# This script builds all the minikube binary for all 3 platforms as well as Windows-installer and .deb
# This is intended to be run on a new release tag in order to build/upload the required files for a 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.
# BUCKET: The GCP bucket the build files should be uploaded to.
# GITHUB_TOKEN: The Github API access token. Injected by the Jenkins credential provider.
