Accessing file content via ansible

[Kunalsing Thakur]

file.txt

rpmname: version

rpmname: version

Playbook:-

- hosts: all
  gather_facts: false

  tasks:
  - name: store the value
    shell: cat /etc/ansible/playbooks/file.txt
    register: versions
  - name: Ansible Dictionary variable Example
    debug:
      msg: "rpmname is {{ item.key}} and value is {{item.value}}"

i want to access multiple key values in ansible -playbook to perform operation. looks like something is missing to access that values.

Where did 'item' come from? Usually, when you use a task in a loop, you
can access the loop item via the variable 'item'. I don't see a loop in
your playbook.

In your example, look at versions.stdout for file contents. Or use the
Slurp module to read file contents.

Hi Sudheer,

Thats the problem now how should we iterate items.

[test@4c594b5b8054 playbooks]$ ansible-playbook -vv test3.yaml
ansible-playbook 2.8.1
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/home/test/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible-playbook
  python version = 2.7.5 (default, Jun 20 2019, 20:27:34) [GCC 4.8.5 20150623 (Red Hat 4.8.5-36)]
Using /etc/ansible/ansible.cfg as config file

PLAYBOOK: test3.yaml ********************************************************************************************
1 plays in test3.yaml

PLAY [all] ******************************************************************************************************
META: ran handlers

TASK [store the value] ******************************************************************************************
task path: /etc/ansible/playbooks/test3.yaml:5
changed: [127.0.0.1] => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"}, "changed": true, "cmd": "cat /etc/ansible/playbooks/file.txt", "delta": "0:00:01.326287", "end": "2019-07-11 12:33:51.894849", "rc": 0, "start": "2019-07-11 12:33:50.568562", "stderr": "", "stderr_lines": [], "stdout": "httpd: 2.4\napache: 2.8", "stdout_lines": ["httpd: 2.4", "apache: 2.8"]}

TASK [Ansible Dictionary variable Example] **********************************************************************
task path: /etc/ansible/playbooks/test3.yaml:8
fatal: [127.0.0.1]: FAILED! => {"msg": "with_dict expects a dict"}

PLAY RECAP ******************************************************************************************************
127.0.0.1                  : ok=1    changed=1    unreachable=0    failed=1    skipped=0    rescued=0    ignored=0

in this example its required the content should be dictionary format.

But if you take vars in anisbleplaybook itself it will work because vars is in dict format.
