Updated at March 3, 2025
To configure the service components, provide each setting in the respective environment variable in the --env parameter of the command to run the component's Docker container:
docker run --it \
--env <setting_1>=<value> \
--env <setting_2>=<value> \
... \
<container_name>
If you run containers using the docker compose command, add or edit the service's description settings in the environment section of the docker-compose.yaml file.

Run component command example
The example assumes that the license server runs on host 172.10.19.12 with port 8083 to register an STT application. To run the STT server, use this command:
docker run -it \
--env LICENSE_SERVICE_ENDPOINTS=172.10.19.12:8083 \
--env SERVICE_PORT=17019 \
cr.yandex/<registry_ID>/stt/cpu_x86_64/stt_server:<STT_application_version>
Where:
<registry_ID>: Registry with Docker images for deployment of SpeechKit Hybrid components.<STT_application_version>: Provided STT version.
