bootstrap servers

root@yjwang0-stack-11:~# cd kolla-ansible/tools/
root@yjwang0-stack-11:~/kolla-ansible/tools# ./kolla-ansible -i ../../all-in-one bootstrap-servers

 

Do pre-deployment checks for hosts:

root@yjwang0-stack-11:~/kolla-ansible/tools# ./kolla-ansible -i ../../all-in-one prechecks

 

Finally proceed to actual OpenStack deployment:

root@yjwang0-stack-11:~/kolla-ansible/tools# ./kolla-ansible -i ../../all-in-one deploy

 

Check OpenStack Containers

root@yjwang0-stack-11:~# docker ps
CONTAINER ID   IMAGE                                                  COMMAND                  CREATED              STATUS                             PORTS     NAMES
