buildspec-router.yml

version: 0.2

# This is a router buildspec that can dynamically run different build processes
# based on environment variables set in the CodeBuild project.
#
# Example usage:
# - Set BUILD_TYPE=cdk and STACK_NAME=SQLAgentStack in the CodeBuild project to build CDK stack
# - Set BUILD_TYPE=lambda, LAMBDA_LANGUAGE=python, and LAMBDA_DIR=lambda/tools/db-interface to build a Lambda function
