Google Cloud Run | Serverless - Swiftorial Lessons

Overview

Google Cloud Run is a fully managed compute platform that automatically scales your stateless containers. It allows developers to run containerized applications without managing the underlying infrastructure. Cloud Run is serverless, meaning that you pay only for the resources you use, and it can scale from zero to N instances based on demand.

Key Points

Serverless architecture reduces operational overhead.
Supports any programming language that can run in a container.
Automatic scaling based on incoming traffic.
Integration with Google Cloud services such as Cloud Pub/Sub, Firestore, etc.
Provides built-in security via HTTPS and IAM roles.

Setup

To deploy a service to Google Cloud Run, follow these steps:

Install the Google Cloud SDK and initialize it with your account.
Build your container image using Docker:


docker build -t gcr.io/[PROJECT-ID]/[IMAGE_NAME] .

Push the image to Google Container Registry:


docker push gcr.io/[PROJECT-ID]/[IMAGE_NAME]

Deploy to Cloud Run:


gcloud run deploy --image gcr.io/[PROJECT-ID]/[IMAGE_NAME] --platform managed

Follow the prompts to select the region and service name.

Best Practices

When using Google Cloud Run, consider the following best practices:

Optimize your container images for faster start-up times.
Use environment variables for configuration.
Monitor your services using Google Cloud Monitoring.
Implement logging for better troubleshooting.
Set up IAM policies to control access to your services.

FAQ

What is the difference between Google Cloud Run and Google Kubernetes Engine?

Google Cloud Run is a serverless platform that abstracts away infrastructure management, allowing you to focus on your code. Google Kubernetes Engine (GKE) is a managed Kubernetes service that provides more control over the infrastructure and orchestration of containers.

Can Cloud Run run stateful applications?

No, Google Cloud Run is designed for stateless applications. If you need stateful services, consider using Cloud SQL or Firestore alongside Cloud Run.

What programming languages can I use with Cloud Run?

You can use any programming language that can run in a container, including but not limited to Python, Go, Node.js, Java, and Ruby.
