在Docker容器中运行eureka服务 [英] Run eureka service in a docker container
问题描述
我想将eureka-server作为容器运行，并希望稍后让其他微服务注册到该容器.但是我遇到了一些问题，让它作为容器运行并访问它.该应用程序在STS中运行没有问题.当我在STS中执行它时，可以使用localhost:8761访问eureka-server.
I want to run eureka-server as container and want to let other microservices register to this container later on. But I got some issues to let it run as container and access it. The application is running in STS without issues. When I execute it in STS I can access the eureka-server using localhost:8761.
application.java:
package hello;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@EnableEurekaServer
@SpringBootApplication
public class EurekaServiceApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServiceApplication.class, args);
}
}
application.yml:
server:
port: 8761
eureka:
client:
registerWithEureka: false
fetchRegistry: false
bootstrap.yml:
spring:
application:
name: eureka-service
Dockerfile:

What am I doing:
- 运行
mvn package && java -jar target/eureka-service-0.1.0.jar进行构建
罐子里在此期间，Spring Boot应用程序和我必须停止此操作 使用 ctrl + c .图像已在target文件夹中创建. - 使用
mvn install dockerfile:build构建图像.图像已构建. - 使用
docker run -p 8080:8080 -t microservice/eureka- service运行创建的图像
-
这是docker bash的响应:
- running
mvn package && java -jar target/eureka-service-0.1.0.jarto build
the jar. During this the spring boot application and I have to stop this using ctrl+c. The image has been created in thetargetfolder. - building image using
mvn install dockerfile:build. Image has been built. - run the created image using
docker run -p 8080:8080 -t microservice/eureka- service This is the response of the docker bash:
2018-03-23 15:28:05.618 INFO 1 --- [ main]

通知2018-03-23 15:31:05.476 INFO 1 --- [a-EvictionTimer] c.n.e.registry.AbstractInstanceRegistry : Running the evict task with compensationTime 1ms大约每分钟一次通过bash返回.
如果尝试在浏览器中使用192.168.99.100:8080调用eureka-server，它说我无法访问此页面.
当我使用 ctrl + c 结束应用程序时，我可以查看所有正在运行的容器，bash告诉我microservice/eureka-service容器仍在运行.仍然无法访问它.
The notification 2018-03-23 15:31:05.476 INFO 1 --- [a-EvictionTimer] c.n.e.registry.AbstractInstanceRegistry : Running the evict task with compensationTime 1ms returns by the bash about once a minute.
If I try to call the eureka-serverusing 192.168.99.100:8080 in the browser it says I can't access this page.
When I end the application using ctrl+c I can view all running containers and the bash tells me the container microservice/eureka-service is still running. Still can not access it tho.
推荐答案
server:
port: 8761
您的application.yml中有该文件.这意味着应用程序在端口8761而不是8080
You have that in your application.yml. Which means the application is running on port 8761 not 8080
您应该尝试docker run -p 8761:8761 -t microservice/eureka-service
