How to copy folder from parent into current directory for Dockerfile using Makefile - docker

Question

I have a makefile that looks like this:
push:
docker build -t dataengineering/dataloader .
docker tag dataengineering/dataloader:latest 127579856528.dkr.ecr.us-west-2.amazonaws.com/dataengineering/dataloader:latest
docker push 127579856528.dkr.ecr.us-west-2.amazonaws.com/dataengineering/dataloader:latest
deploy:
#if [ ! "$(environment)" ]; then echo "environment must be defined" && exit 1; fi
#if [ ! "$(target)" ]; then echo "target must be defined" && exit 1; fi
kubectl delete deploy dataloader-$(target) -n dataengineering|| continue
kubectl apply -f kube/$(environment)/deployment-$(target).yaml -n dataengineering
But I need a folder inside the dataloader in order for my dockerfile to actually work.
Does this work?
push:
cd ..; cp -r datastore/ dataloader/
docker build -t dataengineering/dataloader .
docker tag dataengineering/dataloader:latest 1111111111.dkr.ecr.us-west-2.amazonaws.com/dataengineering/dataloader:latest
docker push 11111111111.dkr.ecr.us-west-2.amazonaws.com/dataengineering/dataloader:latest
deploy:
#if [ ! "$(environment)" ]; then echo "environment must be defined" && exit 1; fi
#if [ ! "$(target)" ]; then echo "target must be defined" && exit 1; fi
kubectl delete deploy dataloader-$(target) -n dataengineering|| continue
kubectl apply -f kube/$(environment)/deployment-$(target).yaml -n dataengineering
My dockerfile:
FROM python:3.7
WORKDIR /var/dataloader
COPY assertions/ ./assertions/
...
COPY datastore/ ./datastore/
RUN pip3 install -r requirements.txt
ENTRYPOINT ["python", "dataloader.py"]

If all you need is to copy the directory into the current directory (which would server as your Docker context), you can use cp -r ../datastore/ dataloader/. Unless you want the dataloader directory to be in the same directory as the datastore directory, then you'd do cp -r ../datastore/ ../dataloader/.
