Ansible postgresql_db task fails after a very long pause - postgresql

Question

The following ansible task (in a vagrant VM) fails :
- name: ensure database is created
postgresql_db: name={{dbname}}
sudo_user: postgres
the task pauses for a few minutes before failing
the vagrant VM is a centos6.5.1,
the tasks output is :
TASK: [postgresql | ensure database is created] *******************************
fatal: [192.168.78.6] => failed to parse:
We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:
#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.
[sudo via ansible, key=glxzviadepqkwddapvjheeuillbdakly] password:
FATAL: all hosts have already failed -- aborting
I have verified that postgres is prooperly installed
by doing vagrant ssh and connecting vial psql.
I also validated that I can do a "sudo su postgres" within the VM ...
======== update
It looks like the problem is the sudo_user: postgres, because removing the
above postgres tasks and replacing with this one causes the same problem :
- name: say hello from postgress
command: echo "hello"
sudo_user: postgres
the output is exactly the same as above, so it's really a problem of
ansible doing a sudo_user on centos6.5
one interesting observation, although I can do "sudo su postgres" from
inside the vm
when I call "psql" (as the postgres user) I get the message :
could not change directory to "/home/vagrant": Permission denied
but the psql shell still starts successfully
======== conclusion
Problem was fixed by changing to a stock centos box,
lesson learned : when using ansible/vagrant, only use stock OS images...

Answer 1

I am using the wait for host:
- local_action: wait_for port=22 host="{{PosgresHost}}" search_regex=OpenSSH delay=1 timeout=60
ignore_errors: yes
PS:
I think you should use gather_facts: False and do setup after ssh is up.
Example main.yml:
---
- name: Setup
hosts: all
#connection: local
user: root
gather_facts: False
roles:
- main
Example roles/main/tasks/main.yml
- debug: msg="System {{ inventory_hostname }} "
- local_action: wait_for port=22 host="{{ inventory_hostname}}" search_regex=OpenSSH delay=1 timeout=60
ignore_errors: yes
- action: setup
ansible-playbook -i 127.0.0.1, main.yml
