Creating Neutron database run once causing future deployments to fail

[Ross Krumbeck]

In the file:

ansible/roles/neutron/tasks/bootstrap.yml

name: Creating Neutron database is set to run_once. This is ok for the first deploy. But when trying to do a kolla-ansible deploy again there will be errors for the controller nodes:

fatal: [controller.example.com] => One or more undefined variables: 'dict object' has no attribute 'stdout'

This is because the task 'Reading json from variable' is relying on output from the 'Creating Neutron database' which does not exist after the first run due to the run_once in 'Creating Neutron database':

- name: Reading json from variable
  set_fact:
    database_created: "{{ (database.stdout.split('localhost | SUCCESS => ')[1]|from_json).changed }}"

Ross,

Is this still a problem in master? I can't replicate it.

[Ross Krumbeck (rkrum)]

This is a problem with Liberty release. It is actually caused by the ansible bug that doesn't use the correct servers when using run_once.
