what

helmfiles:
  - https://raw.githubusercontent.com/cloudposse/helmfiles/0.6.1/helmfile.d/0020.kiam.yaml
  - https://raw.githubusercontent.com/cloudposse/helmfiles/0.7.0/helmfile.d/0100.external-dns.yaml

why

• Create definitions that stitch together different versions of helmfile definitions
• Do not force upgrades of all helmfiles just because one file was updated

use-case

We write a lot of helmfiles used by different organizations. We version pin to a release of our helmfiles distribution, however, sometimes users need to update only one specific service and are not ready to upgrade all services in a given release of helmfiles.

Using the approach above works more like terraform modules empowering the user to surgically import resources into their environment, while keeping it DRY and CODEOWNERS friendly by using a single source of truth.
