+# Compilation from source code
+
+These are generic instructions should work on almost any GNU/Linux, macOS, BSD, or similar.
+
+If you want specific instructions for some distributions, check the [wiki](https://github.com/s3fs-fuse/s3fs-fuse/wiki/Installation-Notes).
+
+Keep in mind using the pre-built packages when available.
+
+1. Ensure your system satisfies build and runtime dependencies for:
+
+* fuse >= 2.8.4
+* automake
+* gcc-c++
+* make
+* libcurl
+* libxml2
+* openssl
+* pkg-config (or your OS equivalent)
+
+2. 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
+```

-S3FS is FUSE (File System in User Space) based solution to mount/unmount an Amazon S3 storage buckets and use system commands with S3 just like it was another Hard Disk.
-
-In order to compile s3fs, You'll need the following requirements:
-
-* Kernel-devel packages (or kernel source) installed that is the SAME version of your running kernel
-* LibXML2-devel packages
-* CURL-devel packages (or compile curl from sources at: curl.haxx.se/ use 7.15.X)
-* GCC, GCC-C++
-* pkgconfig
-* FUSE (>= 2.8.4)
-* FUSE Kernel module installed and running (RHEL 4.x/CentOS 4.x users - read below)
-* OpenSSL-devel (0.9.8)
-* Git
-
-If you're using YUM or APT to install those packages, then it might require additional packaging, allow it to be installed.
-
-Downloading & Compiling:
-------------------------
-In order to download s3fs, download from following url:
-https://github.com/s3fs-fuse/s3fs-fuse/archive/master.zip
-Or clone the following command:
-git clone git://github.com/s3fs-fuse/s3fs-fuse.git
-
-Go inside the directory that has been created (s3fs-fuse) and run: ./autogen.sh
-This will generate a number of scripts in the project directory, including a configure script which you should run with: ./configure
-If configure succeeded, you can now run: make. If it didn't, make sure you meet the dependencies above.
-This should compile the code. If everything goes OK, you'll be greated with "ok!" at the end and you'll have a binary file called "s3fs"
-in the src/ directory.
-
-As root (you can use su, su -, sudo) do: "make install" -this will copy the "s3fs" binary to /usr/local/bin.
-
-Congratulations. S3fs is now compiled and installed.
-
-Usage:
-------
-In order to use s3fs, make sure you have the Access Key and the Secret Key handy. (refer to the wiki)
-First, create a directory where to mount the S3 bucket you want to use.
-Example (as root): mkdir -p /mnt/s3
-Then run: s3fs mybucket[:path] /mnt/s3
-
-This will mount your bucket to /mnt/s3. You can do a simple "ls -l /mnt/s3" to see the content of your bucket.
-
-If you want to allow other people access the same bucket in the same machine, you can add "-o allow_other" to read/write/delete content of the bucket.
-
-You can add a fixed mount point in /etc/fstab, here's an example:
-
-s3fs#mybucket /mnt/s3 fuse allow_other 0 0
-
-This will mount upon reboot (or by launching: mount -a) your bucket on your machine.
-If that does not work, probably you should specify with "_netdev" option in fstab.
-
-All other options can be read at: https://github.com/s3fs-fuse/s3fs-fuse/wiki/Fuse-Over-Amazon
-
-Known Issues:
--------------
-s3fs should be working fine with S3 storage. However, There are couple of limitations:
-
-* Currently s3fs could hang the CPU if you have lots of time-outs. This is *NOT* a fault of s3fs but rather libcurl. This happends when you try to copy thousands of files in 1 session, it doesn't happend when you upload hundreds of files or less.
-* CentOS 4.x/RHEL 4.x users - if you use the kernel that shipped with your distribution and didn't upgrade to the latest kernel RedHat/CentOS gives, you might have a problem loading the "fuse" kernel. Please upgrade to the latest kernel (2.6.16 or above) and make sure "fuse" kernel module is compiled and loadable since FUSE requires this kernel module and s3fs requires it as well.
-* Moving/renaming/erasing files takes time since the whole file needs to be accessed first. A workaround could be to use s3fs's cache support with the use_cache option.

+# 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).
+[![Build Status](https://travis-ci.org/s3fs-fuse/s3fs-fuse.svg?branch=master)](https://travis-ci.org/s3fs-fuse/s3fs-fuse)
+
+## 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
+
+Many systems provide pre-built packages:
+
+* Amazon Linux via EPEL:
+
+  ```
+  sudo amazon-linux-extras install epel
+  sudo yum install 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 cask install osxfuse
+  brew install s3fs
+  ```
+
+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=${HOME}/.passwd-s3fs -o dbglevel=info -f -o curldbg
+```
+
+You can also mount on boot by entering the following line to `/etc/fstab`:
+
+```
+s3fs#mybucket /path/to/mountpoint fuse _netdev,allow_other 0 0
+```
+
+or
+
+```
+mybucket /path/to/mountpoint fuse.s3fs _netdev,allow_other 0 0
+```
+
+If you use s3fs with a non-Amazon S3 implementation, specify the URL and path-style requests:
+
+```
+s3fs mybucket /path/to/mountpoint -o passwd_file=${HOME}/.passwd-s3fs -o url=https://url.to.s3/ -o use_path_request_style
+```
+
+or(fstab)
+
+```
+s3fs#mybucket /path/to/mountpoint fuse _netdev,allow_other,use_path_request_style,url=https://url.to.s3/ 0 0
+```
+
+To use IBM IAM Authentication, use the `-o ibm_iam_auth` option, and specify the Service Instance ID and API Key in your credentials file:
+
+```
+echo SERVICEINSTANCEID:APIKEY > /path/to/passwd
+```
+
+The Service Instance ID is only required when using the `-o create_bucket` option.
+
+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 file
+* metadata operations such as listing directories have poor performance due to network latency
+* [eventual consistency](https://en.wikipedia.org/wiki/Eventual_consistency) can temporarily yield stale data([Amazon S3 Data Consistency Model](https://docs.aws.amazon.com/AmazonS3/latest/dev/Introduction.html#ConsistencyModel))
+* 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
+
+## References
+
+* [goofys](https://github.com/kahing/goofys) - similar to s3fs but has better performance and less POSIX compatibility
+* [s3backer](https://github.com/archiecobbs/s3backer) - mount an S3 bucket as a single file
+* [S3Proxy](https://github.com/gaul/s3proxy) - combine with s3fs to mount Backblaze B2, EMC Atmos, Microsoft Azure, and OpenStack Swift buckets
+* [s3ql](https://github.com/s3ql/s3ql/) - similar to s3fs but uses its own object format
+* [YAS3FS](https://github.com/danilop/yas3fs) - similar to s3fs but uses SNS to allow multiple clients to mount a bucket

 .SH DESCRIPTION
 s3fs is a FUSE filesystem that allows you to mount an Amazon S3 bucket as a local filesystem. It stores files natively and transparently in S3 (i.e., you can use other programs to access the same files).
 .SH AUTHENTICATION
+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. Only AWS credentials file format can be used when AWS session token is required.
 The s3fs password file has this format (use this format if you have only one set of credentials):

 .TP
 \fB\-o\fR use_sse (default is disable)
-use Amazon's Server Site Encryption.
-this option can not be specified with use_rrs.
-(can specify use_sse=1 for old version)
+Specify three type Amazon's Server-Site Encryption: SSE-S3, SSE-C or SSE-KMS. SSE-S3 uses Amazon S3-managed encryption keys, SSE-C uses customer-provided encryption keys, and SSE-KMS uses the master key which you manage in AWS KMS.
+You can specify "use_sse" or "use_sse=1" enables SSE-S3 type (use_sse=1 is old type parameter).
+Case of setting SSE-C, you can specify "use_sse=custom", "use_sse=custom:<custom key file path>" or "use_sse=<custom key file path>" (only <custom key file path> specified is old type parameter).
+You can use "c" for short "custom".
+The custom key file must be 600 permission. The file can have some lines, each line is one SSE-C key.
+The first line in file is used as Customer-Provided Encryption Keys for uploading and changing headers etc.
+If there are some keys after first line, those are used downloading object which are encrypted by not first key.
+So that, you can keep all SSE-C keys in file, that is SSE-C key history.
+If you specify "custom" ("c") without file path, you need to set custom key by load_sse_c option or AWSSSECKEYS environment. (AWSSSECKEYS environment has some SSE-C keys with ":" separator.)
+This option is used to decide the SSE type.
+So that if you do not want to encrypt a object at uploading, but you need to decrypt encrypted object at downloading, you can use load_sse_c option instead of this option.
+For setting SSE-KMS, specify "use_sse=kmsid" or "use_sse=kmsid:<kms id>".
+You can use "k" for short "kmsid".
+If you san specify SSE-KMS type with your <kms id> in AWS KMS, you can set it after "kmsid:" (or "k:").
+If you specify only "kmsid" ("k"), you need to set AWSSSEKMSID environment which value is <kms id>.
+You must be careful about that you can not use the KMS id which is not same EC2 region.
+.TP
+\fB\-o\fR load_sse_c - specify SSE-C keys
+Specify the custom-provided encryption keys file path for decrypting at downloading.

+s3fs needs redundant communication to support all these directory types.
+The object as the directory created by s3fs is "dir/".
+By restricting s3fs to recognize only "dir/" as a directory, communication traffic can be reduced.
+This option is used to give this restriction to s3fs.
+However, if there is a directory object other than "dir/" in the bucket, specifying this option is not recommended.

-Maximum file size=64GB (limited by s3fs, not Amazon).
+The maximum size of objects that s3fs can handle depends on Amazon S3. For example, up to 5 GB when using single PUT API. And up to 5 TB is supported when Multipart Upload API is used.
 .TP
 If enabled via the "use_cache" option, s3fs automatically maintains a local cache of files in the folder specified by use_cache. Whenever s3fs needs to read or write a file on S3, it first downloads the entire file locally to the folder specified by use_cache and operates on it. When fuse_release() is called, s3fs will re-upload the file to S3 if it has been changed. s3fs uses md5 checksums to minimize downloads from S3.
 .TP
@@ -187,6 +361,8 @@ The folder specified by use_cache is just a local cache. It can be deleted at an
 Local file caching works by calculating and comparing md5 checksums (ETag HTTP header).
 .TP
 s3fs leverages /etc/mime.types to "guess" the "correct" content-type based on file name extension. This means that you can copy a website to S3 and serve it up directly from S3 with correct content-types!

 .SH BUGS
 Due to S3's "eventual consistency" limitations, file creation can and will occasionally fail. Even after a successful create, subsequent reads can fail for an indeterminate time, even after one or more successful reads. Create and read enough files and you will eventually encounter this failure. This is not a flaw in s3fs and it is not something a FUSE wrapper like s3fs can work around. The retries option does not address this issue. Your application must either tolerate or compensate for these failures, for example by retrying creates or reads.
