CMS Sao

A microservice that orbits around CMS exposing the Entry, Result, Score and Scoreboard entities as REST resources.

Up and running

CMS Sao can be deployed and run as a Docker container or a standalone binary; either way is recommend to run this application as the former one.

Prerequisites

CMS Sao heavily relies on CMS including its database, so in order to have this application up and running you will need:

1. CMS 1.3.x or greater (the current Sao version was designed against the last CMS revision in January 2018)
2. CMS PostreSQL DB schema access (it could be the same credentials that CMS uses but is not recommended)
3. MongoDB as temporal storage and message queue
4. Docker engine 17.x or greater

Deployment

CMS Sao can be deployed and run as a Docker container, it can be done directly using docker container run command:

docker container run -p 8000:8000 cmsorbits/cms-sao

Or it can be run using docker-compose up with a docker-compose.yml file similar to the one on the project root.

Configuration

All the intrinsic configurations can be overridden via the config.properties file in Sao's working directory (you could use config.properties.example as guide) or as environment variables with the SAO_ prefix. As for example in order to override the datasource.host value, you could start the Docker container with the following syntax:

docker container run -p 8000:8000 -e 'SAO_CMS_DATASOURCE_HOST=10.10.37.10' cmsorbits/cms-sao

When CMS Sao is executed using docker-compose the override values can be provided directly in the docker-compose.yml or docker-compose.override.yml files (within the environment section).

The most relevant properties are:

Property name	Default value	Description
server.port	8000	The port where the application will listen for incoming requests
server.log.request	false	When set as true the application will log each incoming request to the STDOUT
server.error.tracedump	false	When set as true the application will include the error trace in failure responses
