如何将我的Spray API部署到生产中？

问题描述

我正在考虑将经过本地测试的剩余api部署到云中的过程应该如何，可以说像亚马逊这样的基础设施即服务（而不是像Heroku这样的平台即服务）。

I'm thinking about how should be the process to deploy my already locally tested rest api to the cloud, lets say an infrastructure as a service (not a platform as a service such as Heroku) like amazon.

我已经设置并运行了sbt，但我的问题是我应该如何在生产环境中部署它？

I have my local envorinment set up with sbt up and running but my question is How should I deploy this in a production environment?

定义一个进程，让devops从git repo中提取最新更改，然后简单地执行sbt run是明智的吗？

Is it sane to define a process in which the devops pulls the most recent changes from the git repo and then simply executes sbt run?

我想知道如何使用scala + spray + sbt的团队将其api部署到生产环境。

I want to know how does the teams that uses scala+spray+sbt deploys their apis to a production environment.

推荐答案

我们服务的核心是scala + Akka +喷雾剂+ Mongo。因此，我们使用GitHub进行版本控制。将已检查的PR合并到master分支后，Jenkins自动测试n的builds项目。如果所有测试都成功，那么Jenking将运行几个脚本：

The heart of our services is scala + akka + spray + mongo. So we are using GitHub for version control. After merging checked PRs to the master branch, Jenkins automaticaly tests'n'builds project. If all tests were successful then Jenking runs a couple of scripts:

1. 递增项目版本（当前以shell编写，但将更改为sbt ）


2. 使用
$ b $运行组装任务b
3. 运行部署脚本（用Fabric与Python一起编写），将我们的jar部署到EC2

基本步骤已完成几个选择：

Basicaly on the thrid step you have a couple of choices:

使用IO / Spray引导文件制作可运行的jar：

object Boot extends App {
  implicit val system = ActorSystem("ServiceName")
  val log = system.log
  val service = system.actorOf(Props[Service], name="serviceActor")
  IO(Http) ! Http.Bind(service, interface = host, port = port)
}

将可运行的jar用作Akka的微内核：

在这种情况下，您应该扩展Bootable特质并覆盖 startup 和关机方法：

In this case you should extend Bootable trait and override startup and shutdown methods:

class Kernel extends Bootable {
  // many lines of code
  def startup() {
    scheduler.start()
    SomeActorSystem.startup()
  }

  def shutdown() {
    scheduler.shutdown()
    SomeActorSystem.shutdown()
    system.shutdown()
  }
}

使用TypeSafe起始脚本：

无法显示一个例子，但是它对 =）

Can't show an example, but it has a good intro on github =)

我们在不同情况下都使用了这种方式。

We are using all of this way in different cases.
