It (HTTP) expose a local iso image and boots a BMC server with that iso using Redfish protocol

redfish_boot_iso.sh

# !/bin/bash

#################################
# Very simple script that exposes a local iso image
# and boots a BMC virtual media pointing to it.
# It uses a Redfish Interface
# It uses a python simple http server to expose the image
# The server runs on port 7800
################################
# The script is very simple and lacks of making
# many tests, so it just runs all the commands
# it would need some user extra checks
