[Abdul Rahim]

Hello Experts,

As you can see struggling through basic tasks will appreciate any pointers , using ansible version 2.7

 cat inventory.yml

fabric01:

  hosts:

    build_node:

      build_host: 192.168.115.101

      build_username: root

      build_password: 123Abdul123

root@ansibile-launch:~/ansible/tasks/add-compute# cat add-compute.yml

---

# Demo Adding Compute Node

- name: Adding Compute Node

  hosts: build_node

  connection: local

  gather_facts: no

  tasks:

  - name: return motd to registered var

    ansible_user= "{{build_username}}"

    ansible_ssh_pass= "{{build_password}}"

    command: 'cp /root/setup_data.yaml /root/setup_data.yaml.bak'

Appreciate if you can please int me in the right direction here ..

Regards,

Without an error I can only guess, one thing i've noticed is that you
are incorrectly formatting the task

- name: return motd to registered var

command: 'cp /root/setup_data.yaml /root/setup_data.yaml.bak'
vars:
ansible_user= "{{build_username}}"
ansible_ssh_pass= "{{build_password}}"

Thans Brian , 

It fails with following 

root@ansibile-launch:~/ansible/tasks/add-compute# ansible-playbook -i inventory.yml add-compute.yml -vvvv

ansible-playbook 2.7.1

  config file = /etc/ansible/ansible.cfg

  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']

  ansible python module location = /usr/lib/python2.7/dist-packages/ansible

  executable location = /usr/bin/ansible-playbook

  python version = 2.7.12 (default, Dec  4 2017, 14:50:18) [GCC 5.4.0 20160609]

Using /etc/ansible/ansible.cfg as config file

setting up inventory plugins

/root/ansible/tasks/add-compute/inventory.yml did not meet host_list requirements, check plugin documentation if this is unexpected

/root/ansible/tasks/add-compute/inventory.yml did not meet script requirements, check plugin documentation if this is unexpected

Parsed /root/ansible/tasks/add-compute/inventory.yml inventory source with yaml plugin

ERROR! Syntax Error while loading YAML.

  mapping values are not allowed in this context

The error appears to have been in '/root/ansible/tasks/add-compute/add-compute.yml': line 11, column 23, but may

be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

  - name: Copy Test

          ansible_user: "{{build_username}}"

                      ^ here

We could be wrong, but this one looks like it might be an issue with

missing quotes.  Always quote template expression brackets when they

start a value. For instance:

    with_items:

      - {{ foo }}

Should be written as:

    with_items:

      - "{{ foo }}"

root@ansibile-launch:~/ansible/tasks/add-compute#

root@ansibile-launch:~/ansible/tasks/add-compute# cat add-compute.yml

It does work with below

root@ansibile-launch:~/ansible/tasks/add-compute# ansible-playbook -i new_inventory test.yml

[DEPRECATION WARNING]: Instead of sudo/sudo_user, use become/become_user and make sure become_method is 'sudo' (default). This feature will be removed in version 2.9. Deprecation warnings can be disabled by

setting deprecation_warnings=False in ansible.cfg.

Not sure what is wrong with the yml version of inventory and the variables called .. but I am able to now make progress , thanks for getting back to me on this

Hi Abdul,

You could remove the hosts from inventory.ym , else directly mention it in default hosts inventory file
