Если я размещаю свой микросервис на хост-компьютере, он работает должным образом, но если я размещаю то же самое в контейнере, я получаю эти ошибки:

Есть идеи, почему??

В выводе здесь вы можете увидеть

 2020-09-27T08:35:15.119Z - error: [DiscoveryService]: _buildPeer[blockit] - Unable to connect to the discovered peer peer1.blockit.co:8051 due to Error: Failed to connect before the deadline on Endorser- name: peer1.blockit.co:8051, url:grpcs://localhost:8051, connected:false, connectAttempted:true
  

что он пытается подключиться к localhost: 8051. Поскольку localhost преобразуется в контейнер, в котором вы запускаете свое приложение, оно его не найдет. Вероятно, вы переходите на localhost, потому asLocalHost что для вашего приложения установлено значение true
Вам необходимо установить для этого параметра значение false и убедиться, что ваше приложение в контейнере, в котором оно находится, может разрешать ожидаемые имена хостов, которые вы определили
