All what I need is in title, for example I want to know how I can do somethings like that : 

---
- hosts: ansible-clients

  tasks:
    - name: Fetch source list from clients
      fetch: src=/etc/apt/sources.list
             dest=/tmp/allnodes.sourcelist

OR in simply way

echo remote@/etc/apt/sources.list >> local@/tmp/allnodes.sourcelist

I can create and run script in local but the only condition I have is to do all actions in one playbook.

You can use this play:

---
- hosts: ansible-clients
  tasks:
    - name: Fetch source list from clients
      fetch:
        src: /etc/apt/sources.list
        flat: yes
        dest: "/tmp/{{ inventory_hostname }}.sourcelist"
    - name: Merge files
      run_once: yes
      delegate_to: localhost
      shell: "cat /tmp/{{ item }}.sourcelist >> /tmp/allnodes.sourcelist"
      with_items: "{{ groups['ansible-clients'] }}"

  • First task is used to fetch all files from remotes and store them in /tmp. inventory_hostname is used in filename to be sure it is unique.

  • Second task is run once on any host, and append all files (get list of hosts linked to group ansible-clients) in final file

    `run_once` limits the job count to 1, but that will still run on a remote host. You have to add `delegate_to: localhost` to concat the files locally. – dgw Dec 12 '16 at 14:18
