Terraform for Dify on Google Cloud

[!NOTE]

• Dify v1.0.0 (and later) is supported now! Try it and give us feedbacks!!
• If you fail to install any plugin, try several times and succeed in many cases.

Overview

This repository allows you to automatically set up Google Cloud resources using Terraform and deploy Dify in a highly available configuration.

Features

• Serverless hosting
• Auto-scaling
• Data persistence

Prerequisites

• Google Cloud account
• Terraform installed
• gcloud CLI installed

Configuration

• Set environment-specific values in the terraform/environments/dev/terraform.tfvars file.

[!WARNING] Security Alert: Handling terraform.tfvars The terraform/environments/dev/terraform.tfvars file in this repository is a template only. Populate it locally with your actual configuration (project ID, secrets, secure password).

Do NOT commit terraform.tfvars containing sensitive data to Git. This poses a significant security risk.

Add *.tfvars to your .gitignore file immediately to prevent accidental commits. For secure secret management, use environment variables (TF_VAR_...) or tools like Google Secret Manager.

• Create a GCS bucket to manage Terraform state in advance, and replace "your-tfstate-bucket" in the terraform/environments/dev/provider.tf file with the name of the created bucket.

Getting Started

1. Clone the repository:

   git clone https://github.com/DeNA/dify-google-cloud-terraform.git
   

2. Initialize Terraform:

   cd terraform/environments/dev
   terraform init
   

3. Make Artifact Registry repository:

   terraform apply -target=module.registry
   

4. Build & push container images:

   cd ../../..
   sh ./docker/cloudbuild.sh <your-project-id> <your-region>
   

   You can also specify a version of the dify-api image.

   sh ./docker/cloudbuild.sh <your-project-id> <your-region> <dify-api-version>
   

   If no version is specified, the latest version is used by default.

5. Terraform plan:

   cd terraform/environments/dev
   terraform plan
   

6. Terraform apply:

   terraform apply
   

Cleanup

terraform destroy

Note: Cloud Storage, Cloud SQL, VPC, and VPC Peering cannot be deleted with the terraform destroy command. These are critical resources for data persistence. Access the console and carefully delete them. After that, use the terraform destroy command to ensure all resources have been deleted.
