지정된 모듈을 실행한다.(default=command)

-m MODULE_NAME, --module-name=MODULE_NAME

-u, --user

지정된 사용자로 접속한다. (default=None)

-u REMOTE_USER, --user=REMOTE_USER

Modules

get_url

Downloads files from HTTP, HTTPS or FTP to the remote server. The remote server must have direct access to the remote resource.

By default, if an environment variable <protocol>_proxy is set on the target host, requests will be sent through that proxy. This behaviour can be overridden by setting a variable for this task (see setting the environment), or by using the use_proxy option. HTTP redirects can redirect from HTTP to HTTPS so you should be sure that your proxy environment for both protocols is correct.

From Ansible 2.4 when run with --check, it will do a HEAD request to validate the URL but will not download the entire file or verify it against hashes. For Windows targets, use the win_get_url module instead.

Example

- name: Download the Asterisk archive
  get_url: url={{ asterisk_url }} dest={{ asterisk_source_file }}
  register: asterisk_archive

ping

A trivial test module, this module always returns pong on successful contact. It does not make sense in playbooks, but it is useful from /usr/bin/ansible to verify the ability to login and that a usable Python is configured.

This is NOT ICMP ping, this is just a trivial test module that requires Python on the remote-node.

For Windows targets, use the win_ping module instead. For Network target, use the net_ping module instead.

Example

ansible asterisk -i inventory/test-virtualbox -u pchero -m ping
192.168.100.10 | SUCCESS => {
    "changed": false,
    "ping": "pong"
}
