毫无疑问，Kubernetes 已经成为容器领域当之无愧的事实标准。除了 Google、Microsoft 等技术巨擘们在容器领域里多年的博弈外，国内的 BAT、滴滴、蚂蚁、今日头条等技术大厂，也都已将容器和 Kubernetes 列入未来的战略重心，无数中小型企业也正走在容器化的道路上。 一个很长但精彩的故事 打包发布阶段 在docker 之前有一个 cloud foundry Paas项目，使用 cf push 将用户的可执行文件和 启动脚本打进一个压缩包内，上传到cloud foundry 的存储中，然后cloud foundry 会通过调度器选择一个可以运行这个应用的虚拟机，然后通知这个机器上的agent 把应用压缩包下载下来启动。由于需要在一个虚拟机中 启动不同用户的应用，cloud foundry为客户的应用单独创建一个称作沙盒的隔离环境，然后在沙盒中启动这些应用进程。 PaaS 主要是提供了一种名叫“应用托管”的能力。虚拟机技术发展 ==> 客户不自己维护物理机、转而购买虚拟机服务，按需使用 ==> 应用需要部署到云端 ==> 部署时云端虚拟机和本地环境不一致。所以产生了两种思路 将云端虚拟机 做的尽量与 本地环境一样 无论本地还是云端，代码都跑在 约定的环境里 ==> docker 镜像的精髓 与《尽在双11》作者提到的 “docker 最重要的特质是docker

I have written the following basic Tuple template: template <typename... T> class Tuple; template <uintptr_t N, typename... T> struct TupleIndexer; template <typename Head, typename... Tail> class Tuple<Head, Tail...> : public Tuple<Tail...> { private: Head element; public: template <uintptr_t N> typename TupleIndexer<N, Head, Tail...>::Type& Get() { return TupleIndexer<N, Head, Tail...>::Get(*this); } uintptr_t GetCount() const { return sizeof...(Tail) + 1; } private: friend struct TupleIndexer<0, Head, Tail...>; }; template <> class Tuple<> { public: uintptr_t GetCount() const { return 0; }

I'm pretty new to java, and using netbeans for design a UI. What I am trying to do is... in the form. there are a jComboBox and a JTextField, where user can input the service he is choosing and an observation. So far so good. JComboBox is populated from database entries. The problem is, a user can input N different services at once (there are too much to be a bunch of checkboxes). I was thinking into add a "[+]" button (along with a "[-]" for removal). Thus, users click on [+] and another new line with a jcombobox + jtextfield appear right below the previous ones. I'm stucked at this point. On

When you run a .NET executable, what exactly takes place, step by step in order. My basic understanding is that you run the executable, the CLR does some checking, compiles the CIL it into platform specific code, loads it up along with the specified required dll's (as specified in the manifest(s)) and runs your program. Can someone elaborate on this, down to the "it allocates memory for this and that" level? I would really like to know what is happening from when you double-click on the executable to when your program is successfully running. P.S. diagrams, external links welcome. :-) There's

I've been looking up ways to run external programs using Java's runtime. This works fine, for instance: String[] cmd = {"mkdir", "test"}; Runtime.getRuntime().exec(cmd); Creates a new directory as you would expect. Now, from a bash window in Mac I can write this: love testgame To run the 'Love' game engine on a folder called testgame. Now, the reason this works is because I've aliased 'love' to call the love executable. I have a feeling that this is the reason that the following does not work: String[] cmd = {"love", "/Users/mtc06/testgame"}; Runtime.getRuntime().exec(cmd); And nor does this
