快速部署	分钟级集群部署和扩缩容	提升业务响应速度
资源隔离	基于cgroup的精细资源控制	保证关键业务稳定性
弹性伸缩	根据负载动态调整实例数量	优化资源利用率

Docker部署方案

1. All-in-One模式（开发测试）

适用于开发测试环境的单容器部署方案：

# 构建All-in-One镜像
DOCKER_BUILDKIT=1 docker build \
  --build-arg ARTIFACT_SOURCE=image \
  --build-arg ARTIFACTIMAGE=ghcr.io/starrocks/starrocks/artifact-ubuntu:main \
  -f docker/dockerfiles/allin1/allin1-ubuntu.Dockerfile \
  -t starrocks-allinone:latest \
  ./

启动容器：

docker run -d \
  --name starrocks-allinone \
  -p 9030:9030 \    # MySQL协议端口
  -p 8030:8030 \    # HTTP协议端口
  -p 8040:8040 \    # BE HTTP端口
  -v /path/to/data:/opt/starrocks/data \
  starrocks-allinone:latest

2. 组件分离模式（生产环境）

FE节点部署

# 构建FE镜像
DOCKER_BUILDKIT=1 docker build \
  -f docker/dockerfiles/fe/fe-ubuntu.Dockerfile \
  -t starrocks-fe:latest \
  ./

BE节点部署

# 构建BE镜像
DOCKER_BUILDKIT=1 docker build \
  -f docker/dockerfiles/be/be-ubuntu.Dockerfile \
  -t starrocks-be:latest \
  ./

3. Docker Compose集群部署

创建多节点StarRocks集群：

version: '3.8'
services:
  fe:
    image: starrocks-fe:latest
    container_name: starrocks-fe
    ports:
      - "9030:9030"
      - "8030:8030"
    environment:
      - FE_SERVERS=fe:9010
    volumes:
      - fe-data:/opt/starrocks/fe
    networks:
      - starrocks-net

  be1:
    image: starrocks-be:latest
    container_name: starrocks-be1
    environment:
      - FE_HOST=fe
      - FE_PORT=9010
    volumes:
      - be1-data:/opt/starrocks/be
    networks:
      - starrocks-net
    depends_on:
      - fe

  be2:
    image: starrocks-be:latest
    container_name: starrocks-be2
    environment:
      - FE_HOST=fe
      - FE_PORT=9010
    volumes:
      - be2-data:/opt/starrocks/be
    networks:
      - starrocks-net
    depends_on:
      - fe

volumes:
  fe-data:
  be1-data:
  be2-data:

networks:
  starrocks-net:
    driver: bridge

Kubernetes集成方案

1. StatefulSet部署架构

      - name: be
        image: starrocks-be:latest
        ports:
        - containerPort: 9060
          name: be
        - containerPort: 8040
          name: http
        volumeMounts:
        - name: be-data
          mountPath: /opt/starrocks/be/storage
        - name: be-log
          mountPath: /opt/starrocks/be/log
        env:
        - name: FE_SERVICE
          value: "starrocks-fe"
        - name: FE_PORT
          value: "9010"
        resources:
          requests:
            memory: "16Gi"
            cpu: "4"
          limits:
            memory: "32Gi"
            cpu: "8"
  volumeClaimTemplates:
  - metadata:
      name: be-data
    spec:
      accessModes: [ "ReadWriteOnce" ]
      storageClassName: "fast-ssd"
      resources:

      name: be-log
    spec:
      accessModes: [ "ReadWriteOnce" ]
      storageClassName: "standard"
      resources:
        requests:
          storage: 50Gi

4. Service配置

apiVersion: v1
kind: Service
metadata:
  name: starrocks-fe
  labels:
    app: starrocks
    component: fe
spec:
  selector:
    app: starrocks

    port: 9030
    targetPort: 9030
  - name: http
    port: 8030
    targetPort: 8030
  type: LoadBalancer

---
apiVersion: v1
kind: Service
metadata:
  name: starrocks-be
  labels:
    app: starrocks
    component: be
spec:
  selector:
    app: starrocks
    component: be
  ports:

    port: 9060
    targetPort: 9060
  - name: http
    port: 8040
    targetPort: 8040
  clusterIP: None

生产环境最佳实践

1. 资源规划建议

组件	CPU	内存	存储	副本数
FE节点	4核	8GB	100GB SSD	3（奇数）
BE节点	8核	32GB	1TB SSD	根据数据量
CN节点	16核	64GB	50GB SSD	动态伸缩

2. 高可用配置

# FE高可用配置
apiVersion: policy/v1
kind: PodDisruptionBudget
metadata:
  name: starrocks-fe-pdb
spec:
  minAvailable: 2
  selector:
    matchLabels:
      app: starrocks
      component: fe

# BE高可用配置
apiVersion: policy/v1
kind: PodDisruptionBudget
metadata:
  name: starrocks-be-pdb
spec:
  minAvailable: 3
  selector:
    matchLabels:
      app: starrocks
      component: be

3. 监控与告警

apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  name: starrocks-monitor
  labels:
    app: starrocks
spec:
  selector:
    matchLabels:
      app: starrocks
  endpoints:
  - port: http
    interval: 30s
    path: /metrics
  namespaceSelector:
    any: true

4. 备份与恢复策略

# 数据备份脚本
#!/bin/bash
# 备份元数据
kubectl exec deployment/starrocks-fe -- \
  /opt/starrocks/fe/bin/backup_meta.sh /backup/meta_$(date +%Y%m%d).tar.gz

# 备份数据快照
for be_pod in $(kubectl get pods -l component=be -o name); do
  kubectl exec $be_pod -- \
    /opt/starrocks/be/bin/make_snapshot.sh /backup/snapshot_$(date +%Y%m%d)
done

性能优化指南

1. 容器级别优化

# 内核参数优化
securityContext:
  sysctls:
  - name: net.core.somaxconn
    value: "65535"
  - name: net.ipv4.tcp_max_syn_backlog
    value: "65535"
  - name: vm.swappiness
    value: "10"

# CPU亲和性
affinity:
  podAntiAffinity:
    preferredDuringSchedulingIgnoredDuringExecution:
    - weight: 100
      podAffinityTerm:
        labelSelector:
          matchExpressions:
          - key: app
            operator: In
            values:
            - starrocks
        topologyKey: kubernetes.io/hostname

2. 存储优化

# 使用本地SSD存储
volumeClaimTemplates:
- metadata:
    name: be-data
  spec:
    accessModes: [ "ReadWriteOnce" ]
    storageClassName: "local-ssd"
    resources:
      requests:
        storage: 1Ti
    selector:
      matchLabels:
        type: local-ssd

3. 网络优化

# 使用高性能网络CNI
annotations:
  k8s.v1.cni.cncf.io/networks: macvlan-conf
  k8s.v1.cni.cncf.io/network-status: |
    [{
      "name": "macvlan-conf",
      "interface": "net1",
      "ips": ["192.168.1.100"],
      "mac": "aa:bb:cc:dd:ee:ff",
      "default": false
    }]

故障排查与维护

常见问题处理

问题现象	可能原因	解决方案
FE节点启动失败	元数据损坏	从备份恢复元数据
BE节点无法注册	网络连通性问题	检查Service和网络策略
查询性能下降	资源不足	调整资源限制和请求
存储空间不足	数据增长过快	扩容PVC或清理旧数据

日常维护命令

# 查看集群状态
kubectl exec deployment/starrocks-fe -- \
  /opt/starrocks/fe/bin/show_frontends.sh

# 查看BE节点状态
kubectl exec deployment/starrocks-fe -- \
  /opt/starrocks/fe/bin/show_backends.sh

# 集群扩容
kubectl scale statefulset starrocks-be --replicas=8

# 日志查看
kubectl logs -l component=fe --tail=100
kubectl logs -l component=be --tail=100
