Hi, I have playbook to retrieve the Instance id of Openstack nodes.Now everything works fine but the resgitered value for instid.stdout\_lines gets an undefined error. **The error was: ‘dict object’ has no attribute ‘stdout\_lines’** … but when i debug the complete registered variable instid i see stdout\_lines. but why its failing when i debug it using instid.stdout\_lines “item”: “TOMCS2”, “rc”: 0, “start”: “2019-09-24 09:15:45.801051”, “stderr”: “”, “stderr\_lines”: , “stdout”: “e8ebc5a4-17f3-4b80-a935-03164211a804 TOMICS2”, **“stdout\_lines”: [** **“e8ebc5a4-17f3-4b80-a935-03164211a804 TOMCS2”** - hosts: nodes[0] gather\_facts: false tasks: - name: Collect Hostnames set\_fact: host\_lists: “{{ hostvars[inventory\_hostname][‘groups’][‘nodes’] }}” - name: Create Hostname as per the Name in openstack names set\_fact: fact: ‘{{ ([“TOM”] \* host\_lists|length)|zip(host\_lists)|map(“join”)|list}}’ - name: Debug the required list debug: msg: “{{ fact }}” - hosts: 127.0.0.1 gather\_facts: false tasks: - name: Retrieve tenantID shell: openstack project list | awk ‘/ TOM / { print $2 }’ register: tenantid - name: Retrieve instance id from tenant shell: openstack server list --all-projects --project “{{ tenantid.stdout }}” | awk ‘NR \> 3 { print $2, $4 }’ | grep -i “{{ item }}” with\_items: “{{ hostvars[groups[‘nodes’][0]][‘fact’] }}” register: instid - name: Debug Instance id and Tennat id delegate\_to: localhost debug: msg: - “Tenant ID:” - “{{ tenantid.stdout }}” - “===============================” - "Instance ID of the VMs in TOM - “{{ instid.stdout\_lines}}” ---

What is the _complete_ output from a debug of instid? Regards, K. ---

When using register with with\_items/loop you'll have instid.results which is a list where each item contain the output for each command. When you get errors like this always run a   - debug: var=instid ---

There are 11 items , i will paste the out put of one item, all others are similar, or this mail will be lengthy.

Hi Kai, I had already tried it it gives me o/p as same as : debug: msg: {{ instid }} Both the o/ps are similar. Now i want the stdout\_lines for each item as my desired o/p something like: e8ebc5a4-17f3-4b80-a935-03164211a804 TOMICS2 7865dvgsf-17f3-4b80-a935-03164211a804 TOMICS1 abc12345g-17f3-4b80-a935-03164211a804 TOMIAS2 ---

As I wrote instid contains a results which is a list so you need to loop over it to get the individual results. - debug: msg="{{ item.stdout }}"   with\_items: "{{ instid.results }}" ---

Post the _complete_ output of - debug: var: instid Posting snippets is useless. ---

Hi Kai, I could do achieve what i intended. I made the following changes using Jinja format and my issue solved. Thanks for the help. Th echanges i made was: In the Instance id section i used the foloing formula and it worked like a charm. - name: Set fact for Instance id from Tenant ID delegate\_to: localhost set\_fact: id\_list: “{% for item in instid.results %} {{ item.stdout\_lines[0].split()[0] }} {% endfor %}” - name: Set fact for Desired Instance ids set\_fact: desired\_instid: “{{ id\_list.split() }}”
