This client allows you to mount KBFS as a proper filesystem at some
mountpoint on your local device (by default,
communicates locally with the Keybase service, and remotely with three
types of KBFS servers (block servers, metadata servers, and key
The code is organized as follows:
- dokan: Helper code for running Dokan filesystems on Windows.
- env: Code to implement libkbfs.Context in terms of libkb.
- fsrpc: RPC interfaces that connected clients can call in KBFS, to do certain operations, such as listing files.
- ioutil: Helper functions for I/O.
- kbfsblock: Types and functions to work with KBFS blocks.
- kbfscodec: Interfaces and types used for serialization in KBFS.
- kbfscrypto: KBFS-specific cryptographic types and functions.
- kbfsdokan: The main executable for running KBFS on Windows.
- kbfsfuse: The main executable for running KBFS on Linux and OS X.
- kbfshash: An implementation of the KBFS hash spec.
- kbfsmd: Types and functions to work with KBFS TLF metadata.
- kbfssync: KBFS-specific synchronization primitives.
- kbfstool: A thin command line utility for interacting with KBFS without using a filesystem mountpoint.
- libdokan: Library code gluing together KBFS and the Dokan protocol.
- libfs: Common library code useful to any filesystem presentation layer for KBFS.
- libfuse: Library code gluing together KBFS and the FUSE protocol.
- libkbfs: The core logic for KBFS.
- metricsutil: Helper code for collecting metrics.
- test: A test harness with a domain-specific test language and tests in that language.
- tlf: Code and structures for top-level folders (TLFs).
- vendor: Vendored versions of the open-source libraries used by KBFS.
KBFS currently works on both Linux (at least Debian, Ubuntu and Arch), OS X, and Windows. It is approaching release ready, though currently it is still in alpha. There may still be bugs, so please keep backups of any important data you store in KBFS. Currently our pre-built packages are available by invitation only.
KBFS depends in part on the following awesome technologies to present a mountpoint on your device:
See our vendor directory for a complete list of open source packages KBFS uses.
Currently, our server implementations are not open source.
To run from source against production KBFS servers
On Linux or OS X:
- Go 1.7 or higher.
- A running Keybase client service (see instructions).
- On OS X, you may have to install FUSE yourself.
- You may need to pass the
kbfsfuseif you install FUSE yourself.
- You may need to pass the
- Then, mount KBFS at
cd kbfsfuse go install mkdir -p /keybase && sudo chown $USER /keybase KEYBASE_RUN_MODE=prod kbfsfuse /keybase
Note that our pre-built packages for OS X include a branded version of FUSE for OS X, to ensure that it doesn't conflict with other local FUSE installations. It is still open source -- see here to see how we build it.
See our kbfsdokan documentation.
There are instructions for getting KBFS running on FreeBSD here. This is a user-supported effort, which is not officially supported by the Keybase team at the moment.
To run from source against local in-memory servers
kbfsfuse -bserver=memory -mdserver=memory -localuser strib /keybase
instead you want to save your data to local disk.)
Now you can do cool stuff like:
ls /keybase/private/strib echo blahblah > /keybase/private/strib/foo ls /keybase/private/strib,max
(Note that "localuser" mode has only four hard-coded users to play with: "strib", "max", "chris", and "fred".)
We require all code to pass
govet. You can install our
precommit hooks to make sure your code passes
go get golang.org/x/tools/cmd/vet ln -s $GOPATH/src/github.com/keybase/client/git-hooks/pre-commit $GOPATH/src/github.com/keybase/kbfs/.git/hooks/pre-commit
Though it doesn't happen automatically, we also expect your code to be as "lint-free" as possible. Running golint is easy from the top-level kbfs directory:
go get -u github.com/golang/lint/golint make lint
KBFS vendors all of its dependencies into the local
directory. To add or update dependencies, use the
govendor tool, as
go install github.com/kardianos/govendor govendor add github.com/foo/bar # or `govendor update` git add --all vendor
go test -i ./... go test ./...
If you change anything in interfaces.go, you will have to regenerate the mock interfaces used by the tests:
cd libkbfs ./gen_mocks.sh
(Right now the mocks are checked into the repo; this isn't ideal and we should probably change it.)
