DefaultBootstrapAddresses are the hardcoded bootstrap addresses for IPFS. they are nodes run by the IPFS team. docs on these later. As with all p2p networks, bootstrap is an important security concern.

NOTE: This is here -- and not inside cmd/ipfs/init.go -- because of an import dependency issue. TODO: move this into a config/default/ package.

var ErrInvalidPeerAddr = errors.New("invalid peer address")

ErrInvalidPeerAddr signals an address is not a valid peer address.

Functions

func BootstrapPeerStrings 

func BootstrapPeerStrings(bps []BootstrapPeer) []string

func DataStorePath 

func DataStorePath(configroot string) (string, error)

DataStorePath returns the default data store path given a configuration root (set an empty string to have the default configuration root)

func Filename 

func Filename(configroot string) (string, error)

Filename returns the configuration file path given a configuration root directory. If the configuration root directory is empty, use the default one

func HumanOutput 

func HumanOutput(value interface{}) ([]byte, error)

HumanOutput gets a config value ready for printing

func Marshal 

func Marshal(value interface{}) ([]byte, error)

Marshal configuration with JSON

func Path 

func Path(configroot, extension string) (string, error)

Path returns the path `extension` relative to the configuration root. If an empty string is provided for `configroot`, the default root is used.

func PathRoot 

func PathRoot() (string, error)

PathRoot returns the default configuration root directory

func ToMap 

func ToMap(conf *Config) (map[string]interface{}, error)

Types

type API added in v0.3.6 

type API struct {
	HTTPHeaders map[string][]string // HTTP headers to return with the API.
}

type Addresses 

type Addresses struct {
	Swarm      []string // addresses for the swarm to listen on
	Announce   []string // swarm addresses to announce to the network
	NoAnnounce []string // swarm addresses not to announce to the network

}

Addresses stores the (string) multiaddr addresses for the node.

type BootstrapPeer 

type BootstrapPeer iaddr.IPFSAddr

BootstrapPeer is a peer used to bootstrap the network.

func DefaultBootstrapPeers 

func DefaultBootstrapPeers() ([]BootstrapPeer, error)

DefaultBootstrapPeers returns the (parsed) set of default bootstrap peers. if it fails, it returns a meaningful error for the user. This is here (and not inside cmd/ipfs/init) because of module dependency problems.

func ParseBootstrapPeer 

func ParseBootstrapPeer(addr string) (BootstrapPeer, error)

func ParseBootstrapPeers 

func ParseBootstrapPeers(addrs []string) ([]BootstrapPeer, error)

type Config 

type Config struct {
	Identity  Identity  // local node's peer identity
