sudo docker pull amazonlinux
sudo docker run -it amazonlinux:latest /bin/bash

# inside container
yum -y install python37 zip
python3 -m venv python
source python/bin/activate
pip3 install matplotlib
deactivate 
rm -rf python/{bin,include,lib64,pyvenv.cfg} python/lib/python3.7/site-packages/{__pycache__,easy_install.py,numpy*,pip*,pkg_resources,setuptools*}
zip -r aws_lambda_python37_layer_matplotlib.zip python/

# in other terminal, copy file from container to host
CONTAINER_ID=$(sudo docker ps|grep amazonlinux|cut -d " " -f1)
sudo docker cp ${CONTAINER_ID}:/aws_lambda_python37_layer_matplotlib.zip .

# exit container
exit

Thanks, this helped me a lot. In case someone else is trying to run this on Apple Silicon, make sure to set the --platform parameter so that pip3 install installs the binaries for the correct architecture:

docker run --platform linux/amd64 -it amazonlinux:latest /bin/bash
