Save the output dataframe from docker to a local machine

Question

Tried with {WORKDIR} & replaced {ADD} with {COPY} in Dockerfile. Still the CSV file is not being saved in the local folded in the local machine, why is this?

Answer 1

In order to write to a host file from the Docker container, first volume mount a directory into the running container.

For example, we can mount the current working directory into a directory in the container:

$ docker run -v $(PWD):/pwd_in_container -it --rm busybox touch /pwd_in_container/test

Then the file we created in the container will be available on the host:

$ ls test
test
