Hi,
I guess this is fairly simple question, but I’m stuck with it…
I have a playbook that checks whether services are up on hosts and starts them if they are not in started state, for example:
- hosts: mailservers
tasks:
- name: Check amavis service, and start if needed.
service: name=amavis state=started
What if i wanted to leave service in stopped state only on one of the hosts in “mailservers” group while performing this playbook? How can I achieve that?
I forgot to mention that idea is to do this through host variable file, and not through playbook itself.
Set a variable called bar for this host foo in the host_vars/foo file
and only execute the task, when this variable is not set:
- hosts: mailservers
tasks:
- name: Check amavis service, and start if needed.
service: name=amavis state=started
when: hostvars[foo]['bar']|default('') is undefined
I'm not sure what exactly has to be inside the default, but using
default avoids errors when the variable bar is undefined...
