Openstack over k8s
Материал из noname.com.ua
Комплексное задание на знание K8s/Helm/OpenStack на 8 рабочих часов (1 день)
* Install openstack(ceph as storage) on top of K8s(All-in-one-installation) using openstack-helm project * change Keystone token expiration time afterwards to 24 hours * deploy 3 VMs connected to each other using heat
TL; DR
- Мне понадобилось примерно 13 рабочих часов что бы закончить задние
Хорошее:
- Задание можно сделать за 8 часов (и даже быстрее)
Плохое
- Практически невозможно сделать на ноутбуке без Linux.
- Примерно половину времени потрачено на попытку "взлететь" напрямую на Mac OS и использовать в качестве кластера K8s уже имевшийся minikube
Это был явный фейл - как минимум чарты ceph не совместимы с миникубом никак (https://github.com/ceph/ceph-helm/issues/73), до остальных я не дошел.
Деплоить без скриптовой обвязки явно заняло бы больше чем 1 день (на самом деле если не срезать углы пользуясь скриптами то минимум неделя)
- Когда я понял что задеплоить на миникуб за отведеннгое время не успеваю то решил настроить ВМку с убунтой и дальше работать с ней
Второй явный фейл (но не мой =) ) - то что задание требует минимум 8 гигов свободной памяти,
а на самом деле даже на ВМке с 16-ю гигами и 8 ядрами все шевелилось очень медленно. (Человек с ноутом с 8 гигами не сделает это задание из-за недостатка памяти)
Как следствие - регулярные падения скриптов из-за таймаутов,
Отмечу так же что с не слишком быстрым интернетом я наступил на проблему, что Pull образов был медленным и скрипты не дожидались и падали по таймауту.
Хорошей идеей было бы скачать образы заранее, но об этом я подумал уже в середине процесса и тратить время на анализ какие образы нужны, не стал,
Решение
Создание ВМки с Убунтой
https://docs.openstack.org/openstack-helm/latest/install/developer/requirements-and-host-config.html
System Requirements¶ The recommended minimum system requirements for a full deployment are: 16GB of RAM 8 Cores 48GB HDD
На этом этапе изначально я совершил 2 ошибки
- Создал слишком маленькую (мало CPU Cores) машину
- Не проверил пересечения сетей
Warning By default the Calico CNI will use 192.168.0.0/16 and Kubernetes services will use 10.96.0.0/16 as the CIDR for services. Check that these CIDRs are not in use on the development node before proceeding, or adjust as required.
Кстати, похоже что тут ошибка в маске в документации - реально используется маска /12

Подготовка
Если следовать инструкции и не пробовать ничего менять то никаких проблем на 18-й убунте не возникло.
Установка OpenStack
Если следовать инструкции то никаких проблем не возникает, за исключением таймаутов.
Насколько я смог выяснить - все скрипты делают корректную зачистку и потому перезапуск достаточно безопасен.
К сожалению я не сохранил список скриптов которые приходилось перезапускать
Проверка OenStack
После окончания проверил самым простым способом - работает ли keystone:

Конфигурация KeyStone
В задании сказано:
change Keystone token expiration time afterwards to 24 hours
Первое - проверим что там на самом деле

Похоже что TTL=12h
Быстрое чтение документации ( https://docs.openstack.org/juno/config-reference/content/keystone-configuration-file.html ) привело меня к мысли что нужно менять секцию
[token] expiration = 3600
Тут было принято решение сделать "быстро и грязно" и в реальном мире так скорее всего не выйдет,
1. Посчитать новое значение (вместо 24 вбил по ошибке 34)

2. Проверить что у нас один экземпляр keystone
Было б забавно если их было б больше и все выдавали токены с разным TTL

Тут конечно нужно kubectl exec ... но я решил срезать угол
docker exec -u root -ti 41e785977105 bash
Проверяю что запущено

Соответствует ожиданиям .
Содержимое файла /etc/keystone.keystone.conf тоже - там как и предполагалось 12h
[token] expiration = 43200
Поменять файл прямо на месте не удалось - что б уже все сделать не по правилам, изменил его снаружи на хосте
root@openstack:~# find /var -name keystone.conf /var/lib/kubelet/pods/8ca3a9ed-279f-11e9-a72e-080027da2b2f/volumes/kubernetes.io~empty-dir/etckeystone/keystone.conf /var/lib/kubelet/pods/8ca3a9ed-279f-11e9-a72e-080027da2b2f/volumes/kubernetes.io~secret/keystone-etc/..2019_02_03_12_37_10.041243569/keystone.conf /var/lib/kubelet/pods/8ca3a9ed-279f-11e9-a72e-080027da2b2f/volumes/kubernetes.io~secret/keystone-etc/keystone.conf
и, возблагодарив разработчиков за то что keystone запущен под Apache (что позволило сделать релоад а не пересоздавать контейнер, а я не был уверен что знаю как это сделать правильно)
