'rc' check failure - 'dict object' has no attribute 'rc'

[Imam Toufique]

Hi,

I am new in ansible world, trying to figure out playbook where I use 'grep' to check for netmask address from a text file and capture the exit code with 'register' ( see below).  

My vars/main.yml looks like this:

ipmitool_lan:

  root:

    netmask: 255.0.0.0

    defgw: 10.1.1.1

My tasks/main.yml looks like this:

---

####

- name: HP server netmask setup check

  command: grep -q {{ item.value.netmask }} /tmp/hponcfg.out

  register: ipmask

  with_dict: "{{ ipmitool_lan }}"

  ignore_errors: yes

#- debug: msg= "{{ ipmask.rc }}"

- block:

    - name: HP server setup netmask

      replace:

        path: "/tmp/hponcfg.out"

        regexp: >-

          (<SUBNET_MASK.VALUE.)(=)(.*\b)("\/>)

        replace: >-

          \1 \2 "{{ item.value.netmask }}\4

      with_dict: "{{ ipmitool_lan }}"

  when:

    - ansible_system_vendor == 'HP'

    - ipmask.rc != 0

My /tmp/hponcfg.out file looks like this: 

--------snip-------

<SPEED_AUTOSELECT VALUE = "Y"/>

    <NIC_SPEED VALUE = "10"/>

    <FULL_DUPLEX VALUE = "N"/>

    <IP_ADDRESS VALUE  = "10.3.254.221"/>

    <SUBNET_MASK VALUE = "255.255.0.0"/>

    <GATEWAY_IP_ADDRESS VALUE = "10.1.1.1"/>

-------snip-----------

when the above playbook is run, I get the following error:

TASK [ipmi : HP server setup netmask] ****************************************************************************

task path: /data/ansible-hpc/production/global/pkgs/20180703_2227/roles/ipmi/tasks/main.yml:14

fatal: [compute-13-11]: FAILED! => {

    "msg": "The conditional check 'ipmask.rc != 0' failed. The error was: error while evaluating conditional (ipmask.rc != 0): 'dict object' has no attribute 'rc'\n\nThe error appears to have been in '/data/ansible-hpc/production/global/pkgs/20180703_2227/roles/ipmi/tasks/main.yml': line 14, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n- block:\n    - name: HP server setup netmask\n      ^ here\n"

data structure of this run looks like this, where is clear that 'ipmask.rc != 0' 

 "item": {

        "key": "root", 

        "value": {

            "defgw": "10.1.1.1", 

            "netmask": "255.0.0.0"

        }

    }, 

    "msg": "non-zero return code", 

    "rc": 1, 

    "start": "2018-07-06 23:44:31.061066", 

    "stderr": "", 

    "stderr_lines": [], 

    "stdout": "", 

    "stdout_lines": []

It looks like "rc": value is '1' , doesn't it?  Well, I am no expert at this but at least that's what I can see.  

Not sure what I am doing wrong, I am out of ideas.  I need to get this resolved to move forward, so, any help will be greatly appreciated!

Hi Imam Toufique

ipmask variable contains complex data structure, just try 

- debug: var="{{ ipmask }}"
to see it

so you need to use

when: ipmask.results[0].rc != 0
in your condition.

HIWH,

Hi Daria, 

that worked!  thanks.  But, I am not sure how it did though :-)  '-debug' output for ipmask produces the following:

TASK [ipmi : debug] **********************************************************************************************

task path: /data/ansible-hpc/production/global/pkgs/20180703_2227/roles/ipmi/tasks/main.yml:15

ok: [compute-13-11] => {

    "<type 'dict'>": "VARIABLE IS NOT DEFINED!: "

}

Would you mind explaining your solution a bit?

thanks again!  Very much appreciated!

When outputting a variable with debug, you do NOT use the curly braces.

If you use the curly braces, you are asking debug to output a variable with the name contained in ipmask, rather than the value of ipmask itself. Because the value contained in ipmask is not the name of a variable, debug complains that it is not defined.

Run this to see what I am talking about:

---
- hosts: localhost
  gather_facts: false
  become: false

  # fred contains a value, mary contains fred's NAME
  vars:
     fred: "123"
     mary: "fred"

  tasks:
     - debug:
         var: fred

     - debug:
         var: "{{ mary }}"

​S​

o

​ to output the value of ipmask, you need this​

:

- debug:

   var: ipmask
