xApp onboarded to each RIC platform instance will need to learn the corresponding platform services endpoints. Today that includes RMR and DBAAS services.may have different parameters either provided by the operators in the xapp descriptor or by the RIC platform that the xApp is hosted upon.
These parameters are injected into the xApp container by using environment variables or by sharing the xApp descriptor file.
The following table shows the parameters that are injected as environment variables.
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- |
dbaas- |
tcp.ricplt.svc.cluster.local | ||
DBAAS_SERVICE_HOST | Entry point of DBAAS service | service-ricplt- |
dbaas-tcp.ricplt.svc.cluster.local |
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.
