前置环境

配置依赖

配置域名（可选）

address=/sentinel.basic.tanqidi.com/172.31.0.100
address=/sentinel.dev.tanqidi.com/172.31.0.100

1. 镜像构建

https://github.com/alibaba/Sentinel/releases

https://sentinelguard.io/zh-cn/docs/introduction.html

docker build -t tanqidi/sentinel-service .

我帮你下载好了：sentinel-dashboard-1.8.8.jar

# 使用 OpenJDK 11 作为基础镜像
FROM openjdk:11-jre-slim

# 设置工作目录
WORKDIR /app

# 复制 Sentinel 服务的 JAR 包到容器中
COPY sentinel-dashboard-1.8.8.jar /app/sentinel-service.jar

# 暴露服务使用的端口（根据你的应用设置调整）
EXPOSE 8080

# 设置环境变量（根据需要调整）
ENV JAVA_OPTS="-Xms512m -Xmx512m"

# 启动 Sentinel 服务
ENTRYPOINT ["sh", "-c", "java $JAVA_OPTS -jar /app/sentinel-service.jar"]

2. docker 部署

默认账号密码都是 sentinel

# 8080太常见了容易冲突，我使用8333来试验
docker run -d --name sentinel-service -p 8333:8080 \
  -e JAVA_OPTS="-Dsentinel.dashboard.auth.username=admin -Dsentinel.dashboard.auth.password=123456" \
  tanqidi/sentinel-service

3. kubernetes 部署

3.1 configmap

如果不配置的话，默认的账号密码都是sentinel

https://sentinelguard.io/zh-cn/docs/introduction.html

kind: ConfigMap
apiVersion: v1
metadata:
  name: sentinel-conf
  namespace: basic
  annotations:
    kubesphere.io/creator: admin
data:
  JAVA_OPTS: |-
    -Dsentinel.dashboard.auth.username=admin
    -Dsentinel.dashboard.auth.password=123456

3.2 deployment

kind: Deployment
apiVersion: apps/v1
metadata:
  name: sentinel-service
  namespace: basic
  labels:
    app: sentinel-service
  annotations:
    deployment.kubernetes.io/revision: '1'

      annotations:
        kubesphere.io/creator: admin
        kubesphere.io/imagepullsecrets: '{}'
    spec:
      volumes:
        - name: host-time
          hostPath:
            path: /etc/localtime
            type: ''
      containers:
        - name: container-3ikwrh
          image: registry.cn-hangzhou.aliyuncs.com/tanqidi/sentinel-service
          ports:
            - name: tcp-8080
              containerPort: 8080
              protocol: TCP
          env:
            - name: JAVA_OPTS
              valueFrom:
                configMapKeyRef:
                  name: sentinel-conf
                  key: JAVA_OPTS
          resources: {}
          volumeMounts:
            - name: host-time
              readOnly: true
              mountPath: /etc/localtime
          terminationMessagePath: /dev/termination-log
          terminationMessagePolicy: File

      restartPolicy: Always
      terminationGracePeriodSeconds: 30

    rollingUpdate:
      maxUnavailable: 25%
      maxSurge: 25%

3.3 service

使用NodePort来试验访问

kind: Service
apiVersion: v1
metadata:
  name: sentinel-service
  namespace: basic
  labels:
    app: sentinel-service
  annotations:
    kubesphere.io/creator: admin
spec:
  ports:
    - name: http-8080
      protocol: TCP
      port: 8080
      targetPort: 8080
      nodePort: 32263
  selector:
    app: sentinel-service
  type: NodePort
  sessionAffinity: None
  externalTrafficPolicy: Cluster
  ipFamilies:
    - IPv4
  ipFamilyPolicy: SingleStack
  internalTrafficPolicy: Cluster

3.4 coredns

rewrite name sentinel.basic.tanqidi.com sentinel.basic.svc.cluster.local

4. 镜像制品

  • tanqidi/sentinel-service

  • registry.cn-hangzhou.aliyuncs.com/tanqidi/sentinel-service

5. 写在最后

通过JAVA_OPTS变量来传递运行参数能很好的控制它运行了，具体的话各位可以看官网怎么配置就好了。
