Recursively finds all local Helm Charts and materializes the full resultant YAML in an adjacent file called helm.materialized.yaml in each directory
|
|
|
|
The runs 'pluto detect-files -d .' in each directory to detect deprecated API objects inherited from embedded Helm charts affecting your Kubernetes cluster upgrades
|
|
|
|
If you are using internal private Helm repos, you will need to add them to your machine before running this
|
|
|
|
Pluto is run per directory as a workaround for this recursion issue:

Parallelized for performance

|

Requires 'helm', 'pluto' and 'yq' binaries to be in the \$PATH - will attempt to install them if not found
