在 Kubernetes 中部署 Prow
GitHub CI 🤖️ by Kubernetes
Prow | praʊ |
noun. the pointed front part of a ship; the bow. 船首.
了解 Prow 可以参考这篇知乎专栏:Kubernetes 原生 CI/CD 系统 Prow 简介。
本文重点参考了以下文章,并做了一些问题的修复:
我们并不一定需要使用 Bazel 来构建配置。笔者使用的 Kubernetes 版本为 2020 年发布的 1.19.3。一切的前提是拥有一个 Kubernetes 集群,最好在里面也部署一个 Ingress Controller 用来暴露我们的 WebHook 以及 Prow Deck 前端 Dashboard 服务。
在 K8s 集群中部署 Prow 的具体步骤如下:
首先注册一个 GitHub 账号专门用于作为机器人账号,用此账号前往 GitHub Developer 页面创建一个 Token,权限参考上文,并邀请此账号作为 Collaborators 管理仓库。
随机生成 H-MAC 作为 WebHook 密码安全验证。
openssl rand -hex 20 > hmac
将他们保存在 /etc/github/oauth
和 /etc/webhook/hmac
文件下。路径不能错误,因为此处和下面的 Prow manifest 字段匹配。
纳入集群对象:
kubectl create secret generic hmac-token --from-file=hmac=/etc/webhook/hmac
kubectl create secret generic oauth-token --from-file=oauth=/etc/github/oauth
将以下 Prow 的 manifest 做简单修改,注意 Ingress 的域名,namespace 为 default

apply 上述 manifest。过程可能持续几分钟。上面用到的镜像都来自 DockerHub,国内可以直接访问。出现问题尝试打印 Pod 日志或者 describe,用好 Google 和 GitHub 能解决几乎 99% 的技术问题。
curl -L https://git.io/JIJ4c -o prow.yaml
vi prow.yaml
kubectl apply -f prow.yaml
Deck | dɛk |
noun. 甲板
等 Pod 全都 Running 后,项目就成功了一半!现在直接访问 Prow 的 Ingress 地址,可以看到 Prow 的 Deck 前端 Dashboard,类似于:https://prow.k8s.io/ 。
这时,可以在 GitHub 的项目设置里去添加 WebHook:
- Payload URL 是你的 Prow Ingress 域名后面直接加
/hook
- Content Type 选择
application/json
- Secrets 是上面随机生成的 HMAC
- 勾选
Send me everything
激活并保存。
接着在集群机器上创建一个 plugins.yaml
文件和 config.yaml
文件来配置 Prow。
插件的声明:
plugins:
GitHub账号/项目名:
- size
- cat
- dog
- pony
- shrug
- yuks
- label

应用更改:
kubectl create configmap plugins \
--from-file=plugins.yaml=/root/cluster/prow/plugins.yaml --dry-run -o yaml \
| kubectl replace configmap plugins -f -
kubectl create configmap config \
--from-file=config.yaml=/root/cluster/prow/config.yaml --dry-run -o yaml \
| kubectl replace configmap config -f -
可能需要两分钟生效。等一切就绪后,就可以创建 Pull Request 来测试了。效果可以参考 Kubernetes 的官方仓库或我的这个 node 命令行翻译项目。
使用 Prow
在 GitHub 的 Issue 或 Pull Request 页面下你可以用一个简单的 /meow
命令让机器人随机发送一张 🐱 的图片。无需任何刷新,GitHub 页面会自动地更新此页面(后来发现是基于 WebSocket):
我们注意到, Kubernetes 维护人员会使用 /test
命令来让集群内的 Pod 执行测试并将结果告诉 GitHub,这就是 ProwJob 实现的了。
ProwJob 主要用于 PR 流程的 CI 测试,而国内网络原因无法使用 Google 的 GCS 服务,ProwJob 中 plank 依赖的 Pod Utilities,其中定义 GCS Bucket 用于存放构建产物、日志等内容,因此,我们似乎只能自己用自定义的镜像来跑临时 CI 任务了。注意定义 presubmit 字段下的 decorate 为 false,并利用好 Prow 提供的一些环境变量。
下面是我的一个简单的 Spring Boot 项目利用 Maven 镜像(配合阿里云的 Maven Repo)来做的 presubmits,同样在 config.yaml 中添加:
presubmits:
Lonor/kubernetes-springboot-demo:
- name: spring
decorate: false
always_run: false
spec:
containers:
- image: lawrence2018/maven:3.6-jdk-8
command: ["/bin/sh", "-c"]
args:
- |
mkdir -p /${REPO_NAME}
cd /${REPO_NAME}
git init
git remote add origin https://github.com/${REPO_OWNER}/${REPO_NAME}.git
git fetch origin pull/${PULL_NUMBER}/head:pr-${PULL_NUMBER}
git checkout pr-${PULL_NUMBER}
mvn test
resources:
requests:
cpu: "2000m"
memory: "1536Mi"
重新配置 config 后并应用更改,在 Pull Request 下评论 /test all
或者 /test spring
来触发测试。参考此 PR。
/test
后面加 presubmits 的 name 名可触发指定的测试 Pod,all 则测试全部。测试若失败,可使用 /retest
来重新测试。
如果测试通过,可使用 /lgtm
触发 tide 让机器人合并代码(注意自己不能 /lgtm
)。
自研 Issue/PR Bot
GitHub 大规模使用 WebSocket 来动态修改 Issue 或 PR 页面的 DOM,在视觉上非常令人享受。笔者后来也参考 Prow 用 Go 写了一个简单了 OpsBot 帮助自己的仓库做一些简单的 PR、Issue 的管理,现已开源,欢迎任何 Issue / PR!
