| 30 | +As Kubernetes develops and matures, features may be deprecated, removed, or replaced with better ones for the project's overall health. |
| 31 | +This article outlines some planned changes for the Kubernetes v1.31 release that the release team feels you should be aware of for the continued maintenance of your Kubernetes environment. |
| 32 | +The information listed below is based on the current status of the v1.31 release. |
| 33 | +It may change before the actual release date. |
| 34 | +--> |
| 35 | +随着 Kubernetes 的发展和成熟,为了项目的整体健康,某些特性可能会被弃用、删除或替换为更好的特性。 |
| 36 | +本文阐述了 Kubernetes v1.31 版本的一些更改计划,发行团队认为你应当了解这些更改, |
| 37 | +以便持续维护 Kubernetes 环境。 |
| 38 | +下面列出的信息基于 v1.31 版本的当前状态;这些状态可能会在实际发布日期之前发生变化。 |
| 39 | + |
| 40 | +<!-- |
| 41 | +## The Kubernetes API removal and deprecation process |
| 42 | +The Kubernetes project has a well-documented [deprecation policy](/docs/reference/using-api/deprecation-policy/) for features. |
| 43 | +This policy states that stable APIs may only be deprecated when a newer, stable version of that API is available and that APIs have a minimum lifetime for each stability level. |
| 44 | +A deprecated API has been marked for removal in a future Kubernetes release. |
| 45 | +It will continue to function until removal (at least one year from the deprecation), but usage will display a warning. |
| 46 | +Removed APIs are no longer available in the current version, so you must migrate to using the replacement. |
| 47 | +--> |
| 48 | +## Kubernetes API 删除和弃用流程 |
| 49 | + |
| 50 | +Kubernetes 项目针对其功能特性有一个详细说明的[弃用策略](/zh-cn/docs/reference/using-api/deprecation-policy/)。 |
| 51 | +此策略规定,只有当某稳定 API 的更新、稳定版本可用时,才可以弃用该 API,并且 API |
| 52 | +的各个稳定性级别都有对应的生命周期下限。 |
| 53 | +已弃用的 API 标记为在未来的 Kubernetes 版本中删除, |
| 54 | +这类 API 将继续发挥作用,直至被删除(从弃用起至少一年),但使用时会显示警告。 |
| 55 | +已删除的 API 在当前版本中不再可用,因此你必须将其迁移到替换版本。 |
| 56 | + |
| 57 | +<!-- |
| 58 | +* Generally available (GA) or stable API versions may be marked as deprecated but must not be removed within a major version of Kubernetes. |
| 59 | +
|
| 60 | +* Beta or pre-release API versions must be supported for 3 releases after the deprecation. |
| 61 | +
|
| 62 | +* Alpha or experimental API versions may be removed in any release without prior deprecation notice. |
| 63 | +--> |
| 64 | +* 正式发布的(GA)或稳定的 API 版本可被标记为已弃用,但不得在 Kubernetes 主要版本未变时删除。 |
| 65 | + |
| 66 | +* Beta 或预发布 API 版本在被弃用后,必须保持 3 个发布版本中仍然可用。 |
| 67 | + |
| 68 | +* Alpha 或实验性 API 版本可以在任何版本中删除,不必提前通知。 |
| 69 | + |
| 70 | +<!-- |
| 71 | +Whether an API is removed because a feature graduated from beta to stable or because that API did not succeed, all removals comply with this deprecation policy. |
| 72 | +Whenever an API is removed, migration options are communicated in the [documentation](/docs/reference/using-api/deprecation-guide/). |
| 73 | +--> |
| 74 | +无论 API 是因为某个特性从 Beta 版升级到稳定版,还是因为此 API 未成功而被删除,所有删除都将符合此弃用策略。 |
| 75 | +每当删除 API 时,迁移选项都会在[文档](/zh-cn/docs/reference/using-api/deprecation-guide/)中传达。 |
| 76 | + |
| 77 | +<!-- |
| 78 | +## A note about SHA-1 signature support |
| 79 | +
|
| 80 | +In [go1.18](https://go.dev/doc/go1.18#sha1) (released in March 2022), the crypto/x509 library started to reject certificates signed with a SHA-1 hash function. |
| 81 | +While SHA-1 is established to be unsafe and publicly trusted Certificate Authorities have not issued SHA-1 certificates since 2015, there might still be cases in the context of Kubernetes where user-provided certificates are signed using a SHA-1 hash function through private authorities with them being used for Aggregated API Servers or webhooks. |
| 82 | +If you have relied on SHA-1 based certificates, you must explicitly opt back into its support by setting `GODEBUG=x509sha1=1` in your environment. |
| 83 | +--> |
| 84 | +## 关于 SHA-1 签名支持的说明 |
| 85 | + |
| 86 | +在 [go1.18](https://go.dev/doc/go1.18#sha1)(2022 年 3 月发布)中,crypto/x509 |
| 87 | +库开始拒绝使用 SHA-1 哈希函数签名的证书。 |
| 88 | +虽然 SHA-1 被确定为不安全,并且公众信任的证书颁发机构自 2015 年以来就没有颁发过 SHA-1 证书, |
| 89 | +但在 Kubernetes 环境中,仍可能存在用户提供的证书通过私人颁发机构使用 SHA-1 哈希函数签名的情况, |
| 90 | +这些证书用于聚合 API 服务器或 Webhook。 |
| 91 | +如果你依赖基于 SHA-1 的证书,则必须通过在环境中设置 `GODEBUG=x509sha1=1` 以明确选择重新支持这种证书。 |
| 92 | + |
| 93 | +<!-- |
| 94 | +Given Go's [compatibility policy for GODEBUGs](https://go.dev/blog/compat), the `x509sha1` GODEBUG and the support for SHA-1 certificates will [fully go away in go1.24](https://tip.golang.org/doc/go1.23) which will be released in the first half of 2025. |
| 95 | +If you rely on SHA-1 certificates, please start moving off them. |
| 96 | +
|
| 97 | +Please see [Kubernetes issue #125689](https://github.com/kubernetes/kubernetes/issues/125689) to get a better idea of timelines around the support for SHA-1 going away, when Kubernetes releases plans to adopt go1.24, and for more details on how to detect usage of SHA-1 certificates via metrics and audit logging. |
| 98 | +--> |
| 99 | +鉴于 Go 的 [GODEBUG 兼容性策略](https://go.dev/blog/compat),`x509sha1` GODEBUG |
| 100 | +和对 SHA-1 证书的支持将 [在 2025 年上半年发布的 go1.24](https://tip.golang.org/doc/go1.23) |
| 101 | +中完全消失。 |
| 102 | +如果你依赖 SHA-1 证书,请开始放弃使用它们。 |
| 103 | + |
| 104 | +请参阅 [Kubernetes 问题 #125689](https://github.com/kubernetes/kubernetes/issues/125689), |
| 105 | +以更好地了解对 SHA-1 支持的时间表,以及 Kubernetes 发布采用 go1.24 |
| 106 | +的计划时间、如何通过指标和审计日志检测 SHA-1 证书使用情况的更多详细信息。 |

| 109 | +## Deprecations and removals in Kubernetes 1.31 |
| 110 | +
|
| 111 | +### Deprecation of `status.nodeInfo.kubeProxyVersion` field for Nodes ([KEP 4004](https://github.com/kubernetes/enhancements/issues/4004)) |
| 112 | +--> |
| 113 | +## Kubernetes 1.31 中的弃用和删除 |
| 114 | + |
| 115 | +### 弃用节点的 `status.nodeInfo.kubeProxyVersion` 字段([KEP 4004](https://github.com/kubernetes/enhancements/issues/4004)) |
| 116 | + |
| 117 | +<!-- |
| 118 | +The `.status.nodeInfo.kubeProxyVersion` field of Nodes is being deprecated in Kubernetes v1.31,and will be removed in a later release. |
| 119 | +It's being deprecated because the value of this field wasn't (and isn't) accurate. |
| 120 | +This field is set by the kubelet, which does not have reliable information about the kube-proxy version or whether kube-proxy is running. |
| 121 | +
|
| 122 | +The `DisableNodeKubeProxyVersion` [feature gate](/docs/reference/command-line-tools-reference/feature-gates/) will be set to `true` in by default in v1.31 and the kubelet will no longer attempt to set the `.status.kubeProxyVersion` field for its associated Node. |
| 123 | +--> |
| 124 | +Node 的 `.status.nodeInfo.kubeProxyVersion` 字段在 Kubernetes v1.31 中将被弃用, |
| 125 | +并将在后续版本中删除。该字段被弃用是因为其取值原来不准确,并且现在也不准确。 |
| 126 | +该字段由 kubelet 设置,而 kubelet 没有关于 kube-proxy 版本或 kube-proxy 是否正在运行的可靠信息。 |
| 127 | + |
| 128 | +在 v1.31 中,`DisableNodeKubeProxyVersion` |
| 129 | +[特性门控](/zh-cn/docs/reference/command-line-tools-reference/feature-gates/)将默认设置为 `true`, |
| 130 | +并且 kubelet 将不再尝试为其关联的 Node 设置 `.status.kubeProxyVersion` 字段。 |
| 131 | + |
| 132 | +<!-- |
| 133 | +### Removal of all in-tree integrations with cloud providers |
| 134 | +
|
| 135 | +As highlighted in a [previous article](/blog/2024/05/20/completing-cloud-provider-migration/), the last remaining in-tree support for cloud provider integration will be removed as part of the v1.31 release. |
| 136 | +This doesn't mean you can't integrate with a cloud provider, however you now **must** use the |
| 137 | +recommended approach using an external integration. Some integrations are part of the Kubernetes |
| 138 | +project and others are third party software. |
| 139 | +--> |
| 140 | +### 删除所有云驱动的树内集成组件 |
| 141 | + |
| 142 | +正如[之前一篇文章](/blog/2024/05/20/completing-cloud-provider-migration/)中所强调的, |
| 143 | +v1.31 版本将删除云驱动集成的树内支持的最后剩余部分。 |
| 144 | +这并不意味着你无法与某云驱动集成,只是你现在**必须**使用推荐的外部集成方法。 |
| 145 | +一些集成组件是 Kubernetes 项目的一部分,其余集成组件则是第三方软件。 |
| 146 | + |
| 147 | +<!-- |
| 148 | +This milestone marks the completion of the externalization process for all cloud providers' integrations from the Kubernetes core ([KEP-2395](https://github.com/kubernetes/enhancements/blob/master/keps/sig-cloud-provider/2395-removing-in-tree-cloud-providers/README.md)), a process started with Kubernetes v1.26. |
| 149 | +This change helps Kubernetes to get closer to being a truly vendor-neutral platform. |
| 150 | +
|
| 151 | +For further details on the cloud provider integrations, read our [v1.29 Cloud Provider Integrations feature blog](/blog/2023/12/14/cloud-provider-integration-changes/). |
| 152 | +For additional context about the in-tree code removal, we invite you to check the ([v1.29 deprecation blog](/blog/2023/11/16/kubernetes-1-29-upcoming-changes/#removal-of-in-tree-integrations-with-cloud-providers-kep-2395-https-kep-k8s-io-2395)). |
| 153 | +
|
| 154 | +The latter blog also contains useful information for users who need to migrate to version v1.29 and later. |
| 155 | +--> |
| 156 | +这一里程碑标志着将所有云驱动集成组件从 Kubernetes 核心外部化的过程已经完成 |
| 157 | +([KEP-2395](https://github.com/kubernetes/enhancements/blob/master/keps/sig-cloud-provider/2395-removing-in-tree-cloud-providers/README.md)), |
| 158 | +该过程从 Kubernetes v1.26 开始。 |
| 159 | +这一变化有助于 Kubernetes 进一步成为真正的供应商中立平台。 |
