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)
使用helm把BotKube安装到kubernrtes集群
- helm repo add infracloudio https://infracloudio.github.io/charts
- helm 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=
\ - --set communications.slack.token=
\ - --set config.settings.clustername=
\ - --set config.settings.kubectl.enabled=
\ - --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

- # helm list -n botkube

5、如果你需要修改配置,可以更新botkube-configmap,默认设置如下

使用Slack与BotKube对话
先ping下BotKube,看看输出
查看可使用的命令
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…
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。。。
