I'm trying to use Ansible to hit a bunch (100+) Cisco Catalyst switches and check if they have a certain line card installed. Via SSH, this can be done with the "sh mod" command. I want to parse the output of that command in a playbook and then show the output of the command if a certain string matches. Right now with the playbook below I get the following error:
fatal: [redacted-hostname]: FAILED! => {"failed": true, "msg": "The conditional check 'showmod | search(\"4548\")' failed. The error was: Unexpected templating type error occurred on ({% if showmod | search(\"4548\") %} True {% else %} False {% endif %}): expected string or buffer\n\nThe error appears to have been in '/etc/ansible/playbooks/linecard-4548.yaml': line 22, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n - debug: \"msg='4548 Card Found'\"\n ^ here\n"}
Current playbook code:
---
- hosts: redacted-hostname
gather_facts: yes
connection: local
tasks:
- name: SYS | Define provider
set_fact:
provider:
host: "{{ inventory_hostname }}"
username: redacted-user
password: redacted-password
- name: IOS | Get Module List
ios_command:
provider: "{{ provider }}"
commands:
- sh mod | inc 4548
register: showmod
- debug: "msg='4548 Card Found'"
when: showmod.stdout | search("/4548/")
I've tried the when in the debug with and without the .stdout to no avail. I've done some research and the error I'm getting usually occurs when, in my case, showmod is undefined but it definitely is. If I replace the debug with the following snippet, the playbook runs fine but of course it'll print the output for every switch which isn't what I want.
- name: IOS | Show Output
debug:
var: showmod
Any suggestions?
