Orchestrating Telstar with Docker Compose

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 TELSTAR server (telstar-server-03) uses the *secondary* database. This *secondary* database collection is typically used to test content before publishing it to the primary database collection. In addition the TELSTAR API is launced as a separate container.
