s3fs

s3fs allows Linux and Mac OS X to mount an S3 bucket via FUSE. s3fs preserves the native object format for files, allowing use of other tools like s3cmd.
Build Status

Features

  • large subset of POSIX including reading/writing files, directories, symlinks, mode, uid/gid, and extended attributes
  • compatible with Amazon S3, Google Cloud Storage, and other S3-based object stores
  • large files via multi-part upload
  • renames via server-side copy
  • optional server-side encryption
  • data integrity via MD5 hashes
  • in-memory metadata caching
  • local disk data caching
  • user-specified regions, including Amazon GovCloud
  • authenticate via v2 or v4 signatures

Installation

  • On Linux, ensure you have all the dependencies:

On Ubuntu 14.04:

sudo apt-get install automake autotools-dev fuse g++ git libcurl4-gnutls-dev libfuse-dev libssl-dev libxml2-dev make pkg-config

On CentOS 7:

sudo yum install automake fuse fuse-devel gcc-c++ git libcurl-devel libxml2-devel make openssl-devel

Then compile from master via the following commands:

git clone https://github.com/s3fs-fuse/s3fs-fuse.git
cd s3fs-fuse
./autogen.sh
./configure
make
sudo make install
$ brew cask install osxfuse
$ brew install s3fs

Examples

Enter your S3 identity and credential in a file /path/to/passwd and set owner-only permissions:

echo MYIDENTITY:MYCREDENTIAL > /path/to/passwd
chmod 600 /path/to/passwd

Run s3fs with an existing bucket mybucket and directory /path/to/mountpoint:

s3fs mybucket /path/to/mountpoint -o passwd_file=/path/to/passwd

If you encounter any errors, enable debug output:

s3fs mybucket /path/to/mountpoint -o passwd_file=/path/to/passwd -dbglevel=info -f -o curldbg

You can also mount on boot by entering the following line to /etc/fstab:

s3fs#mybucket /path/to/mountpoint fuse _netdev,allow_other 0 0

or

mybucket /path/to/mountpoint fuse.s3fs _netdev,allow_other 0 0

If you use s3fs with a non-Amazon S3 implementation, specify the URL and path-style requests:

s3fs mybucket /path/to/mountpoint -o passwd_file=/path/to/passwd -o url=http://url.to.s3/ -o use_path_request_style

or(fstab)

s3fs#mybucket /path/to/mountpoint fuse _netdev,allow_other,use_path_request_style,url=http://url.to.s3/ 0 0

Note: You may also want to create the global credential file first

echo MYIDENTITY:MYCREDENTIAL > /etc/passwd-s3fs
chmod 600 /etc/passwd-s3fs

Note2: You may also need to make sure netfs service is start on boot

Limitations

Generally S3 cannot offer the same performance or semantics as a local file system. More specifically:

  • random writes or appends to files require rewriting the entire file
  • metadata operations such as listing directories have poor performance due to network latency
  • eventual consistency can temporarily yield stale data(Amazon S3 Data Consistency Model)
  • no atomic renames of files or directories
  • no coordination between multiple clients mounting the same bucket
  • no hard links

References

  • goofys - similar to s3fs but has better performance and less POSIX compatibility
  • s3backer - mount an S3 bucket as a single file
  • s3fs-python - an older and less complete implementation written in Python
  • S3Proxy - combine with s3fs to mount EMC Atmos, Microsoft Azure, and OpenStack Swift buckets
  • s3ql - similar to s3fs but uses its own object format
  • YAS3FS - similar to s3fs but uses SNS to allow multiple clients to mount a bucket
