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.

N.B. this chart is deprecated and has been moved to stable.

TL;DR;

console

$ helm install incubator/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:

console

$ helm install incubator/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:

console

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

`rbac.serviceAccountName`	existing ServiceAccount to use (ignored if rbac.create=true)	`default`
`replicaCount`	desired number of pods	`1`

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

console

$ helm install incubator/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,

console

$ helm install incubator/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.
