-A zone represents a logical failure domain.  It is common for Kubernetes clusters to span multiple zones for increased availability.  While the exact definition of a zone is left to infrastructure implementations, common properties of a zone include very low network latency within a zone, no-cost network traffic within a zone, and failure independence from other zones.  For example, nodes within a zone might share a network switch, but nodes in different zones should not.
--->
-区域代表逻辑故障域。Kubernetes 集群通常跨越多个区域以提高可用性。
-虽然区域的确切定义留给基础架构实现，但是区域的常见属性包括区域内的网络延迟非常低，区域内的免费网络流量以及与其他区域的故障独立性。
-例如，一个区域内的节点可能共享一个网络交换机，但不同区域内的节点则不应共享。
-
-<!--
-A region represents a larger domain, made up of one or more zones.  It is uncommon for Kubernetes clusters to span multiple regions,  While the exact definition of a zone or region is left to infrastructure implementations, common properties of a region include higher network latency between them than within them, non-zero cost for network traffic between them, and failure independence from other zones or regions.  For example, nodes within a region might share power infrastructure (e.g. a UPS or generator), but nodes in different regions typically would not.
--->
-地区代表一个更大的域，由一个或多个区域组成。
-Kubernetes 集群跨越多个地域是不常见的，而地域或区域的确切定义则留给基础设施实现，
-地域的共同属性包括它们之间的网络延迟比它们内部更高，它们之间的网络流量成本不为零，故障独立于其他区域或域。
-例如，一个地域内的节点可能共享电力基础设施（例如 UPS 或发电机），但不同地域的节点通常不会共享。
-
-<!--
-Kubernetes makes a few assumptions about the structure of zones and regions:
-1) regions and zones are hierarchical: zones are strict subsets of regions and no zone can be in 2 regions
-2) zone names are unique across regions; for example region "africa-east-1" might be comprised of zones "africa-east-1a" and "africa-east-1b"
--->
-Kubernetes 对区域和区域的结构做了一些假设:
-1) 地域和区域是分层的:区域是地域的严格子集，任何区域都不能位于两个地域中。
-2) 区域名称在地域之间是唯一的；例如，地域 “africa-east-1” 可能包含区域 “africa-east-1a” 和 “africa-east-1b”。
-
-<!--
-It should be safe to assume that topology labels do not change. 
-Even though labels are strictly mutable,
- consumers of them can assume that a given node is not going to be moved between zones without being destroyed and recreated.
--->
-标签的使用者可以安全地假设拓扑标签不变。
-即使标签是严格可变的，标签的使用者也可以认为节点只能通过被销毁并重建才能从一个区域迁移到另一个区域。
-
-<!--
-Kubernetes can use this information in various ways.
-For example,
-the scheduler automatically tries to spread the Pods in a ReplicaSet across nodes in a single-zone cluster (to reduce the impact of node failures,
-see [kubernetes.io/hostname](#kubernetesiohostname)). With multiple-zone clusters, this spreading behavior also applies to zones (to reduce the impact of zone failures).
-This is achieved via _SelectorSpreadPriority_.
--->
-Kubernetes 可以以各种方式使用这些信息。
-例如，调度器自动尝试将 ReplicaSet 中的多个 Pods 分布到单区域集群中的多个节点上（为了减少节点故障的影响，
-请参阅 [kubernetesiohostname](#kubernetesiohostname)）。
-对于多区域集群，这种分布行为也被应用到区域上（以减少区域故障的影响）。
-这是通过 _SelectorSpreadPriority_ 实现的。
-
-<!--
-_SelectorSpreadPriority_ is a best effort placement.
- If the zones in your cluster are heterogeneous (for example: different numbers of nodes, different types of nodes, or different pod resource requirements),
- this placement might prevent equal spreading of your Pods across zones.
- If desired, you can use homogenous zones (same number and types of nodes) to reduce the probability of unequal spreading.
--->
-_SelectorSpreadPriority_ 是一种尽力而为（best-effort）的处理方式，如果集群中的区域是异构的 
-(例如：不同区域之间的节点数量、节点类型或 Pod 资源需求不同），可能使得 Pod 在各区域间无法均匀分布。
-如有需要，用户可以使用同质的区域(节点数量和类型相同) 来减小 Pod 分布不均的可能性。
-
-<!--
-The scheduler (through the _VolumeZonePredicate_ predicate) also will ensure that Pods, that claim a given volume, are only placed into the same zone as that volume. Volumes cannot be attached across zones.
--->
-由于卷不能跨区域挂载（Attach），调度器（通过 _VolumeZonePredicate_ 预选）也会保证需要特定卷的 Pod 被调度到卷所在的区域中。
-
-<!--
-If `PersistentVolumeLabel` does not support automatic labeling of your PersistentVolumes, you should consider
-adding the labels manually (or adding support for `PersistentVolumeLabel`). With `PersistentVolumeLabel`,
-the scheduler prevents Pods from mounting volumes in a different zone.
-If your infrastructure doesn't have this constraint, you don't need to add the zone labels to the volumes at all.
--->
-如果 `PersistentVolumeLabel` 准入控制器不支持自动为 PersistentVolume 打标签，且用户希望防止 pod 跨区域进行卷的挂载，
-应考虑手动打标签 (或增加对 `PersistentVolumeLabel` 的支持）。如果用户的基础设施没有这种约束，则不需要为卷添加区域标签。

+## alpha.kubernetes.io/provided-node-ip
+
+示例：`alpha.kubernetes.io/provided-node-ip: "10.0.0.1"`
+
+用于：Node
+
+<!-- 
+The kubelet can set this annotation on a Node to denote its configured IPv4 address.
+
+When kubelet is started with the "external" cloud provider, it sets this annotation on the Node to denote an IP address set from the command line flag (`--node-ip`). This IP is verified with the cloud provider as valid by the cloud-controller-manager.
+
+**The taints listed below are always used on Nodes**
+-->
+kubectl 在 Node 上设置此注解，表示它的 IPv4 地址。
+
+当 kubectl 由外部的云供应商启动时，在 Node 上设置此注解，表示由命令行标记(`--node-ip`)设置的 IP 地址。
+cloud-controller-manager 向云供应商验证此 IP 是否有效。
+
+**以下列出的污点只能用于 Node**
+
+## node.kubernetes.io/not-ready
+
+示例：`node.kubernetes.io/not-ready:NoExecute`
+
+<!-- 
+The node controller detects whether a node is ready by monitoring its health and adds or removes this taint accordingly.
+-->
+节点控制器通过健康监控来检测节点是否就绪，并据此添加/删除此污点。
+
+## node.kubernetes.io/unreachable
+
+示例：`node.kubernetes.io/unreachable:NoExecute`
+
+<!-- 
+The node controller adds the taint to a node corresponding to the [NodeCondition](/docs/concepts/architecture/nodes/#condition) `Ready` being `Unknown`.
+-->
+如果 [NodeCondition](/docs/concepts/architecture/nodes/#condition) 的 `Ready` 键值为 `Unknown`，节点控制器将添加污点到 node。
+
+## node.kubernetes.io/unschedulable
+
+示例：`node.kubernetes.io/unschedulable:NoSchedule`
+
+<!-- 
+The taint will be added to a node when initializing the node to avoid race condition.
+-->
+当初始化节点时，添加此污点，来避免竟态的发生。
+
+## node.kubernetes.io/memory-pressure
+
+示例：`node.kubernetes.io/memory-pressure:NoSchedule`
+
+<!-- 
+The kubelet detects memory pressure based on `memory.available` and `allocatableMemory.available` observed on a Node. The observed values are then compared to the corresponding thresholds that can be set on the kubelet to determine if the Node condition and taint should be added/removed.
+-->
+kubelet 依据节点上观测到的 `memory.available` 和 `allocatableMemory.available` 来检测内存压力。
+用观测值对比 kubelet 设置的阈值，以判断节点状态和污点是否可以被添加/移除。
+
+## node.kubernetes.io/disk-pressure
+
+示例：`node.kubernetes.io/disk-pressure:NoSchedule`
+
+<!-- 
+The kubelet detects disk pressure based on `imagefs.available`, `imagefs.inodesFree`, `nodefs.available` and `nodefs.inodesFree`(Linux only) observed on a Node. The observed values are then compared to the corresponding thresholds that can be set on the kubelet to determine if the Node condition and taint should be added/removed.
+-->
+kubelet 依据节点上观测到的 `imagefs.available`、`imagefs.inodesFree`、`nodefs.available` 和 `nodefs.inodesFree`(仅 Linux) 来判断磁盘压力。 
+用观测值对比 kubelet 设置的阈值，以确定节点状态和污点是否可以被添加/移除。
+
+## node.kubernetes.io/network-unavailable
+
+示例：`node.kubernetes.io/network-unavailable:NoSchedule`
+
+<!-- 
+This is initially set by the kubelet when the cloud provider used indicates a requirement for additional network configuration. Only when the route on the cloud is configured properly will the taint be removed by the cloud provider.
+-->
+它初始由 kubectl 设置，云供应商用它来指示对额外网络配置的需求。
+仅当云中的路由器配置妥当后，云供应商才会移除此污点。
+
+## node.kubernetes.io/pid-pressure
+
+示例：`node.kubernetes.io/pid-pressure:NoSchedule`
+
+<!-- 
+The kubelet checks D-value of the size of `/proc/sys/kernel/pid_max` and the PIDs consumed by Kubernetes on a node to get the number of available PIDs that referred to as the `pid.available` metric. The metric is then compared to the corresponding threshold that can be set on the kubelet to determine if the node condition and taint should be added/removed.
+-->
+kubelet 检查 `/proc/sys/kernel/pid_max` 尺寸的 D 值（D-value），以及节点上 Kubernetes 消耗掉的 PID，以获取可用的 PID 数量，此数量可通过指标 `pid.available` 得到。
+然后用此指标对比 kubelet 设置的阈值，以确定节点状态和污点是否可以被添加/移除。
+
+## node.cloudprovider.kubernetes.io/uninitialized
+
+示例：`node.cloudprovider.kubernetes.io/uninitialized:NoSchedule`
+
+<!-- 
+Sets this taint on a node to mark it as unusable, when kubelet is started with the "external" cloud provider, until a controller from the cloud-controller-manager initializes this node, and then removes the taint.
+-->
+当 kubelet 由外部云供应商启动时，在节点上设置此污点以标记节点不可用，直到一个 cloud-controller-manager 控制器初始化此节点之后，才会移除此污点。
+
+## node.cloudprovider.kubernetes.io/shutdown
+
+示例：`node.cloudprovider.kubernetes.io/shutdown:NoSchedule`
+
+<!-- 
+If a Node is in a cloud provider specified shutdown state, the Node gets tainted accordingly with `node.cloudprovider.kubernetes.io/shutdown` and the taint effect of `NoSchedule`.
+-->
+如果一个云供应商的节点被指定为关机状态，节点被打上污点 `node.cloudprovider.kubernetes.io/shutdown`，污点的影响为 `NoSchedule`。
