ansible-pull

pulls playbooks from a VCS repo and executes them for the local host

Synopsis

ansible-pull -U <repository> [options] [<playbook.yml>]

Description

is used to up a remote copy of ansible on each managed node, each set to run via cron and update playbook source via a source repository. This inverts the default push architecture of ansible into a pull architecture, which has near-limitless scaling potential.

The setup playbook can be tuned to change the cron frequency, logging locations, and parameters to ansible-pull. This is useful both for extreme scale-out as well as periodic remediation. Usage of the ‘fetch’ module to retrieve logs from ansible-pull runs would be an excellent way to gather and analyze remote logs from ansible-pull.

Common Options

--accept-host-key
adds the hostkey for the repo url if not already added
--ask-su-pass
ask for su password (deprecated, use become)
--ask-sudo-pass
ask for sudo password (deprecated, use become)
--ask-vault-pass
ask for vault password
--check
don’t make any changes; instead, try to predict some of the changes that may occur
--clean
modified files in the working repository will be discarded
--diff
when changing (small) files and templates, show the differences in those files; works great with –check
--full
Do a full clone, instead of a shallow one.
--list-hosts
outputs a list of matching hosts; does not execute anything else
--private-key, --key-file
use this file to authenticate the connection
--purge
purge checkout after playbook run
--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)
--skip-tags
only run plays and tasks whose tags do not match these values
--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)
--track-subs
submodules will track the latest changes. This is equivalent to specifying the –remote flag to git submodule update
--vault-id
the vault identity to use
--vault-password-file
vault password file
--verify-commit
verify GPG signature of checked out commit, if it fails abort running the playbook. This needs the corresponding VCS module to support such an operation
--version
show program’s version number and exit
-C <CHECKOUT>, --checkout <CHECKOUT>
branch/tag/commit to checkout. Defaults to behavior of repository module.
-K, --ask-become-pass
ask for privilege escalation password
-M, --module-path
prepend colon-separated path(s) to module library (default=[‘/root/.ansible/plugins/modules’, ‘/usr/share/ansible/plugins/modules’])
-T <TIMEOUT>, --timeout <TIMEOUT>
override the connection timeout in seconds (default=10)
-U <URL>, --url <URL>
URL of the playbook repository
-c <CONNECTION>, --connection <CONNECTION>
connection type to use (default=smart)
-d <DEST>, --directory <DEST>
directory to checkout repository to
-e, --extra-vars
set additional variables as key=value or YAML/JSON, if filename prepend with @
-f, --force
run the playbook even if the repository could not be updated
-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>
Repository module name, which ansible will use to check out the repo. Choices are (‘git’, ‘subversion’, ‘hg’, ‘bzr’). Default is git.
-o, --only-if-changed
only run the playbook if the repository has been updated
-s <SLEEP>, --sleep <SLEEP>
sleep for random interval (between 0 and n number of seconds) before starting. This is a useful way to disperse git requests
-t, --tags
only run plays and tasks tagged with these values
-u <REMOTE_USER>, --user <REMOTE_USER>
connect as this user (default=None)
-v, --verbose
verbose mode (-vvv for more, -vvvv to enable connection debugging)
