Здравствуйте. Подскажите пож-та. Развернул k8s. 1 master и 2 worker nodы. При применении деплоимента (kubectl -n ktswebinar apply -f ./) состояние pods постоянно ContainerCreating.

root@k8s-master1:/home/dott/ktswebinar# kubectl -n ktswebinar get  pods                                             
NAME                          READY   STATUS              RESTARTS   AGE
ktswebinar-6b7c46b449-pxxww   0/1     ContainerCreating   0          38m

На GitHub написали что надо создать файл /run/flannel/subnet.env и добавить в него запись FLANNEL_NETWORK=10.244.0.0/16 FLANNEL_SUBNET=10.244.0.1/24 FLANNEL_MTU=1450 FLANNEL_IPMASQ=true

Запись добавил. Безрезультатно.

Ответ на: комментарий от kostik87

Спасибо. Я настраивал как здесь https://www.dmosk.ru/instruktions.php?object=kubernetes-ubuntu Изначально у меня всё работало. Под создавался и работал без проблем. Потом я пересоздал под два раза. Такое ощущение что где-то что-то забилось.

Никаких файлов для фланнеля создавать не надо, он работает из коробки без всяких файлов, если устанавливал по официальной инструкции. Если не работает - разбирайся с ним. Если не получается - давай полный список команд, которыми ты устанавливал куб и фланнель.

Это неправильная инструкция.

Тут правильная: https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/

Для flannel тут: https://github.com/flannel-io/flannel

Что describe-то выдаёт?

У меня такое бывало когда волюмы очень долго перемонтировались при обновлении стейтфулсета, или когда квот на новый волюм не хватало. Но это готовый кубер в облаке.

  1. Docker для установки не нужен уже много лет.

  2. Неправильный репозиторий для пакетов, URL репозитория изменился.

  3. Какие-то непонятные манипуляции с /etc/hosts

  4. Какие-то непонятные манипуляции с iptables

  5. Неправильная команда для установки flannel, он давно переехал в другой репозиторий.

Если это всё и заработает, то по чистой случайности.

Запись добавил. Безрезультатно

Сделай для начала kubectl edit deploy -n ktswebinar ktswebinar и добавь в контейнер ktswebinar что-то типа

command:
  - tail
  - -f
  - /dev/null

Смысл в том, чтобы вместо entrypoint у тебя выполнялась команда, которая ничего не проверяет. Если других проблем с подом нет, он запустится. Дальше можно, например, сделать 

kubectl exec -n ktswebinar имя_пода -- ls /run/flannel
и посмотреть что там с файлом
