Hello,

my goal is to deploy openstack using kolla-ansible. I have four boards (GYGABYTE H310M A, i3 core, 32 GB RAM, 240GB SSD) connected via an ethernet switch. One baord is used as deployment environment and it is armed by Ubuntu desktop 18.04. The other boards, act like one controller, one compute and one networking board, each armed by Ubuntu server 18.04. Any board is using one NIC, with one dhcp address and per any board I have defined two vlans with static addresses, one used as network_interface (and api_interface), one used for neutron_external_interface (as defined in /etc/kolla/globals.yml file). I have followed installation instruction described in:

https://github.com/openstack/kolla-ansible/blob/master/doc/source/user/quickstart.rst (https://github.com/openstack/kolla-an...)

https://github.com/inc0/kolla-ansible-workshop/blob/master/chapter1.md (https://github.com/inc0/kolla-ansible...)

https://docs.openstack.org/project-deploy-guide/kolla-ansible/ocata/multinode.html (https://docs.openstack.org/project-de...)

https://docs.docker.com/install/linux/docker-ce/ubuntu/#prerequisites (https://docs.docker.com/install/linux...)

Any application, command, tool or script is up-to-date, so I´m using the very latest version. Now I´m able to run the following sequence with no errors:

sudo kolla-ansible -i ./multinode boostrap-servers

PLAY RECAP ************************

XX.YY.TT.157 : ok=38 changed=5 unreachable=0 failed=0
XX.YY.ZZ.198 : ok=38 changed=5 unreachable=0 failed=0
XX.YY.XX.243 : ok=38 changed=5 unreachable=0 failed=0

sudo kolla-ansible -i ./multinode prechecks

PLAY RECAP ************************

XX.YY.ZZ.198 : ok=75 changed=0 unreachable=0 failed=0
XX.YY.TT.243 : ok=32 changed=0 unreachable=0 failed=0

sudo kolla-ansible -i ./multinode pull

PLAY RECAP ************************

XX.YY.TT.157 : ok=13 changed=0 unreachable=0 failed=0
XX.YY.ZZ.198 : ok=37 changed=0 unreachable=0 failed=0
XX.YY.ZZ.243 : ok=19 changed=0 unreachable=0 failed=0
localhost : ok=18 changed=0 unreachable=0 failed=0

in that sequence, localhost is the deployment board, XX.YY.TT.157 is the networking, XX.YY.ZZ.198 is the controller and XX.YY.ZZ.243 is the compute. The docker registry is created in the delpoyment board, the localhost, that has address XX.YY.ZZ.167.

Now I'm a bit stuck on the latest phase, the deploy. In fact, if I use the command:

sudo kolla-ansible -i ./multinode deploy

the very first time fails with the following errore message:
