Types

type Backend

type Backend struct {
	Client     *clientv3.Client
	Daemons    []daemon.Daemon
	Etcd       *etcd.Etcd
	Store      store.Store
	EventStore EventStoreUpdater
	// contains filtered or unexported fields
}

Backend represents the backend server, which is used to hold the datastore and coordinating the daemons

func Initialize

func Initialize(config *Config) (*Backend, error)

Initialize instantiates a Backend struct with the provided config, by configuring etcd and establishing a list of daemons, which constitute our backend. The daemons will later be started according to their position in the b.Daemons list, and stopped in reverse order

func (*Backend) Run

func (b *Backend) Run() error

Run starts all of the Backend server's daemons

func (*Backend) Stop

func (b *Backend) Stop()

Stop the Backend cleanly.

type Config

type Config struct {
	// Backend Configuration
	StateDir string
	CacheDir string

	// Agentd Configuration
	AgentHost string
	AgentPort int

	// Apid Configuration
	APIListenAddress string
	APIURL           string

	// Dashboardd Configuration
	DashboardHost        string
	DashboardPort        int
	DashboardTLSCertFile string
	DashboardTLSKeyFile  string

	// Pipelined Configuration
	DeregistrationHandler string

	// Etcd configuration
	EtcdAdvertiseClientURLs      []string
	EtcdInitialAdvertisePeerURLs []string
	EtcdInitialClusterToken      string
	EtcdInitialClusterState      string
	EtcdInitialCluster           string
	EtcdListenClientURLs         []string
	EtcdListenPeerURLs           []string
	EtcdName                     string
	NoEmbedEtcd                  bool

	// Etcd TLS configuration
	EtcdClientTLSInfo     etcd.TLSInfo
	EtcdPeerTLSInfo       etcd.TLSInfo
	EtcdCipherSuites      []string
	EtcdMaxRequestBytes   uint
	EtcdQuotaBackendBytes int64

	TLS *types.TLSOptions
}

Config specifies a Backend configuration.

type EventStoreUpdater

type EventStoreUpdater interface {
	UpdateEventStore(to store.EventStore)
}

EventStoreUpdater offers a way to update an event store to a different implementation in-place.
