class Plugin(object):
"""A Beer-garden Plugin
This class represents a Beer-garden Plugin - a continuously-running process
that can receive and process Requests.
To work, a Plugin needs a Client instance - an instance of a class defining
which Requests this plugin can accept and process. The easiest way to define
a ``Client`` is by annotating a class with the ``@system`` decorator.
A Plugin needs certain pieces of information in order to function correctly. These
can be grouped into two high-level categories: identifying information and
connection information.
Identifying information is how Beer-garden differentiates this Plugin from all
other Plugins. If you already have fully-defined System model you can pass that
directly to the Plugin (``system=my_system``). However, normally it's simpler to
pass the pieces directly:
- ``name`` (required)
- ``version`` (required)
- ``instance_name`` (required, but defaults to "default")
- ``namespace``
- ``description``
- ``icon_name``
- ``metadata``
- ``display_name``
Connection information tells the Plugin how to communicate with Beer-garden. The
most important of these is the ``bg_host`` (to tell the plugin where to find the
Beer-garden you want to connect to):
- ``bg_host``
- ``bg_port``
- ``bg_url_prefix``
- ``ssl_enabled``
- ``ca_cert``
- ``ca_verify``
- ``client_cert``
An example plugin might look like this:
.. code-block:: python
Plugin(
name="Test",
version="1.0.0",
instance_name="default",
namespace="test plugins",
description="A Test",
bg_host="localhost",
)
Plugins use `Yapconf <https://github.com/loganasherjones/yapconf>`_ for
configuration loading, which means that values can be discovered from sources other
than direct argument passing. Config can be passed as command line arguments::
python my_plugin.py --bg-host localhost
Values can also be specified as environment variables with a "\\BG_" prefix::
BG_HOST=localhost python my_plugin.py
Plugins service requests using a
:py:class:`concurrent.futures.ThreadPoolExecutor`. The maximum number of
threads available is controlled by the ``max_concurrent`` argument.
.. warning::
Normally the processing of each Request occurs in a distinct thread context. If
you need to access shared state please be careful to use appropriate
concurrency mechanisms.
.. warning::
The default value for ``max_concurrent`` is 5, but setting it to 1 is allowed.
This means that a Plugin will essentially be single-threaded, but realize this
means that if the Plugin invokes a Command on itself in the course of processing
a Request then the Plugin **will** deadlock!
Args:
client: Instance of a class annotated with ``@system``.
bg_host (str): Beer-garden hostname

authority that issued the Beer-garden server certificate
ca_verify (bool): Whether to verify Beer-garden server certificate

Beer-garden. NOTE: This is required to be a cert / key bundle if SSL/TLS is
enabled for rabbitmq in your environment.
client_key (str): Path to client key. Not necessary if client_cert is a bundle.
api_version (int): Beer-garden API version to use
client_timeout (int): Max time to wait for Beer-garden server response
username (str): Username for Beer-garden authentication

description (str): System description
display_name (str): System display name
icon_name (str): System icon name
max_instances (int): System maximum instances
metadata (dict): System metadata
instance_name (str): Instance name
namespace (str): Namespace name
logger (:py:class:`logging.Logger`): Logger that will be used by the Plugin.
Passing a logger will prevent the Plugin from preforming any additional
logging configuration.
worker_shutdown_timeout (int): Time to wait during shutdown to finish processing
max_concurrent (int): Maximum number of requests to process concurrently
max_attempts (int): Number of times to attempt updating of a Request
before giving up. Negative numbers are interpreted as no maximum.
max_timeout (int): Maximum amount of time to wait between Request update
attempts. Negative numbers are interpreted as no maximum.
starting_timeout (int): Initial time to wait between Request update attempts.
Will double on subsequent attempts until reaching max_timeout.
mq_max_attempts (int): Number of times to attempt reconnection to message queue
before giving up. Negative numbers are interpreted as no maximum.
mq_max_timeout (int): Maximum amount of time to wait between message queue
reconnect attempts. Negative numbers are interpreted as no maximum.
mq_starting_timeout (int): Initial time to wait between message queue reconnect
attempts. Will double on subsequent attempts until reaching mq_max_timeout.
working_directory (str): Path to a preferred working directory. Only used
when working with bytes parameters.
