# s3fs
|
|
|
|
s3fs allows Linux and macOS to mount an S3 bucket via FUSE.
|
|
s3fs preserves the native object format for files, allowing use of other
|
|
tools like [AWS CLI](https://github.com/aws/aws-cli).

## Features
|
|
|
|
* large subset of POSIX including reading/writing files, directories, symlinks, mode, uid/gid, and extended attributes
|
|
* compatible with Amazon S3, and other [S3-based object stores](https://github.com/s3fs-fuse/s3fs-fuse/wiki/Non-Amazon-S3)
|
|
* allows random writes and appends
|
|
* 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
|
|
|
|
Many systems provide pre-built packages:
|
|
|
|
* Amazon Linux via EPEL:
|
|
|
|
```
|
|
sudo amazon-linux-extras install epel
|
|
sudo yum install s3fs-fuse
|
|
```
|
|
|
|
* Arch Linux:
|
|
|
|
```
|
|
sudo pacman -S s3fs-fuse
|
|
```
|
|
|
|
* Debian 9 and Ubuntu 16.04 or newer:
|
|
|
|
```
|
|
sudo apt install s3fs
|
|
```
|
|
|
|
* Fedora 27 or newer:
|
|
|
|
```
|
|
sudo dnf install s3fs-fuse
|
|
```
|
|
|
|
* Gentoo:
|
|
|
|
```
|
|
sudo emerge net-fs/s3fs
|
|
```
|
|
|
|
* RHEL and CentOS 7 or newer through via EPEL:
|
|
|
|
```
|
|
sudo yum install epel-release
|
|
sudo yum install s3fs-fuse
|
|
```
|
|
|
|
* SUSE 12 and openSUSE 42.1 or newer:
|
|
|
|
```
|
|
sudo zypper install s3fs
|
|
```
|
|
|
|
* macOS via [Homebrew](https://brew.sh/):
|
|
|
|
```
|
|
brew install --cask osxfuse
|
|
brew install s3fs
|
|
```
|
|
|
|
Note: Homebrew has deprecated osxfuse and s3fs may not install any more, see
|
|
[#1618](https://github.com/s3fs-fuse/s3fs-fuse/issues/1618).
|
|
|
|
Otherwise consult the [compilation instructions](COMPILATION.md).
|
|
|
|
## Examples
|
|
|
|
s3fs supports the standard
|
|
[AWS credentials file](https://docs.aws.amazon.com/cli/latest/userguide/cli-config-files.html)
|
|
stored in `${HOME}/.aws/credentials`. Alternatively, s3fs supports a custom passwd file.
|
|
|
|
The default location for the s3fs password file can be created:
|
|
|
|
* using a `.passwd-s3fs` file in the users home directory (i.e. `${HOME}/.passwd-s3fs`)
|
|
* using the system-wide `/etc/passwd-s3fs` file
|
|
|
|
Enter your credentials in a file `${HOME}/.passwd-s3fs` and set
|
|
owner-only permissions:
|
|
|
|
```
|
|
echo ACCESS_KEY_ID:SECRET_ACCESS_KEY > ${HOME}/.passwd-s3fs
|
|
chmod 600 ${HOME}/.passwd-s3fs
|
|
```
|
|
|
|
Run s3fs with an existing bucket `mybucket` and directory `/path/to/mountpoint`:
|
|
|
|
```
|
|
s3fs mybucket /path/to/mountpoint -o passwd_file=${HOME}/.passwd-s3fs
|
|
```
|
|
|
|
If you encounter any errors, enable debug output:
|
|
|
|
```
|
|
s3fs mybucket /path/to/mountpoint -o passwd_file=${HOME}/.passwd-s3fs -o dbglevel=info -f -o curldbg
|
|
```
|
|
|
|
You can also mount on boot by entering the following line to `/etc/fstab`:
|
|
|
|
```
|
|
mybucket /path/to/mountpoint fuse.s3fs _netdev,allow_other 0 0
|
|
```
|
|
|
|
If you use s3fs with a non-Amazon S3 implementation, specify the URL and path-style requests:
|
|
|
|
```
|
|
s3fs mybucket /path/to/mountpoint -o passwd_file=${HOME}/.passwd-s3fs -o url=https://url.to.s3/ -o use_path_request_style
|
|
```
|
|
|
|
or(fstab)
|
|
|
|
```
|
|
mybucket /path/to/mountpoint fuse.s3fs _netdev,allow_other,use_path_request_style,url=https://url.to.s3/ 0 0
|
|
```
|
|
|
|
Note: You may also want to create the global credential file first
|
|
|
|
```
|
|
echo ACCESS_KEY_ID:SECRET_ACCESS_KEY > /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 object, optimized with multi-part upload copy
|
|
* metadata operations such as listing directories have poor performance due to network latency
|
|
* non-AWS providers may have [eventual consistency](https://en.wikipedia.org/wiki/Eventual_consistency) so reads can temporarily yield stale data (AWS offers read-after-write consistency [since Dec 2020](https://aws.amazon.com/about-aws/whats-new/2020/12/amazon-s3-now-delivers-strong-read-after-write-consistency-automatically-for-all-applications/))
|
|
* no atomic renames of files or directories
|
|
* no coordination between multiple clients mounting the same bucket
|
|
* no hard links
|
|
* inotify detects only local modifications, not external ones by other clients or tools
|
|
