Invoke another 'play' based on output of another play - Ansible -

i trying use ansible check if selinux enabled (set enforcing), , if not, enable it. play enable selinux must invoked if selinux disabled.

the playbook looks so:

- hosts:    # root should execute this.   remote_user: root   become: yes    tasks:      # check if selinux enabled.     - name: check if selinux enabled       tags: selinuxcheck       register: selinuxcheckout       command: getenforce     - debug: var=selinuxcheckout.stdout_lines      - name: enable selinux if not enabled       tags: enableselinux       selinux: policy=targeted state=enforcing       when: selinuxcheckout.stdout_lines == "enforcing"     - debug: var=enableselinuxout.stdout_lines 

when run this, task enableselinux fails reason, "conditional check failed". output is:

task [debug] ******************************************************************* task path: /root/ansible/playbooks/selinuxconfig.yml:24 ok: [localhost] => {     "selinuxcheckout.stdout_lines": [         "enforcing"     ] }  task [enable selinux if not enabled already] *********************************** task path: /root/ansible/playbooks/selinuxconfig.yml:26 skipping: [localhost] => {"changed": false, "skip_reason": "conditional check failed", "skipped": true} 

my questions:
1. correct way play execute depending on output play?
2. how work?

your playbook correct. stdout_lines list. have compare first element in list. try this:

when: selinuxcheckout.stdout_lines[0] == "enforcing"
