Gardener Extension for Image Rewrites

This project provides a Gardener extension that replaces pod image references for system components of shoot clusters. Additionally, it can handle mirror configuration for containerd.

Components

• Mutating webhook for shoots to replace image references of Pods running in the kube-system namespace.
• Mutating webhook for seeds to replace image references in OperatingSystemConfig resources.
• Mutating webhook for seeds to add containerd configuration to OperatingSystemConfig resources.

Configuration

A separate configuration file is used to define the image rewrites. Please see here for an example.
