I am trying to copy content of a directory while creating the docker image in the Dockerfile but while copying its giving me error-
COPY failed: stat /var/lib/docker/tmp/docker-builder108255131/Users/user_1/media : no such file or directory
I have the following file in the Dockerfile-
COPY /Users/user_1/media/. /code/project_media/ The media directory is in a seperate directory level then Dockerfile.
Sorry per dockerfile documentation:
Multiple resources may be specified but the paths of files and directories will be interpreted as relative to the source of the context of the build
https://docs.docker.com/engine/reference/builder/#copy
I usually will have a script for building the docker, and in that script will copy the files need for the COPY command into either the same directory or sub-directory of the "context of the build" (a very confusing way of saying the same directory as the dockerfile is in)
DOCKER_BUILD_DIR="./build/docker" DOCKERFILE="./docker/Dockerfile" MEDIA_FILES="/Users/user_1/media" mkdir -p "${DOCKER_BUILD_DIR}/${MEDIA_FILES}" cp -f "${DOCKERFILE}" "${DOCKER_BUILD_DIR}/" cp -rf "${MEDIA_FILES}" "${DOCKER_BUILD_DIR}/${MEDIA_FILES}/.." docker build "${DOCKER_BUILD_DIR}" 
COPYd into a Docker image must be in the same directory tree as the Dockerfile. You cannot COPY from an arbitrary place on disk.
docker build command. The command is docker build [OPTIONS] PATH | URL | - where PATH | URL | - is your "Context of the Build." If you are just looking at the "Dockerfile" reference, then it is confusing to me...
