вольюмы хранятся в кластере ceph,
хостнейм контейнеру присваивает имя сервера, с помощью строки: hostname: '{{.Node.Hostname}}'
запускаем деплой:
docker stack deploy -c monitor.yml monitor
далее находим где запущена база:
docker service ps monitor_influx
заходим на эту ноду и выполняем команду:
docker exec `docker ps | grep -i influx | awk '{print $1}'` influx -execute 'CREATE DATABASE cadvisor'
далее можем заходить по ссылке:
http://monitor.test.ru
вводим admin admin
настраиваем соединение с базой:
сохраняем,проверяем:
импортируем наш дашборд:
находим файл dashboard.json со следующим содержимым:

всё как мы видим, дашборд добавлен.
можем переходить в него и увидим наши графики, в этом дашборде мы можем по отдельности выбирать наши сервера и отдельные контейнеры.
ну и всё, мониторинг пашет!
