当我试图为juju定义OpenStack云时，无法验证keystone端点

Question

我正试图为聚居定义一个OpenStack云。为此，我首先使用local.conf文件中的以下配置部署了Dev堆栈：

$ cat local.conf | grep -v "#" | grep -v "^$"
[[local|localrc]]
ADMIN_PASSWORD=admin
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
HOST_IP=172.29.21.181
FLOATING_RANGE=172.29.20.1/22
Q_FLOATING_ALLOCATION_POOL=start=172.29.21.182,end=172.29.21.184
PUBLIC_NETWORK_GATEWAY=172.29.21.181
ENABLED_SERVICES+=,tls-proxy
ENABLED_SERVICES+=,g-api,g-reg
LOGFILE=$DEST/logs/stack.sh.log
LOGDAYS=2
SWIFT_HASH=66a3d6b56c1f479c8b4e70ab5c2000f5
SWIFT_REPLICAS=1
SWIFT_DATA_DIR=$DEST/data

在成功部署之后，以下是端点：

$ openstack endpoint list

但是，当我尝试使用"juju“命令向juju添加云时(我遵循这个链接的指示：https://juju.is/docs/olm/openstack)，我得到以下错误：

$ juju add-cloud openstack
This operation can be applied to both a copy on this client and to the one on a controller.
No current controller was detected and there are no registered controllers on this client: either bootstrap one or register one.
Cloud Types
  lxd
  maas
  manual
  openstack
  vsphere

Select cloud type: openstack

Enter the API endpoint url for the cloud [https://172.29.21.181/identity]: https://172.29.21.181/identity
Can't validate endpoint: No Openstack server running at https://172.29.21.181/identity

Enter the API endpoint url for the cloud [https://172.29.21.181/identity]: https://172.29.21.181/identity/v3
Can't validate endpoint: No Openstack server running at https://172.29.21.181/identity/v3

Enter the API endpoint url for the cloud [https://172.29.21.181/identity]: http://172.29.21.181/identity
Can't validate endpoint: No Openstack server running at http://172.29.21.181/identity

Enter the API endpoint url for the cloud [https://172.29.21.181/identity]: https://172.29.21.181:5000/v3
Can't validate endpoint: No Openstack server running at https://172.29.21.181:5000/v3

我可以卷曲网址：

$ curl https://172.29.21.181/identity
{"versions": {"values": [{"id": "v3.14", "status": "stable", "updated": "2020-04-07T00:00:00Z", "links": [{"rel": "self", "href": "https://172.29.21.181/identity/v3/"}], "media-types": [{"base": "application/json", "type": "application/vnd.openstack.identity-v3+json"}]}]}}

我可以连接到Keystone正在监听的端口：

$ nc -vz 172.29.21.181 5000
Connection to 172.29.21.181 5000 port [tcp/*] succeeded!

我把no_proxy=127.0.0.1，localhost,172.29.21.181和NO_PROXY=127.0.0.1，localhost,172.29.21.181作为环境变量，因为在互联网上搜索解决方案，我知道它也许可以解决我的问题。但没起作用。除了这个云之外，我还通过Openstack部署了另一个云。在这个云中，我没有遇到这个错误，唯一的区别是url是https://{HOST_IP}:5000/v3。如果任何人有任何想法，这将是非常有帮助的，谢谢。

Answer 1

我已经找到了绕过这个错误的方法，但我不知道确切的原因。我修改了OS_AUTH_URL环境变量，以“/v3”结尾：

$ unset OS_AUTH_URL
$ export OS_AUTH_URL=https://172.29.21.181/identity/v3

现在，在运行“”时将其作为建议值使用后，在运行“”时不会出现错误。我想当您手动输入url时，juju检查它的有效性，并可能由于某种代码原因而失败。跳过了这个检查之后，我猜“”命令将直接使用以“/v3”结尾的url，这是正确的并且工作的。

现在，我得到以下错误：

$ juju bootstrap openstack --verbose
Adding contents of "/opt/stack/.local/share/juju/ssh/juju_id_rsa.pub" to authorized-keys
Creating Juju controller "openstack-regionone" on openstack/RegionOne
Loading image metadata
ERROR failed to bootstrap model: no image metadata found

但是我想我只需要在我的部署中添加Swift，然后按照以下链接中的说明操作：https://juju.is/docs/olm/cloud-image-metadata
