ansible-pull¶
pulls playbooks from a VCS repo and executes them for the local host
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)
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=[‘/nonexistent/.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
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)
