# This is a temporary stopgap to add some automation to the Googler-only process.
# In the long term, we want to develop a different process that non-Googlers
# can perform.
#
# It builds and pushes both Debian and Red Hat packages, pausing for
# confirmation before promoting each repo to stable. It always sets the
# package revision to 0, so you should only use it for a new minor or patch
# release for which packages have never been pushed.
#
# This is based on a copy of the existing script from ex-Googler
# mehdy@google.com, with some modifications to reduce the number of manual
# prompts, which can potentially derail a release if the wrong option is chosen
# by the user accidentally.
#
# Example usage:
#   git clone https://github.com/kubernetes/release.git
#   cd release
#   k8s-rapture.sh 1.6.12

# 3. Check if release repo up to date
# 4. Check if rpm and any other required command exists

# TODO(mehdy): Restructure the script into three phases:
# P1 - Building RPMs and DEBs
# P2 - Signing all packages
# P3 - Publish them.

# TODO(mehdy): Make the script rerunnable at any phase
