GTFS Infrastructure

Quick Start

terraform

Relevant paths include:

• domain/gtfs-infrastructure.tfvars: manage infrastructure configuration (definitions)
• terraform/*: manage infrastructure implementation

To test changes:

make -C pipelines/iac ci

To apply changes:

make -C pipelines/iac cd

Re-init terraform (required when, e.g., new or renamed module, new provider, etc):

rm -r terraform/.terraform
make -C pipelines/iac ci

One-Time Setup

These steps must be performed once at creation time of the project

terraform

1. Create a bucket for terraform state

gcloud storage buckets create gs://gtfs-infrastructure-tfstate

github actions

1. Create a service account

gcloud iam service-accounts create github-actions \
  --display-name="GitHub Actions Runner"

2. Grant the account privileges to manage the project

gcloud projects add-iam-policy-binding web-based-gtfs-validator \
  --member=serviceAccount:github-actions@web-based-gtfs-validator.iam.gserviceaccount.com \
  --role=roles/owner

3. Provision a key for the service account

gcloud iam service-accounts keys create .git/github-actions-sa.json \
  --iam-account=github-actions@web-based-gtfs-validator.iam.gserviceaccount.com

4. Upload the key to a GitHub Actions secret

gh -R MobilityData/gtfs-infrastructure secret set GCP_SA_KEY < .git/github-actions-sa.json
