When a server is no longer necessary you can simply delete it. One REST call and the server is gone. You will need to add the server id number after /servers and you must use the DELETE method, as in:
$ curl -s -X DELETE -H "X-Auth-Token:999888777666" http://localhost:8774/v1.1/openstack/servers/3
The OpenStack Compute API server will not return a JSON object when the operation is successful, but it will return an error message when the server you are trying to delete does not exist:
{
"itemNotFound": {
"message": "The resource could not be found.",
"code": 404
}
}
