jgsqware / upgrade-check.yaml
Created November 6, 2020 13:25
# A popeye configuration file to check a
# Giant Swarm tenant cluster before upgrading.
#
# This configuration suppresses many useful checks for best practices that are also relevant
# in general, with the one goal: to highlight any details that could cause problems
# during an upgrade.
#
# Tested with popeye 0.9.0
#
# More about popeye: https://github.com/derailed/popeye
