Linux brings the advantage of having a large number of open source solutions to access the Exoscale Object Storage. One of these is s3fs.


The Object Storage is not a disk drive! Using it as a storage backend with a database or similar from multiple machines may have unintended consequences.


As prerequisite for the following documentation, you’ll have to:


s3fs is supplied as a package in most Linux distributions, which makes the installation simple. Execute the following commands on a root console.


s3fs could not show the file sizes before version 1.84. If you see only 0-byte files please update your s3fs version.

Ubuntu Linux 16.04 or higher, Debian Linux 9 or higher

apt install s3fs

RHEL and CentOS 7 or newer, using EPEL:

yum install epel-release
yum install s3fs-fuse

SUSE 12 and openSUSE 42.1 or newer:

zypper install s3fs

Storing your access key

Save your access key as the root user:

echo API-KEY-HERE:API-SECRET-HERE > /root/.passwd-s3fs

Also change its permissions:

chmod 0600 /root/.passwd-s3fs

Create a folder

To mount the bucket you will have to create an empty folder. This could be located in /mnt/sos:

mkdir /mnt/sos

Mount by hand

Before we add the mount point permanently you can try it by hand:

s3fs BUCKET-NAME-HERE /TARGET/DIRECTORY -o use_path_request_style -o url=

So, for example:

s3fs my-testbucket /mnt/sos -o use_path_request_style -o url=

Automated mount

To mount the object storage automatically at system start you will have to edit the /etc/fstab file.


This file is required for a correct system start. If you make a mistake your system may not boot. Make sure to read up on the restore procedure and create a backup (e.g. a snapshot) before you proceed.

Insert the following line followed by a new line character:

s3fs#BUCKET-NAME /TARGET/DIRECTORY fuse _netdev,allow_other,use_path_request_style,url= 0 0

So, for example:

s3fs#my-testbucket /mnt/sos fuse _netdev,allow_other,use_path_request_style,url= 0 0

Now you can mount the folder:

mount -a
