فشلت خطوة ./launcher rebuild app الخاصة بي مع الخطأ التالي:
[root@osestaging1 discourse]# time ./launcher rebuild app
...

Error response from daemon: container is marked for removal and cannot be started

لقد قمت ببعض البحث على الإنترنت حول هذه المشكلة، ولم أجد إجابة قاطعة. كان الاقتراح الأكثر شيوعًا هو إعادة تشغيل الخادم. نعم، إذا كانت هذه هي “الحل”، فإن Discourse ليس جاهزًا للإنتاج.
في حالتي، وجدت أنه—لسبب ما—كان هناك حاوية Docker واحدة بحالة “Dead”. إزالة هذه الحاوية “Dead” متبوعة بتشغيل ./launcher start app نجح!
لاحظ أيضًا أنني وجدت أن إعادة تشغيل خدمة Docker وحتى إعادة تشغيل الخادم لم تحل هذه المشكلة. فقط ما يلي نجح:
أولاً، دعنا نحصل على قائمة بجميع حاويات Docker. هذه هي الخادم المؤقت الذي أستخدمه لإثبات مفهوم Discourse لمنظمتنا، ويبدو أنه تراكم عدد كبير من الحاويات المتعلقة بـ Discourse. واحدة منها تبرز بحالة = “Dead”
