Настройка приватного Docker Registry: Хранение и управление образами

# Запустить контейнер registry
docker run -d \

# Проверить работу registry
curl http://localhost:5000/v2/
# Вывод: {}

# Тегировать образ
docker tag myapp:latest localhost:5000/myapp:latest

# Отправить в registry
docker push localhost:5000/myapp:latest

# Получить из registry
docker pull localhost:5000/myapp:latest

# Список образов в registry
curl http://localhost:5000/v2/_catalog
