This file defines the schemas for the provider and requirer sides of this relation interface.
It must expose two interfaces.schema_base.DataBagSchema subclasses called:
- ProviderSchema
- RequirerSchema
TODO: see https://github.com/canonical/charm-relation-interfaces/issues/121
Index
class MimirClusterError
Description
Base class for exceptions raised by this module. None
class DataValidationError
Description
Raised when relation databag validation fails. None
class DatabagAccessPermissionError
Description
Raised when a follower attempts to write leader settings. None
class DatabagModel
Description
Base databag model. None
Methods
DatabagModel. load( cls , databag )
Description
Load this model from a Juju databag. None
DatabagModel. dump( self , databag , clear: bool )
Write the contents of this model to Juju databag.
Arguments
the databag to write the data to.
ensure the databag is cleared before writing it.
class DataBagSchema
Base class for relation interface databag schemas.
Description
Subclass from this base class and override "unit" and/or "app" to create a specification for a databag schema.
For example:
from pydantic import Json
class MyUnitConsumerSchema(DataBagSchema): foo: Json[int] bar: str
this class needs to be named "ConsumerSchema"
for it to be picked up by the automated tester.
class ConsumerSchema(DataBagSchema): unit: MyUnitConsumerSchema
This specifies that for a relation to satisfy MyRequirerSchema, the application databag needs to be empty and the unit databag needs to contain exactly a "bar":string and a "foo":Json-encoded int value.
By using pydantic's validator API, you can specify further constraints on the values, provide defaults, enforce encoding/decoding, and more.
class MimirRole
Description
Mimir component role names. None
def expand_roles(roles)
Description
Expand any meta roles to their 'atomic' equivalents. None
class MimirClusterProviderAppData
class ProviderSchema

class MimirClusterProvider
Methods

Description
Publish the mimir config and loki endpoints to all related mimir worker clusters. None
MimirClusterProvider. gather_roles( self )
Description
Go through the worker's app databags and sum the available application roles. None
MimirClusterProvider. gather_addresses_by_role( self )
Description
Go through the worker's unit databags to collect all the addresses published by the units, by role. None
MimirClusterProvider. gather_addresses( self )
