SYNOPSIS
|
|
|
|
|
--------
|
|
|
|
|
ansible-pull -d DEST -U URL [options] [ <filename.yml> ]

DESCRIPTION
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
*Ansible* is an extra-simple tool/framework/API for doing \'remote things' over
|
|
|
|
|
SSH.
|
|
|
|
|
|
|
|
|
|
Use ansible-pull to set 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.

|
|
|
*filename.yml*::

|
|
|
|
|
|
|
|
|
The name of one the YAML format files to run as an ansible playbook. This can
|
|
|
|
|
be a relative path within the checkout. If not provided, ansible-pull
|
|
|
|
|
will look for a playbook based on the host's fully-qualified domain name, on the
|
|
|
|
|
host hostname and finally a playbook named *local.yml*.
|
|
|
|
|

Don't disable GSSAPI/Pubkey authentication when using --ask-pass
This commit is based on a bug report and PR by kolbyjack (#6846) which
was subsequently closed and rebased as #11690. The original problem was:
«The password on the delegated host is different from the one I
provided on the command line, so it had to use the pubkey, and the
main host doesn't have a pubkey on it yet, so it had to use the
password.»
(This commit is revised and included here because #11690 would conflict
with the changes in #11908 otherwise.)
Closes #11690

Be more explicit about why SSH arguments are added
This adds vvvvv log messages that spell out in detail where each SSH
command-line argument is obtained from.
Unfortunately, we can't be sure if, say, self._play_context.remote_user
is obtained from ANSIBLE_REMOTE_USER in the environment, remote_user in
ansible.cfg, -u on the command line, or an ansible_ssh_user setting in
the inventory or on a task or play. In some cases, e.g. timeout, we
can't even be sure if it was set by the user or just a default.
Nevertheless, on the theory that at five v's you can use all the hints
available, I've mentioned the possible sources in the log messages.
Note that this caveat applies only to the arguments that ssh.py adds by
itself. In the case of ssh_args and ssh_extra_args, we know where they
are from, and say so, though we can't say WHERE in the inventory they
may be set (e.g. in host_vars or group_vars etc.).

Allow ansible_ssh_args to be set as an inventory variable
Before this change, ssh_args could be set only in the [ssh_connection]
section of ansible.cfg, and was applied to all hosts. Now it's possible
to set ansible_ssh_args as an inventory variable (directly, or through
group_vars or host_vars) to selectively override the global setting.
Note that the default ControlPath settings are applied only if ssh_args
is not set, and this is true of ansible_ssh_args as well. So if you want
to override ssh_args but continue to set ControlPath, you'll need to
repeat the appropriate options when setting ansible_ssh_args.
(If you only need to add options to the default ssh_args, you may be
able to use the ansible_ssh_extra_args inventory variable instead.)

Allow overriding ansible_ssh_extra_args on the command-line
This patch makes it possible to do:
ansible somehost -m setup \
--ssh-extra-args '-o ProxyCommand="ssh -W %h:%p -q user@bouncer.example.com"'
This overrides the inventory setting, if any, of ansible_ssh_extra_args.
Based on a patch originally by @Richard2ndQuadrant.

Add an ansible_ssh_extra_args inventory variable
This can be used to configure a per-host or per-group ProxyCommand to
connect to hosts through a jumphost, e.g.:
inventory:
[gatewayed]
foo ansible_ssh_host=192.0.2.1
group_vars/gatewayed.yml:
ansible_ssh_extra_args: '-o ProxyCommand="ssh -W %h:%p -q bounceuser@gateway.example.com"'
Note that this variable is used in addition to any ssh_args configured
in the [ssh_connection] section of ansible.cfg (so you don't need to
repeat the ControlPath settings in ansible_ssh_extra_args).

|
|
|
|
|
|
|
|
|

Add the specified arguments to any ssh command-line. Useful to set a
|

ProxyCommand to use a jump host, but any arguments may be specified.

|
|
|
|
|
|
*-t* 'TAGS', *--tags=*'TAGS'::
|
|
|
|
|
|
|
|
|
|
Only run plays and tasks tagged with these values.
|
|
|
|
|
|
|
|
|
|
*-U* 'URL', *--url=*'URL'::
|
|
|
|
|
|
|
|
|
|
URL of the playbook repository to checkout.
|
|
|
|
|
|
|
|
|

*--vault-password-file=*'VAULT_PASSWORD_FILE'::
|
|
|
|
|
|
|
|
|
|
Vault password file.
