thank you for your response , actually for the authentication options i use the exactly same admin-openrpc as mentioned in the documentation [https://docs.openstack.org/mitaka/install-guide-ubuntu/keystone-openrc.html#using-the-scripts (https://docs.openstack.org/mitaka/ins...)] and verify usernane and password from the horizon dashbord

From https://docs.docker.com/machine/drive..., it appears that docker-machine uses TENANT instead of PROJECT. Could that be at the root of the problem?

i aded the option OS_TENANT_NAME=default instead of OS_TENANT_PROJECT=default in vaine. i checked nova-compute.log and there is the error bellow

ERROR oslo.messaging._drivers.impl_rabbit [-] AMQP server on controller:5672 is unreachable: [Errno 113] EHOSTUNREACH. Trying again in 8 seconds.

This can be a temporary situation when starting up, or a permanent problem. It's not clear to me how it affects authentication, but if it's a permanent problem, it needs fixing anyway. Is port 5672 on controller reachable?

By the way, can you successfully run any openstack commands like openstack token issue or openstack network agent list?

yes openstack commands work fine , i even installed the nova-docker so i have docker as hypervisonr and i succesfully created images and lunched instances. but docker-machine command doesn't work. is it because the docker-machine can't reach controller? but i run the command on the controller node!!

probably it's network configuration issus? my controller's ip is :192.168.1.250 , my compute's ip is : 192.168.1.251 , i created a provider network as here : https://docs.openstack.org/mitaka/install-guide-ubuntu/launch-instance-networks-provider.html (https://docs.openstack.org/mitaka/ins...) and it's subnet associated to 203.0.113.0/24

IP address for docker0: 172.17.0.1 , in the keystone log i found this error Authorization failed. The request you have made requires authentication. from 127.0.0.1 , why it mention 127.0.0.1 ip !!

Do a brute-force search for 127.0.0.1 and localhost on all config files.

i did a search for the 127.0.0.1 ip , here is the result uploded here : [http://textuploader.com/d0wn5] any idea?

I'd say /etc/hosts:127.0.0.1 controller is at the origin of your problems. Replace it by the correct address and try again.

same error with a waring : `{"error": {"message": "The request you have made requires authentication.", "code": 401, "title": "Unauthorized"}} Post https://notify.bugsnag.com/: dial tcp: lookup http://notify.bugsnag.com on [::1]:53: read udp [::1]:52980->[::1]:53: read: connection refused]
