Documentation
gcp-composer
Managed Apache Airflow on Cloud Composer 2. Composer runs Airflow on a
Google-managed GKE Autopilot cluster with a managed Cloud SQL metadata database
and a GCS DAG bucket — this module wraps it with small-by-default sizing, pinned
worker autoscaling for predictable cost, and an opt-in private posture. Works
with Terraform and OpenTofu (>= 1.6), Google provider >= 7.0, < 8.0.
Defaults:
environment_size = "ENVIRONMENT_SIZE_SMALL"with the smallest workloads (0.5 vCPU each) and a single pinned worker- Current
composer-2-airflow-2image line (latest patch) - Public environment unless
enable_private_environment = true(private needs a VPC subnetwork with Private Google Access)
Cost & time: Composer is the most expensive module in this catalog and the slowest to stand up — a small environment takes ~25 min to create and bills for the underlying GKE cluster, Cloud SQL and web server for as long as it exists.
Requirements
