IPFS implementation in Go
IPFS is a global, versioned, peer-to-peer filesystem. It combines good ideas from 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
- Getting Started
The IPFS protocol and its implementations are still in heavy development. This means that there may be problems in our protocols, or there may be mistakes in our implementations. And -- though IPFS is not production-ready yet -- many people are already running nodes in their machines. So we take security vulnerabilities very seriously. If you discover a security issue, please bring it to our attention right away!
If you find a vulnerability that may affect live deployments -- for example, by exposing a remote execution exploit -- please send your report privately to email@example.com. Please DO NOT file a public issue.
If the issue is a protocol weakness that cannot be immediately exploited or something not yet deployed, just discuss it openly.
The canonical download instructions for IPFS are over at: http://ipfs.io/docs/install/. It is highly suggested you follow those instructions if you are not interested in working on IPFS development.
Install prebuilt packages
We host prebuilt binaries over at our distributions page.
- Click the blue "Download go-ipfs" on the right side of the page.
- Open/extract the archive.
ipfsto your path (
install.shcan do it for you).
Build from Source
First, you'll need Go. If you don't have it: Download Go 1.5.2+. Go 1.6 is not yet supported.
You'll need to add Go's bin directories to your
$PATH environment variable e.g., by adding these lines to your
/etc/profile (for a system-wide installation) or
export PATH=$PATH:/usr/local/go/bin export PATH=$PATH:$GOPATH/bin
(If you run into trouble, see the Go install instructions).
Download + Compile IPFS
go-ipfs without installing:
$ go get -d github.com/ipfs/go-ipfs $ cd $GOPATH/src/github.com/ipfs/go-ipfs
If you don't already have them on your system, install
$ make toolkit_upgrade
$ make install
gitis required in order for
go getto fetch all dependencies.
- Package managers often contain out-of-date
golangpackages. Ensure that
go versionreports at least 1.5.2. See above for how to install go.
- If you are interested in development, please install the development dependencies as well.
- WARNING: Older versions of OSX FUSE (for Mac OS X) can cause kernel panics when mounting! We strongly recommend you use the latest version of OSX FUSE. (See https://github.com/ipfs/go-ipfs/issues/177)
- For more details on setting up FUSE (so that you can mount the filesystem), see the docs folder.
- Shell command completion is available in
misc/completion/ipfs-completion.bash. Read docs/command-completion.md to learn how to install it.
- See the init examples for how to connect IPFS to systemd or whatever init system your distro uses.
If you make changes to the protocol buffers, you will need to install the protoc compiler.
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, either download it here
or install it from source with
go get -u github.com/ipfs/ipfs-update.

By default, the repo is located at ~/.ipfs. To change the repo location, set the $IPFS_PATH environment variable: export IPFS_PATH=/path/to/ipfsrepo
See also: http://ipfs.io/docs/getting-started/
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 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>
An IPFS docker image is hosted at hub.docker.com/r/ipfs/go-ipfs.
To make files visible inside the container you need to mount a host directory
-v option to docker. Choose a directory that you want to use to
import/export files from IPFS. You should also choose a directory to store
IPFS files that will persist when you restart the container.
export ipfs_staging=</absolute/path/to/somewhere/> export ipfs_data=</absolute/path/to/somewhere_else/>
Make sure docker can access these folders:
sudo chmod -R 777 /absolute/path/to/somewhere/ sudo chmod -R 777 /absolute/path/to/somewhere_else/
Start a container running ipfs and expose ports 4001, 5001 and 8080:
docker run -d --name ipfs_host -v $ipfs_staging:/export -v $ipfs_data:/data/ipfs -p 8080:8080 -p 4001:4001 -p 5001:5001 ipfs/go-ipfs:latest
Watch the ipfs log:
docker logs -f ipfs_host
Wait for ipfs to start. ipfs is running when you see:
Gateway (readonly) server listening on /ip4/0.0.0.0/tcp/8080
You can now stop watching the log.
Run ipfs commands:
docker exec ipfs_host ipfs <args...>
For example: connect to peers
docker exec ipfs_host ipfs swarm peers
cp -r <something> $ipfs_staging docker exec ipfs_host ipfs add -r /export/<something>
Stop the running container:
docker stop ipfs_host
Docker usage with VirtualBox/boot2docker (OSX and Windows)
Since docker is running in the boot2docker VM, you need to forward relevant ports from the VM to your host for IPFS to act normally. This is accomplished with the following command:
boot2docker ssh -L 5001:localhost:5001 -L 4001:localhost:4001 -L 8080:localhost:8080 -fN
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
This will reinitialize the config file to its defaults and clear out the local
datastore of any bad entries.
For any other problems, check the issues list and if you dont see your problem there, either come talk to us on irc (freenode #ipfs) or file an issue of your own!

An IPFS alpha version has been released in February 2015. Things left to be done are all marked as issues.
