#
# Install External Secrets Operator V2 for E2E testing
# This script deploys the controller and Kubernetes provider using the monolithic Helm chart
#
# Prerequisites:
#   - kubectl and helm installed
#   - Access to a Kubernetes cluster (kind recommended for local testing)
#   - Docker images built and available:
#     * ghcr.io/external-secrets/external-secrets:latest
#     * ghcr.io/external-secrets/provider-kubernetes:latest
#
# For kind clusters, images will be automatically loaded if available locally.
#
# Build images before running (if not already built):
#   make docker.build VERSION=latest
#   # This builds:
#   #   - Controller: ghcr.io/external-secrets/external-secrets:latest
#   #   - Kubernetes Provider: ghcr.io/external-secrets/provider-kubernetes:latest
#   #   - AWS Provider: ghcr.io/external-secrets/provider-aws:latest
