# This exec and entrypoint can be copied to another Lambda base image that
# already includes a language runtime (e.g. for Node.js, DotNet, etc.)

# The bootstrap exec is statically linked and does not depend on any shared
# libraries. It is built with the same CPU architecture as the host OS.
# It should run and invoke the `./bootstrap.sh` shell script
# which will start the desired app, such as `exec node index.js`.
