To start TEIV navigate to the 'docker-compose' directory in the 'teiv' repo and run 'docker-compose up'. This will bring up 3 Kafka containers, Zookeeper, PostgreSQL using PostGIS, TEIV Exposure, and TEIV Ingestion. The TEIV Ingestion and an optional kafka-producer service that will populate the database automatically, allowing you to query the database straight away.

If the kafka-producer isn't needed you can comment it out in the docker-compose.yml file. If commented out database won't be populated with any topology data, but the 'cloudEventProducer.sh' script in 'docker-compose/cloudEventProducer' can be used to populate the database with sample data that will enable querying of the database.

Sample API calls

To get a list of all API calls and details go to TEIV API docu mentation.

Collection: Query TEIV.postman_collection.json

Environment: TEIV.postman_environment.json

Schema for "Create classifiers and decorators schema": classifiers-and-decorators-module.yang

Retrieving and using topology modules

Topology & Inventory provides APIs to enable users to query module data that can be used to understand the existing topology and inventory model, parse the modules, and understand what objects are supported over the R1 interface, so adequate queries can be made on topology and inventory data.

The API endpoints returning lists support pagination. The default value for number of items returned is 500, which is also the upper limit.

Sample request to fetch a list of all modules related to the CLOUD domain:

To get a list of all modules for a specific domain, use a domain query parameter. The query parameter is case sensitive.

Note: - Partial matches are also supported in the query parameter using ’.*’ as a wild card. - If the specified domain does not exist, an empty list is returned.

Sample API calls

To get a list of all API calls and details go to TEIV API docu mentation.

To get a list of supported domains click here.

Postman collection

Collection: Query TEIV.postman_collection.json

Environment: TEIV.postman_environment.json

Retrieving and using topology modules

Topology & Inventory provides APIs to enable users to query module data that can be used to understand the existing topology and inventory model, parse the modules, and understand what objects are supported over the R1 interface, so adequate queries can be made on topology and inventory data.

The API endpoints returning lists support pagination. The default value for number of items returned is 500, which is also the upper limit.

Sample request to fetch a list of all modules related to the CLOUD domain:

To get a list of all modules for a specific domain, use a domain query parameter. The query parameter is case sensitive.

Note: - Partial matches are also supported in the query parameter using ’.*’ as a wild card. - If the specified domain does not exist, an empty list is returned.
