1.Установка Docker Установим пакеты необходимые для работы apt с https-методом и CA-сертификатами

# apt-get install apt-transport-https ca-certificates

1	# apt-get install apt-transport-https ca-certificates

Импортирование GPG-ключа, которым подписаны пакеты

# apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D

Добавление репозитария Docker

# echo "deb https://apt.dockerproject.org/repo debian-jessie main" | tee -a /etc/apt/sources.list.d/docker.list

1	# echo "deb https://apt.dockerproject.org/repo debian-jessie main" \| tee -a /etc/apt/sources.list.d/docker.list

Обновление локального кеша пакетов

# apt-get update

1	# apt-get update

Проверка того, что установка Docker будет производиться с официального репозитария Docker, а не с Debian-репозитария

# apt-cache policy docker-engine | less

1	# apt-cache policy docker-engine \| less

Candidate: 1.12.1-0~jessie
