# This script uses openapi2jsonschema to generate a set of JSON schemas for
# the specified Kubernetes versions in different flavours:
#
#   X.Y.Z - URL referenced based on the specified GitHub repository
#   X.Y.Z-standalone - de-referenced schemas, more useful as standalone documents
#   X.Y.Z-standalone-strict - de-referenced schemas, more useful as standalone documents, additionalProperties disallowed
#   X.Y.Z-local - relative references, useful to avoid the network dependency
