Host Your Payload v3 App on GCP - Complete Guide

Payload 3.0, an open-source CMS powered by Next.js, is a great choice for cloud deployment, and Google Cloud Platform (GCP) offers a flexible environment to host it. Whether you use Cloud Run or Compute Engine, this guide provides a clear path to download and deploy Payload 3.0 on GCP, ensuring accuracy and ease.

GCP brings several advantages for Payload 3.0:

• Cost-Effective: Offers a generous free tier and pay-as-you-go pricing.

• Scalability: Cloud Run auto-scales based on demand.

• Storage Options: Integrate with Google Cloud Storage for files.

• Global Reach: Deploy across multiple regions for low latency.

Get these ready before you start:

• GCP Account: Sign up at cloud.google.com if needed.

• Node.js: Install version 18+ locally.

• Git: Verify with git --version.

• Database: Set up Cloud SQL (PostgreSQL) or MongoDB Atlas with a connection string.

• GCP SDK: Install with gcloud init to configure your project.

Follow these steps to set up Payload 3.0 on GCP:

Step 1: Clone the Repository

• Run git clone https://github.com/payloadcms/payload-3.0-demo.git on your local machine.
• Change to the folder with cd payload-3.0-demo

Step 2: Install Dependencies

• Execute pnpm i (or npm install) to install packages.
• Pnpm is preferred for speed and efficiency.

Step 3: Configure Environment Variables

Copy .env.local.example to .env.local with cp .env.local.example .env.local

Edit with:

• PAYLOAD_SECRET: A random secure string.
• DATABASE_URI: Your Cloud SQL or MongoDB Atlas connection

• NEXT_PUBLIC_SERVER_URL: Your GCP domain (e.g., https://your-project-id.ew.r.appspot.com).

Save the file.

Step 4: Build the Application

• Run pnpm build to create a production build.
• This prepares Payload for deployment on GCP.

Step 5: Deploy to GCP

Option 1: Cloud Run

• Create a container image with a Dockerfile (example in Payload docs).
• Build and push the image to Google Container Registry with gcloud builds submit --tag gcr.io/[PROJECT-ID]/payload
• Deploy with gcloud run deploy --image gcr.io/[PROJECT-ID]/payload --platform managed
• Set environment variables during deployment

Option 2: Compute Engine

• Launch a VM instance (e.g., e2-micro with Ubuntu).
• SSH in, install Node.js, and upload your project files.
• Run pnpm start to launch the app.
• Configure a firewall rule to allow port 3000.

Step 6: Set Up File Storage

• Create a Google Cloud Storage bucket in the GCP Console.
• Configure Payload to use the storage adapter (see Payload docs for setup).
• Ensure proper IAM permissions for bucket access.

Step 7: Access the Site

• Use the Cloud Run URL or Compute Engine IP with port 3000 (e.g., http://your-ip:3000).
• Log in with the default admin user from the config.

Resolve these potential issues:

• Deployment Fails: Check logs with gcloud run logs read or VM logs.

• Database Errors: Ensure DATABASE_URI matches your Cloud SQL instance and network settings.

• Storage Access: Verify bucket permissions and adapter configuration.

• Port Conflicts: Adjust firewall rules or change the app port.

Improve your setup with these ideas:

• Use a Load Balancer: Add a GCP Load Balancer for traffic distribution.

• Monitor Usage: Set up Cloud Monitoring to track performance.

• Backup Data: Regularly back up your Cloud SQL database.

• Optimize Costs: Use the free tier and scale instances as needed.

Enhance your GCP deployment:

• Custom Domains: Map a domain with Cloud DNS.

• Auto-Scaling: Configure Cloud Run to adjust instances based on traffic.

• SSL: Enable HTTPS with Google Managed Certificates.

Deploying Payload 3.0 on GCP with Cloud Run or Compute Engine offers a scalable and cost-effective solution. By cloning the repo, building your app, and setting up the right services, you can launch a robust CMS. With storage and monitoring in place, your Payload 3.0 site will thrive on GCP.
