Version Build Status Docker Repository on Quay Go Report Card

Kubernetes Node Drainer helps to evict pods from nodes before shutdown.

It is a single statically compiled binary in a minimal container (FROM scratch) run as non-root user.

How it works

A small binary run as a DaemonSet and listenning for a trigger (e.g. AWS ASG Lifecycle Hook). When triggered it uses Kubernetes Eviction API to drain the node (just like the kubectl drain command).

Supported Triggers

The code is prepared for multiple trigger providers if there is a community interest in such functionality, but currently supported triggers are:

Contribution

Feel free to create a GitHub Issue for any questions, bug reports or feature requests, also Pull Requests are welcome, just make sure you discuss any major changes before investing a lot of time.
