Helmfile is a declarative spec for deploying helm charts. It lets you...

* Keep a directory of chart value files and maintain changes in version control.
* Apply CI/CD to configuration changes.
* Periodically sync to avoid skew in environments.

To avoid upgrades for each iteration of helm, the helmfile executable delegates to helm - as a result, helm must be installed.

The fstrcmp package provides a library which may be used to make fuzzy
comparisons of strings and byte arrays. It also provides simple
commands for use in shell scripts.
