Open the machine → Reinstall tab.

Reinstalling rebuilds the machine from scratch with a fresh operating system or application. The machine keeps its IP addresses, its hostname and its plan — only the disk contents are replaced.

Choose what to install

The page has two tabs:

  • Operating Systems — the standard distributions, each with a version selector. Your current OS is flagged Current OS, and the suggested option is marked Recommended.
  • Applications — pre-configured stacks that arrive ready to use.

Run the reinstall

  1. 1
    Pick the OS or application
    Select it and, for an OS, choose the version.
  2. 2
    Set the credentials
    Fill in Server Credentials — the root password for the rebuilt machine.
  3. 3
    Confirm you understand
    Tick I understand this will delete all data.
  4. 4
    Reinstall
    Click Reinstall and confirm in the dialog. The machine rebuilds and comes back on the new system.

SSH keys

The keys listed on the SSH Keys tab are written to the machine as part of this reinstall. That's the one moment they're applied, so check the list is right before you start — it's the difference between logging straight back in and having to fall back to the console.

If the machine is protected

After the reinstall

Your access details change: the new root password is the one you just set, and any application shows its access URL and credentials on the machine's overview page. The event is recorded in Activity.
