XOS Containers
When deployed, XOS runs as a set of Docker containers that cooperate to provide platform controller functionality, including the data model, synchronizers, and northbound APIs. The following is an inventory of those containers:
| Name | Description | Internal Ports |
|---|---|---|
| xos-core | The core of the platform; responsible for maintaining the data model | 50051, 500515 |
| xos-db | A Postgres instance; used to persist the data model | 5432 |
| xos-redis | A Redis instance; used as pub/sub channel for internal notifications | 5432 |
| xos-tosca | Northbound TOSCA interface; accessible via REST | 9102 |
| xos-gui | Northbound GUI dashboard | 4000 |
| xos-ws | Listens to redis events and propagates them over web-sockets | 3000 |
| xos-chameleon | Northbound REST interface; accessible at /xosapi/v1/.. (swagger is published at /apidocs/ | 3000 |
| kafka | A Kafka bus; used by some backend components to send event notifications | 9092 |
All the communication between containers happen over gRPC except for xos-gui, which uses a combination of REST and web-socket.
Note: The dotted lines identify optional components that are required only in certain configurations.
