Hosting Skill - GCP Cloud Run Deployment

This skill helps deploy and manage the blog on Google Cloud Platform Cloud Run.

Commands

Deploy to GCP Cloud Run

To deploy the blog to GCP:

1. Build and push Docker image to Artifact Registry:

cd packages/blog
gcloud builds submit \
  --tag us-central1-docker.pkg.dev/blog-chris-towles/blog-images/blog:latest \
  --project=blog-chris-towles

2. Deploy to Cloud Run:

gcloud run deploy blog \
  --image us-central1-docker.pkg.dev/blog-chris-towles/blog-images/blog:latest \
  --platform managed \
  --region us-central1 \
  --add-cloudsql-instances blog-chris-towles:us-central1:blog-db \
  --allow-unauthenticated \
  --project=blog-chris-towles

View Logs

View application logs from Cloud Run:

gcloud run logs read blog --region=us-central1 --project=blog-chris-towles

Follow logs in real-time:

gcloud run logs tail blog --region=us-central1 --project=blog-chris-towles

Check Status

Check service status and configuration:

gcloud run services describe blog --region=us-central1 --project=blog-chris-towles

List all Cloud Run services:

gcloud run services list --project=blog-chris-towles

Get service URL:

gcloud run services describe blog --region=us-central1 --project=blog-chris-towles --format='value(status.url)'

Manage Environment Variables

Set environment variables:

gcloud run services update blog \
  --set-env-vars="KEY1=value1,KEY2=value2" \
  --region=us-central1 \
  --project=blog-chris-towles

View current environment variables:

gcloud run services describe blog --region=us-central1 --project=blog-chris-towles --format='value(spec.template.spec.containers[0].env)'

Rollback

List revisions:

gcloud run revisions list --service=blog --region=us-central1 --project=blog-chris-towles

Rollback to a previous revision:

gcloud run services update-traffic blog \
  --to-revisions=REVISION_NAME=100 \
  --region=us-central1 \
  --project=blog-chris-towles

Project Configuration

• Project ID: blog-chris-towles
• Region: us-central1
• Service Name: blog
• Image Registry: us-central1-docker.pkg.dev/blog-chris-towles/blog-images
• Database: Cloud SQL PostgreSQL (blog-db)

Usage Notes

• Cloud Run auto-scales from 0 to configured max instances
• Cold starts occur when scaling from 0
• Secrets should be managed via Secret Manager, not environment variables
• Database connections use Cloud SQL Proxy automatically when configured
