一 在windows中使用maven构建microservice-discovery-eureka可运行的jar包

• 
  
  C:\WINDOWS\system32>cd F:\springcloud\temp\microservice-discovery-eureka
  
  
• 
  
  C:\WINDOWS\system32>f:
  
  
• 
  
  F:\springcloud\temp\microservice-discovery-eureka>mvn clean package
  
  
  

在F:\springcloud\temp\microservice-discovery-eureka\target目录生成文件microservice-discovery-eureka-0.0.1-SNAPSHOT.jar
二 将microservice-discovery-eureka-0.0.1-SNAPSHOT.jar拷贝到Linux环境

• 
  
  [root@master eureka]# ll
  
  
• 
  
  total 40952
  
  
• 
  
  -rw-r--r-- 1 root root 41929619 Jul  7 14:29 microservice-discovery-eureka-0.0.1-SNAPSHOT.jar
  
  
  

三 在microservice-discovery-eureka-0.0.1-SNAPSHOT.jar所在的目录创建Dockerfile文件，内容如下

• 
  
  FROM java:8
  
  
• 
  
  VOLUME /tmp
  
  
• 
  
  ADD microservice-discovery-eureka-0.0.1-SNAPSHOT.jar app.jar
  
  
• 
  
  RUN bash -c 'touch /app.jar'
  
  
• 
  
  EXPOSE 8761
  
  
• 
  
  ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
  
  
  

四 使用docker build命令构建镜像

• 
  
  [root@master eureka]# docker build -t cakin24/microservice-discovery-eureka-0.0.1 .
  
  
• 
  
  Sending build context to Docker daemon  41.93MB
  
  
• 
  
  Step 1/6 : FROM java:8
