docker: Copy a file or directory from the host to a container, following symlinks (copies the symlinked files directly, not the symlinks themselves).

docker

$ docker cp --follow-link ${path-to-symlink_on_host} ${container_name}:${filename_or_directory_in_container}

try on your machine

The docker cp --follow-link command is used to copy files between the host machine and a running Docker container while also following symbolic links.

Here is a breakdown of the command arguments:

${path-to-symlink_on_host}: This is the path to the symbolic link on the host machine that you want to copy. It could be a file or a directory.

${container_name}: This is the name or ID of the target Docker container where you want to copy the file or directory.

${filename_or_directory_in_container}: This is the destination path inside the Docker container where you want to copy the file or directory.

By using the --follow-link option, the command will also follow symbolic links when copying the files. This means that if the symbolic link points to a file or directory, the actual target of the link will be copied instead of the link itself.

For example, if you have a symbolic link /host/symlink on the host machine that points to /host/file.txt, and you want to copy it into a container named mycontainer, you can use the command:

docker cp --follow-link /host/symlink mycontainer:/container/file.txt

This will copy the target file /host/file.txt into the directory /container inside the running container mycontainer. The --follow-link option ensures that the actual file contents of the target are copied, not the symbolic link itself.
