Can't create a docker image for COPY failed: stat /var/lib/docker/tmp/docker-builder error

Question

I want to create a docker image. This is my work directory: Dockerfile.in test.json test.py

And this is my Dockerfile:

COPY ./test.json /home/tes         


        

Answer 1

The way docker look for file is from the current directory i.e. if your command is

COPY target/xyz.jar app.jar

ADD target/xyz.jar app.jar

The xyz jar should be in the current/target directory - here current is the place where you have your docker file. So if you have docker in a different dir. its better bring to main project directory and have a straight path to the jar being added or copied to the image.
