    Why are you creating a logging file inside the container? Configuring a logging driver would be more flexible.

    The following example is contrived, but demonstrates how logging events from all your containers could be collected. I suggest reading further into the options available from fluentd

    Example

    First run fluentd within a container to collect log events

    mkdir log
    docker run -d --name fluentd -p 24224:24224 -v $PWD:/fluentd/etc -v $PWD/log:/fluentd/log -e FLUENTD_CONF=log.conf fluent/fluentd
    

    Now run a container that creates an event to be logged:

    docker run --log-driver=fluentd ubuntu echo hello world
    

    The sample configuration sends log events to an output log file

    ├── log
    │   └── events.20160901.b53b670f22298bbcb
    └── log.conf
    

    log.conf

    
      @type  forward
      port  24224
    
    
    
       @type file
       path         /fluentd/log/events
       append       true
    
    

    Additional

    Are you married to the Oracle JDK? The following Dockerfile would be considerable simpler:

    FROM openjdk:8
    ADD target/demo-1.0.jar /opt/demo/demo-1.0.jar
    CMD ["java","-jar","/opt/demo/demo-1.0.jar"]
