How to Deploy to Cloud Run: Simple Steps for GCP Deployment

To deploy to Cloud Run, first build a container image of your app and push it to Google Container Registry or Artifact Registry. Then run gcloud run deploy with your service name and image URL to launch your app as a serverless container.

Syntax

The basic command to deploy an app to Cloud Run is:

gcloud run deploy SERVICE_NAME --image IMAGE_URL --platform managed --region REGION

Here’s what each part means:

• SERVICE_NAME: The name you want for your Cloud Run service.
• IMAGE_URL: The full path to your container image in Google Container Registry or Artifact Registry.
• --platform managed: Specifies you want to use fully managed Cloud Run.
• --region: The Google Cloud region where you want to deploy.

bash

gcloud run deploy SERVICE_NAME --image IMAGE_URL --platform managed --region REGION

Example

This example shows how to deploy a simple container image named gcr.io/my-project/my-app as a Cloud Run service called my-service in the us-central1 region.

bash

gcloud run deploy my-service --image gcr.io/my-project/my-app --platform managed --region us-central1

Output

Deploying container to Cloud Run service [my-service] in project [my-project] region [us-central1]

✓ Deploying new service... Done.
  ✓ Creating Revision...
  ✓ Routing traffic...

Service [my-service] revision [my-service-00001-abc] has been deployed and is serving 100 percent of traffic.

Service URL: https://my-service-abcdefg-uc.a.run.app

Common Pitfalls

Some common mistakes when deploying to Cloud Run include:

• Not building and pushing the container image before deploying. You must have your image in a registry accessible by Cloud Run.
• Forgetting to specify the --platform managed flag, which is required for fully managed Cloud Run.
• Using the wrong region or a region where Cloud Run is not available.
• Not setting correct permissions for the Cloud Run service account to access the container image.

Always verify your image URL and region before deploying.

bash

Wrong:
gcloud run deploy my-service --image my-app-image

Right:
gcloud run deploy my-service --image gcr.io/my-project/my-app --platform managed --region us-central1

Quick Reference

Remember these key points when deploying to Cloud Run:

• Build your container image locally or with Cloud Build.
• Push the image to Google Container Registry or Artifact Registry.
• Use gcloud run deploy with --platform managed and specify your region.
• Check your service URL after deployment to access your app.

Key Takeaways

Build and push your container image before deploying to Cloud Run.

Use the command 'gcloud run deploy SERVICE_NAME --image IMAGE_URL --platform managed --region REGION' to deploy.

Always specify the platform as managed and choose a supported region.

Verify permissions so Cloud Run can access your container image.

Check the service URL after deployment to access your running app.
