Overview

MicroCeph is Canonical's distribution of Ceph built for single node and edge deployments: it delivers the full Ceph storage engine, object, block and file storage on a self healing, strongly consistent cluster, as one snap that bootstraps a complete cluster on a single machine. You get a genuine Ceph object store you can point any S3 client, SDK or backup tool at, without assembling a multi node cluster or wiring up separate services.

This image turns a single VM into a working S3 compatible object store within minutes. At first boot it bootstraps its own cluster, provisions loop file backed storage so it runs standalone with no extra block devices, enables the RADOS Gateway as an S3 endpoint, and reaches Ceph HEALTH_OK out of the box. It suits development and test S3 targets, self hosted backups, and edge or lab object storage on infrastructure you control.

Why the cloudimg image

cloudimg ships MicroCeph as a secure, per instance appliance rather than a cluster to hand assemble. The cluster is never bootstrapped at build time: doing so would bake a shared ceph keyring and a fixed monitor address into every image, so instead each instance bootstraps its own cluster on first boot and mints its own credentials. Nothing is baked in, no shared cluster key and no fixed S3 keypair. Every instance generates a fresh S3 access key and secret key, creates its own gateway user, and generates its own TLS certificate, writing the details to a root only file on the machine. The S3 endpoint is served over HTTPS only, with no cleartext port, and SSH and the S3 endpoint are the only surfaces exposed. Every build proves storage genuinely works end to end, not merely that a port is open, by writing and reading back a real object through the gateway with the rotated keys. The base is fully patched with unattended security updates enabled, and every image comes with a step by step deploy guide tested against the exact build and 24/7 cloudimg support.

Common uses

A private, S3 compatible object storage endpoint for development, testing and CI
Self hosted backups and an on cloud S3 target you run and control
Standalone Ceph object storage for edge, lab and single node workloads
