API Key Authentication with Google Cloud API Gateway and Cloud Run

Create API Gateway

Now that we have the API Gateway API and an API Gateway Config, we can create the API Gateway itself. Back to good ol’ gcloud:

gcloud api-gateway gateways create {{GATEWAY_ID}} \
  --api={{API_ID}} --api-config={{CONFIG_ID}} \
  --location={{GCP_REGION}} --project={{PROJECT_ID}}

Where:

• {{GATEWAY_ID}}: Name of the API Gateway we want to create. I like to just use the same name as the API_ID with “-gateway” appended to the end (e.g. demo-api-gateway).
• {{API_ID}}: The ID of the API Gateway API created in the previous section. (e.g. demo-api).
• {{CONFIG_ID}}: The ID of the API Gateway API Config we created previously (e.g. demo-api-config).
• {{GCP_REGION}}: The region where our Cloud Run service was deployed (e.g. us-central1).
• {{PROJECT_ID}}: Name of the Google Cloud project you’re using for the tutorial (e.g. api-gateway-key-auth-demo)
