later today.
