Browse Clever Cloud Cellar with S3 Explorer
Cellar is the S3-compatible object storage add-on of Clever Cloud. Every add-on uses the same endpoint and Cellar ignores the region, so the only values that change from one account to the next are the key ID and the secret, both shown in the add-on dashboard of the Clever Cloud console.

Every value below is fabricated — they are shaped like real Clever Cloud Cellar credentials so you can recognise yours, and they authenticate nothing.

Fabricated keys. The preset follows the Cellar documentation; it has not yet been tested against a live Cellar account.
Where each value comes from
Endpoint
Single endpoint: https://cellar-c2.services.clever-cloud.com (the CELLAR_ADDON_HOST of your add-on).
Credentials
In the Clever Cloud console (console.clever-cloud.com), open your Cellar add-on: its dashboard shows the key ID (CELLAR_ADDON_KEY_ID) and the secret (CELLAR_ADDON_KEY_SECRET).
Notes
Leave the region empty. Bucket names cannot contain underscores (_). A bucket whose name contains dots is reached in path-style automatically, as the TLS certificate does not cover it.
What usually goes wrong
Leave the region empty
Cellar does not use the region, and Clever Cloud's own examples use default, us-east-1 or us-west-1 interchangeably. Left empty, S3 Explorer signs with us-east-1 and creates buckets without a location constraint; typing a region would send one with every bucket creation.
Bucket names with dots
A custom domain is served from a bucket named exactly like it, such as cdn.example.com. The certificate covers *.cellar-c2.services.clever-cloud.com, one level only, so a dotted name cannot be reached as a virtual host. S3 Explorer switches to path-style for those buckets on its own; other tools may need the option set by hand.
No underscores, one namespace per region
Bucket names cannot contain an underscore, and they are unique across the whole Cellar region rather than per account: a name another customer already uses is refused.
