Question:
Using Ansible I’m having a problem registering a variable the way I want. Using the implementation below I will always have to call .stdout on the variable – is there a way I can do better?
My playbook:
Note the unwanted use of .stdout – I just want to be able to use the variable directly without calling a propery…?

The output when I execute the playbook:

Any help or insights appreciated – thank you 🙂
Answer:
If I understood it right you want to assign deploy_dir.stdout to a variable that you can use without stdout key. It can be done with set_fact module:

tasks: - name: init deploy dir shell: echo ansible-deploy-$(date +%Y%m%d-%H%M%S-%N) # http://docs.ansible.com/ansible/playbooks_variables.html register: deploy_dir - set_fact: my_deploy_dir="{{ deploy_dir.stdout }}" - debug: var=my_deploy_dir |
