DESCRIPTION

is an extra-simple tool/framework/API for doing 'remote things'. this command allows you to define and run a single task 'playbook' against a set of hosts

COMMON OPTIONS

host pattern

--ask-vault-password, --ask-vault-pass

ask for vault password

--become-method 'BECOME_METHOD'

privilege escalation method to use (default=sudo), use ansible-doc -t become -l to list valid choices.

--become-password-file 'BECOME_PASSWORD_FILE', --become-pass-file 'BECOME_PASSWORD_FILE'

Become password file

--become-user 'BECOME_USER'

run operations as this user (default=root)

--connection-password-file 'CONNECTION_PASSWORD_FILE', --conn-pass-file 'CONNECTION_PASSWORD_FILE'

Connection password file

--list-hosts

outputs a list of matching hosts; does not execute anything else

--playbook-dir 'BASEDIR'

Since this tool does not use playbooks, use this as a substitute playbook directory.This sets the relative path for many features including roles/ group_vars/ etc.

--private-key 'PRIVATE_KEY_FILE', --key-file 'PRIVATE_KEY_FILE'

use this file to authenticate the connection

--scp-extra-args 'SCP_EXTRA_ARGS'

specify extra arguments to pass to scp only (e.g. -l)

--sftp-extra-args 'SFTP_EXTRA_ARGS'

specify extra arguments to pass to sftp only (e.g. -f, -l)

--ssh-common-args 'SSH_COMMON_ARGS'

specify common arguments to pass to sftp/scp/ssh (e.g. ProxyCommand)

--ssh-extra-args 'SSH_EXTRA_ARGS'

specify extra arguments to pass to ssh only (e.g. -R)

--syntax-check

perform a syntax check on the playbook, but do not execute it

--task-timeout 'TASK_TIMEOUT'

set task timeout limit in seconds, must be positive integer.

--vault-id

the vault identity to use

--vault-password-file, --vault-pass-file

vault password file

--version

show program's version number, config file location, configured module search path, module location, executable location and exit

-B 'SECONDS', --background 'SECONDS'

run asynchronously, failing after X seconds (default=N/A)

-C, --check

don't make any changes; instead, try to predict some of the changes that may occur

-D, --diff

when changing (small) files and templates, show the differences in those files; works great with --check

-K, --ask-become-pass

ask for privilege escalation password

-M, --module-path

prepend colon-separated path(s) to module library (default=~/.ansible/plugins/modules:/usr/share/ansible/plugins/modules)

-P 'POLL_INTERVAL', --poll 'POLL_INTERVAL'

set the poll interval if using -B (default=15)

-T 'TIMEOUT', --timeout 'TIMEOUT'

override the connection timeout in seconds (default=10)

-a 'MODULE_ARGS', --args 'MODULE_ARGS'

The action's options in space separated k=v format: -a 'opt1=val1 opt2=val2'

-b, --become

run operations with become (does not imply password prompting)

-c 'CONNECTION', --connection 'CONNECTION'

connection type to use (default=smart)

-e, --extra-vars

set additional variables as key=value or YAML/JSON, if filename prepend with @

-f 'FORKS', --forks 'FORKS'

specify number of parallel processes to use (default=5)

-h, --help

show this help message and exit

-i, --inventory, --inventory-file

specify inventory host path or comma separated host list. --inventory-file is deprecated

-k, --ask-pass

ask for connection password

-l 'SUBSET', --limit 'SUBSET'

further limit selected hosts to an additional pattern

-m 'MODULE_NAME', --module-name 'MODULE_NAME'

Name of the action to execute (default=command)

-o, --one-line

condense output

-t 'TREE', --tree 'TREE'

log output to this directory

-u 'REMOTE_USER', --user 'REMOTE_USER'

connect as this user (default=None)

-v, --verbose

verbose mode (-vvv for more, -vvvv to enable connection debugging)

ENVIRONMENT

The following environment variables may be specified.

ANSIBLE_CONFIG -- Specify override location for the ansible config file

Many more are available for most options in ansible.cfg

For a full list check https://docs.ansible.com/. or use the ansible-config command.

FILES

/etc/ansible/ansible.cfg -- Config file, used if present

~/.ansible.cfg -- User config file, overrides the default config if present
