多克尔-Compose.yml

Question

这是我的Eureka服务器 application.property

# set port
server.port=8761
# no need to register the server with the server
eureka.client.register-with-eureka=false
# don't need a local copy of the registry
eureka.client.fetch-registry=false

Eureka Server dockerfile

FROM openjdk:8
ADD target/eureka-service.jar eureka-service.jar
EXPOSE 8761
ENTRYPOINT ["java", "-jar", "eureka-service.jar"]

Eureka Client application.property

eureka.client.serviceUrl.defaultZone= http://localhost:8761/eureka/
eureka.client.registerWithEureka=true
eureka.client.fetchRegistry=true

Eureka Client dockerfile

FROM openjdk:8
ADD target/foo.jar foo.jar
EXPOSE 8971
ENTRYPOINT ["java", "-jar", "foo.jar"]

Eureka服务器使用 @EnableEurekaServer 进行注释，Eureka客户端使用 @EnableEurekaClient 进行注释

客户端已成功注册EurekaServer，一切正常。但是当我尝试使用下面的

在Docker中运行它时

多克尔-Compose.yml

版本：＆＃34; 2.0＆＃34;

services:
 foo-service:
  build: foo/
  ports: 
  - "8761:8761"

 bar-service:
  build: bar/
  ports: 
  - "8971:8971"

客户端无法注册服务器。并且低于stacktrace。

我真的是Docker中的新人，有什么帮助吗？

Answer 1

将+--------+--------+ | testID | Status | +--------+--------+ | 1 | fail | | 2 | pass | | 3 | fail | +--------+--------+中的update Table1 a inner join ( select b.testID, iif(min(b.status)=max(b.status) and min(b.status)='pass','pass','fail') as v from Table2 b group by b.testID ) c on a.testID = c.testID set a.testStatus = c.v修改为：

testID

将$aa=array("a" => 1, "b" => 2, "c" =>3, "d" => 4); foreach($aa as $value) { $temp[]=$value; } echo implode(",",$temp);中的dockerfile修改为：

EurekaServer

在FROM openjdk:8 ADD target/eureka-service.jar eureka-service.jar EXPOSE 8761 ENTRYPOINT java -jar Eureka-0.0.1-SNAPSHOT.jar eureka的属性文件中，修改此属性

dockerfile

现在分别为两个应用程序构建映像。在EurekaClient中，您将需要添加一些配置以将客户端与服务器链接。修改后的docker-compose如下所示：

FROM openjdk:8
ADD target/foo.jar foo.jar
EXPOSE 8971
ENTRYPOINT java -jar foo.jar foo

干杯！
