Access register array defined in one host group from another host group

[Imran Khan]

Hello, is it possible to do the following

    - hosts: localhost

      gather_facts: False

      

      tasks:

          #

          #

        - name: create new IP Addresses

          #debug: msg={{resultip.stdout.split('.')[3]}}

          shell: echo "{{ ServerIP.split('.')[0] }}.{{ ServerIP.split('.')[1] }}.{{ ServerIP.split('.')[2] }}.{{ item }}"

          with_items: result.stdout_lines

          register: new_ips

          #

          #

    

    - hosts: myhosts

      gather_facts: False

          #

          #

        - name: Replace ServerIP in config_file on myhosts

          shell: cd /home/imran/Desktop/tobefetched; sed -i '/{{String1}}/ c "ServerIP" ':' "{{hostvars.localhost.new_ips.{{item}}}}" ' config_file

          with_items: hostvars.localhost.new_ips.stdout_lines

          #

          #

Summary: I just want to access the individual entries of new_ips (defined in localhost) in hosts: myhosts in a loop. How can I do that?

Sample Output of what is saved in new_ips, when array size is 2:

    TASK: [Checking to see if new IPs were stored] ******************************** 

    ok: [localhost] => {

        "new_ips": {

            "changed": true, 

            "msg": "All items completed", 

            "results": [

                {

                    "changed": true, 

                    "cmd": "echo \"11.11.4.74\"", 

                    "delta": "0:00:00.001776", 

                    "end": "2014-08-25 22:28:46.163851", 

                    "invocation": {

                        "module_args": "echo \"11.11.4.74\"", 

                        "module_name": "shell"

                    }, 

                    "item": "74", 

                    "rc": 0, 

                    "start": "2014-08-25 22:28:46.162075", 

                    "stderr": "", 

                    "stdout": "11.11.4.74"      # I need this entry in myhosts

                }, 

                {

                    "changed": true, 

                    "cmd": "echo \"11.11.4.138\"", 

                    "delta": "0:00:00.001896", 

                    "end": "2014-08-25 22:28:46.227298", 

                    "invocation": {

                        "module_args": "echo \"11.11.4.138\"", 

                        "module_name": "shell"

                    }, 

                    "item": "138", 

                    "rc": 0, 

                    "start": "2014-08-25 22:28:46.225402", 

                    "stderr": "", 

                    "stdout": "11.11.4.138"     # I need this entry in myhosts

                }

            ]

        }

    }

Note: Array size can change, this is just a sample output

Probably something like

hostvars[groups['webservers']|first].new_ips

You mean hostvars[groups['localhost']|first.new_ips

Doesn't work!

[Imran Khan]

{{hostvars[groups['localhost'].new_ips.results.stdout}} 

Gives the following error: One or more undefined variables: 'dict object' has no attribute 'localhost'

You know what- I answered your title, not your question. If you don't
want to have to try and persist things between plays, you might have
more luck with something like this:

- hosts: myhosts
tasks:
- shell: echo things
local_action: true
register: new_ips
- shell: echo other things {{new_ips}}

but there's nothing in your example that seems to necessitate anything
that you're doing.

haha.....okay! I did not want to post my whole playbook as it might get confusing. I really do appreciate your help though. Here is a sizeable chunk of the playbook which might make things easy  (or difficult) to understand :)
