Загрузка изображений Docker в реестр

Декабрь 16, 2018

Технический совет № 57 объяснил, как создавать свои собственные изображения Docker. В этом конкретном блоге было показано, как создавать собственные образы WildFly Docker для CentOS и Ubuntu. Теперь вы готовы поделиться своими изображениями с остальным миром. Вот где Docker Hub пригодится.

Docker Hub — это «распределительный компонент» Docker, или место для хранения и поиска изображений. Из документа « Начало работы с Docker Hub» …

Docker Hub — это централизованный ресурс для работы с Docker и его компонентами. Docker Hub помогает вам сотрудничать с коллегами и максимально использовать Docker.

Запуск и передача изображений в Docker Hub довольно просты.

  • Для загрузки изображений в Docker Hub требуется учетная запись. Это может быть создано как объяснено здесь . Или довольно легко с помощью команды docker login .
