Ansible stdout Formatting

问题

Assuming the below tasks:

shell: "some_script.sh" register: "some_script_result"

debug: msg: "Output: {{ some_script_result.stdout_lines }}

I receive the below output:

"msg": "Output: [u'some_value',u'some_value2,u'some_value3]"

How do I get the output to print as?

"msg":

Output:

some_value

some_value2

some_value3

Ansible version is 2.4.2.

Thank you!

Try this option. You’ll love it.

There's a new YAML callback plugin introduced with Ansible 2.5 — meaning any machine running Ansible 2.5.0 or later can automatically start using this format without installing custom plugins.

To use it, edit your ansible.cfg file (either global, in /etc/ansible/ansible.cfg, or a local one in your playbook/project), and add the following lines under the [defaults] section:

# Use the YAML callback plugin.
stdout_callback = yaml
# Use the stdout_callback when running ad-hoc commands.
bin_ansible_callbacks = True

Now I can easily read through your output message

Another option:

https://blog.alexgittings.com/improving-the-ansible-output-with-anstomlog/

just store it inside ansible/ansible.cfg

➜ tree ansible     
ansible
├── ansible.cfg
├── callbacks
│   ├── anstomlog.py
└── playbooks
    └── nginx.yaml

ANSIBLE_CONFIG=ansible/ansible.cfg ansible-playbook -u centos --private-key .ssh/key -i `terraform output bastion_ip`, ansible/playbooks/nginx.yaml
