• Controllers: Contains all Kubernetes pods in the "flux-system" namespace as its children
• Releases: Contains all helm release config items as its children
• Repos: Contains all Helm repository config items as its children
• Kustomizations: Contains all Kustomization config items as its children
• Git: Contains all Git repository config items as its children
