Sources should have a unique label. This will help tracing where your
configurations are coming from if you turn up the log-level.
The keyword arguments are significant. Different sources require
different keyword arguments. Required keys for each source_type are
listed below, for a detailed list of all possible arguments, see the
individual source's documentation.
source_type: dict
required keyword arguments:
- data - A dictionary
source_type: environment
No required keyword arguments.
source_type: etcd
required keyword arguments:
- client - A client from the python-etcd package.
source_type: json
required keyword arguments:
- filename - A JSON file.
- data - A string representation of JSON
source_type: kubernetes
required keyword arguments:
- client - A client from the kubernetes package
- name - The name of the ConfigMap to load
source_type: yaml
required keyword arguments:
- filename - A YAML file.
Args:
label (str): A label for the source.
source_type (str): A source type, available source types depend
on the packages installed. See ``yapconf.ALL_SUPPORTED_SOURCES``
