How the install works
A Stratum install has two stages. Neither needs internet access.
| Stage | Runs on | Does |
|---|---|---|
| 1. Console installer | The live system on the USB stick | Partitions the OS disk (or mirrors two), installs the base OS, and sets the management NIC, hostname and root access. Copies the release onto the disk. |
| 2. Install service | The installed node, on its first boot | Takes the cloud’s configuration (storage, network, DNS, time, services, admin), validates it against the machine, installs the platform and waits for it to be ready. Then it switches itself off. |
Stage 1 is answered on the machine’s screen or serial console. Stage 2 is answered over the network, from another machine, in one of two ways:
| Method | Best for |
|---|---|
| Web installer | A first install: a guided form in the browser at https://<node>:9443/. |
CLI and node.yaml |
Repeatable installs: stratum-installer from a shell, with the configuration as a file. |
Both write the same /etc/stratum/node.yaml and run the same install, and the
draft lives on the node: answers saved in the browser show in the CLI, and the
other way round.
An unattended install takes both stages from files on a USB stick and needs no input except removing the install medium.
Before starting
Section titled “Before starting”- The machine meets the requirements and the firmware settings are done.
- A free floating IP range on the LAN is chosen (a
/24is typical). - A workstation on the management network has a browser, or the CLI.
