To install docker toolbox follow the following steps: Go to Docker Toolbox Click the link for Windows and run the installer. To Verify Installation: 1. Click the icon to launch a Docker Toolbox terminal. Once the terminal is open type If all is well then this should print a welcome message verifying that the installation was successful.

If it's not, install it before proceeding. Sign in to your existing Docker Hub account, or sign up for a new account. Download the Docker Desktop software. Double-click Docker for Windows Installer to run it. On the Configuration dialog box of the installer, you will be prompted on whether Docker should use Windows containers.

Close the installer when it has completed. Click the Docker Desktop button in the Start menu to start Docker. First, we can use the Unix cp command, which has many more flags and options over the docker cp command. The second advantage is that we can create a single shared directory for all Docker containers. This means we can copy directly between containers as long as they all have the same volume mount. Keep in mind this approach has the disadvantage that all files have to go through the volume mount.

This means we cannot copy files in a single command. Instead, we first copy files into the mounted directory, and then into their final desired location. Another drawback to this approach is we may have issues with file ownership. Docker containers typically only have a root user, which means files created inside the container will have root ownership by default.

We can use the Unix chown command to restore file ownership if needed on the host machine. Dockerfiles are used to build Docker images, which are then instantiated into Docker containers.

Dockerfiles can contain several different instructions, one of which is COPY. The COPY instruction lets us copy a file or files from the host system into the image. This means the files become a part of every container that is created from that image. Just like the other copy commands, SRC can be either a single file or a directory on the host machine. It can also include wildcard characters to match multiple files.

The main downside of this approach is that we cannot use it for running Docker containers. Docker images are not Docker containers, so this approach only makes sense to use when the set of files needed inside the image is known ahead of time. In this tutorial, we've seen how to copy files to and from a Docker container.
