xApp onboarded to each RIC platform instance will need to learn the corresponding platform services endpoints. Today that includes RMR and DBAAS services.
The RIC platform injects the following environment parameters into the xApp containers. Note that the default values are only examples and depends on the RIC platform instance configuration they are subjected to change.
xApp should always refer to the environment variables for their values instead of using the default ones.
Environment Variable | Description | Default Value |
---|---|---|
RMR_RTG_SVC | 4561 | |
XAPP_DESCRIPTOR_PATH | Path of the xApp descriptor JSON file | /opt/ric/config |
DBAAS_MASTER_NAME | Entry point of DBAASHA sentinel | service-ricplt-dbaasha-sentinel.ricplt.svc.cluster.local |
DBAAS_SERVICE_HOST | Entry point of DBAAS service | service-ricplt-dbaasha-tcp.ricplt.svc.cluster.local (if using DBAASHA) service-ricplt-dbaas-tcp.ricplt.svc.cluster.local (if using DBAASSA) |
DBAAS_SERVICE_PORT | DBAAS service port | 6379 |
DBAAS_SERVICE_SENTINEL_PORT | DBAASHA sentinel port | 26379 |
How do xApp consume the parameters
The RMR and DBAAS parameters will be automatically picked up their corresponding libraries.
The xApp program can find the xApp descriptor file using XAPP_DESCRIPTOR_PATH. The descriptor should contains all the internal configuration parameters for the xApp.
