  <h1>Nextcloud Office</h1>
  <p>
    <span class="tag green">COMPLETE</span>
    Deployed <code>office.rmf44.xyz</code> as a Nextcloud All-in-One stack
    with Collabora + Whiteboard on <code>homework03</code>, with public
    ingress through <code>hawker</code>'s Caddy over a NetBird mesh.
    Replaces the retired OnlyOffice container.
    <strong>Cutover completed 2026-08-10.</strong>

  <h2>The goal</h2>
  <p>
    Replace the standalone OnlyOffice container on <code>hawker</code>
    with a full Nextcloud All-in-One deployment providing file sync,
    Collabora-based office editing (Word/Excel/PowerPoint), and the
    built-in Whiteboard. Public URL <code>https://office.rmf44.xyz</code>
    serves a single domain (no subdomain split). User data lives on
    <code>desslok</code> via NFS so existing backup snapshots still apply.

  <h2>Architecture at a glance</h2>

  <p><a href="architecture.html">Full architecture detail →</a></p>

  <h2>Why this approach</h2>
  <ul>
    <li>
      <strong>Single domain, no subdomain gymnastics.</strong> AIO's
      mastercontainer terminates TLS for the domain validation
      endpoint, but it does NOT proxy Nextcloud traffic — Apache does,
      on a non-standard port (11000). One Caddy block on hawker
      forwards to that port. No <code>office</code> vs <code>nextcloud</code>
      split needed.
    </li>
    <li>
      <strong>Data on desslok via NFS.</strong> Existing backup snapshots
      cover <code>/slab/container_storage/office</code>; AIO runs
      stateless otherwise. The bind-mount pattern keeps everything
      portable — destroy the AIO stack and the data is still there.
    </li>
    <li>
      <strong>Mastercontainer owns host :80.</strong> This is mandatory
      for AIO's domain-validation flow, but it conflicts with Apache.
      Moving Apache to :11000 lets both coexist on the same host.
    </li>
    <li>
      <strong>Own backup pipeline.</strong> AIO's built-in backup feature
      is disabled (<code>AIO_DISABLE_BACKUP=true</code>) because the
      data is already on NFS — the natural backup target. A daily
      systemd timer on <code>hector</code> SSHes to homework03 and
      runs <code>pg_dumpall</code> + a config tar + a user-files tar,
      all writing back to desslok via NFS.
    </li>
    <li>
      <strong>No adminer sidecar.</strong> The AIO admin UI on :8080
      has full container management; an adminer would just be another
      admin surface to secure. Dropped.
    </li>
  </ul>

  <h2>What's still on the day-2 list</h2>
  <ul>
    <li><strong>E2E browser smoke test</strong> — login flow + Collabora document open + whiteboard create verified via API; full UI click-through needs your eyes (the admin password is in the chat).</li>
    <li><strong>Additional users</strong> — currently only <code>admin</code>, <code>race</code> (Lord Race), <code>bettyanne</code> in DB. Family members can be added through the user management UI.</li>
    <li><strong>Talk container</strong> — disabled to save RAM. If video conferencing is needed later, re-enable via AIO admin UI.</li>
    <li><strong>Imaginary (image previews)</strong> — disabled to save RAM. Re-enable if Nextcloud previews become a complaint.</li>
  </ul>
