Verification
Live-testedReally deployed to a cloud sandbox, verified against its outputs and assertions, then destroyed - with the teardown confirmed.

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
Requirements
| Requirement | Version |
|---|---|
| Terraform / OpenTofu | >= 1.6 |

Related modules
gcp-cloud-scheduler
A Cloud Scheduler cron job that calls an HTTP(S) endpoint on a schedule, with a bounded attempt deadline, capped exponential-backoff retries, and per-invocation OIDC/OAuth service-account auth.
gcp-cloud-tasks
A Cloud Tasks queue with capped dispatch rate and concurrency, a bounded exponential-backoff retry policy, and full Stackdriver logging so failed dispatches are observable rather than silent.
gcp-eventarc
An Eventarc Pub/Sub trigger wired into a self-contained pipeline - a Cloud Run target, a dedicated delivery service account, and the run.invoker and eventReceiver grants Eventarc silently requires.
aws-mq
deployment_mode defaults to SINGLE_INSTANCE, and Amazon MQ reboots the instance to patch it - so a single broker has planned downtime on AWS's schedule. Active/standby across two AZs, both log streams on, and passwords in a separate variable from users, because a sensitive value cannot be a for_each argument at all.
aws-kinesis-firehose
Without error_output_prefix, records Firehose could not process are written into the same prefix as the ones it could, wrapped in an error envelope that whatever reads the prefix treats as data. Nothing reports it.
huawei-kafka-streaming
A DMS Kafka instance with enable_auto_topic off, because a producer that misspells a topic otherwise creates one: the messages go somewhere real, nothing errors, and nobody consumes them. TLS and SASL are both on, which is what makes the user mean anything; the disk is encrypted at creation; and what happens when the disk fills is a decision you take.
