Error Recognition in Ansible Ad-hoc Commands

Is there a way to capture the stdout and stderr separately in bash, maybe as a tuple, for ansible ad-hoc commands? Something like: stdout, stderr= ansible -i hosts -m shell -a "command"

Solution

  • You could use option -t to log output in JSON format. For example if I execute

    ansible -m shell -a "echo test" -t tmp localhost

    then in the file ./tmp/localhost I'll get this output:

    {
  "changed": true,
  "cmd": "echo test",
  "delta": "0:00:00.006099",
  "end": "2020-04-14 11:43:01.878959",
  "rc": 0,
  "start": "2020-04-14 11:43:01.872860",
  "stderr": "",
  "stderr_lines": [],
  "stdout": "test",
  "stdout_lines": [
    "test"
  ]
}

    You can then parse stdout and stderr.
