# Containerfile for building OLMv0 Bundle image
#
# This Containerfile creates a bundle image containing operator manifests (CSV, CRDs)
# and metadata for deployment via OLMv0 on legacy Kubernetes/OpenShift clusters.
#
# Build command:
#   podman build -f Containerfile.bundle -t ghcr.io/stacklok/toolhive-operator-metadata/bundle:v0.6.11 .
#
# Validation command (before build):
#   /opt/operator-sdk/bin/operator-sdk --plugins go.kubebuilder.io/v4 bundle validate ./bundle --select-optional suite=operatorframework
#
# Validation command (after build):
#   /opt/operator-sdk/bin/operator-sdk --plugins go.kubebuilder.io/v4 bundle validate ghcr.io/stacklok/toolhive-operator-metadata/bundle:v0.6.11

# Use scratch base image for minimal size and security
# Bundle images are data-only (no executables needed)
FROM scratch

# Add bundle directories to standard OLM paths
# /manifests/ contains CSV and CRD YAML files
# /metadata/ contains annotations.yaml with OLM metadata
ADD bundle/manifests /manifests/
ADD bundle/metadata /metadata/

# Required OLM labels for bundle discovery
# These MUST match the annotations in /metadata/annotations.yaml
