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: 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
