我最近安装了devstack来使用Openstack API。
关注Openstack API Quickstart我运行以下命令来获取身份验证令牌：
curl -d '{"auth":{"passwordCredentials":{"username": "admin", "password": "openstack"}, "tenantId": "793e8386d75f47b1bd078a3c0ddd9a49"}}' -H "Content-type: application/json" http://192.168.1.20:5000/v2.0/tokens
然后我得到回报：

我注意到，从JSON元数据输出中它返回“is_admin”：0 。
为什么？
我期待Keystone返回1.
