1.在本机启动单机版k8s

2.看一下是否运行成功
/home/opama/workspace/k8s/src/k8s.io/kubernetes/_output/local/bin# mkdir /home/opama/kube-release /home/opama/workspace/k8s/src/k8s.io/kubernetes/_output/local/bin# mv linux /home/opama/kube-release/ /home/opama/kube-release/linux/amd64# cp -p kubectl /bin/ /home/opama/kube-release/linux/amd64# kubectl get node

创建config文件
vim /root/.kube/config { "User": "root", "Password": "" }
本机运行Conformance的e2e用例
/home/opama/workspace/k8s/src/k8s.io/kubernetes# KUBERNETES_PROVIDER=local go run hack/e2e.go -v -test --test_args="--host=http://127.0.0.1:8080 --ginkgo.focus=[Conformance] --ginkgo.skip=[Serial]"

注意的是，很多默认的gcr.io镜像是下载不下来的，所以会出错，还是需要去改的
运行自己的用例如把ReplicasSet复制重命名为ReplicaSetMali保存在rs_mali.go
export KUBERNETES_PROVIDER="local" export KUBE_MASTER_IP="127.0.0.1:8080" export KUBE_MASTER="opama-HP-EliteBook-8560w"
执行
go run hack/e2e.go -v -test --test_args="--host=http://127.0.0.1:8080 --ginkgo.focus=ReplicaSetMali"
修改后重新编译e2e
go install ./test/e2e make WHAT=test/e2e/e2e.test
会遇到一些错误，如解析版本号失败：
?

如取到的podname含特殊字符：

修改了函数的实现
err = wait.Poll(retryInterval, retryTimeout, framework.PodProxyResponseChecker(f.Client, f.Namespace.Name, label, name, true, pods).CheckAllResponses)
最后运行成功
