# render-candidate-catalog.sh creates a file-based OLM catalog containing the following:
#
# 1. The candidate shipwright-operator image (from a local/CI build)
# 2. The existing Tekton and Shipwright operators that are released on OperatorHub.io
#
# The core of the catalog are JSON manifests contained in `test/catalog`.
# This script copies those manifests to _output/catalog, then does a bit of opm and sed
# manipulation to create catalog entries for the candidate operator deployment.
