Hi,  
I try to connect to a list of Sentinel host to get the master redis host and port.

- name: “CONNECT SENTINEL” command: “redis-cli -h {{ item.allowed\_host }} -p {{ item.port }} SENTINEL get-master-addr-by-name redis-pex-01” with\_items: “{{ production.redis\_params.sentinels }}” register: status\_sentinel ignore\_errors: yes

I try to display result f register value:

}

But when it tries to parse to have detail it doesn’t work:

- name: “DISPLAY SENTINEL VAR 1 1”  
debug: msg={{ status\_sentinel.results.cmd }}  
ignore\_errors: yes

```auto
- name: "DISPLAY SENTINEL VAR 1 2"
  debug: msg={{ item.cmd }}
  with_items: ${status_sentinel.results}
  ignore_errors: yes

```

TASK [DISPLAY SENTINEL VAR 1 1] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*  
fatal: [pyxrrsap02.pyx.erp]: FAILED! =\> {“failed”: true, “msg”: “ERROR! ‘list object’ has no attribute ‘cmd’”}  
…ignoring

TASK [DISPLAY SENTINEL VAR 1 2] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*  
fatal: [pyxrrsap02.pyx.erp]: FAILED! =\> {“failed”: true, “msg”: “ERROR! ‘unicode object’ has no attribute ‘cmd’”}  
…ignoring

or like this :

- name: “DISPLAY SENTINEL VAR 2 1”  
debug: var={{ item }}  
with\_items: ${status\_sentinel.results}  
ignore\_errors: yes

doesn’t work:  
TASK [DISPLAY SENTINEL VAR 2 1] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*  
ok: [pyxrrsap02.pyx.erp] =\> (item=${status\_sentinel.results}) =\> {  
“${status\_sentinel.results}”: “VARIABLE IS NOT DEFINED!”,  
“item”: “${status\_sentinel.results}”

Any idea ?

SOLVED:

Simple by using : [0][0] and [0][1] to get the correct value/parameters.
