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.

Functions

func BootstrapPeerStrings

BootstrapPeerStrings formats a list of AddrInfos as a bootstrap peer list suitable for serialization.

func ConvertAuthSecret added in v0.25.0 

func ConvertAuthSecret(secret string) string

ConvertAuthSecret converts the given secret in the format "type:value" into an HTTP Authorization header value. It can handle 'bearer' and 'basic' as type. If type exists and is not known, an empty string is returned. If type does not exist, 'bearer' type is assumed.

func DataStorePath

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

func DefaultBootstrapPeers 

func DefaultBootstrapPeers() ([]peer.AddrInfo, 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 Filename 

func Filename(configroot, userConfigFile string) (string, error)

Filename returns the configuration file path given a configuration root directory and a user-provided configuration file path argument with the following rules:

  • If the user-provided configuration file path is empty, use the default one.
  • If the configuration root directory is empty, use the default one.
  • If the user-provided configuration file path is only a file name, use the configuration root directory, otherwise use only the user-provided path and ignore the configuration root.

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.
