I have openstack deployed by openstack-helm. Sometimes my openstack cli is failed.

The error msg is:

Failed to discover available identity versions when contacting http://[redacted]:30500/v3. Attempting to parse version from URL.

Unable to establish connection to http://[redacted]:30500/v3/auth/tokens: HTTPConnectionPool(host='[redacted]', port=30500): Max retries exceeded with url: /v3/auth/tokens (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f95da0db510>: Failed to establish a new connection: [Errno 111] Connection refused',))

I used nodeport instead of local domain. but I think it is not related with my issue.

Anyway at that time, I found that kubernetes endpoints of openstack service and mariadb were disappeared and it appeared again after 1-2 minutes.

How can I keep always openstack services k8s endpoints?

Thanks in advance.
