Answer 1

The APP folder does not exist in your project

You are trying to add an APP folder that does not exist into your docker container and it is complaining because there is no APP folder to add into the container

In the line

COPY ./APP /APP

The ./APP must reflect a folder that is in your project

Answer 2

maybe IDE ‘s fault
check you’ve not added it to .dockerignore file.

Answer 3

Another reason may be the files/folder you are trying to copy are not in the docker context. Make sure that if Dockerfile is present inside some subdirectory of parent directory e.g. parent-dir/child-dir/Dockerfile , run the docker build command from parent directory instead as below

docker build -f parent-dir/child-dir/Dockerfile -t image .
