Kubernetes学习笔记-移除Nacos迁移至K8s

article 2025/3/16 12:59:02

项目服务的配置管理和服务注册发现由原先的Nacos全面迁移到Kubernetes上。

一、移除Nacos

移除Nacos组件依赖。

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
</dependency>

移除Nacos配置。正常情况下配置位于bootstrap.yml文件。

spring:
  cloud:
    nacos:
      discovery:
        register-enabled: true
        server-addr: ${NACOS_HOST}
        username: ${NACOS_USERNAME}
        password: ${NACOS_PASSWORD}
        namespace: ${NACOS_NAMESPACE}
        group: ${NACOS_GROUP}
        weight: 1
        metadata:
          management:
            context-path: ${server.servlet.context-path}/actuator
      config:
        enabled: true
        server-addr: ${NACOS_HOST}
        username: ${NACOS_USERNAME}
        password: ${NACOS_PASSWORD}
        namespace: ${NACOS_NAMESPACE}
        group: ${NACOS_GROUP}
        prefix: ${spring.application.name}
        file-extension: yml
        encode: UTF-8
        shared-configs:
          - data-id: common-config.yml
            group: ${NACOS_GROUP}
            refresh: true

二、引入Kubernetes

引入Kubernetes组件依赖。

<!-- Kubernetes依赖包 -->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-kubernetes</artifactId>
    <version>1.1.10.RELEASE</version>
</dependency>

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-kubernetes-config</artifactId>
    <version>1.1.10.RELEASE</version>
</dependency>

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-kubernetes-ribbon</artifactId>
    <version>1.1.10.RELEASE</version>
</dependency>

引入Kubernetes配置。通常情况下修改bootstrap.yml文件。需要先把Nacos上的项目服务配置信息迁移至Kubernetes的ConfigMap上。

spring:
  cloud:
    kubernetes:
      discovery:
        enabled: true
        all-namespaces: true
      config:
        sources:
          - name: common-config
            namespace: default
          - name: service-config
            namespace: default
      reload:
        enabled: true
        monitoring-config-maps: true
        monitoring-secrets: true
        strategy: refresh
        mode: event
