Types

type DataSync

type DataSync struct {
	FlagData string
	Source   string
	Type
}

DataSync is the data contract between Runtime and sync implementations

type ISync

type ISync interface {
	// Init is used by the sync provider to initialize its data structures and external dependencies.
	Init(ctx context.Context) error

	// Sync is the contract between Runtime and sync implementation.
	// Note that, it is expected to return the first data sync as soon as possible to fill the store.
	Sync(ctx context.Context, dataSync chan<- DataSync) error

	// ReSync is used to fetch the full flag configuration from the sync
	// This method should trigger an ALL sync operation then exit
	ReSync(ctx context.Context, dataSync chan<- DataSync) error

	// IsReady shall return true if the provider is ready to communicate with the Runtime
	IsReady() bool
}

ISync implementations watch for changes in the flag sources (HTTP backend, local file, K8s CRDs ...),fetch the latest value and communicate to the Runtime with DataSync channel

type SourceConfig

type SourceConfig struct {
	URI      string `json:"uri"`
	Provider string `json:"provider"`

	BearerToken string `json:"bearerToken,omitempty"`
	AuthHeader  string `json:"authHeader,omitempty"`
	CertPath    string `json:"certPath,omitempty"`
	TLS         bool   `json:"tls,omitempty"`
	ProviderID  string `json:"providerID,omitempty"`
	Selector    string `json:"selector,omitempty"`
	Interval    uint32 `json:"interval,omitempty"`
}

SourceConfig is configuration option for flagd. This maps to startup parameter sources

type Type

type Type int

const (
	// ALL - All flags of sync provider. This is the default if unset due to primitive default
	ALL Type = iota
	// ADD - Additional flags from sync provider
	ADD
	// UPDATE - Update for flag(s) previously provided
	UPDATE
	// DELETE - Delete for flag(s) previously provided
	DELETE
)

Type of the sync operation

func (Type) String

func (t Type) String() string
