Murano Data Source Driver¶
https://blueprints.launchpad.net/congress/+spec/murano-driver
This blueprint is to add a data source driver for Murano
Problem description¶
We need a data source to get the Murano environments and applications related data so that we can define policies during and after application service fulfillment
Proposed change¶
Add data source driver that integrates Congress with Murano with following data tables.
Data Tables
murano:objects(object_id, owner_id, type)
This table holds every MuranoPL object instance in an environment.
object_id - uuid of the object as used in Murano
owner_id - uuid of the owner object as used in Murano
type - string with full type identification as used in Murano (e.g., io.murano.Environment,…)
murano:parent-types(id, parent_type)
This table holds parent types of obj_id object.
id - uuid of the object as used in Murano
parent_type - string with full type identification of the parent object
Note that Murano supports multiple inheritance, so there can be several parent types for one object
murano:properties(id, name, value)
This table stores object’s properties. For multiple cardinality properties, there can be number of records here.
id - uuid of the object as used in Murano
name - property name
value - property value
MuranoPL properties referencing class type (i.e., another object) are stored in murano:relationship. Properties with structure has not direct mapping here - it has to be stored here component by component.
murano:relationships(source_id, target_id, name)
This table stores relationship between objects (i.e., MuranoPL property to class).
source_id - uuid of the source object
target_id - uuid of the target object
name - name of the relationship between source and target object
For multiple cardinality relationships there is several records in the table.
murano:states(id, state)
This table stores EnvironmentStatus of Murano environment
id - uuid of the environment
state - the state status of the environment
The state status will be one of ‘READY’, ‘PENDING’, ‘DEPLOYING’, ‘DEPLOY_FAILURE’, ‘DELETING’, ‘DELETE_FAILURE’.
Alternatives¶
N/A
Policy¶
We will have pre and post deployment policies for Murano applications based on the data tables defined in the driver.
Pre deployment policies will cover policies during application service fulfillment and will leverage the Congress simulate feature.
Post deployment policies will cover monitoring policies on fulfilled service instances.
Policy actions¶
Actions will be added in the second phase.
