### Migration

Check out the [Pydantic migration guide](https://docs.pydantic.dev/2.0/migration/).

For the things that need changes in your Pydantic models, the Pydantic team built [`bump-pydantic`](https://github.com/pydantic/bump-pydantic).

  
  This is a new major release of kustomize, so there are a few backwards-incompatible changes, most of which are rare use cases, bug fixes with side effects, or things that have been deprecated for multiple releases already:
  

message VolumeSource {
  // hostPath represents a pre-existing file or directory on the host
  // machine that is directly exposed to the container. This is generally
  // used for system agents or other privileged things that are allowed
  // to see the host machine. Most containers will NOT need this.
  // More info: https://kubernetes.io/docs/concepts/storage/volumes#hostpath
  // ---
