The go-ipfs config file

The go-ipfs config file is a json document. It is read once at node instantiation, either for an offline command, or when starting the daemon. Commands that execute on a running daemon do not read the config file at runtime.

Profiles

Configuration profiles allow to tweak configuration quickly. Profiles can be applied with --profile flag to ipfs init or with ipfs config profile apply command. When a profile is applied a backup of the configuration file will be created in $IPFS_PATH

Available profiles:

  • server

    Recommended for nodes with public IPv4 address (servers, VPSes, etc.), disables host and content discovery in local networks.

  • local-discovery

    Sets default values to fields affected by server profile, enables discovery in local networks.

  • test

    Reduces external interference, useful for running ipfs in test environments. Note that with these settings node won't be able to talk to the rest of the network without manual bootstrap.

  • default-networking

    Restores default network settings. Inverse profile of the test profile.

  • badgerds

    Replaces default datastore configuration with experimental badger datastore. If you apply this profile after ipfs init, you will need to convert your datastore to the new configuration. You can do this using ipfs-ds-convert

    WARNING: badger datastore is experimental. Make sure to backup your data frequently.

  • default-datastore

    Restores default datastore configuration.

  • lowpower

    Reduces daemon overhead on the system. May affect node functionality, performance of content discovery and data fetching may be degraded.

Table of Contents

Addresses

Contains information about various listener addresses to be used by this node.

  • API Multiaddr describing the address to serve the local HTTP API on.

Default: /ip4/127.0.0.1/tcp/5001

  • Gateway Multiaddr describing the address to serve the local gateway on.

Default: /ip4/127.0.0.1/tcp/8080

  • Swarm Array of multiaddrs describing which addresses to listen on for p2p swarm connections.

Default:

[
  "/ip4/0.0.0.0/tcp/4001",
  "/ip6/::/tcp/4001"
]
  • Announce If non-empty, this array specifies the swarm addresses to announce to the network. If empty, the daemon will announce inferred swarm addresses.

Default: []

  • NoAnnounce Array of swarm addresses not to announce to the network.

Default: []

API

Contains information used by the API gateway.

  • HTTPHeaders Map of HTTP headers to set on responses from the API HTTP server.

Example:

{
	"Foo": ["bar"]
}

Default: null

Bootstrap

Bootstrap is an array of multiaddrs of trusted nodes to connect to in order to initiate a connection to the network.

Default: The ipfs.io bootstrap nodes

Datastore

Contains information related to the construction and operation of the on-disk storage system.

  • StorageMax A soft upper limit for the size of the ipfs repository's datastore. With StorageGCWatermark, is used to calculate whether to trigger a gc run (only if --enable-gc flag is set).

Default: 10GB

  • StorageGCWatermark The percentage of the StorageMax value at which a garbage collection will be triggered automatically if the daemon was run with automatic gc enabled (that option defaults to false currently).

Default: 90

  • GCPeriod A time duration specifying how frequently to run a garbage collection. Only used if automatic gc is enabled.

Default: 1h

  • HashOnRead A boolean value. If set to true, all block reads from disk will be hashed and verified. This will cause increased CPU utilization.

  • BloomFilterSize A number representing the size in bytes of the blockstore's bloom filter. A value of zero represents the feature being disabled.

Default: 0

  • Spec Spec defines the structure of the ipfs datastore. It is a composable structure, where each datastore is represented by a json object. Datastores can wrap other datastores to provide extra functionality (eg metrics, logging, or caching).

This can be changed manually, however, if you make any changes that require a different on-disk structure, you will need to run the ipfs-ds-convert tool to migrate data into the new structures.

For more information on possible values for this configuration option, see docs/datastores.md

Default:

{
  "mounts": [
	{
	  "child": {
		"path": "blocks",
		"shardFunc": "/repo/flatfs/shard/v1/next-to-last/2",
		"sync": true,
		"type": "flatfs"
	  },
	  "mountpoint": "/blocks",
	  "prefix": "flatfs.datastore",
	  "type": "measure"
	},
	{
	  "child": {
		"compression": "none",
		"path": "datastore",
		"type": "levelds"
	  },
	  "mountpoint": "/",
	  "prefix": "leveldb.datastore",
	  "type": "measure"
	}
  ],
  "type": "mount"
}

Discovery

Contains options for configuring ipfs node discovery mechanisms.

  • MDNS Options for multicast dns peer discovery.

    • Enabled A boolean value for whether or not mdns should be active.

Default: true

  • Interval A number of seconds to wait between discovery checks.

  • Routing Content routing mode. Can be overridden with daemon --routing flag. Valid modes are:

    • dht (default)
    • dhtclient
    • none

Gateway

Options for the HTTP gateway.

  • HTTPHeaders Headers to set on gateway responses.

Default:

{
	"Access-Control-Allow-Headers": [
		"X-Requested-With"
	],
	"Access-Control-Allow-Methods": [
		"GET"
	],
	"Access-Control-Allow-Origin": [
		"*"
	]
}
  • RootRedirect A url to redirect requests for / to.

Default: ""

  • Writeable A boolean to configure whether the gateway is writeable or not.

Default: false

  • PathPrefixes TODO

Default: []

Identity

  • PeerID The unique PKI identity label for this configs peer. Set on init and never read, its merely here for convenience. Ipfs will always generate the peerID from its keypair at runtime.

  • PrivKey The base64 encoded protobuf describing (and containing) the nodes private key.

Ipns

  • RepublishPeriod A time duration specifying how frequently to republish ipns records to ensure they stay fresh on the network. If unset, we default to 4 hours.

  • RecordLifetime A time duration specifying the value to set on ipns records for their validity lifetime. If unset, we default to 24 hours.

  • ResolveCacheSize The number of entries to store in an LRU cache of resolved ipns entries. Entries will be kept cached until their lifetime is expired.

Default: 128

Mounts

FUSE mount point configuration options.

  • IPFS Mountpoint for /ipfs/.

  • IPNS Mountpoint for /ipns/.

  • FuseAllowOther Sets the FUSE allow other option on the mountpoint.

Reprovider

  • Interval Sets the time between rounds of reproviding local content to the routing system. If unset, it defaults to 12 hours. If set to the value "0" it will disable content reproviding.

Note: disabling content reproviding will result in other nodes on the network not being able to discover that you have the objects that you have. If you want to have this disabled and keep the network aware of what you have, you must manually announce your content periodically.

  • Strategy Tells reprovider what should be announced. Valid strategies are:
    • "all" (default) - announce all stored data
    • "pinned" - only announce pinned data
    • "roots" - only announce directly pinned keys and root keys of recursive pins

Swarm

Options for configuring the swarm.

  • AddrFilters An array of address filters (multiaddr netmasks) to filter dials to. See this issue for more information.

  • DisableBandwidthMetrics A boolean value that when set to true, will cause ipfs to not keep track of bandwidth metrics. Disabling bandwidth metrics can lead to a slight performance improvement, as well as a reduction in memory usage.

  • DisableNatPortMap Disable NAT discovery.

  • DisableRelay Disables the p2p-circuit relay transport.

  • EnableRelayHop Enables HOP relay for the node. If this is enabled, the node will act as an intermediate (Hop Relay) node in relay circuits for connected peers.

ConnMgr

Connection manager configuration.

  • Type Sets the type of connection manager to use, options are: "none" and "basic".

  • LowWater LowWater is the minimum number of connections to maintain.

  • HighWater HighWater is the number of connections that, when exceeded, will trigger a connection GC operation.

  • GracePeriod GracePeriod is a time duration that new connections are immune from being closed by the connection manager.
