Nginx සහ Nodejs සමඟ ඇති හොඳම හා සරල සැකසුම නම් ප්‍රොක්සි_ප්‍රොටොකෝල් සක්රීය කර ඇති HTTP සහ TCP පැටවුම් ශේෂයක් ලෙස Nginx භාවිතා කිරීමයි. මෙම සන්දර්භය තුළ, එන්ජීඑක්ස් වෙත එන ඉල්ලීම් නෝඩ්ජ් වෙත ප්‍රොක්සි කිරීමට හැකි වන අතර, එස්එස්එල් සම්බන්ධතා බැකෙන්ඩ් එන්ජින්එක්ස් සේවාදායකයට (ය) අවසන් කිරීමට මිස ප්‍රොක්සි සේවාදායකයටම නොවේ. (SSL-PassThrough)
මගේ මතය අනුව, සියලුම වෙබ් යෙදුම් ආරක්ෂිත පරිසරයන් භාවිතා කරන බැවින් (හෝ විය යුතුය) SSL නොවන උදාහරණ ලබා දීමෙන් පලක් නැත.

දැන් සෑම දෙයක්ම පරිපූර්ණව වැඩ කළ යුතු අතර බර සමබර විය යුතුය.
නැවත මම ගැන ලියූ අතර ඒ Docker දී TCP බර balancer ලෙස විකිපීඩියා පිහිටුවීමට කොහොමද . ඔබ ඩෝකර් භාවිතා කරන්නේ දැයි පරීක්ෂා කරන්න.
