usage_description="

|
Filter program to generate ArgoCD namespace resource whitelist from a given Kubernetes YAML or Kustomize build output
|
|
|
|
YAML can be supplied as a file argument or via standard input. If no file is given, waits for stdin like a standard unix filter program
|
|
|
|
Outputs YAML for the namespaceResourceWhitelist section of argocd-project.yaml
|
|
|
|
A full argocd-project.yaml is already provided at the URL below with all the most common object permissions already populated via the output from this script against my production environment

|

|
|
|
Uses adjacent script kubernetes_resource_types.sh
|
|
|
|
Tested on ArgoCD 2.0.3
