## Preserving the client source IP
|
||||
|
||||
Due to the implementation of this feature, the source IP seen in the target
|
||||
container will *not be the original source IP* of the client. To enable
|
||||
preservation of the client IP, the following fields can be configured in the
|
||||
service spec (supported in GCE/Google Kubernetes Engine environments):
|
||||
|
||||
* `service.spec.externalTrafficPolicy` - denotes if this Service desires to route
|
||||
external traffic to node-local or cluster-wide endpoints. There are two available
|
||||
options: "Cluster" (default) and "Local". "Cluster" obscures the client source
|
||||
IP and may cause a second hop to another node, but should have good overall
|
||||
load-spreading. "Local" preserves the client source IP and avoids a second hop
|
||||
for LoadBalancer and NodePort type services, but risks potentially imbalanced
|
||||
traffic spreading.
|
||||
* `service.spec.healthCheckNodePort` - specifies the healthcheck nodePort
|
||||
(numeric port number) for the service. If not specified, healthCheckNodePort is
|
||||
created by the service API backend with the allocated nodePort. It will use the
|
||||
user-specified nodePort value if specified by the client. It only has an
|
||||
effect when type is set to "LoadBalancer" and externalTrafficPolicy is set
|
||||
to "Local".
|
||||
|
||||
This feature can be activated by setting `externalTrafficPolicy` to "Local" in the
|
||||
Service Configuration file.

|
||||
* `service.spec.healthCheckNodePort` - 指定服务的 healthcheck nodePort（数字端口号）。如果未指定，则 serviceCheckNodePort 由服务 API 后端使用已分配的 nodePort 创建。如果客户端指定，它将使用客户端指定的 nodePort 值。仅当 type 设置为 "LoadBalancer" 并且 externalTrafficPolicy 设置为 "Local" 时才生效。

Below you could find the deprecated Beta annotations used to enable this feature
|

prior to its stable version. Newer Kubernetes versions may stop supporting these
|
||||
after v1.7. Please update existing applications to use the fields directly.
|
||||
|
||||
* `service.beta.kubernetes.io/external-traffic` annotation <-> `service.spec.externalTrafficPolicy` field
|
||||
* `service.beta.kubernetes.io/healthcheck-nodeport` annotation <-> `service.spec.healthCheckNodePort` field
|
||||
|
||||
`service.beta.kubernetes.io/external-traffic` annotation has a different set of values
|
||||
compared to the `service.spec.externalTrafficPolicy` field. The values match as follows:
|
||||
|
||||
* "OnlyLocal" for annotation <-> "Local" for field
|
||||
* "Global" for annotation <-> "Cluster" for field

您可以在下面找到已弃用的 Beta annotation，在稳定版本前使用它来使用该功能。较新的 Kubernetes 版本可能会在 v1.7 之后停止支持这些功能。
|
||||
请更新现有应用程序以直接使用这些字段。
|
||||
|
||||
* `service.beta.kubernetes.io/external-traffic` annotation <-> `service.spec.externalTrafficPolicy` 字段
|
||||
* `service.beta.kubernetes.io/healthcheck-nodeport` annotation <-> `service.spec.healthCheckNodePort` 字段
|
||||
|
||||
`service.beta.kubernetes.io/external-traffic` annotation 与 `service.spec.externalTrafficPolicy` 字段相比拥有一组不同的值。值匹配如下：
|
||||
|
||||
* "OnlyLocal" annotation <-> "Local" 字段
|
||||
* "Global" annotation <-> "Cluster" 字段
|
||||
|

**请注意，此功能目前尚未实现在所有云提供商/环境中。**

## 垃圾收集负载均衡器

Known issues:
|
||||
In usual case, the correlating load balancer resources in cloud provider should
|
||||
be cleaned up soon after a LoadBalancer type Service is deleted. But it is known
|
||||
that there are various corner cases where cloud resources are orphaned after the
|
||||
associated Service is deleted. Finalizer Protection for Service LoadBalancers was
|
||||
introduced to prevent this from happening. By using finalizers, a Service resource
|
||||
will never be deleted until the correlating load balancer resources are also deleted.
|
||||
-->
|
||||
已知的问题：
|
||||
在通常情况下，应在删除 LoadBalancer 类型服务后立即清除云提供商中的相关负载均衡器资源。但是，众所周知，在删除关联的服务后，云资源被孤立的情况很多。引入了针对服务负载均衡器的终结器保护，以防止这种情况发生。通过使用终结器，在删除相关的负载均衡器资源之前，也不会删除服务资源。

<!--
|
||||
Specifically, if a Service has `type` LoadBalancer, the service controller will attach
|
||||
a finalizer named `service.kubernetes.io/load-balancer-cleanup`.
|
||||
The finalizer will only be removed after the load balancer resource is cleaned up.
|
||||
This prevents dangling load balancer resources even in corner cases such as the
|
||||
service controller crashing.
|
||||
-->
|
||||
具体来说，如果服务具有 `type` LoadBalancer，则服务控制器将附加一个名为 `service.kubernetes.io/load-balancer-cleanup` 的终结器。
|
||||
仅在清除负载均衡器资源后才能删除终结器。
|
||||
即使在诸如服务控制器崩溃之类的极端情况下，这也可以防止负载均衡器资源悬空。

## External Load Balancer Providers
|
||||
|
||||
It is important to note that the datapath for this functionality is provided by a load balancer external to the Kubernetes cluster.
|
||||
|
||||
When the service type is set to `LoadBalancer`, Kubernetes provides functionality equivalent to `type=<ClusterIP>` to pods within the cluster and extends it by programming the (external to Kubernetes) load balancer with entries for the Kubernetes pods. The Kubernetes service controller automates the creation of the external load balancer, health checks (if needed), firewall rules (if needed) and retrieves the external IP allocated by the cloud provider and populates it in the service object.

## 外部负载均衡器提供商

<!--

|
||||
-->
|
||||
请务必注意，此功能的数据路径由 Kubernetes 集群外部的负载均衡器提供。
|
||||
|
||||
当服务类型设置为 `LoadBalancer` 时，Kubernetes 向集群中的 pod 提供与 `type=<ClusterIP>` 等效的功能，并通过使用 Kubernetes pod 的条目对负载均衡器（从外部到 Kubernetes）进行编程来扩展它。 Kubernetes 服务控制器自动创建外部负载均衡器，健康检查（如果需要），防火墙规则（如果需要），并获取云提供商分配的外部 IP 并将其填充到服务对象中。

## Caveats and Limitations when preserving source IPs
|
||||
|
||||
GCE/AWS load balancers do not provide weights for their target pools. This was not an issue with the old LB
|
||||
kube-proxy rules which would correctly balance across all endpoints.
|
||||
|
||||
With the new functionality, the external traffic will not be equally load balanced across pods, but rather
|
||||
equally balanced at the node level (because GCE/AWS and other external LB implementations do not have the ability
|
||||
for specifying the weight per node, they balance equally across all target nodes, disregarding the number of
|
||||
pods on each node).
|
||||
|
||||
We can, however, state that for NumServicePods << NumNodes or NumServicePods >> NumNodes, a fairly close-to-equal
|
||||
distribution will be seen, even without weights.
|
||||
|
||||
Once the external load balancers provide weights, this functionality can be added to the LB programming path.
|
||||
*Future Work: No support for weights is provided for the 1.4 release, but may be added at a future date*
|
||||
|
||||
Internal pod to pod traffic should behave similar to ClusterIP services, with equal probability across all pods.
|
||||
-->
|
||||
## 保留源 IP 时的注意事项和限制
|
||||
|
||||
GCE/AWS 负载均衡器不为其目标池提供权重。对于旧的 LB kube-proxy 规则来说，这不是一个问题，它可以在所有端点之间正确平衡。
|
||||
|
||||
<!--
|
||||

||||
for specifying the weight per node, they balance equally across all target nodes, disregarding the number of
|
||||
pods on each node).
|
||||
-->
|
||||
使用新功能，外部流量不会在 pod 之间平均负载，而是在节点级别平均负载（因为 GCE/AWS 和其他外部 LB 实现无法指定每个节点的权重，因此它们的平衡跨所有目标节点，并忽略每个节点上的 pod 数量）。
|
||||
|
||||
<!--
|
||||

|
||||
distribution will be seen, even without weights.
|
||||
-->
|
||||
但是，我们可以声明，对于 NumServicePods << NumNodes 或 NumServicePods >> NumNodes 时，即使没有权重，也会看到接近相等的分布。
|
||||
|
||||

|
||||
-->
|
||||
一旦外部负载平衡器提供权重，就可以将此功能添加到 LB 编程路径中。
|
||||
*未来工作：1.4 版本不提供权重支持，但可能会在将来版本中添加*
|
||||
|
||||
内部 pod 到 pod 的流量应该与 ClusterIP 服务类似，所有 pod 的概率相同。
