This is my playbook (dbmaster.yml)
- hosts: dbmasters
remote_user: root
roles:
- common
- dbmaster
if I run this. it will work fine
sudo -u test ansible-playbook dbmasters.yml
however if I run it on one specific host (host1)
sudo -u test ansible-playbook dbmasters.yml -l host2
I got error in one task
fatal: [host2] => {'msg': "One or more undefined variables: 'dict' object
has no attribute 'ansible_eth0'", 'failed': True}
this is because it needs this variable from host1
I tried gather_facts=yes and it does not work
I tried serial=1. This will work one host at a time but there is no option
to stop on the first host.
any idea who to run on one host and get facts from both hosts or will
serial=1 stop at the first host.
I read ansible doc http://docs.ansible.com/guide_rolling_upgrade.html and
also tried this option
- hosts: dbmasters
tasks: []
- hosts: dbmasters
remote_user: root
roles:
- common
- dbmaster
with a blank task but it does not work either.
