感谢使用 DataFlow Pro! 🚀

19. `helm/README.md` - Helm使用文档

# DataFlow Pro Helm Chart

DataFlow Pro的官方Helm Chart，用于在Kubernetes集群中部署企业级数据流水线编排系统。

## 📋 前置条件

- Kubernetes 1.19+
- Helm 3.0+
- PV provisioner支持（用于持久化存储）

## 🚀 快速开始

### 1. 添加Helm仓库

```bash
helm repo add dataflow https://charts.dreamvfia.com
helm repo update

2. 安装Chart

# 使用默认配置安装
helm install dataflow dataflow/dataflow-pro

# 使用自定义配置安装
helm install dataflow dataflow/dataflow-pro -f values-prod.yaml

# 指定命名空间
helm install dataflow dataflow/dataflow-pro -n dataflow-prod --create-namespace

3. 升级Chart

helm upgrade dataflow dataflow/dataflow-pro -f values-prod.yaml

4. 卸载Chart

helm uninstall dataflow -n dataflow-prod

`mongodb.auth.rootPassword`	Root密码	`changeme`
`mongodb.auth.password`	用户密码	`changeme`

📝 使用示例

开发环境部署

helm install dataflow ./helm \
  --namespace dataflow-dev \
  --create-namespace \
  --values helm/values-dev.yaml

生产环境部署

helm install dataflow ./helm \
  --namespace dataflow-prod \
  --create-namespace \
  --values helm/values-prod.yaml \
  --set postgresql.auth.password=<secure-password> \
  --set redis.auth.password=<secure-password> \
  --set mongodb.auth.rootPassword=<secure-password>

自定义配置

创建 my-values.yaml:

replicaCount: 5

resources:
  limits:
    cpu: 4000m
    memory: 4Gi

ingress:
  hosts:
    - host: dataflow.mycompany.com
      paths:
        - path: /
          pathType: Prefix

部署:

helm install dataflow ./helm -f my-values.yaml

🔧 故障排查

查看Pod状态

kubectl get pods -n dataflow-prod

查看日志

kubectl logs -n dataflow-prod -l app.kubernetes.io/name=dataflow-pro -f

查看事件

kubectl get events -n dataflow-prod --sort-by='.lastTimestamp'

## 🎯 Helm Chart使用指南

### 1. 本地开发测试

```bash
# 验证Chart语法
helm lint ./helm

# 模板渲染测试
helm template dataflow ./helm --debug

# 使用开发配置渲染
helm template dataflow ./helm -f helm/values-dev.yaml

2. 安装到开发环境

# 创建命名空间
kubectl create namespace dataflow-dev

# 安装
helm install dataflow ./helm \
  --namespace dataflow-dev \
  --values helm/values-dev.yaml \
  --dry-run --debug  # 先测试

# 实际安装
helm install dataflow ./helm \
  --namespace dataflow-dev \
  --values helm/values-dev.yaml

3. 升级到生产环境

# 安装到生产
helm install dataflow ./helm \
  --namespace dataflow-prod \
  --create-namespace \
  --values helm/values-prod.yaml \
  --set postgresql.auth.password=$DB_PASSWORD \
  --set redis.auth.password=$REDIS_PASSWORD \
  --set mongodb.auth.rootPassword=$MONGO_PASSWORD

# 升级
helm upgrade dataflow ./helm \
  --namespace dataflow-prod \
  --values helm/values-prod.yaml \
  --reuse-values

4. 打包和发布

# 打包Chart
helm package ./helm

# 生成索引
helm repo index .

# 推送到Chart仓库
# (需要配置Chart仓库)
