如何通过YAML在K8s中部署AppSmith？求生产环境非Helm部署YAML示例

前置准备 #

• 确保你的Kubernetes集群处于健康状态，可用kubectl cluster-info验证
• 拥有集群管理员权限，用于创建命名空间、存储卷等资源
• 集群已配置持久化存储类（StorageClass），生产环境依赖持久化存储避免数据丢失

部署步骤 #

1. 创建专属命名空间

先为AppSmith创建独立命名空间，隔离资源：

kubectl create namespace appsmith

2. 部署核心组件（完整YAML示例）

将以下内容保存为appsmith-production.yaml，执行kubectl apply -f appsmith-production.yaml -n appsmith完成部署。该配置包含生产环境所需的MongoDB、Redis、AppSmith主服务及配套资源：

# 1. ConfigMap：存储非敏感配置
apiVersion: v1
kind: ConfigMap
metadata:
  name: appsmith-config
data:
  APPSMITH_MONGODB_URI: "mongodb://appsmith-mongodb:27017/appsmith"
  APPSMITH_REDIS_URL: "redis://appsmith-redis:6379"
  APPSMITH_SERVER_URL: "http://your-domain.com" # 替换为实际访问域名/IP
  APPSMITH_ENV: "production"

---

# 2. Secret：存储敏感信息（替换为实际密码，需base64编码）
apiVersion: v1
kind: Secret
metadata:
  name: appsmith-secrets
type: Opaque
data:
  MONGODB_ROOT_PASSWORD: "bXktc2VjcmV0LXBhc3N3b3Jk" # 生成方式：echo -n "your-password" | base64
  APPSMITH_ENCRYPTION_PASSWORD: "bXktZW5jcnlwdGlvbi1wYXNzd29yZA==" # 务必设置强加密密钥

---

# 3. MongoDB StatefulSet及Service（生产环境用StatefulSet保证数据一致性）
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: appsmith-mongodb
spec:
  serviceName: appsmith-mongodb
  replicas: 1

# 6. AppSmith访问Service（根据集群环境选择类型）
apiVersion: v1
kind: Service
metadata:
  name: appsmith-service
spec:
  type: LoadBalancer # 集群支持则用，否则换为NodePort或ClusterIP配合Ingress
  selector:
    app: appsmith
  ports:
  - port: 80
    targetPort: 80
    nodePort: 30080 # 用NodePort时可指定端口（可选）

关键配置说明 #

• 持久化存储：所有核心组件配置PVC，保证Pod重启/迁移时数据不丢失，生产环境需确认集群有可用StorageClass
• 资源限制：为容器设置CPU、内存的请求与限制，避免资源抢占影响稳定性
• 健康探针：配置liveness/readiness探针，Kubernetes自动检测服务状态并重启异常Pod
• 敏感信息：密码存储在Secret中避免明文泄露，ConfigMap存储非敏感配置便于修改
• 多副本：AppSmith主服务设置2副本，MongoDB用StatefulSet保证数据一致性

验证部署 #

部署完成后执行以下命令确认状态：

# 查看所有Pod状态
kubectl get pods -n appsmith

# 查看Service访问地址（LoadBalancer类型）
kubectl get service appsmith-service -n appsmith

待所有Pod变为Running状态后，即可通过Service外部IP或配置的域名访问AppSmith。
