如何在 Kubernetes 中执行主 go 脚本

【问题标题】：How to execute the master go scritpt in kubernetes如何在 Kubernetes 中执行主 go 脚本
【发布时间】：2020-05-02 01:49:04
【问题描述】：

我们在以下 URL 中找到了测试列表。谁能让我知道执行端到端 kubernetes 测试的测试列表的主要 go 脚本。 https://github.com/kubernetes/kubernetes/tree/master/test/e2e

我们已经在 Ubuntu 中安装了 kubernetes，并尝试获取执行所有 e2e 测试的主脚本。

我在安装 kubetest 时遇到问题。请帮我解决问题。完整信息如下。

chan@coe-OptiPlex-3060:~$ kubetest --extract=v1.13.0 kubetest：找不到命令

【问题讨论】：

  • 该目录中的README.md 文件似乎链接到一些相当广泛的文档。你有什么问题？
  • 嗨，David Maze，我正在寻找主要脚本名称。这样我就可以使用 go run 命令运行 go 脚本。我也在寻找任何其他方法来执行端到端一致性测试。

标签： go kubernetes


【解决方案1】：

按照下面提到的步骤：

安装 Go

wget https://dl.google.com/go/go1.12.1.linux-amd64.tar.gz

sudo tar -C /usr/local -xzf go1.12.1.linux-amd64.tar.gz
export GOPATH="/home/vagrant/go"
export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin

安装 kubetest

go get -v -u k8s.io/test-infra/kubetest

提取版本

kubetest --extract=v1.13.0

cd kubernetes

针对本地集群进行测试

export KUBECONFIG=/path/to/kubeconfig
export KUBE_MASTER_IP="http://127.0.0.1:<PORT>"
export KUBE_MASTER_IP="127.0.0.1:<PORT>"
export KUBE_MASTER=local



kubetest --test --provider=skeleton --test_args="--ginkgo.focus=\[Conformance\]" | tee test.out

【讨论】：

  • 感谢 Prakash 提供的详细信息。我尝试安装 kubetest，但它抛出的状态码为 200。我在这篇文章的描述部分提到了日志。
  • 这些确实是文档化的说明。但是，文档说明不起作用，即使对于 1.13。祝一切顺利。
  • 这是 Udemy 课程中的当前问题； e2e以前是这样安装的，现在没有。
【解决方案2】：

这对我有用，不确定是否所有步骤都是必要的：

# get kubetest, ginkgo and gomega

go get -u k8s.io/test-infra/kubetest
go get github.com/onsi/ginkgo/ginkgo
go get github.com/onsi/gomega/...

# Install Google SDK: https://cloud.google.com/sdk/docs/downloads-versioned-archives
# Login into Google Developer Cloud, necessary to fetch kubetest binaries with extract command

gcloud auth login

# Get the binaries
# WARNING: it removes all directories with kubernetes in the name (weird), it removed my kubernetes-the-hard-way repo, thus better switch to an empty dir before proceeding
kubetest --extract=v1.18.2
cd kubernetes

# Get the kubernetes client config
# I am using my own setup to deploy k8s using ansible/kubeadm here: https://github.com/earthquakesan/kubernetes-the-hard-way
# simply go into vagrant/, then do vagrant up
# after VMs are up, follow the 18-kubeadm.md guide

scp master-1:/home/vagrant/.kube/config ./

# Finally run the tests

export KUBECONFIG=$(pwd)/config
export KUBE_MASTER_IP=192.168.5.30:6443
export KUBE_MASTER_URL=https://192.168.5.30:6443
export KUBE_MASTER=master-1
export KUBERNETES_PROVIDER=skeleton
kubetest --test --test_args="--ginkgo.focus=\[Conformance\]" > test.out
