如何在生产中缩放Docker容器 [英] How to scale Docker containers in production

问题描述

所以我最近发现了这个很棒的工具，它说

So I recently discovered this awesome tool, and it says

Docker是一个开源项目，可轻松创建轻量级的
便携式，自给自足的容器从任何应用程序。开发人员在笔记本电脑上构建和测试的相同的
容器可以以
的规模生产，在虚拟机，裸机，OpenStack集群，public
云等上运行。

Docker is an open-source project to easily create lightweight, portable, self-sufficient containers from any application. The same container that a developer builds and tests on a laptop can run at scale, in production, on VMs, bare metal, OpenStack clusters, public clouds and more.

假设我有一个运行Nginx的Docker映像，一个网站连接到外部数据库。

Let's say I have a docker image which runs Nginx and a website connects to external database. How do I scale the container in production?

推荐答案

简而言之，你必须自己写逻辑来做这个。

The short answer is that you'd have to write your own logic to do this.

我希望这样的功能可以从建立在Docker之上的以下项目中脱颖而出，旨在支持生产中的应用程序：

I would expect this kind of feature to emerge from the following projects, built on top of docker, and designed to support applications in production:

• flynn


• deis


• coreos


• Mesos

• flynn
• deis
• coreos
• Mesos

亚马逊新的容器服务可以在集群中进行扩展。

严格来说， Flocker 不会扩展应用程序，而是设计用于在多个Docker主机之间移植的状态容器（运行数据库服务）的相关功能：

Strictly speaking Flocker does not "scale" applications, but it is designed to fufil a related function of making stateful containers (running databases services?) portable across multiple docker hosts:
