eureka啓動類

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

@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {

    public static void main(String[] args) {
        SpringApplication.run( EurekaServerApplication.class, args );
    }

項目搭建之後用idea maven的clean ,install構建出對應的jar包

DockerFile設置

dockerfile文件

FROM openjdk:8-jdk-alpine
VOLUME /tmp
ADD eureka.jar app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

注意eureka.jar的名字要和你打出來的jar包名字保持一致
然後在對應的文件目錄下準備好2個文件：
Dockerfile和eureka.jar

docker命令

docker build -t eureka:my .
docker run --name eureka -p 8761:8761 -d eureka:my

打出對應的docker image並且啓動docker
這樣eureka就啓動了。
