Pip install on lambic/lambda:python3.7 not working. #199

I am trying to understand how to pip install packages into the lambda using lambci/lambda While doing so, I created the below Dockerfile

FROM lambci/lambda:python3.7

ENV AWS_DEFAULT_REGION us-east-1

COPY . .

RUN pip3 install -r requirements.txt --user

# Assumes you have a .lambdaignore file with a list of files you don't want in your zip
RUN cat .lambdaignore | xargs zip -9qyr lambda.zip . -x

CMD aws lambda update-function-code --function-name mylambda --zip-file fileb://lambda.zip

But RUN pip3 install -r requirements.txt --user terminated with permission issues.

Check the permissions.

Any idea what am I missing. My goal is to be able to use some custom packages on lambda.

As per the README, you should be using a build image to install your dependencies (eg build-python3.7)
