+<!--Ensuring the reliability of SIG Node upstream code is a continuous effort
+that takes a lot of behind-the-scenes effort from many contributors.
+There are frequent releases of Kubernetes, base operating systems,
+container runtimes, and test infrastructure that result in a complex matrix that
+requires attention and steady investment to "keep the lights on."
+In May 2020, the Kubernetes node special interest group ("SIG Node") organized a new
+subproject for continuous integration (CI) for node-related code and tests. Since its
+inauguration, the SIG Node CI subproject has run a weekly meeting, and even the full hour
+is often not enough to complete triage of all bugs, test-related PRs and issues, and discuss all
+related ongoing work within the subgroup.-->
+保证 SIG 节点上游代码的可靠性是一项持续的工作，需要许多贡献者在幕后付出大量努力。
+Kubernetes、基础操作系统、容器运行时和测试基础架构的频繁发布，导致了一个复杂的矩阵，
+需要关注和稳定的投资来“保持灯火通明”。2020 年 5 月，Kubernetes Node 特殊兴趣小组
+（“SIG Node”）为节点相关代码和测试组织了一个新的持续集成（CI）子项目。自成立以来，SIG Node CI
+子项目每周举行一次会议，即使一整个小时通常也不足以完成对所有缺陷、测试相关的 PR 和问题的分类，
+并讨论组内所有相关的正在进行的工作。
+
+<!--Over the past two years, we've fixed merge-blocking and release-blocking tests, reducing time to merge Kubernetes contributors' pull requests thanks to reduced test flakes. When we started, Node test jobs only passed 42% of the time, and through our efforts, we now ensure a consistent >90% job pass rate. We've closed 144 test failure issues and merged 176 pull requests just in kubernetes/kubernetes. And we've helped subproject participants ascend the Kubernetes contributor ladder, with 3 new org members, 6 new reviewers, and 2 new approvers.-->
+在过去两年中，我们修复了阻塞合并和阻塞发布的测试，由于减少了测试缺陷，缩短了合并 Kubernetes 
+贡献者的拉取请求的时间。通过我们的努力，任务通过率由开始时 42% 提高至稳定大于 90% 。我们已经解决了 144 个测试失败问题，
+并在 kubernetes/kubernetes 中合并了 176 个拉取请求。
+我们还帮助子项目参与者提升了 Kubernetes 贡献者的等级，新增了 3 名组织成员、6 名评审员和 2 名审批员。
+
+
+<!--The Node CI subproject is an approachable first stop to help new contributors
+get started with SIG Node. There is a low barrier to entry for new contributors
+to address high-impact bugs and test fixes, although there is a long
+road before contributors can climb the entire contributor ladder:
+it took over a year to establish two new approvers for the group.
+The complexity of all the different components that power Kubernetes nodes
+and its test infrastructure requires a sustained investment over a long period
+for developers to deeply understand the entire system,
+both at high and low levels of detail.-->
+Node CI 子项目是一个可入门的第一站，帮助新参与者开始使用 SIG Node。对于新贡献者来说，
+解决影响较大的缺陷和测试修复的门槛很低，尽管贡献者要攀登整个贡献者阶梯还有很长的路要走：
+为该团队培养了两个新的审批人花了一年多的时间。为 Kubernetes 节点及其测试基础设施提供动力的所有
+不同组件的复杂性要求开发人员在很长一段时间内进行持续投资，
+以深入了解整个系统，从宏观到微观。
+
+<!--We have several regular contributors at our meetings, however; our reviewers
+and approvers pool is still small. It is our goal to continue to grow
+contributors to ensure a sustainable distribution of work
+that does not just fall to a few key approvers.-->
+虽然在我们的会议上有几个比较固定的贡献者；但是我们的评审员和审批员仍然很少。
+我们的目标是继续增加贡献者，以确保工作的可持续分配，而不仅仅是少数关键批准者。
+
+<!--It's not always obvious how subprojects within SIGs are formed, operate,
+and work. Each is unique to its sponsoring SIG and tailored to the projects
+that the group is intended to support. As a group that has welcomed many
+first-time SIG Node contributors, we'd like to share some of the details and
+accomplishments over the past two years,
+helping to demystify our inner workings and celebrate the hard work
+of all our dedicated contributors!-->
+SIG 中的子项目如何形成、运行和工作并不总是显而易见的。每一个都是其背后的 SIG 所独有的，
+并根据该小组打算支持的项目量身定制。作为一个欢迎了许多第一次 SIG Node 贡献者的团队，
+我们想分享过去两年的一些细节和成就，帮助揭开我们内部工作的神秘面纱，并庆祝我们所有专注贡献者的辛勤工作！

+signed up, to improve SIG Node CI signal and overall observability.
+Victor Pickard focused on getting
+[testgrid jobs](https://testgrid.k8s.io/sig-node) passing
+when Ning Liao suggested forming a group around this effort and came up with
+the [original group charter document](https://docs.google.com/document/d/1yS-XoUl6GjZdjrwxInEZVHhxxLXlTIX2CeWOARmD8tY/edit#heading=h.te6sgum6s8uf).

+Sergey Kanzhelev joined Victor shortly after as a co-lead.-->
+***2020 年 5 月*** SIG Node CI 组于 2020 年 5 月 11 日成立，超过

+注册，以改进 SIG Node CI 信号和整体可观测性。
+Victor Pickard 专注于让 [testgrid 可以运行](https://testgrid.k8s.io/sig-node) ，
+当时 Ning Liao 建议围绕这项工作组建一个小组，并提出 
+[最初的小组章程文件](https://docs.google.com/document/d/1yS-XoUl6GjZdjrwxInEZVHhxxLXlTIX2CeWOARmD8tY/edit#heading=h.te6sgum6s8uf) 。
+SIG Node 赞助成立以 Victor 作为子项目负责人的小组。Sergey Kanzhelev 不久后就加入 Victor，担任联合领导人。
+
+<!--At the kick-off meeting, we discussed which tests to concentrate on fixing first
+and discussed merge-blocking and release-blocking tests, many of which were failing due
+to infrastructure issues or buggy test code.-->
+在启动会议上，我们讨论了应该首先集中精力修复哪些测试，并讨论了阻塞合并和阻塞发布的测试，
+其中许多测试由于基础设施问题或错误的测试代码而失败。
+
+<!--The subproject launched weekly hour-long meetings to discuss ongoing work
+discussion and triage.-->

+子项目负责人 Elana Hashman 和 Sergey Kanzhelev 都被认为是所有节点测试代码的审批人，由 SIG node 和 SIG Testing 支持。
+

+fixed and the job was passing without flakes.-->
+最终节点系列测试已完全修复。系列测试由许多中断性和缓慢的测试组成，这些测试往往是碎片化的，很难排除故障。

+a high-quality release, in part due to our efforts in identifying
+and fixing flakes in Node and beyond.-->
+1.23 版本在测试质量和 CI 信号方面得到了特别的关注。SIG Node CI 子项目很自豪能够为这样一个高质量的发布做出贡献，
+部分原因是我们在识别和修复节点内外的碎片方面所做的努力。

+
+<!--Dockershim code was removed from Kubernetes. This affected nearly half of SIG Node's
+test jobs and the SIG Node CI subproject reacted quickly and retargeted all the
+tests. SIG Node was the first SIG to complete test migrations off dockershim,
+providing examples for other affected SIGs. The vast majority of new jobs passed
+at the time of introduction without further fixes required. The [effort of
+removing dockershim](https://k8s.io/dockershim)) from Kubernetes is ongoing.
+There are still some wrinkles from the dockershim removal as we uncover more
+dependencies on dockershim, but we plan to stabilize all test jobs
+by the 1.24 release.-->
+Dockershim 代码已从 Kubernetes 中删除。这影响了 SIG Node 近一半的测试作业，
+SIG Node CI 子项目反应迅速，并重新确定了所有测试的目标。
+SIG Node 是第一个完成 dockershim 外测试迁移的 SIG ，为其他受影响的 SIG 提供了示例。
+绝大多数新工作在引入时都已通过，无需进一步修复。
+从 Kubernetes 中[将 dockershim 除名的工作](https://k8s.io/dockershim) 正在进行中。
+随着我们发现 dockershim 对 dockershim 的依赖性越来越大，dockershim 的删除仍然存在一些问题，
+但我们计划在 1.24 版本之前确保所有测试任务稳定。
