# Cloud Run Basics Cloud Run is a fully managed application platform for running your code, function, or container on top of Google's highly scalable infrastructure. It abstracts away infrastructure management, providing three primary resource types: 1. **Services:** Responds to HTTP requests sent to a unique and stable endpoint, using stateless instances that autoscale based on a variety of key metrics, also responds to events and functions. 2. **Jobs:** Executes parallelizable tasks that are executed manually, or on a schedule, and run to completion. 3. **Worker pools:** Handles always-on background workloads such as pull-based workloads, for example, Kafka consumers, Pub/Sub pull queues, or RabbitMQ consumers. ## Prerequisites Enable the Cloud Run Admin API and Cloud Build APIs: ```bash gcloud services enable run.googleapis.com cloudbuild.googleapis.com ``` ### Required roles - Cloud Run Admin (`roles/run.admin`) on the project - Cloud Run Source Developer (`roles/run.sourceDeveloper`) on the project - Service Account User (`roles/iam.serviceAccountUser`) on the service identity - Logs Viewer (`roles/logging.viewer`) on the project ## Deploy a Cloud Run service > **CRITICAL RULE:** Any deployed code MUST listen on 0.0.0.0 (not 127.0.0.1) > and use the injected $PORT environment variable (defaults to 8080), or it will > crash on boot. ### Deploy a container image ```bash gcloud run deploy SERVICE_NAME \ --image IMAGE_URL \ --region
