Blockinfile looping overwrites even though the marker is differnent

[rcst.e...@gmail.com]

Hi all,

I am trying to insert a block of lines via Blockinfile module and it is overwriting the previous change even though I am using different marker.

I have configured the code like below:

----------

- name: update zones on master nodes

  blockinfile:

    dest: /etc/icinga2/zones.conf

    backup: yes

    marker: "// {mark} inserted {{ item[0] }}"

    block: |

      {% for host in groups[groupname] %}

      object Endpoint "{{ hostvars[host].ansible_fqdn }}" {

        host = "{{ hostvars[host].ansible_eth0.ipv4.address }}"

      }

      {% endfor %}

      object Zone "{{ groupname }}" {

        endpoints = [ {% for host in groups[groupname] -%} "{{ hostvars[host].ansible_fqdn }}" {%- if not loop.last %}, {% endif -%} {%- endfor %} ]

        parent = "master"

      }

    insertafter: 'satellite configuration'

  delegate_to: "{{ item[1] }}"

  vars:

    ansible_become_pass: "{{ hostvars[item[1]].ansible_become_pass }}"

  with_nested:

    - "{{ groupname }}"

    - "{{ groups['icinga2-master'] }}"

  when: inventory_hostname == groups[groupname][0]

----------

And my inventory files is like below:

----------

[icinga2-master]

rcstmon01

rcstmon02

[icinga2-satellite-rcst]

bnemon01

bnemon02

[icinga2-satellite-test]

bnetest01

[icinga2-satellite-rcst:vars]

groupname=icinga2-satellite-rcst

[icinga2-satellite-test:vars]

groupname=icinga2-satellite-test

[icinga2-satellite:children]

icinga2-satellite-rcst

icinga2-satellite-test

[icinga2-cluster:children]

icinga2-master

icinga2-satellite

----------

When I run the playbook with -vvv option, I can see the correct contents are show as stdout but when I check the resulting file, only the last change is shown. Is there any way I can add blocks without overwriting? Shouldn't it stop overwriting when different marker is set? Thank you.
