何为金丝雀发布

金丝雀发布(Canary Release)是一种常见的软件发布策略,它涉及到将新代码或更新逐渐部署到一小部分用户或服务器(金丝雀),然后逐渐增加暴露的范围,直到所有用户或服务器都收到更新。

金丝雀发布主要有以下几个特点:

  1. 渐进部署: 金丝雀发布通过将新代码或更新逐渐部署到一小部分用户或服务器(金丝雀)来实现,从而降低了潜在的风险。如果新代码或更新存在问题,则只會影响到金丝雀用户或服务器,从而有助于早期发现并解决问题。
  2. 可控性: 金丝雀发布允许开发人员和运维人员对新代码或更新的部署有更多的控制。例如,他们可以设置金丝雀用户或服务器的比例,并在发现问题时暂停或回滚部署。
  3. 快速反馈: 金丝雀发布可以帮助开发人员和运维人员快速获得有关新代码或更新的反馈。通过监控金丝雀用户或服务器的性能和用户体验,开发人员和运维人员可以及时发现问题并采取措施来解决。
  4. 低风险: 金丝雀发布可以降低新代码或更新部署的风险。通过将新代码或更新逐渐部署到一小部分用户或服务器,开发人员和运维人员可以降低因新代码或更新导致严重问题的可能性。
