Secret Primitive Example

This example demonstrates the usage of the secret primitive within the operator component framework. It shows how to manage a Kubernetes Secret as a component of a larger application, utilising features like:

• Base Construction: Initializing a Secret with basic metadata and type.
• Feature Mutations: Composing secret entries from independent, feature-gated mutations using SetStringData.
• Metadata Mutations: Setting version labels on the Secret via EditObjectMetadata.
• Data Extraction: Harvesting Secret entries after each reconcile cycle.

Directory Structure

• app/: Defines the controller that uses the component framework. The ExampleApp CRD is shared from examples/shared/app.
• features/: Contains modular feature definitions:
  • mutations.go: base credentials, version labelling, and feature-gated tracing and metrics tokens.
• resources/: Contains the central NewSecretResource factory that assembles all features using secret.Builder.
• main.go: A standalone entry point that demonstrates multiple reconciliation cycles with a fake client.

Running the Example

go run examples/secret-primitive/main.go

This will:

1. Initialize a fake Kubernetes client.
2. Create an ExampleApp owner object.
3. Reconcile through four spec variations, printing the secret entries after each cycle.
4. Print the resulting status conditions.
