What is the use of Namespace ? 首先必须include相应的类,并且可以设置namespace 。 First we start with including the necessary headers and setting the namespace . 这确保了在发生故障转移之前完全同步Namespace 状态。 This ensures that the namespace state is fully synchronized before a failover occurs. Namespace 把assembly中定义的类组织起来。Namespaces organize the objects defined in an assembly.
容器有自己的networknamespace ,但是没有做任何的网络配置。 Each container has its own network namespace , but has no network configuration. There must be one blank line after the namespace declaration. 减少闲置时间的一个好方法是用Namespace 作为虚拟集群的一种形式。 A good way to reduce idle time is to use namespaces as a form of virtual cluster inside your cluster. A blank line must be inserted after the namespace declaration. 你知道模组(module)和套件(package)之间的区别吗?命名空间套件(namespace packages)?? Do you know the difference between a module and a package? namespace packages? 尽管没有显示出来,但是RSS0.90的feeds同样可以使用namespace ,不过与RSS1.0的不同。 Not shown, but RSS 0.90 feeds also use a namespace , but not the same one as RSS 1.0. Usenamespace 指令可以出现在程序、包定义或类定义的顶层。 The use namespace directive can appear at the top level of a program, package definition. Pod中的所有容器使用同一个网络namespace ,即相同的IP地址和Port空间。 Every container in a Pod shares the network namespace , including the IP address and network ports. Namespace extensions/zh分类包含管理一般名字空间扩展的条目。The Namespace extensions/cs category contains articles on extensions that manage the general namespace. H文件中,您可以使用namespace detail来隐藏应用程序代码不需要的实现细节。 H file, you can use namespace detail to hide implementation details not needed for the application code. Metadata:唯一标识该对象的元数据,包括name,UID,可选的namespace . Metadata- Data that helps uniquely identify the object, including a name string, UID, and optional namespace . W3C的CSS工作组还更新了2011年9月29日发布的CSS名字空间模块(CSSNamespace ModuleLevel3)的推荐标准。 The group also updated in place the 29 September 2011 Recommendation of CSS Namespaces Module Level 3. Metadata-帮助识别对象唯一性的数据,包括一个name字符串、UID和可选的namespace . Metadata- Data that helps uniquely identify the object, including a name string, UID, and optional namespace . 当删除一个Namenode/Namespace 时,与之相关的块池亦会从datanode上删除。 If a NameNode or namespace is deleted, the corresponding block pool which is residing on the DataNodes will also be deleted. Metadata-帮助唯一标识对象的数据,包括name字符串、uid和可选的'namespace ''. Metadata- Data that helps uniquely identify the object, including a name string, UID, and optional namespace . Namespace 与DNS密切相关,因为位于同一Namespace内的服务可以通过其名称进行访问。Namespaces are closely related to DNS because services located within the same namespace are accessible through their names. Winsock2SPI有两种类型的serviceproviders--transport和namespace 。 The Winsock 2 SPI allows software developers to create two different types of service providers- transport and namespace . 而且,namespace 对象,像是console,可以被并发线程访问,因为他们刚好可以使用JS对象模型。 Additionally, namespace objects like console can be accessed by concurrent threads because they can just use the JS object model. 如果你用的WindowsServer没有安装DFSNamespace 角色服务,你也可以将DFSUTIL.EXE安装上去。 If you are using a Windows Server that is not running the DFS Namespace role service, you can also get DFSUTIL. EXE installed. Windows容器间的网络更加复杂,因为每个容器都有自己的网络namespace ,所以推荐使用单个容器pod。 Networking between Windows containers is more complicated because each container gets its own network namespace , so it's recommended that you use single-container pods for now. 如果对整个文件使用相同的namespace,并且没有其他重要的东西,则namespace 中不需要偏移量。 If the same namespace is used for the entire file, and there isn't anything else significant, an offset is not necessary inside namespace . 另外,Namespace 可以有资源配额:每个虚拟集群都可以接收固定的分配,以避免Namespace 之间的资源竞争。 In addition, namespaces can have resource quotas: each virtual cluster can receive a defined allocation in order to avoid a resource competition between namespaces . Service,pod,replicationcontroller和volume可以很容易地和namespace 配合工作,但是namespace 为集群中的组件间提供了一定程度的隔离。 Pods, volumes, ReplicaSets, and services can easily cooperate within a namespace , but the namespace provides an isolation from the other parts of the cluster. 每个Namespace 都是Kubernetes内部一个完全隔离的空间,这意味着可以根据需要创建多个环境,例如production环境或staging环境。 Each namespace is a completely isolated space inside Kubernetes, which means several environments can be created as necessary, such as production environments or staging environments.
