我可以在Dockerfile中指定端口范围

EXPOSE 7000-8000

并且在运行容器时将所有这些暴露的端口绑定到主机上的相同端口？

docker run -p 7000-8000:7000-8000

在RedHat Linux 6.2上,我正在运行free -m,它显示几乎所有8GB使用的

             total       used       free     shared    buffers     cached
Mem:          7989       7734        254          0         28       7128

Swap:         4150          0       4150

但同时在top -M我看不到使用所有这些内存的任何进程:

我希望我的默认活动配置文件是productionif if -Dspring.profiles.activenot set.

我尝试了以下内容,application.properties但它不起作用:

spring.profiles.default=production

Spring-boot版本= 1.3.5.RELEASE

我有一个地方一个Dockerfile ARG在使用CMD指令:

ARG MASTER_NAME
CMD spark-submit --deploy-mode client --master ${MASTER_URL}

arg通过docker-compose传递:

  spark:
    build:
      context: spark
      args:
        - MASTER_URL=spark://master:7077

但是,ARG似乎没有得到扩展CMD.在我之后docker-compose up.

以下是检查显示的内容:

docker inspect  -f "{{.Name}} {{.Config.Cmd}}" $(docker ps -a -q)
/spark {[/bin/sh -c spark-submit --deploy-mode client --master ${MASTER_URL}]}

学习Java 8 Lambdas,只是想知道编译器如何知道Comparator中哪个方法用于lambda表达式？它似乎不是SAM接口？它有2个抽象方法:

@FunctionalInterface
public interface Comparator<T> {
    int compare(T o1, T o2);
    boolean equals(Object obj);
}

我正在尝试在一个控制台窗口上运行taskkill,该窗口的标题中有空格.如何将此窗口标题传递给taskkill.我尝试过以下方法:

taskkill /fi "WINDOWTITLE eq Administrator: My Window Title"

我有这个Singleton:

   public enum Elvis {
       INSTANCE;
       private int age;

       public int getAge() {
           return age;
       }
   }

我知道如何在spring中创建枚举bean:

   <bean id="elvis" class="com.xyz.Elvis" factory-method="valueOf">
           <constructor-arg>
               <value>INSTANCE</value>
           </constructor-arg>
   </bean> 

如何将INSTANCE.getAge()返回的int传递给另一个bean构造函数？

我在我的pom中指定了以下SCM标签.但是,当我release:prepare创建maven时,创建的标签的版本为1.0-SNAPSHOT而不是1.0

有任何想法吗？

 <scm>
    <connection>scm:git:https://<username>@bitbucket.org/<username>/<repo>.git</connection>
    <developerConnection>scm:git:https://<username>@bitbucket.org/<username>/<repo>.git</developerConnection>
