<p>Ein Update-Skript in Ihrem mailcow-dockerized Verzeichnis kĂŒmmert sich um Updates.</p>
<p>Aber benutzen Sie es mit Bedacht! Wenn Sie denken, dass Sie viele Änderungen am mailcow-Code vorgenommen haben, sollten Sie die manuelle Update-Anleitung unten verwenden.</p>
<p>FĂŒhren sie das Update-Skript aus:
<div class="highlight"><pre><span></span><code>./update.sh
</code></pre></div></p>
<p>Wenn es nötig ist, wird es Sie fragen, wie Sie fortfahren möchten.
Merge-Fehler werden gemeldet.
Einige kleinere Konflikte werden automatisch korrigiert (zugunsten des mailcow-dockerized repository code).</p>
<h3 id="optionen">Optionen<a class="headerlink" href="#optionen" title="Permanent link">&para;</a></h3>
<div class="highlight"><pre><span></span><code># Optionen können kombiniert werden
# - PrĂŒft auf Updates und zeigt Änderungen an
./update.sh --check
# - Starten Sie mailcow nicht, nachdem Sie ein Update durchgefĂŒhrt haben
./update.sh --skip-start
# - Überspringt den ICMP Check auf die öffentlichen DNS Resolver (Bitte nur nutzen, wenn keinerlei ICMP Verbindungen von und zur mailcow erlaubt sind)
./update.sh --skip-ping-check
# - Wechselt die Update Quellen der mailcow auf nightly (unstabile) Inhalte.
NUR ZUM TESTEN VERWENDEN!! KEIN PRODUKTIV BETRIEB!!!
./update.sh --nightly
# - Wechselt die Update Quellen der mailcow auf stable (stabile) Inhalte (standard).
./update.sh --stable
# - Erzwinge Update (unbeaufsichtigt, aber nicht unterstĂŒtzt, Benutzung auf eigenes Risiko)
./update.sh --force
# - Garbage Collector ausfĂŒhren, um alte Image-Tags zu bereinigen und beenden
./update.sh --gc
# - Update mit der Merge-Strategie-Option &quot;ours&quot; statt &quot;theirs&quot;
# Dies wird **Konflikte** beim ZusammenfĂŒhren zugunsten Ihrer lokalen Änderungen lösen und sollte vermieden werden. Lokale Änderungen werden immer beibehalten, es sei denn, wir haben auch die Datei XY geĂ€ndert.
./update.sh --ours

<p>Siehe <code>git log --pretty=oneline | grep -i "before update"</code>, Sie werden eine Ausgabe Àhnlich dieser haben:</p>

<p>FĂŒhren Sie <code>git diff 22cd00b5e28893ef9ddef3c2b5436453cc5223ab</code> aus, um zu sehen, was sich geĂ€ndert hat.</p>

<p>Sie können sich in den Update-Mechanismus einklinken, indem Sie Skripte namens <code>pre_commit_hook.sh</code> und <code>post_commit_hook.sh</code> zu Ihrem mailcows-Root-Verzeichnis hinzufĂŒgen. Siehe <a href="../../manual-guides/u_e-update-hooks/">hier</a> fĂŒr weitere Details.</p>

<li>Fehlerkorrekturen eines Hauptupdates werden bei uns als "Revisionen" wie a,b,c (Beispiele: <code>2022-05a</code>, <code>2022-05b</code> usw.) erscheinen.</li>

<p><strong>nightly (instabile Updates)</strong>: Diese Updates sind <strong>NICHT</strong> fĂŒr den Produktivbetrieb geeignet und dienen lediglich dem Testen.

<p>Seit dem 2022-08 Update gibt es die Möglichkeit die Update quellen zu Ă€ndern. Bisher diente der master Branch auf GitHub als einzige (offizieller) Update Quelle. Mit dem August 2022 Update gibt es aber nun noch den Nightly Branch welcher instabile und grĂ¶ĂŸere Änderungen zum testen und Feedback geben enthĂ€lt.</p>
<p>Dabei bekommt der Nightly Branch immer dann neue Updates, wenn irgendetwas am mailcow Projekt fertig gemacht wurde was in die neue Hauptversion reinkommt.</p>
<p>Neben den offensichtlichen neuerungen welche sowieso im nÀchsten Major Update enthalten sein werden enthÀlt er ebenfalls erstmal exklusive Features welche eine lÀngere Testzeit brauchen (bspw. das UI Update auf Bootstrap 5).</p>
<h3 id="wie-bekomme-ich-nightly-updates">Wie bekomme ich Nightly Updates?<a class="headerlink" href="#wie-bekomme-ich-nightly-updates" title="Permanent link">&para;</a></h3>
<p>Der Vorgang ist relativ simpel. Mit dem 2022-08 Update (ein Update auf die Version voraussgesetzt) ist es möglich die <code>update.sh</code> mit dem Parameter <code>--nightly</code> zu starten.</p>
<div class="admonition danger">
<p class="admonition-title">Achtung<p>Bitte machen Sie vorher ein Backup oder folgen Sie dem Abschnitt <a href="#best-practice-nightly-update">Best Practice Nightly Update</a> bevor Sie auf die Nightly Builds von mailcow wechseln. Wir sind fĂŒr keinerlei Datenverluste/korruptionen verantwortlich, also arbeiten Sie mit bedacht!</p>
</p>
</div>
<p>Das Skript wird nun den Branch wechseln mit <code>git checkout nightly</code> d.h. es wird auch wieder nach den IPv6 Einstellungen fragen. Das ist aber normal.</p>
<p>Sollte alles problemlos geklappt haben (wofĂŒr wir ja auch vorsichtshalber ein Backup vorher gemacht haben) sollte nun in der mailcow UI unten rechts die aktuelle Versionsnummer samt Datumsstempel abgebildet sein: <br>
