Kubeat

A logger for the k8s without any logfiles.

Why

In some situations such as not own K8S installation or restricted permissions, we can't use logging based on the files via DaemonSet. But, K8S has a pods logging API. The Kubeat do per namespace logging simple.

How to use

Setup it via the Helm.

cd helm/kubeat
emacs values.yaml
helm install .
