Hi ,

While running the ansible task in azure pipeline we are getting the below warning message. Please let us know if we can ignore/suppress the warning.

[WARNING]: conditional statements should not include jinja2 templating

The logic behind your condition eludes me, but the expression for conditions are always subject to templating. This means you can't use {{, {% if, {% for etc.

You can start to convert your logic to

hostvar.values | dict2items | ... | count

Hi  Racke,

Can you please help me to form the logic as you suggested above for below condition

when: "{% for item in hostvars.values() %}{% if item.MyDoneVar|default(False) %}True{% endif %}{% endfor %}"

Instead of reverse engineering/guessing, why not tell us what you
actually had in mind when you added that condition?

Hi,

I have 3 host in my inventory group as below

Inventory:-

==========

---

all:

  children:

    dse_layer_7:

      hosts:

        XXXXX:

        XXXXX:

        XXXXX:

      vars:  

        ansible_user: XXXX

        ansible_connection: ssh

        ansible_password: "{{ lookup('file', 'XXXXXX) }}"

Scenario: - Want to run the below command on first host and if the command executed successfully skip the rest of the host. If it fails on first host ,command should run on second host and if the command executed successfully skip the rest of the host and so on.

command:-

=========

nodetool -u controlRole -pw '{{ controlRole_dse_layer7_pass }}' status | grep -A 10 {{ dse_layer_7_datacenter_name }}

so to achieve this  i wrote the playbook as below, which is working fine with warnings .In azure pipeline this warning is considered as failure.

Playbook:-

=============

---

- name: Check the status of DSE layer 7 cluster

  hosts: XXXX

  gather_facts: False

  serial: 1

  tasks:

    - meta: end_play

      when: "{% for item in hostvars.values() %}{% if item.MyDoneVar|default(False) %}True{% endif %}{% endfor %}"

    - name: nodetool status playbook execution

      import_role:

        name: ../roles/dse/nodetool_status_check

Role:-

=========

---

- name: Nodetool status for DSE layer 7 cluster

  block: 

    - name: Nodetool Status

      shell: nodetool -u controlRole -pw '{{ controlRole_dse_layer7_pass }}' status | grep -A 10 {{ dse_layer_7_datacenter_name }}

      register: result_nodetool

   - set_fact:

         MyDoneVar: True
