Kubo: IPFS Implementation in GO

The first implementation of IPFS.

What is Kubo?

Kubo was the first IPFS implementation and is the most widely used one today. Implementing the Interplanetary Filesystem - the Web3 standard for content-addressing, interoperable with HTTP. Thus powered by IPLD's data models and the libp2p for network communication. Kubo is written in Go.

What is IPFS?

IPFS is a global, versioned, peer-to-peer filesystem. It combines good ideas from previous systems such as Git, BitTorrent, Kademlia, SFS, and the Web. It is like a single BitTorrent swarm, exchanging git objects. IPFS provides an interface as simple as the HTTP web, but with permanence built-in. You can also mount the world at /ipfs.

Security Issues

Please follow SECURITY.md.

Minimal System Requirements

IPFS can run on most Linux, macOS, and Windows systems. We recommend running it on a machine with at least 4 GB of RAM and 2 CPU cores (kubo is highly parallel). On systems with less memory, it may not be completely stable, and you run on your own risk.

Install

The canonical download instructions for IPFS are over at: https://docs.ipfs.tech/install/. It is highly recommended you follow those instructions if you are not interested in working on IPFS development.

Docker

Official images are published at https://hub.docker.com/r/ipfs/kubo/:

More info on how to run Kubo (go-ipfs) inside Docker can be found here.

Official prebuilt binaries

The official binaries are published at https://dist.ipfs.tech#kubo:

From there:

  • Click the blue "Download Kubo" on the right side of the page.
  • Open/extract the archive.
  • Move kubo (ipfs) to your path (install.sh can do it for you).

If you are unable to access dist.ipfs.tech, you can also download kubo (go-ipfs) from:

Updating Using ipfs-update

IPFS has an updating tool that can be accessed through ipfs update. The tool is not installed alongside IPFS in order to keep that logic independent of the main codebase. To install ipfs-update tool, download it here.

Downloading builds using IPFS

List the available versions of Kubo (go-ipfs) implementation:

$ ipfs cat /ipns/dist.ipfs.tech/kubo/versions

Then, to view available builds for a version from the previous command ($VERSION):

$ ipfs ls /ipns/dist.ipfs.tech/kubo/$VERSION

To download a given build of a version:

$ ipfs get /ipns/dist.ipfs.tech/kubo/$VERSION/kubo_$VERSION_darwin-386.tar.gz    # darwin 32-bit build
$ ipfs get /ipns/dist.ipfs.tech/kubo/$VERSION/kubo_$VERSION_darwin-amd64.tar.gz  # darwin 64-bit build
$ ipfs get /ipns/dist.ipfs.tech/kubo/$VERSION/kubo_$VERSION_freebsd-amd64.tar.gz # freebsd 64-bit build
$ ipfs get /ipns/dist.ipfs.tech/kubo/$VERSION/kubo_$VERSION_linux-386.tar.gz     # linux 32-bit build
$ ipfs get /ipns/dist.ipfs.tech/kubo/$VERSION/kubo_$VERSION_linux-amd64.tar.gz   # linux 64-bit build
$ ipfs get /ipns/dist.ipfs.tech/kubo/$VERSION/kubo_$VERSION_linux-arm.tar.gz     # linux arm build
$ ipfs get /ipns/dist.ipfs.tech/kubo/$VERSION/kubo_$VERSION_windows-amd64.zip    # windows 64-bit build
Unofficial Linux packages

  • ArchLinux
  • Nix
  • Solus
  • openSUSE
  • Guix
  • Snap

Arch Linux 

# pacman -S kubo

Nix

With the purely functional package manager Nix you can install kubo (go-ipfs) like this:

$ nix-env -i kubo

You can also install the Package by using its attribute name, which is also kubo.

Solus

Package for Solus

$ sudo eopkg install kubo

You can also install it through the Solus software center.

openSUSE

Community Package for go-ipfs

Guix

Community Package for go-ipfs is no out-of-date.

Snap

No longer supported, see rationale in kubo#8688.

Unofficial Windows packages

  • Chocolatey
  • Scoop

Chocolatey

No longer supported, see rationale in kubo#9341.

Scoop

Scoop provides kubo as kubo in its 'extras' bucket.

PS> scoop bucket add extras
PS> scoop install kubo
Unofficial macOS packages

  • MacPorts
  • Nix
  • Homebrew

MacPorts

The package ipfs currently points to kubo (go-ipfs) and is being maintained.

$ sudo port install ipfs
Nix

In macOS you can use the purely functional package manager Nix:

$ nix-env -i kubo

You can also install the Package by using its attribute name, which is also kubo.

Homebrew

A Homebrew formula ipfs is maintained too.

$ brew install --formula ipfs
Build from Source

kubo's build system requires Go and some standard POSIX build tools:

  • GNU make
  • Git
  • GCC (or some other go compatible C Compiler) (optional)

To build without GCC, build with CGO_ENABLED=0 (e.g., make build CGO_ENABLED=0).

Install Go

If you need to update: Download latest version of Go.

You'll need to add Go's bin directories to your $PATH environment variable e.g., by adding these lines to your /etc/profile (for a system-wide installation) or $HOME/.profile:

export PATH=$PATH:/usr/local/go/bin
export PATH=$PATH:$GOPATH/bin

(If you run into trouble, see the Go install instructions).

Download and Compile IPFS 

$ git clone https://github.com/ipfs/kubo.git



$ cd kubo
$ make install

Alternatively, you can run make build to build the go-ipfs binary (storing it in cmd/ipfs/ipfs) without installing it.

NOTE: If you get an error along the lines of "fatal error: stdlib.h: No such file or directory", you're missing a C compiler. Either re-run make with CGO_ENABLED=0 or install GCC.

Cross Compiling

Compiling for a different platform is as simple as running:

make build GOOS=myTargetOS GOARCH=myTargetArchitecture
Troubleshooting

  • Separate instructions are available for building on Windows.
  • git is required in order for go get to fetch all dependencies.
  • Package managers often contain out-of-date golang packages. Ensure that go version reports at least 1.10. See above for how to install go.
  • If you are interested in development, please install the development dependencies as well.
  • Shell command completions can be generated with one of the ipfs commands completion subcommands. Read docs/command-completion.md to learn more.
  • See the misc folder for how to connect IPFS to systemd or whatever init system your distro uses.

Getting Started Usage

To start using IPFS, you must first initialize IPFS's config files on your system, this is done with ipfs init. See ipfs init --help for information on the optional arguments it takes. After initialization is complete, you can use ipfs mount, ipfs add and any of the other commands to explore!

Some things to try

Basic proof of 'ipfs working' locally:

echo "hello world" > hello
ipfs add hello



This should output a hash string that looks something like:



QmT78zSuBmuS4z925WZfrqQ1qHaJ56DQaTfyMUF7F8ff5o



ipfs cat <that hash>
HTTP/RPC clients

For programmatic interaction with Kubo, see our list of HTTP/RPC clients.

Troubleshooting

If you have previously installed IPFS before and you are running into problems getting a newer version to work, try deleting (or backing up somewhere else) your IPFS config directory (~/.ipfs by default) and rerunning ipfs init. This will reinitialize the config file to its defaults and clear out the local datastore of any bad entries.

Packages

Development

Some places to get you started on the codebase:

Map of Implemented Subsystems

WIP: This is a high-level architecture diagram of the various sub-systems of this specific implementation. To be updated with how they interact. Anyone who has suggestions is welcome to comment here on how we can improve this!

CLI, HTTP-API, Architecture Diagram

Origin

Description: Dotted means "likely going away". The "Legacy" parts are thin wrappers around some commands to translate between the new system and the old system. The grayed-out parts on the "daemon" diagram are there to show that the code is all the same, it's just that we turn some pieces on and some pieces off depending on whether we're running on the client or the server.

Testing 

make test
Development Dependencies

If you make changes to the protocol buffers, you will need to install the protoc compiler.
