KHole

Sends alerts from crashed K8s pods to Slack. This is a simple tool that can be used to monitor your Kubernetes cluster.

An example Slack message

Installation

kubectl apply -f https://github.com/cloud-native-skunkworks/khole/releases/download/latest/release.yaml

Apply the CR with your details

kubectl apply -f config/samples/core_v1alpha1_kholeconfiguration.yaml

Development

This is a typical kubebuilder project. It has no webhook so you can just go run as long as you have a valid KUBECONFIG env. You'll need to install the custom resources.

If you want to build the docker image just override the IMG env variable in the make file e.g. IMG=your-registry/khole:latest make docker-build
