Ansible filter using ad-hoc command

  • 772

How can I filter the nocache block or free block using ad-hoc command? I tried ansible centos1 -m setup -a 'filter=ansible_memory_mb.nocache' but doesn't filter it out.

ansible centos1 -m setup -a 'filter=ansible_memory_mb'
centos1 | SUCCESS => {
    "ansible_facts": {
        "ansible_memory_mb": {
            "nocache": {
                "free": 11808,
                "used": 926
            },
            "real": {
                "free": 10686,
                "total": 12734,
                "used": 2048
            },
            "swap": {
                "cached": 0,
                "free": 4096,
                "total": 4096,
                "used": 0
            }
        },
        "discovered_interpreter_python": "/usr/libexec/platform-python"
    },
    "changed": false
}

    You can't. As the documentation for setup says, "The filter option filters only the first level subkey below ansible_facts."

  2. this is a bit messy, but you can..

    I am running my ansible against my localhost, so you will have to modify the path a bit, and replace localhost

    ANSIBLE_LOAD_CALLBACK_PLUGINS=true ANSIBLE_STDOUT_CALLBACK=json ansible localhost -m setup | jq .plays[].tasks[].hosts.localhost.ansible_facts.ansible_memory_mb.nocache

    output:

    {
  "free": 11987,
  "used": 703
}
