Elastic Beanstalk: заголовки Cache-Control не установлены для ресурсов Rails (автономная версия Passenger)

Файл, который вы должны переопределить, находится на /opt/elasticbeanstalk/support/conf/nginx_config.erb.

Для этого просто создайте файлы ebextensions, как показано ниже.

Для меня это было результатом использования звездочки 3 с пассажиром 4, поскольку они перешли на 64-байтовые дайджесты.

 location ~ "^/assets/.+-[0-9a-f]{32}\..+" {

следует изменить на

  location ~ "^/assets/.+-([0-9a-f]{32}|[0-9a-f]{64})\..+" {
