В версии 2.5.3 настройки системных свойств https.proxyHost, https.proxyPort и http.nonProxyHosts было достаточно, чтобы позволить серверу общаться снаружи. Например, он может извлекать метаданные изображений docker в Docker Hub.

Сейчас я тестирую 2.7.0, и этого уже недостаточно. Как правильно настроить HTTP-прокси?

В конфигурации ContainerRegistryAutoConfiguration используется HttpClients.custom(). Это причина?

Спасибо, что уловили это. Как вы знаете, у нас есть PR в разработке (spring-cloud / spring-cloud-dataflow # 4296), и когда это будет объединено, было бы здорово, если бы вы могли попробовать создать СНИМОК в своей среде, прежде чем мы отправим 2.7.1.

Не стесняйтесь также взвешивать изменения в PR. Любая обратная связь приветствуется!
