GCP TesseraCT CI Environment

Overview

This config uses the gcp/cloudrun module to define a CI environment to run TesseraCT on Cloud Run, backed by Tessera.

At a high level, this environment consists of:

  • One Spanner instance with two databases:
    • one for Tessera
    • one for antispam
  • A GCS Bucket
  • Secret Manager
  • Cloud Run

Automatic Deployment

This GCP TesseraCT conformance CI environment is designed to be deployed by the Cloud Build (OpenTofu module, Terragrunt configuration).

Manual Deployment

First authenticate via gcloud as a principal with sufficient ACLs for the project:

gcloud auth application-default login

Set the required environment variables:

export GOOGLE_PROJECT={VALUE}
export GOOGLE_REGION={VALUE} # e.g: us-central1
unset TESSERA_BASE_NAME

You need an Artifact Registry repository to store container images; adapt the configs and commands below to use your registry of choice. The rest of these instructions assume that the repository is hosted on GCP, and called ${GOOGLE_REGION}-docker.pkg.dev/${GOOGLE_PROJECT}/docker-ci. For reference, here's a OpenTofu module you can use to set up such a registry.

Build and push the Docker image to Artifact Registry repository:

gcloud auth configure-docker ${GOOGLE_REGION}-docker.pkg.dev
docker build -f ./cmd/tesseract/gcp/Dockerfile -t tesseract-gcp:latest .
docker build -f ./cmd/tesseract/gcp/ci/Dockerfile -t conformance-gcp:latest .
docker tag conformance-gcp:latest ${GOOGLE_REGION}-docker.pkg.dev/${GOOGLE_PROJECT}/docker-ci/conformance-gcp:latest
docker push ${GOOGLE_REGION}-docker.pkg.dev/${GOOGLE_PROJECT}/docker-ci/conformance-gcp

Deploy the Terraform config with OpenTofu:

  1. cd to /deployment/live/gcp/static-ct-ci/logs/ci/.
  2. Run terragrunt apply.
