Default Docker entrypoint

I am creating an image from another image that set a specific entrypoint. However I want my image to have default one. How do I reset the ENTRYPOINT?

I tried the following Dockerfile:

  • Docker exits with a exit code on starting
  • Could not run Calabash-android on docker
  • Running YARN cluster in Kubernetes/Mesos
  • is there a way to negate a pattern in .dockerignore?
  • running incorrect docker image osx
  • Moving a Docker node to a different Azure account
  • FROM some-image
    ENTRYPOINT ["/bin/sh", "-c"]

    Unfortunately it doesn’t work like the default entrypoint as it need the command to be quoted.

    docker run myimage ls -l /    # "-l /" arguments are ignored
    file1 file2 file3             # files in current working directory
    docker run myimage "ls -l /"  # works correctly

    How do I use commands without quoting?

  • Sinatra app on AWS Beanstalk with docker and SQS
  • Need cq-quickstart-6.1.0-SNAPSHOT.jar file
  • Docker Networking: Auto-discovering host names in a bridge network
  • How does a Docker engine replace a hypervisor and guest OS?
  • Build Docker image for ARM architecture on Intel machine (Mac)
  • docker-compose does not override a command using the start command

    To disable an existing ENTRYPOINT, set an empty array in your docker file


    Then your arguments to docker run will exec as normal.

    The reason your ENTRYPOINT ["/bin/sh", "-c"] requires quoted strings is that without the quotes, the arguments to ls are being passed to sh instead.

    Unquoted results in lots of arguments to sh

    "/bin/sh", "-c", "ls", "-l", "/"

    Quoting allows the complete command (-c) to be passed to sh

    "/bin/sh", "-c", "ls -l /"
    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
