# Crossplane Configuration Package Makefile
# ====================================================================================

# USAGE DOCUMENTATION
# ====================================================================================
#
# This is a generic Makefile to be used across repositories building Crossplane
# configuration packages. It provides a comprehensive set of targets for development,
# testing, and deployment.
#
# PROJECT CONFIGURATION
# -------------------
# Create a project.mk file in your repository to configure project-specific settings.
# Required variables:
# - PROJECT_NAME: Name of your Crossplane configuration package
#
# Example project.mk:
#   PROJECT_NAME = custom-config
#   UPTEST_DEFAULT_TIMEOUT = 3600s
#   UPTEST_SKIP_IMPORT = true
#
# PRIMARY TARGETS
# --------------
#
# Development Tools:
# -----------------
# - `yamllint`
#   Runs yamllint recursively on all files in the `api` folder to ensure YAML
#   quality and consistency
#
# - `check-examples`
#   Validates consistency between example configurations and dependencies:
#   - Compares Function package versions in examples/ against crossplane.yaml
#   - Ensures all Function versions in examples match dependency declarations
#   - Helps prevent version mismatches that could cause deployment issues
#   Example errors:
#     - Example using function-foo:v1.2.0 while crossplane.yaml specifies v1.1.0
#     - Missing Function dependencies in crossplane.yaml that are used in examples
#   Usage: Run before committing changes to ensure example validity
#
# Rendering and Validation:
# -----------------
# - `render`
#   Renders the composition output for rapid feedback during template development.
#   Requirements:
#   - Claims must have these annotations:
#       render.crossplane.io/composition-path: apis/pat/composition.yaml
#       render.crossplane.io/function-path: examples/functions.yaml
#   Note: This only populates the cache. Use `render.show` to view output.
#
# - `render.show`
#   Displays the rendered YAML output. Useful for:
#   - Manual validation
#   - Piping to validation tools, e.g.:
#     make render.show | crossplane beta validate crossplane.yaml -
#
# Testing:
# -----------------
# - `render.test`
#   Executes kcl-unit tests on rendered manifests. Tests should be:
#   - Located in the `test` folder
#   - Written as standard kcl-tests
#   This ensures the rendered output meets expected specifications.
#
# - `e2e`
#   Comprehensive end-to-end testing, including:
#   - Cluster creation
#   - Configuration setup
#   - Testing create, import, and delete operations
#
#   Cloud Provider Requirements:
#   For configurations creating cloud provider resources, set:
#   UPTEST_CLOUD_CREDENTIALS - Provider-specific credentials:
#   - AWS:   export UPTEST_CLOUD_CREDENTIALS=$(cat ~/.aws/credentials)
#   - GCP:   export UPTEST_CLOUD_CREDENTIALS=$(cat gcp-sa.json)
#   - Azure: export UPTEST_CLOUD_CREDENTIALS=$(cat azure.json)
#
#   Configuration Options:
#   - UPTEST_SKIP_DELETE (default: false)
#     Skip deletion testing of created resources
#   - UPTEST_SKIP_UPDATE (default: false)
#     Skip testing of claim updates
#   - UPTEST_SKIP_IMPORT (default: false)
#     Skip testing of resource imports
#
#   Example Usage:
#     make e2e UPTEST_SKIP_DELETE=true
#
# LANGUAGE-SPECIFIC OPTIONS
# ------------------------
#
# KCL Support:
# - KCL_COMPOSITION_PATH
#   Path to the KCL file generating composition.yaml
#   Default: apis/kcl/generate.k
#
# NOTE: The platform setting is constrained to linux_amd64 as Configuration package
# images are not architecture-specific. This avoids unnecessary multi-arch image
# generation.

# Initial Setup
# ------------------
# We want submodules to be set up the first time `make` is run.
# We manage the build/ folder and its Makefiles as a submodule.
# The first time `make` is run, the includes of build/*.mk files will
# all fail, and this target will be run. The next time, the default as defined
# by the includes will be run instead.
fallthrough: submodules  ## Initial setup and submodule initialization
	@echo Initial setup complete. Running make again . . .

# Build Targets

# machinery prior to the xpkg machinery sets UP to point to tool cache.
