ansible include_vars订购问题

Question

#file: cmservers.yml

 - hosts: cmservers
   tasks:
     - include_vars: /var/cm/local/ansible/vars/cmusers.yml
     - debug: var=users
   roles:
     - ansible-users-master

I am finding that the roles tasks are being executed first, however the users list needs to be defined first, which is not happening. Any help appreciated.

Answer 1

Alternatively you can use vars_files directive in the playbook. This comes handy when you store your variables in a role vars/main.yml , but there are some additional variables, or some private data (you might use Ansible Vault for that) to include while executing playbook.

#file: cmservers.yml

 - hosts: cmservers
   vars_files:
     - /var/cm/local/ansible/vars/cmusers.yml
   roles:
     - ansible-users-master

Since include_vars is a task it's better to use it in roles/hanlders and use vars_files in playbooks instead. It is also easier to pass Ansible command line variables with vars_files . For further info see: http://docs.ansible.com/ansible/playbooks_variables.html

Answer 2

You can use pre_tasks to make sure that some tasks are executed before role and post_tasks to make sure that some tasks are executed after the role is applied. So changing your tasks to pre_tasks will fix the problem.

- hosts: cmservers

  pre_tasks:
    - include_vars: /var/cm/local/ansible/vars/cmusers.yml
    - debug: var=users

  roles:
    - ansible-users-master

You can check the role documentation for further details.
