أنسبل - كيفية حذف إعادة إنشاء ملف؟

Ansible بلا شك أفضل أداة لأتمتة البنية التحتية التي تستخدمها أفضل 500 شركة في جميع أنحاء العالم.

على Crunchify ، نشرنا عددًا كبيرًا من البرامج التعليمية على Ansible. يرجى إلقاء نظرة على Ansible Archive للاطلاع على كافة البرامج التعليمية التفصيلية. فيما يلي أهم 3 دروس.

  1. كيفية نسخ ملف أو دليل أو برنامج نصي من مضيف محلي إلى مضيف بعيد؟
  2. كيف تفرخ Amazon EC2 VMs باستخدام Ansible؟
  3. كيفية تنفيذ الأوامر على المضيفات البعيدة واستعادة نتيجة الأمر (السجل)؟

في هذا البرنامج التعليمي ، سوف نتناول 3 نصائح مختلفة أستخدمها يوميًا.

وهذا كل شيء. سيؤدي دليل التشغيل أعلاه إلى حذف ملف موجود باسم crunchify.txt وسيقوم بإنشاء ملف جديد بمحتوى فارغ.

كالعادة ، أخبرنا بأي استعلام أو أي مشكلة تعمل فوق Ansible Playbook.
