Orchestrating Telstar with Docker Compose

Example Docker Compose Yaml Files

The following docker-compose yaml file can be used to manage the Telstar application and associated mongo database.

   version: "3.8"
   services:
     telstar-01:
       container_name: "telstar-server"
       image: "johnnewcombe/telstar"
       command: "server --port 6512 --install" # install to the primary database
       ports:
         - target: 6512
           published: 6512
       networks:
         - telstar-network
       volumes:
         - type: volume
         source: telstar-volume
         target: /opt/telstar/volume
       depends_on:
         - mongodb
       environment:
         - TELSTAR_SERVER=AUSTEN
     mongodb:
       container_name: "telstar-mongo"
       image: "mongo"
       ports:
         - target: 27017
           published: 27017
       networks:
         telstar-network:
       environment:
         - MONGO_INITDB_ROOT_USERNAME=mongoadmin
         - MONGO_INITDB_ROOT_PASSWORD=secret
   networks:
     telstar-network:
       name: telstar-network
   volumes:
     telstar-volume:
       name: telstar-volume

The following docker-compose file starts three Telstar servers all talking to the same database server, however the third server (telstar-server-03) includes an environment variable that ensures that it uses the secondary database. This secondary database collection is typically used to test content before publishing it to the primary database collection. Further details of all of the available environment variables can be found in the section Configuration Options. In addition, the Telstar API is launched as a separate container.
