Trying to copy a folders content, it works when i hard code the path like:
COPY ./my-folder /path/to/location
But need to be able to change this path so i tried using a build argument like this:
COPY ${folderVariable} /path/to/location
and then build with
--build-arg folderVariable=./my-folder
But it copies everything in the same folder as "my-folder", when i only want the contents of "my-folder"
You need to define it with ARG in Dockerfile before using:
FROM alpine:3.3
ARG folderVariable=./my-folder # Optional default value to be `./my-folder`
COPY ${folderVariable} /opt/my-folder
And build it like:
docker build --build-arg folderVariable=./folder-copy -t test .
More details please refer to: https://docs.docker.com/engine/reference/builder/#arg
