Variables ¶

var DefaultComponentGlobalsRegistry basecompatibility.ComponentGlobalsRegistry = basecompatibility.NewComponentGlobalsRegistry()

DefaultComponentGlobalsRegistry is the global var to store the effective versions and feature gates for all components for easy access. Example usage: // register the component effective version and feature gate first wardleEffectiveVersion := basecompatibility.NewEffectiveVersion("1.2") wardleFeatureGate := featuregate.NewFeatureGate() utilruntime.Must(compatibility.DefaultComponentGlobalsRegistry.Register(apiserver.WardleComponentName, wardleEffectiveVersion, wardleFeatureGate, false))

cmd := &cobra.Command{
 ...
	// call DefaultComponentGlobalsRegistry.Set() in PersistentPreRunE to ensure the feature gates are set based on emulation version right after parsing the flags.
	PersistentPreRunE: func(*cobra.Command, []string) error {
		if err := compatibility.DefaultComponentGlobalsRegistry.Set(); err != nil {
			return err
		}
 ...
	},
	RunE: func(c *cobra.Command, args []string) error {
		// call compatibility.DefaultComponentGlobalsRegistry.Validate() somewhere
	},
}

flags := cmd.Flags() // add flags compatibility.DefaultComponentGlobalsRegistry.AddFlags(flags)

Functions ¶

func DefaultBuildEffectiveVersion ¶

func DefaultBuildEffectiveVersion() basecompatibility.MutableEffectiveVersion

DefaultBuildEffectiveVersion returns the MutableEffectiveVersion based on the current build information.

func DefaultKubeEffectiveVersionForTest ¶

func DefaultKubeEffectiveVersionForTest() basecompatibility.MutableEffectiveVersion

DefaultKubeEffectiveVersionForTest returns the MutableEffectiveVersion based on the latest K8s release hardcoded in DefaultKubeBinaryVersion. DefaultKubeBinaryVersion is hard coded because defaultBuildBinaryVersion would return 0.0 when test is run without a git tag. We do not enforce the N-3..N emulation version range in tests so that the tests would not automatically fail when there is a version bump. Only used in tests.
