# How to run this example
# 1 - Build the docker image by running the command "docker build -t fsouza/fake-gcs-server ."
# 2 - Start the docker container: "docker run -d --name fake-gcs-server -p 4443:4443 -v ${PWD}/examples/data:/data fsouza/fake-gcs-server -scheme http"
# 3 - Check if it's working by running: "curl http://0.0.0.0:4443/storage/v1/b"
# 4 - Create a python virtual environment (Ex: python -m .venv venv)
