EC2 volume: how do I set it so that it WILL delete on termination?

I have an EC2 instance that I'd like to take a snapshot of, to use as an AMI for future spot instances. Because of the way I created volume for this instance, it is currently set to not delete upon termination.
I want it to delete on termination, so that I can use it for spot instances and not have residual volumes hanging around needing manual deletion.

I've combed AWS manual, stack exchange, google, etc and I can only find references to a 'delete on termination' flag, but no explanation of how to use it.

You can use AWS-CLI to do this:

The simplest way is to use modify-instance-attribute subcommand provided by aws ec2 command.

aws ec2 modify-instance-attribute --instance-id i-123ab12f --block-device-mappings file://~/some.json

Content of file some.json should be:

[
    {
    "DeviceName": "/dev/sda1",
    "Ebs": {
      "DeleteOnTermination": true
      }
    }
]

Shameless Plug: If you regularly work with AWS, take this highly engaging AWS Quiz to check your AWS knowledge.

Taking on what everybody else said, one line and without JSON encoding and ugly escapes:

modify-instance-attribute --instance-id $ID --block-device-mappings 'DeviceName=/dev/sdf,Ebs={DeleteOnTermination=true}'

Taking on what @akshar wrote, you can have it all in the same line, without the need for an additional json file:

 aws ec2 modify-instance-attribute --instance-id i-123abc45 --block-device-mappings "[{\"DeviceName\": \"/dev/sdf\",\"Ebs\":{\"DeleteOnTermination\":true}}]"

where /dev/sdf is the mount point in your instance
