Can we do the same with blockinfile?
For instance, if the variable is not found then omit only that item and
move on to the next item and update it.
Here is my play
- name: insert/update php configurations in App_config_file
blockinfile:
path: "/etc/php/7.4/fpm/php.ini_bak"
marker: ";# {mark} ANSIBLE MANAGED BLOCK ###"
block: |
{% for items in item %}
{{ items }}
{% endfor %}
when: item is not search(omit)
with_items:
- { "display_errors = {{service_configurations.display_errors | d(omit) }}"
}
- { "memory_limit = {{service_configurations.memory_limit | d(omit) }}M" }
Here is the output I'm getting:
root@aws-farrukhahmed-518:/etc/php/7.4/fpm# cat php.ini_bak
;# BEGIN ANSIBLE MANAGED BLOCK ###
memory_limit = {{service_configurations.memory_limit | d(omit) }}M
;# END ANSIBLE MANAGED BLOCK ###
root@aws-farrukhahmed-518:/etc/php/7.4/fpm#
Here is the command I'm using:
ansible-playbook -i hosts exec.yml -e
'{"service_configurations":{"display_errors":"On","memory_limit":"128"}}'
-vvv
The expected output should be:
;# BEGIN ANSIBLE MANAGED BLOCK ###
display_errors = On
memory_limit = 128M
;# END ANSIBLE MANAGED BLOCK ###
PS: It is mandatory for me to do this with the blockinfile module.
