kubewatch
kubewatch is a Kubernetes watcher that currently publishes notification to Slack. Run it in your k8s cluster, and you will get event notifications in a slack channel.
TL;DR;
$ helm install stable/kubewatch
Introduction
This chart bootstraps a kubewatch deployment on a Kubernetes cluster using the Helm package manager.
Installing the Chart
To install the chart with the release name my-release:
$ helm install stable/kubewatch --name my-release
The command deploys kubewatch on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.
Uninstalling the Chart
To uninstall/delete the my-release deployment:
$ helm delete my-release
The command removes all the Kubernetes components associated with the chart and deletes the release.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,
$ helm install stable/kubewatch --name my-release \
--set=slack.channel="#bots",slack.token="XXXX-XXXX-XXXX"
Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
$ helm install stable/kubewatch --name my-release -f values.yaml
Tip
: You can use the default values.yaml
Create a Slack bot
Open https://my.slack.com/services/new/bot to create a new Slack bot.
The API token can be found on the edit page (it starts with xoxb-).
Invite the Bot to your channel by typing /join @name_of_your_bot in the Slack message area.
