How and where the Streaming Media Service is deployed¶
The Streaming Media Service application is deployed using RPM packages. These are built by Gitlab CI in the Application Server repository. These can be copied to the Bes RPM package repository run by infra-sas@uis by following these instructions. As a last resort RPMs can be manually copied and installed.

Once the RPM packages are added to the Bes RPM package repository installation is simply a matter of running
zypper up as root.
