MicroCloud creates a lightweight cluster of machines that operates as an open source private cloud. It combines LXD for virtualisation, MicroCeph for distributed storage, and MicroOVN for networking—all automatically configured by the MicroCloud snap for reproducible, reliable deployments.
With MicroCloud, you can eliminate the complexity of manual setup and quickly benefit from high availability, automatic security updates, and the advanced features of its components such as self-healing clusters and fine-grained access control. Cluster members can run full virtual machines or lightweight system containers with bare-metal performance.
MicroCloud is designed for small-scale private clouds and hybrid cloud extensions. Its efficiency and simplicity also make it an excellent choice for edge computing, test labs, and other resource-constrained use cases.
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.
Snap can be installed from the command line on openSUSE Leap 15.x and Tumbleweed.
You need first add the snappy repository from the terminal. Leap 15.5 users, for example, can do this with the following command:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Leap_15.5 snappy
Swap out openSUSE_Leap_15.5 for openSUSE_Leap_15.4 or openSUSE_Tumbleweed if you’re using a different version of openSUSE.
With the repository added, import its GPG key:
sudo zypper --gpg-auto-import-keys refresh
Finally, upgrade the package cache to include the new snappy repository:
sudo zypper dup --from snappy
Snap can now be installed with the following:
sudo zypper install snapd
You then need to either reboot, logout/login or source /etc/profile to have /snap/bin added to PATH.
Additionally, enable and start both the snapd and the snapd.apparmor services with the following commands:
sudo systemctl enable --now snapd
sudo systemctl enable --now snapd.apparmor
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.
