Docker Compose

FreeSWITCH

This container runs the lastest version of FreeSWITCH with vanilla config.

  freeswitch:
    hostname: freeswitch
    container_name: freeswitch
    image: ${DOCKER_REGISTRY-}freeswitch
    build:
      context: Voice/FreeSWITCH
      dockerfile: Dockerfile

Consumer Worker

This container runs the Consumer worker fetching the message from Kafka.

  calltracking.fsconsumerworker:
    image: ${DOCKER_REGISTRY-}calltrackingfsconsumerworker
    container_name: fs-consumer-worker
    build:
      context: .
      dockerfile: CallTracking.FSConsumerWorker/Dockerfile

Producer Worker

This container runs the Producer worker which is establishing an Inbound Socket connection to the FreeSWITCH container (ESL:8021). The worker is listening for all message and print Info log for each message received. Only Channel Answer message are sent to Kafka.

  calltracking.fsproducerworker:
    image: ${DOCKER_REGISTRY-}calltrackingfsproducerworker
    container_name: fs-producer-worker
    build:
      context: .
      dockerfile: CallTracking.FSProducerWorker/Dockerfile
    depends_on:
