Dockerfile

# Simple Dockerfile to demonstrate the use of the multiarch on native architecture.
# This Dockerfile is based on the latest Alpine Linux image.
# The `uname` command is used to display system information.

# This command will echo the system information using `uname -a`, a hello world message, and the current date and time to stdout, then exit cleanly.
