Robusta UI
结论
今天我想分享一个有趣的项目叫做 “K8s ChatGPT Bot[1]”。该项目的目的是为 K8s 集群部署一个 ChatGPT 机器人。我们可以询问 ChatGPT 帮助我们解决 Prometheus 的警报,可以得到简洁的答复,不再需要一人在黑暗中独自解决警报问题!
我们需要用到 Robusta[2],如果你还没有 Robusta,可以参考《K8s — Robusta, K8s Troubleshooting Platform[3]》搭建一个 Robusta 平台。
下图是 Robusta 平台如何工作的截图:
你可以在此处查看完整的演示视频:

运行 K8s ChatGPT 机器人项目
该机器人项目是基于 Robusta.dev[4] 实现的,Robusta.dev 是一个用于响应 K8s 警报的开源平台。其工作流程大致如下:
Prometheus 使用 Webhook 接收器将警报转发给 Robusta.dev 。
Robusta.dev 询问 ChatGPT 如何修复 Prometheus 警报。

如何安装 Robusta
生成 Robusta 配置文件
为 Robusta 准备 Python 虚拟环境。
$ python3.10 -m venv robusta
$ source robusta/bin/activate
(robusta) $ pip install -U robusta-cli --no-cache
Collecting robusta-cli

使用 robusta 生成一个配置文件:
$ robusta gen-config
Robusta reports its findings to external destinations (we call them "sinks").
We'll define some of them now.Configure Slack integration? This is HIGHLY recommended. [Y/n]: Y
If your browser does not automatically launch, open the below url:
https://api.robusta.dev/integrations/slack?id=xxxx
配置 Slack 集成
使用浏览器打开网页:https://api.robusta.dev/integrations/slack?id=xxxx
更新权限:
恭喜你配置 Slack 集成成功。
现在回到我们的 Terminal 终端,我们可以看到以下内容,说明操作成功:
$ robusta gen-config
Robusta reports its findings to external destinations (we call them "sinks").
We'll define some of them now.Configure Slack integration? This is HIGHLY recommended. [Y/n]: Y
If your browser does not automatically launch, open the below url:
https://api.robusta.dev/integrations/slack?id=xxxx
You've just connected Robusta to the Slack of: devopsfans
Which slack channel should I send notifications to? # k8s-chatgpt-bot
Configure Robusta UI sink? This is HIGHLY recommended. [Y/n]: Y
Enter your Gmail/Google address. This will be used to login: xxx@gmail.com
Choose your account name (e.g your organization name): devopsfans
Successfully registered.Robusta can use Prometheus as an alert source.
If you haven't installed it yet, Robusta can install a
pre-configured Prometheus.
Would you like to do so? [y/N]: y
Please read and approve our End User License Agreement:
https://api.robusta.dev/eula.html
Do you accept our End User License Agreement? [y/N]: y
Last question! Would you like to help us improve Robusta by sending exception reports? [y/N]: N
Saved configuration to ./generated_values.yaml - save this file for future use!
Finish installing with Helm (see the Robusta docs).
Then login to Robusta UI at https://platform.robusta.devBy the way, we'll send you some messages later to get feedback.
(We don't store your API key, so we scheduled future messages using Slack's
API)
在 slack channel 中,我们还可以看到:
使用 Helm3 安装 Robusta
安装和更新 robusta 仓库。
$ helm repo add robusta https://robusta-charts.storage.googleapis.com && helm repo update
"robusta" has been added to your repositories
Hang tight while we grab the latest from your chart repositories...

Update Complete. ⎈Happy Helming!⎈
更新 generated_values.yaml 文件
使用以下内容更新 generated_values.yaml 文件:
playbookRepos:chatgpt_robusta_actions:url: "https://github.com/robusta-dev/kubernetes-chatgpt-bot.git"customPlaybooks:
# Add the 'Ask ChatGPT' button to all Prometheus alerts
- triggers:- on_prometheus_alert: {}actions:- chat_gpt_enricher: {}globalConfig:chat_gpt_token: YOUR KEY GOES HERE
将 Robusta 部署到 K8s
$ helm install robusta robusta/robusta -f ./generated_values.yaml \
--set clusterName=dev-cluster
验证两个 Robusta pod 正常运行且在日志中没有发现错误日志:

使用 Robusta
现在,我们终于可以使用 Robusta 了!默认情况下,Robusta 在当 K8s Pod 崩溃时发送通知。
因此,让我们创建一个崩溃的 Pod:
$ kubectl apply -f https://gist.githubusercontent.com/robusta-lab/283609047306dc1f05cf59806ade30b6/raw
deployment.apps/crashpod created$ kubectl get pods -A | grep crash
default crashpod-64db77b594-cgz4s 0/1 CrashLoopBackOff 2 (21s ago) 36s
一旦 Pod 达到两次重启,在 Slack channel 我们就将收到有关 Pod 崩溃的消息,如下所示:
与 ChatGPT 互动
经过我们的实验,我们已经确认 Robusta 已与我们的 Slack 和 K8s 集群集成。接下来让我们与 ChatGPT 机器人进行交互!
立即触发 Prometheus 警报,跳过正常延迟:

现在切换到 Slack,我们将看到一个新警报,并且这次带有 “Ask ChatGPT” 的按钮!
就是这样!恭喜,我们刚刚成功安装了我们的第一个 K8s ChatGPT 机器人!
示例 2:节点容量为 100%
下面是一个节点达到 100% 容量的例子:
Robusta UI
Robusta 有一个用于集成的 UI,也有一个预配置的 Promethus 系统,如果你还没有自己的 K8s 集群,并且想尝试一下这个 ChatGPT 机器人,你可以使用 Robusta 现有的!
结论
我们花了一些时间终于把 K8s + ChatGPT 平台搭建起来了。这是一个由爱好者们共同组建的项目,并且此项目具有很大的潜力。我希望你喜欢这篇文章。
如果你还没有自己的 K8s 集群和 Prometheus 监控系统,你可以使用 Robusta 预配置的 Promethus 监控系统。
