Docker swarm mode, портьер, трафик

0 голосов
/ 01 января 2019

Я пытаюсь настроить веб-сервер в режиме Docker Swarm.Любая помощь приветствуется.

Моя идея состоит в том, чтобы настроить одну машину, чтобы она работала автономно, но была готова к масштабированию для балансировки нагрузки и отказоустойчивости.Я ожидаю, что traefik работает на всех моих узлах, а не только на master, как я видел в некоторых примерах.

Текущие проблемы:

  • Похоже, шифрование не работает, ноя не вижу ошибки в логах
  • Я не могу связаться с tratainik броска портьеана

Другой вопрос, возможно ли использовать встроенный ключ / значение Docker Swarm вместо Consul

Файл моего развертывания ниже:

Я еще не сообщал об этом, но нашел причину, по которой Portainer не был доступен, в моем файле развертывания раздел «метки» вышел из раздела «развертывание», куда его вместо этого нужно было вставить.

Но проблема с «Let's Encrypt» сохраняется, когда я работаю с «Consul».

Я добавил эти строки в служебные команды «traefik_init»: 

  - --traefikLog
  - --traefikLog.filePath=/logs/traefik.log
  - --traefikLog.format=json
  - --accessLog
  - --accessLog.filePath=/logs/access.log
  - --accessLog.format=json

И этообъем в контейнере traefik: 

volumes:
  - /home/dockers/traefik:/logs

И мне удалось лучше проверить журнал, я вижу эти ошибки, но я не знаю, как решить:

  1. Документы Traefik говорят , чтобы включить ведение журнала acme для Let's Encrypt info: acmeLogging = true
  2. Посмотрите мой пример Swarm Portainer плюс Traefik плюс еще на http://dogvs.cat
  3. Использовать журнал Swarm плота, а не консул для traefik?Нет, это невозможно как конечный пользователь.
