# This script generates the Github Release page and uploads all the binaries/etc to that page
# This is intended to be run on a new release tag in order to generate the github release page for that release

# The script expects the following env variables:
# VERSION_MAJOR: The major version of the tag to be released.
# VERSION_MINOR: The minor version of the tag to be released.
# VERSION_BUILD: The build version of the tag to be released.
# ISO_SHA256: The sha 256 of the minikube-iso for the current release.
# GITHUB_TOKEN: The Github API access token. Injected by the Jenkins credential provider.
