A command line utility to publish, fetch, customize, validate, and apply Kubernetes configuration.


Kustomizer is an OSS tool for building Kubernetes continuous delivery workflows.

Distribute Kubernetes configuration as OCI artifacts to container registries:

  • kustomizer push artifact oci://: -k [-f] [-p]
  • kustomizer tag artifact oci://:
  • kustomizer pull artifact oci://:
  • kustomizer inspect artifact oci://:

Build, customize and apply Kubernetes resources:

  • kustomizer build inventory [-a ] [-f ] [-p ] -k
  • kustomizer apply inventory -n [-a] [-f] [-p] -k --prune --wait --force
  • kustomizer diff inventory -n [-a] [-f] [-p] -k

Manage the applied Kubernetes resources:

  • kustomizer get inventories --namespace
  • kustomizer inspect inventory --namespace
  • kustomizer delete inventory --namespace
