# Utilising tini as our init system within the Docker container for graceful start-up and termination.
# Tini serves as an uncomplicated init system, adept at managing the reaping of zombie processes and forwarding signals.
# This approach is crucial to circumvent issues with unmanaged subprocesses and signal handling in containerised environments.
# By integrating tini, we enhance the reliability and stability of our Docker containers.
# Ensures smooth start-up and shutdown processes, and reliable, safe handling of signal processing.
