how do i copy multiple files using docker?

Copying multiple files using Docker can be a complex and tedious process, especially if you're trying to copy from one location to another within the same image. Fortunately, there are a variety of ways to accomplish this task and make copying multiple files with Docker quick, easy, and efficient.

The first, and perhaps most straightforward method for copying multiple files with docker is to use 'docker cp' command. This command allows the user to copy files or folders from the local filesystem into a running container. To utilize this command you will need to provide two paths - one for the source file(s) you wish to copy and one as the destination within the container. Both of these paths must include the full directory structure needed in order to locate them properly.

For example:

docker cp /home/user/files/source /destination/in/container

Once your two paths have been provided, your files will be copied successfully onto your desired destination folder in your container.

Another option for copying multiple files into Docker is by using 'docker archive' command. This approach allows you to create an archive file from either a local filesystem or from within an existing container and then transfer it through other commands like 'docker load' or even SSH (Secure Shell) into another container location. The advantage of using this technique is that it uses less disk space compared to docker cp since you are creating an archive or "tarball" type file which can be compressed on a number of levels depending upon its content. Furthermore, any user accessing the private file(s) inside this archive must ensure that he has been granted access from outside sources before gaining access inside; thereby adding an extra layer of security while transferring information between containers.

Finally, if neither of these methods suit your needs, some users may also opt for simply mounting their desired folder as a volume directly on their base image - all interactions between two things related through such "volume mountings" are visible both externally in real time as well as internally after any manual changes have been made via direct access inside the volume itself which makes things much simpler than dealing with individual archives or individual small files being transferred between large databases (for example). However, mounting additional volumes requires more resources not only in terms of actual hosting but also due to security issues related closely with it and so it might not always be feasible if you are looking for portability from container-to-container transfers between different hosts sometimes located far away from each other or across various networks or clouds etc..
