微服務-SpringCloud的Eureka注冊中心+Docker整合部署（六）

一、建立spring cloud工程eureka_server

 EurekaServerApplication.java

 application.yml

server:
  port: 8761

eureka:
  instance:
    hostname: localhost
  client:
  #聲明自己是個服務端
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

#  server:
#    enable-self-preservation: false
           

二、使用Docker打包注冊中心，上傳私有鏡像倉庫并部署

1、新增maven插件

<properties>
		   <docker.image.prefix>yuan</docker.image.prefix>
		</properties>
		<build>
			<finalName>docker-demo</finalName>
		    <plugins>
		        <plugin>
		            <groupId>com.spotify</groupId>
		            <artifactId>dockerfile-maven-plugin</artifactId>
		            <version>1.3.6</version>
		            <configuration>
		                <repository>${docker.image.prefix}/${project.artifactId}</repository>
		                <buildArgs>
		                    <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
		                </buildArgs>
		            </configuration>
		        </plugin>
		    </plugins>
		</build>
           

2、建立Dockerfile

FROM openjdk:8-jdk-alpine
VOLUME /tmp
ARG JAR_FILE
COPY ${JAR_FILE} app.jar
ENTRYPOINT ["java","-jar","/app.jar"]
           

3、打包：

mvn install dockerfile:build

4、推送阿裡雲鏡像倉庫

 阿裡雲鏡像倉庫：阿裡雲登入 - 歡迎登入阿裡雲，安全穩定的雲計算服務平台

docker login --username=andy淩冰 registry.cn-hangzhou.aliyuncs.com

docker tag e528d16e3aa4 registry.cn-hangzhou.aliyuncs.com/hsx_hub/nginx-docker:eureka-v20210913

docker push registry.cn-hangzhou.aliyuncs.com/hsx_hub/nginx-docker:eureka-v20210913

 5、檢視日志 docker logs -f  containerid

docker logs -f d31487e31972c86691394e04cc90b8d487184855b41d7d491d3273d6a5683877
