install-odh.sh

#!/usr/bin/env bash
# Install OpenDataHub (ODH) operator and apply DataScienceCluster (KServe).
# MaaS is deployed separately via deploy.sh --deployment-mode kustomize.
#
# Prerequisites: cert-manager and LWS operators (run install-cert-manager-and-lws.sh first).
#
# Environment variables:
#   OPERATOR_CATALOG - Custom catalog image (optional). When unset, uses community-operators.
#                      Set to e.g. quay.io/opendatahub/opendatahub-operator-catalog:latest for custom builds.
#   OPERATOR_CHANNEL   - Subscription channel (default: fast-3)
#   OPERATOR_STARTING_CSV - Pin Subscription startingCSV (default: opendatahub-operator.v3.4.0-ea.1). Set to "-" to omit.
#   OPERATOR_INSTALL_PLAN_APPROVAL - Manual (default) or Automatic; use "-" to omit.
#     Manual: blocks auto-upgrades; this script auto-approves only the first InstallPlan so install does not stall.
#   OPERATOR_IMAGE   - Custom operator image to patch into CSV (optional)
#
# Usage: ./install-odh.sh
