单机运行k8s以及e2e
1.在本机启动单机版k8s
/home/opama/workspace/k8s/src/k8s.io/kubernetes# hack/local-up-cluster.sh

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
NAME STATUS AGE 127.0.0.1 Ready 11m
3.本机运行下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="Secrets"'

发现是版本不符合，手动指定kubectl，中间还会遇到node数目检查，我直接修改e2e.go中的minNodeCount=1了
/home/opama/workspace/k8s/src/k8s.io/kubernetes# export KUBECTL_PATH=/bin/kubectl /home/opama/workspace/k8s/src/k8s.io/kubernetes# cluster/kubectl.sh version Client Version: version.Info{Major:"1", Minor:"3", GitVersion:"v1.3.1.1+9ec21ad3522752", GitCommit:"9ec21ad3522752415c2f82db9f6aa1117dbe583d", GitTreeState:"clean", BuildDate:"2016-10-04T13:39:33Z", GoVersion:"go1.6.2", Compiler:"gc", Platform:"linux/amd64"} Server Version: version.Info{Major:"1", Minor:"3", GitVersion:"v1.3.1.1+9ec21ad3522752", GitCommit:"9ec21ad3522752415c2f82db9f6aa1117dbe583d", GitTreeState:"clean", BuildDate:"2016-10-04T13:39:33Z", GoVersion:"go1.6.2", Compiler:"gc", Platform:"linux/amd64"}version Client Version: version.Info{Major:"1", Minor:"3+", GitVersion:"v1.3.1-dirty", GitCommit:"fe4aa01af2e1ce3d464e11bc465237e38dbcff27", GitTreeState:"dirty", BuildDate:"2016-09-15T15:47:40Z", GoVersion:"go1.6.2", Compiler:"gc", Platform:"linux/amd64"} Server Version: version.Info{Major:"1", Minor:"3", GitVersion:"v1.3.1.1+9ec21ad3522752", GitCommit:"9ec21ad3522752415c2f82db9f6aa1117dbe583d", GitTreeState:"clean", BuildDate:"2016-10-04T13:39:33Z", GoVersion:"go1.6.2", Compiler:"gc", Platform:"linux/amd64"}
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：
Oct 5 12:50:29.746: INFO: Controller my-hostname-basic-f2fde265-8ab6-11e6-85bb-2c768adbb5f8: Replica 2 [my-hostname-basic-f2fde265-8ab6-11e6-85bb-2c768adbb5f8-ekio4] expected response "my-hostname-basic-f2fde265-8ab6-11e6-85bb-2c768adbb5f8-ekio4" but got "my-hostname-basic-f2fde265-8ab6-11e6-85bb-2c768adbb5f8-ekio4\n"
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
