Working With Plugins
********************
Plugins are pieces of code that augment Ansible's core functionality. Ansible uses a plugin architecture to enable a rich, flexible and expandable feature set.
Ansible ships with a number of handy plugins, and you can easily write your own.
This section covers the various types of plugins that are included with Ansible:

Become plugins (#50991) * [WIP] become plugins Move from hardcoded method to plugins for ease of use, expansion and overrides - load into connection as it is going to be the main consumer - play_context will also use to keep backwards compat API - ensure shell is used to construct commands when needed - migrate settings remove from base config in favor of plugin specific configs - cleanup ansible-doc - add become plugin docs - remove deprecated sudo/su code and keywords - adjust become options for cli - set plugin options from context - ensure config defs are avaialbe before instance - refactored getting the shell plugin, fixed tests - changed into regex as they were string matching, which does not work with random string generation - explicitly set flags for play context tests - moved plugin loading up front - now loads for basedir also - allow pyc/o for non m modules - fixes to tests and some plugins - migrate to play objects fro play_context - simiplify gathering - added utf8 headers - moved option setting - add fail msg to dzdo - use tuple for multiple options on fail/missing - fix relative plugin paths - shift from play context to play - all tasks already inherit this from play directly - remove obsolete 'set play' - correct environment handling - add wrap_exe option to pfexec - fix runas to noop - fixed setting play context - added password configs - removed required false - remove from doc building till they are ready future development: - deal with 'enable' and 'runas' which are not 'command wrappers' but 'state flags' and currently hardcoded in diff subsystems * cleanup remove callers to removed func removed --sudo cli doc refs remove runas become_exe ensure keyerorr on plugin also fix backwards compat, missing method is attributeerror, not ansible error get remote_user consistently ignore missing system_tmpdirs on plugin load correct config precedence add deprecation fix networking imports backwards compat for plugins using BECOME_METHODS * Port become_plugins to context.CLIARGS This is a work in progress: * Stop passing options around everywhere as we can use context.CLIARGS instead * Refactor make_become_commands as asked for by alikins * Typo in comment fix * Stop loading values from the cli in more than one place Both play and play_context were saving default values from the cli arguments directly. This changes things so that the default values are loaded into the play and then play_context takes them from there. * Rename BECOME_PLUGIN_PATH to DEFAULT_BECOME_PLUGIN_PATH As alikins said, all other plugin paths are named DEFAULT_plugintype_PLUGIN_PATH. If we're going to rename these, that should be done all at one time rather than piecemeal. * One to throw away This is a set of hacks to get setting FieldAttribute defaults to command line args to work. It's not fully done yet. After talking it over with sivel and jimi-c this should be done by fixing FieldAttributeBase and _get_parent_attribute() calls to do the right thing when there is a non-None default. What we want to be able to do ideally is something like this: class Base(FieldAttributeBase): _check_mode = FieldAttribute([..] default=lambda: context.CLIARGS['check']) class Play(Base): # lambda so that we have a chance to parse the command line args # before we get here. In the future we might be able to restructure # this so that the cli parsing code runs before these classes are # defined. class Task(Base): pass And still have a playbook like this function: --- - hosts: tasks: - command: whoami check_mode: True (The check_mode test that is added as a separate commit in this PR will let you test variations on this case). There's a few separate reasons that the code doesn't let us do this or a non-ugly workaround for this as written right now. The fix that jimi-c, sivel, and I talked about may let us do this or it may still require a workaround (but less ugly) (having one class that has the FieldAttributes with default values and one class that inherits from that but just overrides the FieldAttributes which now have defaults) * Revert "One to throw away" This reverts commit 23aa883cbed11429ef1be2a2d0ed18f83a3b8064. * Set FieldAttr defaults directly from CLIARGS * Remove dead code * Move timeout directly to PlayContext, it's never needed on Play * just for backwards compat, add a static version of BECOME_METHODS to constants * Make the become attr on the connection public, since it's used outside of the connection * Logic fix * Nuke connection testing if it supports specific become methods * Remove unused vars * Address rebase issues * Fix path encoding issue * Remove unused import * Various cleanups * Restore network_cli check in _low_level_execute_command * type improvements for cliargs_deferred_get and swap shallowcopy to default to False * minor cleanups * Allow the su plugin to work, since it doesn't define a prompt the same way * Fix up ksu become plugin * Only set prompt if build_become_command was called * Add helper to assist connection plugins in knowing they need to wait for a prompt * Fix tests and code expectations * Doc updates * Various additional minor cleanups * Make doas functional * Don't change connection signature, load become plugin from TaskExecutor * Remove unused imports * Add comment about setting the become plugin on the playcontext * Fix up tests for recent changes * Support 'Password:' natively for the doas plugin * Make default prompts raw * wording cleanups. ci_complete * Remove unrelated changes * Address spelling mistake * Restore removed test, and udpate to use new functionality * Add changelog fragment * Don't hard fail in set_attributes_from_cli on missing CLI keys * Remove unrelated change to loader * Remove internal deprecated FieldAttributes now * Emit deprecation warnings now
