# Define the entrypoint of the container. Passing arguments (known as the COMMAND) when running the
# container will be passed as arguments to the function. Ultimately what is executed is the ENTRYPOINT concatenated
# with the COMMAND. You may add custom options to ENTRYPOINT but note that those options will always be set when
# running in AWS.
