Я часами пытался понять, почему docker просто так не работает на моей машине. Я использую Ubuntu 18.01 Xfce. Установили docker с официального сайта и попытались запустить тестовый образ с помощью команды docker container run -it -p 8000:80 nginx
. Сначала все работало нормально, но только я пытаюсь в другой раз, когда localhost загружается бесконечно l oop. Работает только после перезапуска docker и только в первый раз. Я также попытался отредактировать файл docker.service
в:
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -H fd:// -H tcp://127.0.0.1:2375
, как указано в инструкции https://docs.docker.com/install/linux/linux-postinstall/
, снова без изменений.
Есть ли решение этой проблемы? Это и проблема ОС? Какая-то проблема конфликта? Если да, есть ли решение?
ОБНОВЛЕНИЕ:
Эта команда ip addr show docker0
показывает, когда работает контейнер:
5: docker0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default
link/ether 02:42:4e:4b:8e:af brd ff:ff:ff:ff:ff:ff
inet6 fe80::42:4eff:fe4b:8eaf/64 scope link
valid_lft forever preferred_lft forever
ОБНОВЛЕНИЕ 2:
После ввода комментария sudo docker run -t -i nginx /bin/bash
и чтения tail -f /var/log/syslog
у меня есть следующие строки:

Я только заметил эти строки:

Не уверен, поможет ли это моему делу.
ОБНОВЛЕНИЕ 3:
Обходное решение - постоянно писать команду sudo ip addr add 172.17.0.1/16 dev docker0
.
