以对话的形式管理你的Kubernetes集群
BotKubeBotKube 是一个用于监控和调试 Kubernetes 集群的消息传递工具。 BotKube 可以与多个消息传递平台（如 Slack、Mattermost 或 Microsoft Teams）集成，以帮助您监控 Kubernetes 集群、调试关键部署，并通过对 Kubernetes 资源运行检查来提供标准实践建议。
安装BotKube
1、本文使用slack作为消息接收平台，需要自行注册slack,拿到Access token
xoxb-2169032185141-2256603089394-qeLWxe0sUtwfdlwnk6VWbw11 2、将 BotKube 用户添加到 Slack 频道
将 BotKube 应用程序安装到您的 Slack 工作区后，您会看到一个名为“BotKube”的新机器人用户添加到您的工作区中。 将该机器人添加到您想要接收通知的 Slack 频道。
（您可以通过在频道中邀请@BotKube 来添加它）
3、使用helm把BotKube安装到kubernrtes集群
helm repo add infracloudio https://infracloudio.github.io/chartshelm repo update请自行替换<>内的信息：helm install --version v0.12.1 botkube --namespace botkube \ --set communications.slack.enabled=true \ --set communications.slack.channel=<SLACK_CHANNEL_NAME> \ --set communications.slack.token=<SLACK_API_TOKEN_FOR_THE_BOT> \ --set config.settings.clustername=<CLUSTER_NAME> \ --set config.settings.kubectl.enabled=<ALLOW_KUBECTL> \ --set image.repository=infracloudio/botkube \ --set image.tag=v0.12.1 \ infracloudio/botkube- SLACK_CHANNEL_NAME 是添加@BotKube 的频道名称- SLACK_API_TOKEN_FOR_THE_BOT 是将 BotKube 应用程序安装到 Slack 工作区后收到的令牌- CLUSTER_NAME 是在传入消息中设置的集群名称- ALLOW_KUBECTL 设置为 true 以允许 BotKube 在集群上执行 kubectl 命令 4、查看安装信息
# helm list -n botkubeNAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSIONbotkube botkube 1 2021-07-09 10:41:35.813245746 +0800 CST deployed botkube-v0.12.1 v0.12.1# kubectl get all -n botkubeNAME READY STATUS RESTARTS AGEpod/botkube-747ff4dc5d-795hz 1/1 Running 0 2d22hNAME READY UP-TO-DATE AVAILABLE AGEdeployment.apps/botkube 1/1 1 1 2d22hNAME DESIRED CURRENT READY AGEreplicaset.apps/botkube-747ff4dc5d 1 1 1 2d22h 5、如果你需要修改配置，可以更新botkube-configmap,默认设置如下

1、先ping下BotKube，看看输出
2、查看可使用的命令
3、以对话的形式执行kubectl命令，例如获取pod,更多命令可以自己测试…
4、验证slack收集kubernetes事件信息，例如创建一个新的pod,这里以nginx为例
我这里直接用lens连接集群，创建一个名为nginx的deployment，
直接创建即可，然后来到slack可以看到如下信息，即botkube将这个create事件消息推送到了你的slack频道。
现在删除deployment,再看slack频道,收到delete的消息
更多好玩的功能，请自行体会吧。。。
