cobald.daemon.core.config module

class cobald.daemon.core.config.COBalDLoader(stream)

Bases: SafeLoader

Loader with access to COBalD configuration constructors

class cobald.daemon.core.config.PipelineTranslator

Bases: Translator

Translator for cobald pipelines

This allows for YAML configurations to have one or several pipeline elements. Each pipeline is translated as a series of nested elements, the way a Controller receives a Pool.

pipeline:
    # same as ``package.module.callable(a, b, keyword1="one", keyword2="two")
    - __type__: package.module.Controller
      interval: 20
    - __type__: package.module.Pool

translate_hierarchy(structure, *, where='', **construct_kwargs)

cobald.daemon.core.config.add_constructor_plugins(entry_point_group: str, loader: Type[BaseLoader]) → None

Add PyYAML constructors from an entry point group to a loader

Parameters:

• loader – the PyYAML loader which uses the plugins
