How to COPY files of current directory to folder in Dockerfile

I’m trying to create a Dockerfile that copies all the files in the currently directory to a specific folder.

Currently I have

  • Multiple dokku apps one domain
  • Connect to Tornado app in Docker
  • Docker: How to curl local server xyz.example.com running on host machine from within a docker container
  • Docker unique container
  • error docker jhipster version 4.0.2
  • Docker: reattach to `docker exec` process
  • COPY . /this/folder
    

    I’m unable to check the results of this command, as my container closes nearly immediately after I run it. Is there a better way to test if the command is working?

  • Connect to mysql in a docker container from the host
  • How to retrain image on Windows
  • php-fpm Connection reset by peer
  • Connecting to a remote docker machine using publickey authentication from Windows
  • Convert Docker Compose to a service create command
  • Apply NetEM WAN delay on a docker container interface

    you can start a container and check.

    $ docker run -ti --rm <DOCKER_IMAGE> sh
    $ ls -l /this/folder
    

    If your docker image has ENTRYPOINT setting, then run below command:

    $ docker run -ti --rm --entrypoint sh <DOCKER_IMAGE>
    $ ls -l /this/folder
    

    If it is only for testing, include the below command in your docker file:

    RUN cd /this/folder && ls
    

    This will list the directory contents while docker build

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