Documentation

gcp-pubsub

Pub/Sub topics with schemas, push/pull/BigQuery subscriptions, dead-letter queues and retry policies preconfigured. The parts hand-rolled configs always miss are wired in: a DLQ topic plus a retention subscription (without one, dead letters are silently dropped), and the Pub/Sub service-agent IAM grants (publisher on the DLQ, subscriber on each source subscription) without which dead-lettering simply does not fire. Works with Terraform and OpenTofu (>= 1.6), Google provider >= 7.0, < 8.0.

What you get per module call:

  • One topic, optionally schema-enforced (AVRO / protobuf) and CMEK-encrypted
  • Any mix of pull, push (with OIDC auth) and BigQuery subscriptions
  • Dead-letter topic + 7-day retention subscription + service-agent IAM, on by default for every subscription (opt out per subscription)
  • Exponential retry policy (10s–600s) instead of the instant-retry default
  • Publisher/subscriber IAM grants as plain member lists
