Kubernetes学习笔记-移除Nacos迁移至K8s

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: trueserver-addr: ${NACOS_HOST}username: ${NACOS_USERNAME}password: ${NACOS_PASSWORD}namespace: ${NACOS_NAMESPACE}group: ${NACOS_GROUP}weight: 1metadata:management:context-path: ${server.servlet.context-path}/actuatorconfig:enabled: trueserver-addr: ${NACOS_HOST}username: ${NACOS_USERNAME}password: ${NACOS_PASSWORD}namespace: ${NACOS_NAMESPACE}group: ${NACOS_GROUP}prefix: ${spring.application.name}file-extension: ymlencode: UTF-8shared-configs:- data-id: common-config.ymlgroup: ${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: trueall-namespaces: trueconfig:sources:- name: common-confignamespace: default- name: service-confignamespace: defaultreload:enabled: truemonitoring-config-maps: truemonitoring-secrets: truestrategy: refreshmode: event
