+*节点合规性测试* 是一种容器化测试框架，为节点提供系统验证和功能测试。该测试验证节点是否满足 Kubernetes 的最低要求；通过测试的节点有资格加入 Kubernetes 集群。

+## 限制

+In Kubernetes version 1.5, node conformance test has the following limitations:

+* Node conformance test only supports Docker as the container runtime.

+在 Kubernetes 1.5 版中，节点合规性测试具有以下限制：
+
+* 节点合规性测试仅支持 Docker 作为容器运行时。
+
+<!--
+## Node Prerequisite
+-->
+## 节点先决条件
+
+<!--
+To run node conformance test, a node must satisfy the same prerequisites as a
+standard Kubernetes node. At a minimum, the node should have the following
+daemons installed:
+
+* Container Runtime (Docker)
+* Kubelet
+-->
+要运行节点合规性测试，节点必须满足与标准 Kubernetes 节点相同的先决条件。该节点至少应安装以下守护程序：
+
+* 容器运行时（Docker）
+* Kubelet
+
+<!--
+## Running Node Conformance Test
+-->
+## 运行节点合规性测试
+
+<!--
+To run the node conformance test, perform the following steps:
+
+1. Point your Kubelet to localhost `--api-servers="http://localhost:8080"`,
+because the test framework starts a local master to test Kubelet. There are some
+other Kubelet flags you may care:
+  * `--pod-cidr`: If you are using `kubenet`, you should specify an arbitrary CIDR to Kubelet, for example `--pod-cidr=10.180.0.0/24`.
+  * `--cloud-provider`: If you are using `--cloud-provider=gce`, you should
+    remove the flag to run the test.
+
+2. Run the node conformance test with command:
+
+```shell
+# $CONFIG_DIR is the pod manifest path of your Kubelet.
+# $LOG_DIR is the test output path.
+sudo docker run -it --rm --privileged --net=host \
+  -v /:/rootfs -v $CONFIG_DIR:$CONFIG_DIR -v $LOG_DIR:/var/result \
+  k8s.gcr.io/node-test:0.2
+```
+-->
+
+要运行节点合规性测试，请执行以下步骤：
+
+1. 将您的 Kubelet 指向 localhost `--api-servers="http://localhost:8080"`，因为测试框架启动了一个本地主服务器来测试 Kubelet。您可能会关注其他一些 Kubelet 标记：
+  * `--pod-cidr`： 如果你使用 `kubenet`，你应该为 Kubelet 指定一个任意的 CIDR，例如 `--pod-cidr=10.180.0.0/24`。
+  * `--cloud-provider`: 如果您使用`--cloud-provider = gce`，则应删除该标志以运行测试。
+
+2. 使用以下命令运行节点合规性测试：
+
+```shell
+# $CONFIG_DIR is the pod manifest path of your Kubelet.
+# $LOG_DIR is the test output path.
+sudo docker run -it --rm --privileged --net=host \
+  -v /:/rootfs -v $CONFIG_DIR:$CONFIG_DIR -v $LOG_DIR:/var/result \
+  k8s.gcr.io/node-test:0.2
+```
+
+<!--
+## Running Node Conformance Test for Other Architectures
+-->
+## 为其他架构运行节点合规性测试
+
+<!--
+Kubernetes also provides node conformance test docker images for other
+architectures:

+Kubernetes 还为其他架构提供节点合规性测试 docker 镜像：

+  Arch  |       Image       |

+ amd64  |  node-test-amd64  |
+  arm   |    node-test-arm  |
+ arm64  |  node-test-arm64  |

+## Running Selected Test

+## 运行选定的测试
+
+<!--
+To run specific tests, overwrite the environment variable `FOCUS` with the
+regular expression of tests you want to run.
+-->
+要运行特定测试，请使用要运行的测试的正则表达式覆盖环境变量 `FOCUS`。
+
+```shell
+sudo docker run -it --rm --privileged --net=host \
+  -v /:/rootfs:ro -v $CONFIG_DIR:$CONFIG_DIR -v $LOG_DIR:/var/result \
+  -e FOCUS=MirrorPod \ # Only run MirrorPod test
+  k8s.gcr.io/node-test:0.2
+```
+
+<!--
+To skip specific tests, overwrite the environment variable `SKIP` with the
+regular expression of tests you want to skip.
+-->
+要跳过特定测试，请使用要跳过的测试的正则表达式覆盖环境变量 `SKIP`。
+
+```shell
+sudo docker run -it --rm --privileged --net=host \
+  -v /:/rootfs:ro -v $CONFIG_DIR:$CONFIG_DIR -v $LOG_DIR:/var/result \
+  -e SKIP=MirrorPod \ # Run all conformance tests but skip MirrorPod test
+  k8s.gcr.io/node-test:0.2
+```

+Node conformance test is a containerized version of [node e2e test](https://github.com/kubernetes/community/blob/{{< param "githubbranch" >}}/contributors/devel/e2e-node-tests.md).By default, it runs all conformance tests.
+-->
+节点合规性测试是[节点e2e测试](https://github.com/kubernetes/community/blob/{{< param "githubbranch" >}}/contributors/devel/e2e-node-tests.md)的容器化版本。默认情况下，它会运行所有一致性测试。
+
+<!--
+Theoretically, you can run any node e2e test if you configure the container and
+mount required volumes properly. But **it is strongly recommended to only run conformance test**, because it requires much more complex configuration to run non-conformance test.
+-->
+从理论上讲，如果配置容器并正确安装所需的卷，则可以运行任何节点e2e测试。 但**强烈建议仅运行一致性测试**，因为它需要更复杂的配置来运行不一致性测试。
+
+<!--
+## Caveats
+-->
+## 注意事项
+
+<!--
+* The test leaves some docker images on the node, including the node conformance
+  test image and images of containers used in the functionality
+  test.
+* The test leaves dead containers on the node. These containers are created
+  during the functionality test.
+-->
+* 测试在节点上留下一些 docker 镜像，包括节点合规性测试图像和功能测试中使用的容器图像。
+* 测试在节点上留下了死容器。 这些容器是在功能测试期间创建的。
