Docker Copy is a directive or instruction that is used in a Dockerfile to copy files or directories from local machine to the container filesystem where the source is the local path and destination is the path in the container filesystem. Something like this: /a/b/c/Dockerfile: FROM base ADD ../b/file.txt. -chown parameter is supported when buiding Dockerfile for Linux containers, it does not work on Windows containers. In this example, your shared context dir is the runtime dir. Description On Windows, using Docker Compose V2, volumes specified using a relative path are not correctly mounted. The second technique is to use the docker cp command. The COPY instruction copies new files or directories from <src> and adds them to the filesystem of the container at the path <dest>.. Copy files while replacing the variables contained in them. Facebook. The <src> path must be inside the context of the build; you cannot COPY ../something /something, because the first step of a docker build is to send the context directory (and subdirectories) to the docker daemon. Note that the COPY instruction takes a path, relative to the build context as argument, not a drive-letter and an absolute path; the Web\WebUI directory should thus be present in the directory from which you start the build (which is used as build-context).
