MicroClouds are small footprint clusters of compute nodes with distributed storage and networking, optimised for repeatable, reliable remote deployments. MicroClouds are aimed at edge computing, as well as for anyone in need of a small-scale private cloud.
MicroCloud snap drives three other snaps (LXD, MicroCeph and MicroOVN) enabling automated deployment of a highly available LXD cluster for compute with Ceph as a storage backend and OVN as network backend.
MicroCloud supports single-node deployments, but at least 3 nodes are recommended for high availability.
Once the simple bootstrapping is completed, users can launch, run and manage their workloads using system containers or VMs, and otherwise utilize regular LXD functionalities.
To get started, LXD, MicroCeph, MicroOVN and MicroCloud snaps are needed. Users can install them at once with the command:
snap install lxd microceph microcloud microovn
The bootstrapping process starts with running
microcloud init on the initiating member
and microcloud join on the joining members if you're using more than one system
Following the simple CLI prompts, a working MicroCloud will be ready within minutes.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
If you’re running Ubuntu 16.04 LTS (Xenial Xerus) or later, including Ubuntu 18.04 LTS (Bionic Beaver) and Ubuntu 20.04 LTS (Focal Fossa), you don’t need to do anything. Snap is already installed and ready to go.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install MicroCloud, simply use the following command:
sudo snap install microcloud
Browse and find snaps from the convenience of your desktop using the snap store snap.
