No, it is a different issue. I am still stuck when creating a cluster (swarm or kubernetes) because of this error that i find in cloud-init log.
  • requests.exceptions.ConnectionError: HTTPConnectionPool(host='10.60.60.10', port=5000): Max retries exceeded with url: /v3/auth/tokens (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f02f57321d0>: Failed to establish a new connection: [Errno 110] Connection timed out',))
Swarm Instance try to open connection to 10.60.60.10 which is my management IP address on OpenStack.  But it cannot (by design it cannot, I try to curl manual to 10.60.60.10 and error). When curl to 10.61.61.10 which is my floating IP and external IP for OpenStack cluster, it works.

Do you know how to change the URL that installed inside the cloud-init?

Hi Zufar, Yes it is possible but if you want persistent storage you need cinder.
Magnum can use cinder.

I did not get this error but in magnum.conf I have the following section:
[cinder_client]
