问题
If I try to use expect module in YAML file like this:
name: some tests
hosts: sw-test
gather_facts: False
tasks:
- name: do reload in case of "catting off"
expect:
command: reload in 30
responses:
'Reload scheduled in 30 minutes by admin on vty0 (192.168.253.20)\nProceed with reload? \[confirm\]' : y
echo: yes
But there is a problem with connection:
root@Kali:/etc/ansible# ansible-playbook test3 -u admin -k -vvvv

Is it possible to use expect module with cisco ios switch? I have no such problem when I use for instance "ios_command" module.
回答1:
I guess, you are out of luck here, because for expect module you need:
Requirements (on host that executes module)
python >= 2.6
pexpect >= 3.3
And there are hardly any python and pexpect present on your IOS switch.
