Install Sovereign Stack installs everything you need to successfully execute Sovereign Stack on your management machine. You should go take a look at it, as it requires sudo.

Bare Metal Management Machine Requirements

The management machine itself should be Ubuntu Desktop 22.04 or later. It is recommended to use ZFS-based full disk encryption option along with a complex password. Of course, the bare metal machine must support the creation of VMs using LXD to host the SSME.

About the Sovereign Stack Management Environment creates the Sovereign Stack Management Environment (SSME). The SSME is a full VM that contains all the tools necessary for you to successfully control remote SSH and LXD cluster endpoints. This SSME gets created when you run the script on your bare-metal management machine.

Sovereign Stack installs the software necessary for you to run the SSME (run lxc list and seess-mgmt).  To create this VM, installs LXD which provides an API for spawning new VMs and the like. Sovereign Stack scripts do nearly everything within isolated VMs, minimizing the impact Sovereign Stack has on your bare metal machine.

Note! The SSME itself DOES NOT HOST Sovereign Stack workloads. The SSME is more like a central controller that builds virtual data centers on remote hosts. As such, in the SSME, ONLY the LXD client is used–not the daemon.

Volume Mounts

When the SSME is created, several directories on the bare metal management machine are mounted into the ss-mgmt VM including:

  • ~/sovereign-stack is mounted into the SSME at /home/ubuntu/sovereign-stack so the SSME has access to the Sovereign Stack Scripts.
  • ~/.ssh is mounted into the ss-mgmt vm at /home/ubuntu/.ssh. All remote VMs are pre-loaded with the ~/.ssh/ ssh pubkey so your SSME and bare metal management machine can SSH into VMs in remote Deployments.
  • Most important of all, ~/ss is mounted into the VM at /home/ubuntu/ss. This path stores all your remote.conf, project.conf, and site.conf files, as well as any generated artifacts and encrypted duplicity backups of the user data (i.e., websites) in your deployments.
  • If ~/.bitcoin exists, the SSME gains access to bitcoin/test block and chainstate data. This allows the SSME to upload that data to zfs storage volumes residing on remote cluster hosts. This means deployments can start block download from a pre-validated and known position, reducing the time it takes for each full node to reach the respective chain tip. (Note: this under development.)
Be sure to continaully backup your home directory so you don't lose all these important files!
