sh Ansible Module

sh is a custom Ansible Module that lets you execute shell commands based on the output of another shell command or python code

Features

• Can make your Shell commands idempotent
• Execute commands with conditional shell commands or Python code
  • Condition can be:
    • stdout
    • rc (return code/exit_status)
    • stdout & rc

---

Usage

Full example is provided in sample_playbook.yml

- name: Name of the task
  sh:
    cmd: #command to run
    condition: # command to run as a condition (can be bash command or python code)
    lang: bash  # bash || Python
    if_stdout: # If condition-command-stdout

    if_stdout: 'ansible'
  register: test_bash

- debug:
    var: test_bash

• Execute shell command based on the stdout & rc of a Python code

- name: run command based on Python code
  sh:
    cmd: echo 'Execute some commands '
    condition: |
      import socket
      sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
      result = sock.connect_ex(('127.0.0.1',24))
      if result == 0:
         print "open"
         sock.close()
      else:
         print "not-open"
         sock.close()
         exit(1)
    lang: python
    if_rc: 1
    if_stdout: 'not-open'
  register: test_python

- debug:
    var: test_python
