通过管道进行部署和发布
发布功能
上一节介绍了代码部署的几种机制和策略。但是，正如我们之前所说，这只是持续交付
的一个方面。你现在能够不断地将新的变更部署到生产环境，但并不意味着应该将这些
变更暴露给用户。用户更喜欢稳定、可预知的体验，他们只能容忍有限的变化。另一方面，
某些变更只有与其他变更配合起来才有意义，但是你不会想一次部署所有的变更，因为
这样的风险太大。你需要另一种部署机制，可以控制向用户公开哪些功能。
另一方面，你要记得不只是向用户提供功能。在微服务领域，服务之间多以
RESTful
API
的形式调用，有时为了启用新的功能，你可能需要改动这些
API
，但是在这种情况
下你需要深思熟虑，因为修改
API
可能会影响到一些客户端应用程序，反过来又会对后
端服务产生级联影响。
因此，你必须有一套独立于服务部署以外的手段，可以控制变更对其他服务的影响，这
样你就可以与负责服务的团队或者企业进行沟通，做出恰当的安排。这就是我们将在本
节中介绍的内容。
服务网格 ：发布功能的未来？
自
2016
年年底以来，人们开始越来越关注服务网格，这是一个专用的基础设施层，
用来让服务与服务之间的通信变得可靠、安全以及快速。这个领域出现了很多开
源项目和商业产品，例如
Linkerd
、
Envoy/Istio
、
Cilium
和
Consul Connect
。在
我们编写本书时，人们仍然围绕服务网格在进行很多尝试，因此我们不会在此提
供相关的指导。但是，我们建议你了解这个有趣的领域，特别是如果你正在使用
容器来运行应用程序。这个领域的思想领袖也对 ...
