    {"Id":"9a880dcbbbda","Warnings":["Your kernel does not support memory swap capabilities. Limitation discarded."]}
    

    And I tested if the container is running with sudo docker ps -l and showed that:

    ID                  IMAGE               COMMAND                CREATED             STATUS              PORTS
    9a880dcbbbda        base:latest         nc -l 8080    33 seconds ago      Exit 0

  • Run a service automatically in a docker container
  • One Solution collect form web for “how to run a daemon process in docker container with API/v1.5?”

    The result includes a warning, but it is just a warning, not an error.

    It means that your system cannot limit the memory or swap allocated to the container, and therefore, the container will run without the memory or swap limitation. But other than that, it should be running fine.

    Is there anything indicating that the container is not running correctly?

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
