KODeR

Kubernetes Operator for Deployment Restarts

Problem

Sometimes your Deployments get stuck in an unavailable state, where only a restart helps (and a readiness or liveness probe doesn't). Or maybe you just want to restart an application in a regular interval.

Then KODeR may come to the rescue.

It simply tracks all deployments with koder annotations.

Installation

Use and modify the manifests in ./deploy to your needs. This will deploy KODeR and the necessary service account in a namespace koder.

Usage

There are two possible annotations that can be supplied to deployments:

• koder/restart-time: A value indicating the interval to restart the application OR the checking interval to restart on unavailability (30s, 20m, 4h, 3d)
• koder/restart-unavailable: Restart a container that wont start properly (stuck in unavailable, assuming a restart solves the problem) (true)
