Mounting your OVH Object Storage Bucket as a File System

Introduction

In my previous articles, i have explained how to mount the Object Storage Bucket as a File System on Flexible Engine’s ECS Instances.

• Flexible Engine Python SDK.
• Using the s3fs-fuse project.

In this article, i will be using the s3fs-fuse project along with the Swift S3 API to mount OVH Object storage bucket on an OVH instance.

What is Object Storage

Object Storage allows you to store a large amount of unstructured data in a highly scalable manner using REST APIs.

The benefits behind using such service are :

Durability : data is kept safe on the cloud.

Availability : data is available and accessible remotely through REST APIs.

Scalability : such service is meant to store large amount of data.

Security : data can be encrypted when stored and while it is in transit.

Object Storage Use Cases :

• Backups : storage for backup files, database dumps, and log files.

Setting up the Swift S3 API

First, you need to get your openrc.sh file from your OVH platform. Then, you need to install the aws client :

sudo apt-get update 
sudo apt-get upgrade
pip3 install awscli awscli-plugin-endpoint
sudo apt-get install awscli

Next, you need to configure the aws client :

sudo mkdir .aws
nano .aws/config

Based on the configuration described in the openrc.sh file , add the following lines in the config file :

[plugins]
endpoint = awscli_plugin_endpoint
[profile default]
aws_access_key_id = put-here-access-key
aws_secret_access_key = put-here-secret-key
region = gra (put-here-your-region, gra is just an example)
s3 =
endpoint_url = https://s3.gra.cloud.ovh.net
signature_version = s3v4
addressing_style = virtual
s3api =
endpoint_url = https://s3.gra.cloud.ovh.net

Once done, you can :

• List your available buckets:

aws --profile default s3 ls

• Create a bucket:

aws --profile default s3 mb s3://bucket

Note : S3 no longer supports creating bucket names that contain uppercase letters or underscores.

• Upload a local file to bucket:

cd .aws
nano file.text
aws --profile default s3 cp file.txt s3://bucket/file.txt

• Download an object from bucket :

aws --profile default s3 cp s3://bucket/file.txt file.txt

• Delete the object from bucket :

aws --profile default s3 rm s3://bucket/file.txt

• Delete bucket :

aws --profile default s3 rb s3://bucket

Now, in order to mount the created OVH bucket as a file system, follow the steps described in my previous article : s3fs-fuse project.

For the url , make sure to use https://s3.gra.cloud.ovh.net that we’ve configured previously for the aws client. (as described before, replace grawith your corresponding region).
