GCP API Gateway Demo
This repository is a companion repo for the article: GCP API Gateway Demo with Terraform, Go and Cloud Run
!!! THIS IS A PROOF OF CONCEPT. NOT INTENDED FOR PRODUCTION USE !!!
Prerequisites
- Go >= 0.15.2
- Terraform >= 0.13.3
- gcloud / Google cloud SDK >= 311.0
- Make >= 3.81

Env
Set env variables for the gcp project id and the region
PROJECT_ID=my-project-id
REGION=europe-west1
Setup gcloud
Authenticate
gcloud auth login
Create a new gcp project (choose a unique PROJECT_ID)
gcloud projects create $PROJECT_ID
Create a service account
SERVICE_ACCOUNT=deployer
gcloud iam service-accounts create $SERVICE_ACCOUNT \
--project $PROJECT_ID
Grant admin role to the service account (clearly more than is actually here, we could narrow it down)
gcloud projects add-iam-policy-binding $PROJECT_ID \
--member=serviceAccount:$SERVICE_ACCOUNT@$PROJECT_ID.iam.gserviceaccount.com \
--role=roles/admin \
--project $PROJECT_ID
Create Service Account keys
gcloud iam service-accounts keys create tf/sa.json \
--iam-account $SERVICE_ACCOUNT@$PROJECT_ID.iam.gserviceaccount.com \
--project $PROJECT_ID
Enable APIS
PROJECT_ID=$PROJECT_ID make gcp-enable-apis
Build/Push containers
Build/Push users service container
PROJECT_ID=$PROJECT_ID make gcr-push-users
Build/Push locations service container
PROJECT_ID=$PROJECT_ID make gcr-push-locations
Terraform setup
Init
make tf-init
Populate tfvars
cp terraform.tfvars.example terraform.tfvars
then modify the variables in terraform.tfvars
Terraform deploy
Plan
make tf-plan
Apply
make tf-apply
Deploy API Gateway
Build config
make build-api-gateway-config
Deploy the gateway
PROJECT_ID=$PROJECT_ID REGION=$REGION make deploy-api-gateway
Get gateway url
PROJECT_ID=$PROJECT_ID REGION=$REGION make get-gateway-url
