func PluginsForFilter ¶

func PluginsForFilter(
	ctx context.Context,
	logger logr.Logger,
	cl client.Client,
	httpRoute *gwtypes.HTTPRoute,
	rule gwtypes.HTTPRouteRule,
	filter gwtypes.HTTPRouteFilter,
	pRef *gwtypes.ParentReference,
) ([]configurationv1.KongPlugin, error)

PluginsForFilter creates or retrieves KongPlugins for the given HTTPRoute filter.

Workflow:

1. If the filter type is ExtensionRef retrieve the referenced KongPlugin.
2. Otherwise, translates the filter into one or more plugin configurations.
3. For each plugin configuration: - Derives the KongPlugin name using namegen. - Builds a new KongPlugin resource with appropriate name, namespace, labels, annotations, and config. - Calls translator.VerifyAndUpdate to handle existing plugin reconciliation.
4. Returns all translated plugins.

Self-managed plugin:

A plugin referenced via ExtensionRef. These are returned as-is without rebuild,
annotation modification, or existence checks. The user is responsible for managing
the plugin lifecycle.

Parameters:

• ctx: Context for API calls.
• logger: Structured logger.
• cl: Kubernetes client.
• httpRoute: Source HTTPRoute.
• rule: The HTTPRouteRule being processed.
• filter: The HTTPRouteFilter being processed.
• pRef: Parent (Gateway) reference.

Returns:

• kongPlugins: The translated plugin(s).
• err: Any error encountered.
