2.8.13 安定版での再構築（アップグレードではなく、もともと 2.8.13 で問題なく動作していました）が私の環境で失敗しています。
通常、再構築が失敗した場合は ./launcher start app を実行して以前のコンテナを復旧できます（ただし、これはもうかなり長い間必要としていませんでした）。これも機能していません。コマンドライン上では通常通り「動作」しているように見えますが、サイトはオフラインのままアクセスできません。
サーバー B では設定に変更を加えていません。変更前の設定のまま再構築を試みたほか、Docker Manager のみ、プラグインなしでの再構築も試みました。サーバー A では、すでに他のサーバーで 2.8.13 を使用して正常に動作している単純なプラグインを追加するだけ（これが再構築を始めた理由です）を試しましたが、このサーバーでもプラグインなし、Docker Manager のみの両方で試しても成功しませんでした。
アップグレード前の既存のプラグインは、web パネルによると docker-manager 以外はすべて最新でした。app.yml からかなりカスタマイズされた部分をほぼすべて削除して試しました。
使用しているテンプレートは以下の通りです。
templates:
- "templates/postgres.template.yml"
- "templates/redis.template.yml"
- "templates/web.template.yml"
- "templates/web.ratelimited.template.yml"
- "templates/cloudflare.template.yml"
結局、VM スナップショットを復元するしかありませんでした。試した 2 つの異なるサーバーで同じ問題が発生しました。
ログの関連部分を取得するために、復元された VM で再度試みました。以下にログを記載します。
