Functions

func EnforceClusterConfig

func EnforceClusterConfig(
	ctx context.Context, clusterName string, config cmtypes.CiliumClusterConfig,
	backend ClusterConfigBackend, log logrus.FieldLogger,
) (stopAndWait func(), err error)

EnforceClusterConfig synchronously writes the cluster configuration, and additionally registers a background task to periodically enforce its presence (e.g., in case the associated lease unexpectedly expired).

func GetClusterConfig

func GetClusterConfig(ctx context.Context, clusterName string, backend ClusterConfigBackend) (cmtypes.CiliumClusterConfig, error)

func SetClusterConfig

func SetClusterConfig(ctx context.Context, clusterName string, config cmtypes.CiliumClusterConfig, backend ClusterConfigBackend) error

Types

type ClusterConfigBackend

type ClusterConfigBackend interface {
	Get(ctx context.Context, key string) ([]byte, error)
	UpdateIfDifferent(ctx context.Context, key string, value []byte, lease bool) (bool, error)
}
