Private Beta - Scalingo Object Storage Addon


This addon will provision a bucket and credentials to access a S3-like Object Storage service hosted in our infrastructure. The solution is built on top of NetApp StorageGrid.

Use this addon to store medias uploaded by your users and persist them through deployments, restart and other Scalingo operations. If you were using the standard, ephemeral file system of the container, the file will only be visible from one of the two containers and will disappear when the application is deployed/restarted.


When you’re adding the addon from our dashboard or with our command line tool:

scalingo scalingo-object-storage 5g

The following environment variables will be set:


Your application, if deployed, will be restarted with the newly created addon.

Import/export Data

You may want to import or export data to or from your object storage bucket, in this case you will need some specific tools. There is an Amazon S3 compatible API to access the data so any tool working with S3 will work with our solution.

The case of ‘s3cmd’

Install the tool from the website

Create a .s3cfg file in your user directory with the following content:

access_key = "access key id"
secret_key = "secret access key"
bucket_location = generic
host_base =
host_bucket =
signature_v2 = True
use_https = True

Example of usage

# List all the files of your bucket
s3cmd ls s3://bucket-name

# Download a file from the bucket
s3cmd get s3://bucket-name/filename.png

# Upload a file to the bucket
s3cmd put ./document.pdf s3://bucket-name

# Access help to get list of commands
s3cmd --help

Make bucket public

By default, the bucket is private, it means that to access a file, you need a signed URL generated by the app owning the credentials. If you want your users to access directly their files:

Define the following JSON policy file as public.json

  "Statement": [
      "Effect": "Allow",
      "Principal": "*",
      "Action": [
      "Resource": [

Apply the configuration with the following command:

s3cmd setpolicy public.json s3://<bucketname>
