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.

Featureset

• Runs an IPFS-Node as a network service that is part of LAN and WAN DHT
• HTTP Gateway (/ipfs and /ipns) functionality for trusted and trustless content retrieval
• HTTP Routing V1 (/routing/v1) client and server implementation for delegated routing lookups
• HTTP Kubo RPC API (/api/v0) to access and control the daemon
• Command Line Interface based on (/api/v0) RPC API
• WebUI to manage the Kubo node
• Content blocking support for operators of public nodes

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/:

• 🟢 Releases
  • latest and release tags always point at the latest stable release
  • vN.N.N points at a specific release tag
  • These are production grade images.
• 🟠 We also provide experimental developer builds
  • master-latest always points at the HEAD of the master branch
  • master-YYYY-DD-MM-GITSHA points at a specific commit from the master branch
  • These tags are used by developers for internal testing, not intended for end users or production use.

$ docker pull ipfs/kubo:latest
$ docker run --rm -it --net=host ipfs/kubo:latest

To customize your node, pass necessary config via -e or by mounting scripts in the /container-init.d.

Learn more at https://docs.ipfs.tech/install/run-ipfs-inside-docker/

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:

• this project's GitHub releases page
• /ipns/dist.ipfs.tech at dweb.link gateway

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
