how to read all lines from a file in ansible playbook

I have a file called packages.txt which contains a list of packages. I have to read each line of that package.txt through my ansible file rpm.yml. Here is my code

- hosts: myhost
  tasks:

     - name: RPM Filter
       theforeman.foreman.content_view_filter:
         username: "admin"
         password: "admin"
         server_url: "myhost"
         name: "rpm filter"
         organization: "myorg"
         content_view: "My content view"
         filter_type: "rpm"
         package_name: "{{ item }}"
         inclusion: True
       loop:
         - packages.txt

My packages.txt contains these

open-ssh
nginx
grafana
vim

Any help would be appreciated

You will need an additional task to read the file. The simplest way would be to cat the file and register into a variable. Then this variable can be used for the next task.

Something like:

    - name: get contents of package.txt
      command: "cat packages.txt"
      register: _packages

     - name: RPM Filter
       theforeman.foreman.content_view_filter:
         username: "admin"
         password: "admin"
         server_url: "myhost"
         name: "rpm filter"
         organization: "myorg"
         content_view: "My content view"
         filter_type: "rpm"
         package_name: "{{ item }}"
         inclusion: True
       loop: "{{ _packages.stdout_lines }}"
