Functions

func ReadConfigSource

func ReadConfigSource(ctx context.Context, client client.Clientset, nodeName string, source ConfigSource) (config map[string]string, descriptions []string, err error)

func ResolveConfigurations

func ResolveConfigurations(ctx context.Context, client client.Clientset, nodeName string, sources []ConfigSource, allowConfigKeys, denyConfigKeys []string) (map[string]string, error)

func WriteConfigurations

func WriteConfigurations(ctx context.Context, destDir string, data map[string]string) error

WriteConfigurations writes the key-value pairs in data to destDir. It writes it like a Kubernetes config-map: It uses a double-layer symlink to allow for atomic updates: destDir/key -> ..data/key ..data -> ..data_$time

Types

type ConfigSource

type ConfigSource struct {
	Kind      string // one of config-map, overrides, node
	Namespace string // The namespace for the ConfigMap or CiliumNodeConfigs
	Name      string // The name of the ConfigMap or Node, unused for Overrides
}

func (*ConfigSource) String

func (cs *ConfigSource) String() string
