Append to array

Hi guys,

This might be a duplicate topic but I wasn’t able to find the answer to my question.
if I define a variable array in a role like:

postgresql_pg_hba_default:

  • { type: local, database: all, user: all, address: ‘’, method: md5 }

  • { type: host, database: all, user: all, address: ‘127.0.0.1’, method: md5 }

I have a task in the role that will make sure that the items in the previous array are placed in pg_hba.conf

what I would like to achieve is appending to this array and having the same task in the role to add the extra item:

  • { type: host, database: all, user: test, address: ‘1.2.3.4’, method: md5 }

the end result that I would like to achieve is to have all 3 items in the file without having any extra tasks to add them, this means just updating the list/array at any level (in other roles or playbooks)

Thank you,

Elie.
