🚀 Features

• Full deployment of Dify backend components on Kubernetes
• Support for persistent volumes and configuration via ConfigMaps
• Modular and extensible structure
• Custom Nginx reverse proxy and sandbox environment included
• External integrations: PostgreSQL, Redis, Weaviate

⚙️ Prerequisites

• Kubernetes cluster (v1.20+)
• StorageClass for Persistent Volumes (e.g., Longhorn)

🏗️ Setup Guide

1. Clone the Repository:

git clone https://github.com/Zhoneym/DifyAI-Kubernetes.git
cd DifyAI-Kubernetes

2. Create a Project

kubectl create namespace difyai

3. Create Persistent Volume Claims:

kubectl create -f persistentvolumeclaim/difyai.yaml

4. Create ConfigMaps:

kubectl create -f configmap/difyai-configmap.yaml
kubectl create -f configmap/nginx-configmap-0.yaml -f configmap/nginx-configmap-1.yaml -f configmap/nginx-configmap-2.yaml -f configmap/nginx-configmap-3.yaml -f configmap/nginx-configmap-4.yaml -f configmap/nginx-configmap-5.yaml
kubectl create -f configmap/sandbox-configmap-0.yaml -f configmap/sandbox-configmap-1.yaml
kubectl create -f configmap/ssrf-proxy-configmap-0.yaml -f configmap/ssrf-proxy-configmap-1.yaml

5. Create Core Services:

• PostgreSQL

  kubectl create -f postgresql/statefulset.yaml -f postgresql/service.yaml
  

⚠️ Note: You must initialize the database before proceeding with the deployment.

• Redis

  kubectl create -f redis/statefulset.yaml -f redis/service.yaml
  

• Weaviate

  kubectl create -f weaviate/statefulset.yaml -f weaviate/service.yaml
  

6. Create Dify Components:

• Plugin Daemon

  kubectl create -f plugin-daemon/deployment.yaml -f plugin-daemon/service.yaml
  

• Sandbox

  kubectl create -f sandbox/deployment.yaml -f sandbox/service.yaml
  

• SSRF Proxy

  kubectl create -f ssrf-proxy/deployment.yaml -f ssrf-proxy/service.yaml
  

• API

  kubectl create -f api/statefulset.yaml -f api/service.yaml
  

• Web UI

  kubectl create -f web/deployment.yaml -f web/service.yaml
  

• Worker

  kubectl create -f worker/statefulset.yaml -f worker/service.yaml
  

• Nginx

  kubectl create -f nginx/deployment.yaml -f nginx/service.yaml
  

📌 Notes

• Configuration files can be customized under configmap/
• Ensure that the correct environment variables are set in the Dify ConfigMap
• You may use configmap/genconfig.sh to generate the ConfigMap from a .env file
