Comment 5 for bug 1663076

Pre-Requisites for execution of Docker test suite:
1. All the contrail controller hosts and openstack controller hosts should be reachable from the Docker
2. Unreachable computes will be skipped
3. Without the right testbed.py matching the actual contrail cluster, the DCTS scripts will fail.
4. Environment files ‘astute.yaml’ and ‘openrc’ are mandatory files to generate ‘testbed.py’
5. All the service endpoints, both contrail and openstack, should be reachable from the Docker (In case of REST services via VIP)
6. If keystone endpoints are name based, then the names should be resolvable from the Docker
neutron_username specified in testbed.py is the same as found in /etc/contrail/contrail-keystone-auth.conf admin_user
