'openstack stack delete'

先拿到project id, 也被称为tenant id:

$ openstack project list --user cranuser8
+----------------------------------+-------+
| ID                               | Name  |
+----------------------------------+-------+
| 6bcb7e7677a5449196fd56565f68fc7f | cran8 |
+----------------------------------+-------+

然后拿到stack name:

$ openstack stack list --property tenant=6bcb7e7677a5449196fd56565f68fc7f --short
+--------------------------------------+--------------------------+----------------------------------+-----------------+
| ID                                   | Stack Name               | Project                          | Stack Status    |
+--------------------------------------+--------------------------+----------------------------------+-----------------+
| 6580a49e-d751-4737-baeb-cf9c16744ca2 | cranuser8_rcpautoinstall | 6bcb7e7677a5449196fd56565f68fc7f | CREATE_COMPLETE |
+--------------------------------------+--------------------------+----------------------------------+-----------------+

通常我们用下面命令来删除stack：

openstack stack delete cranuser8_rcpautoinstall 

但是，我们今天不这样做，我们来分析一下openstack stack delete这条命令背后做了什么？
首先，这条命令背后肯定是用到了openstack的restful api。我们可以先用--debug来看一下。

openstack --debug stack delete cranuser8_rcpautoinstall

然后我们用api来重现一下这条命令：

1 拿令牌

curl -i -d '
    {
        "auth": {
            "identity": {
                "methods": ["password"],
                "password": {
                    "user": {
                        "domain": {"name": "Default"},
                        "name": "cranuser8",
                        "password": "systeM!23"
                    }
                }
            }
        }
    }' -H "Content-type: application/json" "http://192.168.54.5:5000/v3/auth/tokens"

令牌在X-Subject-Token中：

HTTP/1.1 201 Created
...
X-Subject-Token: gAAAAABcY8MBRKLwy0cCuAADC926-SDw1tz1RWVG6LJkKWx22gkk5SPfby_oAJDRwtfvEXIXfWPVM_QT9WacmSH6J9W8CTw3_iyqldMDcDXTULfgh4pYZyqCrJBdrCimA4deamsleQRXRCLSZoRbvH7EBn_jhJySf-rLKiIwmiEGJOUcpOi03ZU

2 删掉stack

curl -g -i -L -X DELETE http://192.168.54.5:8004/v1/6bcb7e7677a5449196fd56565f68fc7f/stacks/cranuser8_rcpautoinstall -H "Accept: application/json" -H "X-Auth-Token: gAAAAABcY8MBRKLwy0cCuAADC926-SDw1tz1RWVG6LJkKWx22gkk5SPfby_oAJDRwtfvEXIXfWPVM_QT9WacmSH6J9W8CTw3_iyqldMDcDXTULfgh4pYZyqCrJBdrCimA4deamsleQRXRCLSZoRbvH7EBn_jhJySf-rLKiIwmiEGJOUcpOi03ZU"

通过下面命令可以看到删除已经开始了：

$ openstack stack list --property tenant=6bcb7e7677a5449196fd56565f68fc7f --short
