-# KubeBlocks Databases Helm Chart
-
-This Helm chart deploys and manages multiple database clusters (PostgreSQL, Redis, Elasticsearch, Qdrant) using [KubeBlocks](https://kubeblocks.io/).
-
-## Prerequisites
-
-*   Kubernetes cluster (version compatible with KubeBlocks)
-*   [Helm](https://helm.sh/docs/intro/install/) (version 3+) installed.
-*   [KubeBlocks](https://kubeblocks.io/docs/preview/user_docs/installation) installed in your Kubernetes cluster.
-*   `kubectl` configured to interact with your cluster.
-
-```bash
-kubectl create namespace kb-system
-kbcli kubeblocks install --version=1.0.0-beta.47 --namespace kb-system
-```
-
-
-## Installation
-
-```bash
-helm repo remove kubeblocks
-helm repo add kubeblocks https://apecloud.github.io/helm-charts
-helm repo update
-
-helm upgrade --install kb-addon-elasticsearch kubeblocks/elasticsearch --namespace kb-system --version 1.0.0-alpha.0
-helm upgrade --install kb-addon-qdrant kubeblocks/qdrant --namespace kb-system --version 1.0.0-alpha.0
-helm upgrade --install kb-addon-postgresql kubeblocks/postgresql --namespace kb-system --version 1.0.0-alpha.0
-helm upgrade --install kb-addon-redis kubeblocks/redis --namespace kb-system --version 1.0.0-alpha.0
-```
-
-```bash
-kubectl create namespace demo
-kubectl create secret generic postgresql-secret \
-  --namespace=demo \
-  --from-literal=username=postgres \
-  --from-literal=password=postgres
-kubectl create secret generic redis-secret \
-  --namespace=demo \
-  --from-literal=username=default \
-  --from-literal=password=password
-helm install kb-databases ./kubeblocks-databases -n demo --create-namespace \
--set redis.customSecretName=redis-secret,redis.customSecretNamespace=demo,postgresql.customSecretName=postgresql-secret,postgresql.customSecretNamespace=demo
-```
-
-generate template:
-```bash
-helm template kb-databases ./kubeblocks-databases -n demo --create-namespace \
--set redis.customSecretName=redis-secret,redis.customSecretNamespace=demo,postgresql.customSecretName=postgresql-secret,postgresql.customSecretNamespace=demo \
-> rendered.yaml
-```
-
-## Verification
-
-After installation, you can check the status of the deployed KubeBlocks clusters:
-
-```bash
-kubectl get clusters -n demo
-kubectl get pods -n demo
-```
-
-
-You should see the `Cluster` resources for the enabled databases and their corresponding pods. The `NOTES.txt` output from Helm will also provide some of this information.
-
-```bash
-kubectl get clusters -n demo
-NAME               CLUSTER-DEFINITION   TERMINATION-POLICY   STATUS     AGE
-es-cluster                              Delete               Running    121m
-pg-cluster         postgresql           Delete               Creating   121m
-qdrant-cluster     qdrant               Delete               Running    121m
-redis-standalone   redis                Delete               Running    121m
-
-kubectl get pods -n demo
-NAME                       READY   STATUS    RESTARTS   AGE
-es-cluster-mdit-0          3/3     Running   0          110m
-pg-cluster-postgresql-0    5/5     Running   0          121m
-qdrant-cluster-qdrant-0    2/2     Running   0          117m
-redis-standalone-redis-0   3/3     Running   0          121m
-```
-
-## Connect
-
-port-forward:
-```bash
-echo "Starting Elasticsearch port-forward..."
-kubectl port-forward -n demo service/es-cluster-mdit-http 9200:9200 &
-ES_PID=$!
-echo "Elasticsearch port-forward process ID: $ES_PID"
-echo "Starting Qdrant port-forward..."
-kubectl port-forward -n demo service/qdrant-cluster-qdrant-qdrant 6333:6333 &
-QDRANT_PID=$!
-echo "Qdrant port-forward process ID: $QDRANT_PID"
-echo "Starting PostgreSQL port-forward..."
-kubectl port-forward -n demo service/pg-cluster-postgresql-postgresql 5432:5432 &
-PG_PID=$!
-echo "PostgreSQL port-forward process ID: $PG_PID"
-echo "Starting Redis port-forward..."
-kubectl port-forward -n demo service/redis-standalone-redis-redis 6379:6379 &
-REDIS_PID=$!
-echo "Redis port-forward process ID: $REDIS_PID"
-echo "All port-forwards have been started"
-echo "Press Ctrl+C to stop all port-forwards"
-# Capture Ctrl+C signal and clean up all processes
-trap "kill $ES_PID $QDRANT_PID $PG_PID $REDIS_PID; echo 'All port-forwards stopped'; exit" INT
-# Wait for any child process to finish
-wait
-```
-
-## Uninstallation
-
-To uninstall the deployed database clusters:
-
-```bash
-helm uninstall kb-databases -n demo
-```
-This will remove all Kubernetes resources associated with this Helm release, including the KubeBlocks `Cluster` objects. Depending on the `terminationPolicy` and KubeBlocks behavior, PVCs might also be deleted.
-
-
-## Configuration
-
-The primary way to configure the deployments is through the `values.yaml` file.
-
-### Global Settings
-
-These settings apply to all database clusters deployed by this chart:
-
-```yaml
-global:
-  namespace: "demo"
-  terminationPolicy: "Delete" # Options: DoNotTerminate, Delete, WipeOut
-```
-
-### Per-Database Settings
-
-Each database (PostgreSQL, Redis, Elasticsearch, Qdrant) has its own configuration block. Here's an example for PostgreSQL:
-
-```yaml
-postgresql:
-  enabled: true              # Set to true to deploy this database, false to skip
-  name: "pg-cluster"         # Name of the KubeBlocks Cluster resource
-  serviceVersion: "14.7.2"   # Database engine version
-  disableExporter: false     # true to disable metrics exporter, false to enable
-  replicas: 2                # Number of replicas for the main component
-  resources:                 # CPU and Memory requests/limits
-    limits:
-      cpu: "0.5"
-      memory: "0.5Gi"
-    requests:
-      cpu: "0.5"
-      memory: "0.5Gi"
-  storage: "20Gi"            # Storage size for the data volume (e.g., PVC)
-```
-
-Refer to `values.yaml` for the full set of configurable options for each database.
-
-**Key configurable parameters for each database:**
-
-*   `enabled`: (boolean) Deploy this database cluster.
-*   `name`: (string) Name for the KubeBlocks `Cluster` resource.
-*   `serviceVersion`: (string) Specific version of the database engine.
-*   `disableExporter`: (boolean) Enable/disable the metrics exporter. (Note: For Elasticsearch, this might be handled differently by its `componentDef`).
-*   `replicas`: (integer) Number of replicas for the primary database component.
-*   `resources`: (object) Standard Kubernetes resource requests and limits.
-*   `storage`: (string) Storage capacity for persistent volumes (e.g., "10Gi", "100Gi").
-*   `topology`: (string, for Redis) e.g., "standalone", "replication".
-*   `componentDef`: (string, for Elasticsearch) e.g., "elasticsearch-8".

+# LightRAG Helm Chart
+
+This is the Helm chart for LightRAG, used to deploy LightRAG services on a Kubernetes cluster.
+
+There are two recommended deployment methods for LightRAG:
+1. **Lightweight Deployment**: Using built-in lightweight storage, suitable for testing and small-scale usage
+2. **Full Deployment**: Using external databases (such as PostgreSQL and Neo4J), suitable for production environments and large-scale usage
+
+## Prerequisites
+
+Make sure the following tools are installed and configured:
+
+* **Kubernetes cluster**
+  * A running Kubernetes cluster is required.
+  * For local development or demos you can use [Minikube](https://minikube.sigs.k8s.io/docs/start/) (needs ≥ 2 CPUs, ≥ 4 GB RAM, and Docker/VM-driver support).
+  * Any standard cloud or on-premises Kubernetes cluster (EKS, GKE, AKS, etc.) also works.
+
+* **kubectl**
+  * The Kubernetes command-line interface.
+  * Follow the official guide: [Install and Set Up kubectl](https://kubernetes.io/docs/tasks/tools/#kubectl).
+
+* **Helm** (v3.x+)
+  * Kubernetes package manager used by the scripts below.
+  * Install it via the official instructions: [Installing Helm](https://helm.sh/docs/intro/install/).
+
+
+## Lightweight Deployment (No External Databases Required)
+
+Uses built-in lightweight storage components with no need to configure external databases:
+
+```bash
+helm upgrade --install lightrag ./lightrag \
+  --namespace rag \
+  --set-string env.LIGHTRAG_KV_STORAGE=JsonKVStorage \
+  --set-string env.LIGHTRAG_VECTOR_STORAGE=NanoVectorDBStorage \
+  --set-string env.LIGHTRAG_GRAPH_STORAGE=NetworkXStorage \
+  --set-string env.LIGHTRAG_DOC_STATUS_STORAGE=JsonDocStatusStorage \
+  --set-string env.LLM_BINDING=openai \
+  --set-string env.LLM_MODEL=gpt-4o-mini \
+  --set-string env.LLM_BINDING_HOST=$OPENAI_API_BASE \
+  --set-string env.LLM_BINDING_API_KEY=$OPENAI_API_KEY \
+  --set-string env.EMBEDDING_BINDING=openai \
+  --set-string env.EMBEDDING_MODEL=text-embedding-ada-002 \
+  --set-string env.EMBEDDING_DIM=1536 \
+  --set-string env.EMBEDDING_BINDING_API_KEY=$OPENAI_API_KEY
+```
+
+You can refer to: [install_lightrag_dev.sh](install_lightrag_dev.sh)
+
+You can use it directly like this:
+```bash
+export OPENAI_API_BASE=<YOUR_OPENAI_API_BASE>
+export OPENAI_API_KEY=<YOUR_OPENAI_API_KEY>
+bash ./install_lightrag_dev.sh
+```
+Then you can Access the application
+```bash
+  1. Run this port-forward command in your terminal:
+    kubectl --namespace rag port-forward svc/lightrag-dev 9621:9621
+
+  2. While the command is running, open your browser and navigate to:
+     http://localhost:9621
+```
+
+## Full Deployment (Using External Databases)
+
+### 1. Install Databases
+> You can skip this step if you've already prepared databases. Detailed information can be found in: [README.md](databases%2FREADME.md).
+
+We recommend KubeBlocks for database deployment. KubeBlocks is a cloud-native database operator that makes it easy to run any database on Kubernetes at production scale.
+FastGPT also use KubeBlocks for their database infrastructure.
+
+First, install KubeBlocks and KubeBlocks-Addons (skip if already installed):
+```bash
+bash ./databases/01-prepare.sh
+```
+
+Then install the required databases. By default, this will install PostgreSQL and Neo4J, but you can modify [00-config.sh](databases%2F00-config.sh) to select different databases based on your needs. KubeBlocks supports various databases including MongoDB, Qdrant, Redis, and more.
+```bash
+bash ./databases/02-install-database.sh
+```
+
+When the script completes, confirm that the clusters are up. It may take a few minutes for all the clusters to become ready,
+   especially if this is the first time running the script as Kubernetes needs to pull container images from registries.
+   You can monitor the progress using the following commands:
+```bash
+kubectl get clusters -n rag
+NAME            CLUSTER-DEFINITION   TERMINATION-POLICY   STATUS     AGE
+neo4j-cluster                        Delete               Running    39s
+pg-cluster      postgresql           Delete               Creating   42s
+```
+You can see all the Database `Pods` created by KubeBlocks.
+   Initially, you might see pods in `ContainerCreating` or `Pending` status - this is normal while images are being pulled and containers are starting up.
+   Wait until all pods show `Running` status:
+```bash
+kubectl get po -n rag
+NAME                      READY   STATUS    RESTARTS   AGE
+neo4j-cluster-neo4j-0     1/1     Running   0          58s
+pg-cluster-postgresql-0   4/4     Running   0          59s
+pg-cluster-postgresql-1   4/4     Running   0          59s
+```
+
+### 2. Install LightRAG
+
+LightRAG and its databases are deployed within the same Kubernetes cluster, making configuration straightforward.
+When using KubeBlocks to provide PostgreSQL and Neo4J database services, the `install_lightrag.sh` script can automatically retrieve all database connection information (host, port, user, password), eliminating the need to manually set database credentials.
+
+You only need to run [install_lightrag.sh](install_lightrag.sh) like this:
+```bash
+export OPENAI_API_BASE=<YOUR_OPENAI_API_BASE>
+export OPENAI_API_KEY=<YOUR_OPENAI_API_KEY>
+bash ./install_lightrag.sh
+```
+
+The above commands automatically extract the database passwords from Kubernetes secrets, eliminating the need to manually set these credentials.
+
+After deployment, you can access the application:
+```bash
+  1. Run this port-forward command in your terminal:
+    kubectl --namespace rag port-forward svc/lightrag 9621:9621
+
+  2. While the command is running, open your browser and navigate to:
+     http://localhost:9621
+```
+
+## Configuration
+
+### Modifying Resource Configuration
+
+You can configure LightRAG's resource usage by modifying the `values.yaml` file:
+
+```yaml
+replicaCount: 1  # Number of replicas, can be increased as needed
+
+resources:
+  limits:
+    cpu: 1000m    # CPU limit, can be adjusted as needed
+    memory: 2Gi   # Memory limit, can be adjusted as needed
+  requests:
+    cpu: 500m     # CPU request, can be adjusted as needed
+    memory: 1Gi   # Memory request, can be adjusted as needed
+```
+
+### Modifying Persistent Storage
+
+```yaml
+persistence:
+  enabled: true
+  ragStorage:
+    size: 10Gi    # RAG storage size, can be adjusted as needed
+  inputs:
+    size: 5Gi     # Input data storage size, can be adjusted as needed
+```
+
+### Configuring Environment Variables
+
+The `env` section in the `values.yaml` file contains all environment configurations for LightRAG, similar to a `.env` file. When using helm upgrade or helm install commands, you can override these with the --set flag.
+
+```yaml
+env:
+  HOST: 0.0.0.0
+  PORT: 9621
+  WEBUI_TITLE: Graph RAG Engine
+  WEBUI_DESCRIPTION: Simple and Fast Graph Based RAG System
+
+  # LLM Configuration
+  LLM_BINDING: openai            # LLM service provider
+  LLM_MODEL: gpt-4o-mini         # LLM model
+  LLM_BINDING_HOST:              # API base URL (optional)
+  LLM_BINDING_API_KEY:           # API key
+
+  # Embedding Configuration
+  EMBEDDING_BINDING: openai                 # Embedding service provider
+  EMBEDDING_MODEL: text-embedding-ada-002   # Embedding model
+  EMBEDDING_DIM: 1536                       # Embedding dimension
+  EMBEDDING_BINDING_API_KEY:                # API key
+
+  # Storage Configuration
+  LIGHTRAG_KV_STORAGE: PGKVStorage              # Key-value storage type
+  LIGHTRAG_VECTOR_STORAGE: PGVectorStorage      # Vector storage type
+  LIGHTRAG_GRAPH_STORAGE: Neo4JStorage          # Graph storage type
+  LIGHTRAG_DOC_STATUS_STORAGE: PGDocStatusStorage  # Document status storage type
+```
+
+## Notes
+
+- Ensure all necessary environment variables (API keys and database passwords) are set before deployment
+- For security reasons, it's recommended to pass sensitive information using environment variables rather than writing them directly in scripts or values files
+- Lightweight deployment is suitable for testing and small-scale usage, but data persistence and performance may be limited
+- Full deployment (PostgreSQL + Neo4J) is recommended for production environments and large-scale usage
+- For more customized configurations, please refer to the official LightRAG documentation

+# Using KubeBlocks to Deploy and Manage Databases
+
+Learn how to quickly deploy and manage various databases in a Kubernetes (K8s) environment through KubeBlocks.
+
+## Introduction to KubeBlocks
+
+KubeBlocks is a production-ready, open-source toolkit that runs any database--SQL, NoSQL, vector, or document--on Kubernetes.
+It scales smoothly from quick dev tests to full production clusters, making it a solid choice for RAG workloads like FastGPT that need several data stores working together.
+
+## Prerequisites
+
+Make sure the following tools are installed and configured:
+
+* **Kubernetes cluster**
+  * A running Kubernetes cluster is required.
+  * For local development or demos you can use [Minikube](https://minikube.sigs.k8s.io/docs/start/) (needs ≥ 2 CPUs, ≥ 4 GB RAM, and Docker/VM-driver support).
+  * Any standard cloud or on-premises Kubernetes cluster (EKS, GKE, AKS, etc.) also works.
+
+* **kubectl**
+  * The Kubernetes command-line interface.
+  * Follow the official guide: [Install and Set Up kubectl](https://kubernetes.io/docs/tasks/tools/#kubectl).
+
+* **Helm** (v3.x+)
+  * Kubernetes package manager used by the scripts below.
+  * Install it via the official instructions: [Installing Helm](https://helm.sh/docs/intro/install/).
+
+## Installing
+
+1. **Configure the databases you want**
+    Edit `00-config.sh` file. Based on your requirements, set the variable to `true` for the databases you want to install.
+    For example, to install PostgreSQL and Neo4j:
+
+   ```bash
+   ENABLE_POSTGRESQL=true
+   ENABLE_REDIS=false
+   ENABLE_ELASTICSEARCH=false
+   ENABLE_QDRANT=false
+   ENABLE_MONGODB=false
+   ENABLE_NEO4J=true
+   ```
+
+2. **Prepare the environment and install KubeBlocks add-ons**
+
+   ```bash
+   bash ./01-prepare.sh
+   ```
+
+   *What the script does*
+   `01-prepare.sh` performs basic pre-checks (Helm, kubectl, cluster reachability), adds the KubeBlocks Helm repo, and installs any core CRDs or controllers that KubeBlocks itself needs. It also installs the addons for every database you enabled in `00-config.sh`, but **does not** create the actual database clusters yet.
+
+3. **(Optional) Modify database settings**
+   Before deployment you can edit the `values.yaml` file inside each `<db>/` directory to change `version`, `replicas`, `CPU`, `memory`, `storage size`, etc.
+
+4. **Install the database clusters**
+
+   ```bash
+   bash ./02-install-database.sh
+   ```
+
+   *What the script does*
+   `02-install-database.sh` **actually deploys the chosen databases to Kubernetes**.
+
+   When the script completes, confirm that the clusters are up. It may take a few minutes for all the clusters to become ready,
+   especially if this is the first time running the script as Kubernetes needs to pull container images from registries.
+   You can monitor the progress using the following commands:
+
+   ```bash
+   kubectl get clusters -n rag
+   NAME              CLUSTER-DEFINITION   TERMINATION-POLICY   STATUS    AGE
+   es-cluster                             Delete               Running   11m
+   mongodb-cluster   mongodb              Delete               Running   11m
+   pg-cluster        postgresql           Delete               Running   11m
+   qdrant-cluster    qdrant               Delete               Running   11m
+   redis-cluster     redis                Delete               Running   11m
+   ```
+
+   You can see all the Database `Pods` created by KubeBlocks.
+   Initially, you might see pods in `ContainerCreating` or `Pending` status - this is normal while images are being pulled and containers are starting up.
+   Wait until all pods show `Running` status:
+
+   ```bash
+   kubectl get po -n rag
+   NAME                        READY   STATUS    RESTARTS   AGE
+   es-cluster-mdit-0           2/2     Running   0          11m
+   mongodb-cluster-mongodb-0   2/2     Running   0          11m
+   pg-cluster-postgresql-0     4/4     Running   0          11m
+   pg-cluster-postgresql-1     4/4     Running   0          11m
+   qdrant-cluster-qdrant-0     2/2     Running   0          11m
+   redis-cluster-redis-0       2/2     Running   0          11m
+   ```
+
+   You can also check the detailed status of a specific pod if it's taking longer than expected:
+
+   ```bash
+   kubectl describe pod <pod-name> -n rag
+   ```
+
+## Connect to Databases
+
+To connect to your databases, follow these steps to identify available accounts, retrieve credentials, and establish connections:
+
+### 1. List Available Database Clusters
+
+First, view the database clusters running in your namespace:
+
+```bash
+kubectl get cluster -n rag
+```
+
+### 2. Retrieve Authentication Credentials
+
+For PostgreSQL, retrieve the username and password from Kubernetes secrets:
+
+```bash
+# Get PostgreSQL username
+kubectl get secrets -n rag pg-cluster-postgresql-account-postgres -o jsonpath='{.data.username}' | base64 -d
+# Get PostgreSQL password
+kubectl get secrets -n rag pg-cluster-postgresql-account-postgres -o jsonpath='{.data.password}' | base64 -d
+```
+
+If you have trouble finding the correct secret name, list all secrets:
+
+```bash
+kubectl get secrets -n rag
+```
+
+### 3. Port Forward to Local Machine
+
+Use port forwarding to access PostgreSQL from your local machine:
+
+```bash
+# Forward PostgreSQL port (5432) to your local machine
+# You can see all services with: kubectl get svc -n rag
+kubectl port-forward -n rag svc/pg-cluster-postgresql-postgresql 5432:5432
+```
+
+### 4. Connect Using Database Client
+
+Now you can connect using your preferred PostgreSQL client with the retrieved credentials:
+
+```bash
+# Example: connecting with psql
+export PGUSER=$(kubectl get secrets -n rag pg-cluster-postgresql-account-postgres -o jsonpath='{.data.username}' | base64 -d)
+export PGPASSWORD=$(kubectl get secrets -n rag pg-cluster-postgresql-account-postgres -o jsonpath='{.data.password}' | base64 -d)
+psql -h localhost -p 5432 -U $PGUSER
+```
+
+Keep the port-forwarding terminal running while you're connecting to the database.
+
+
+## Uninstalling
+
+1. **Remove the database clusters**
+
+   ```bash
+   bash ./03-uninstall-database.sh
+   ```
+
+   The script deletes the database clusters that were enabled in `00-config.sh`.
+
+2. **Clean up KubeBlocks add-ons**
+
+   ```bash
+   bash ./04-cleanup.sh
+   ```
+
+   This removes the addons installed by `01-prepare.sh`.

+===========================================
+ LightRAG has been successfully deployed!
+===========================================
+
+View application logs:
+  kubectl logs -f --namespace {{ .Release.Namespace }} deploy/{{ include "lightrag.fullname" . }}
+
+===========================================
+
+Access the application:
+{{- if contains "NodePort" .Values.service.type }}
+  Run these commands to get access information:
+  -----------------------------------------
+  export NODE_PORT=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ include "lightrag.fullname" . }})
+  export NODE_IP=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
+  echo "LightRAG is accessible at: http://$NODE_IP:$NODE_PORT"
+  -----------------------------------------
+{{- else if contains "LoadBalancer" .Values.service.type }}
+  Run these commands to get access information (external IP may take a minute to assign):
+  -----------------------------------------
+  export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ include "lightrag.fullname" . }} --template "{{ "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}" }}")
+  echo "LightRAG is accessible at: http://$SERVICE_IP:{{ .Values.service.port }}"
+  -----------------------------------------
+  If SERVICE_IP is empty, retry the command or check service status with:
+  kubectl get svc --namespace {{ .Release.Namespace }} {{ include "lightrag.fullname" . }}
+{{- else if contains "ClusterIP" .Values.service.type }}
+  For development environments, to access LightRAG from your local machine:
+
+  1. Run this port-forward command in your terminal:
+    kubectl --namespace {{ .Release.Namespace }} port-forward svc/{{ include "lightrag.fullname" . }} {{ .Values.service.port }}:{{ .Values.env.PORT }}
+
+  2. While the command is running, open your browser and navigate to:
+     http://localhost:{{ .Values.service.port }}
+
+  Note: To stop port-forwarding, press Ctrl+C in the terminal.
