Redis Parser¶
- class django_docker_helpers.config.backends.redis_parser.RedisParser(endpoint='service', host='127.0.0.1', port=6379, db=0, path_separator='.', inner_parser_class=<class 'django_docker_helpers.config.backends.yaml_parser.YamlParser'>, **redis_options)[source]¶
Reads a whole config bundle from a redis key and provides the unified interface to access config options.
It assumes that config in your storage can be parsed with any simple parser, like
YamlParser
.Compared to, e.g.
EnvironmentParser
it does not have scope support by design, sinceendpoint
is a good enough scope by itself.Example:
parser = RedisParser('my/server/config.yml', host=REDIS_HOST, port=REDIS_PORT) parser.get('nested.a.b', coerce_type=int)
- Parameters
endpoint (
str
) – specifies a redis key with serialized config, e.g.'services/mailer/config.yml'
host (
str
) – redis host, default is'127.0.0.1'
port (
int
) – redis port, default id6379
db (
int
) – redis database, default is0
path_separator (
str
) – specifies which character separates nested variables, default is'.'
inner_parser_class (
Optional
[Type
[BaseParser
]]) – use the specified parser to read config fromendpoint
keyredis_options – additional options for
redis.Redis
client
- get(variable_path, default=None, coerce_type=None, coercer=None, **kwargs)[source]¶
Reads a value of
variable_path
from redis storage.- Parameters
variable_path (
str
) – a delimiter-separated path to a nested valuedefault (
Optional
[Any
]) – default value if there’s no object by specified pathcoerce_type (
Optional
[Type
]) – cast a type of a value to a specified onecoercer (
Optional
[Callable
]) – perform a type casting with specified callbackkwargs – additional arguments inherited parser may need
- Returns
value or default
- Raises
config.exceptions.KVStorageValueIsEmpty – if specified
endpoint
does not contain a config
- get_client()[source]¶
If your backend needs a client, inherit this method and use
client()
shortcut.- Returns
an instance of backend-specific client
- property inner_parser: django_docker_helpers.config.backends.base.BaseParser¶
Prepares inner config parser for config stored at
endpoint
.- Return type
- Returns
an instance of
BaseParser
- Raises
config.exceptions.KVStorageValueIsEmpty – if specified
endpoint
does not contain a config
