Hi @ainoya! The bases field has actually been deprecated and the equivalent functionality is now provided by the resources field.

I'm fairly certain the problem is you are using a version of kustomize lower than v2.1.0, please upgrade and try the example again.

Ah, sorry. I've used an older version. Thanks for your advice and I close this PR.
