eureka-seerver 的docker启动

eureka-seerver的docker启动

1.创建eureka-seerver 的服务

• pom.xml配置

        <relativePath/> <!-- lookup parent from repository -->

            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
            <version>2.2.10.RELEASE</version>
        </dependency>
    </dependencies>


    <build>
        <plugins>
            <!-- 打包方式：spring-boot-maven-plugin -->
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>org.fxl.erueka.EurekaServerApplication</mainClass>
                    <finalName>${project.artifactId}</finalName>
                </configuration>
            </plugin>


        </plugins>
    </build>
</project>

• 启动文件

package org.fxl.erueka;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@EnableEurekaServer // 加上启用Eureka服务注解（标记其为Eureka服务）
@SpringBootApplication
public class EurekaServerApplication {
    public static void main(String[] args) {
        SpringApplication.run(EurekaServerApplication.class,args);
    }
}

• resource/appliaction.yml 配置

server:
  port: 8761 # 端口
spring:
  application:
    name: eureka-server # 应用名称，会在Eureka中显示
eureka:
  client:
    register-with-eureka: false # 是否注册自己的信息到EurekaServer，默认是true
    fetch-registry: false # 是否拉取其它服务的信息，默认是true
    service-url: # EurekaServer的地址，现在是自己的地址，如果是集群，需要加上其它Server的地址。
      defaultZone: http://localhost:${server.port}/eureka

• 本地启动测试

2.构建Dockerfile文件

• Dockerfile文件

FROM openjdk:8-jdk-alpine
ENV TZ=Asia/Shanghai
# 设置时区
RUN apk update && apk add --no-cache tzdata && \
    cp /usr/share/zoneinfo/$TZ /etc/localtime && \
    echo "$TZ" > /etc/timezone

COPY ./target/org-eureka-server.jar /org-eureka-server.jar

# 端口宿主机10000：容器8761，实际没有生效，需要docker run时指定端口
# EXPOSE 10000:8761

# ENTRYPOINT 启动命令
ENTRYPOINT [ "java" ,"-jar" , "/org-eureka-server.jar"]

# 相当于： java -jar org-eureka-server.jar

• 构建docker镜像

docker build -t eureka . 

• 启动docker

 docker run --name eureka --restart always  -p 10000:8761 -d 镜像id
