About:
Kustomizer is a command-line tool that packages and distributes Kubernetes configuration sets as OCI artifacts. It enables version-controlled, immutable deployments by treating infrastructure manifests like container images. This approach simplifies the management and synchronization of complex Kubernetes environments across clusters.

Key Features:

Packages Kubernetes manifests as OCI artifacts
Supports GitOps-style synchronization and reconciliation
Integrates with standard OCI registries (Docker Hub, GHCR, etc.)
Provides atomic upgrades and rollbacks
Verifies artifact signatures for security

Use Cases:

Sharing and versioning reusable Kubernetes components
Implementing GitOps workflows without requiring a Git repository on the cluster
Auditing and securing infrastructure changes with cryptographic signatures

Alternatives:

Flux – Flux is a full GitOps controller, while Kustomizer is a CLI tool that leverages OCI registries for distribution.
Helm – Helm uses templated charts, whereas Kustomizer focuses on packaging raw, overlayed Kubernetes manifests.
