My playbook is as follows

- hosts: nodes  
become: yes  
tasks:
- name: Run Shell Script to get IPs with 4xx and 5xx errors

script: /home/ubuntu/ips.sh  
args:  
chdir: /home/ubuntu  
register: ips

- name:  
shell: echo “{{ hostvars[groups[‘nodes’][0]].ips.stdout}}” \> pip.txt  
delegate\_to: localhost

There are 10 ansible hosts. Is There a way I can access Ips.stdout from all 10 hosts from my local server. I’m able to get the first host by the above command. How can I access all 10 hosts stdout from a single variable?

Running shell like this will run the task as many times as it's hosts in nodes.  
Each one will overwrite the pip.txt file.

You can use a loop with with\_items like this

- debug: msg="{{ item.ips.stdout }}"  
&nbsp;&nbsp;with\_items: "{{ groups.nodes }}"  
&nbsp;&nbsp;delegate\_to: localhost

(just for the record, debug module always run on localhost, so with debug delegate\_to could be left out)

But still this task will still run as many times as there are hosts in nodes.  
To mitigate that you have "run\_once: true" that only run this task one time.

- debug: msg="{{ item.ips.stdout }}"  
&nbsp;&nbsp;with\_items: "{{ group.nodes }}"  
&nbsp;&nbsp;delegate\_to: localhost  
&nbsp;&nbsp;run\_once: true

But since you would like to have this in a file you would need to use Jinja template and the copy module.  
So instead of looping with with\_items you do the loop in Jinga template.

- copy:  
&nbsp;&nbsp;&nbsp;&nbsp;content: |  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{% for host in groups.nodes %}  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{{ hostvars[host].ips.stdout }}  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{% endfor %}}  
&nbsp;&nbsp;&nbsp;&nbsp;dest: /tmp/pip.txt  
&nbsp;&nbsp;delegate\_to: localhost  
&nbsp;&nbsp;run\_once: true
