# This script takes the current operator version from the last generated csv and generates:
# - operator bundle image
# - operator index image
# - CR CatalogSource to be applied on openshift
# It needs:
# - yq (https://github.com/mikefarah/yq)
# - container tool (docker|podman)
# - operator-sdk (https://sdk.operatorframework.io/docs/installation/)
# - opm (https://docs.openshift.com/container-platform/4.7/cli_reference/opm-cli.html#opm-cli)
# - container registry (registry.hub.docker.com|docker.io)
# For typical use:
#  OPM_CONTAINER_TOOL=docker ./local-dev-publish.sh
