cd fluentd/

далее собираем наш образ:
docker build -t fluent .
если у нас есть прокси сервер то выполняем команду:
docker build -t fluent --build-arg http_proxy=http://адрес_прокси:3128 .

создаём архив, копируем его на остальные ноды и загружаем:
docker save -o fluent.tar fluent
scp fluent.tar node2:~/
scp fluent.tar node3:~/
ssh -t node2 "docker load -i fluent.tar"
ssh -t node3 "docker load -i fluent.tar"

тоже самое проделываем с образом куратора:
cd curator/
docker build -t curator --no-cache .
если есть прокси то используем команду в которой будет указан как http так и https:
docker build -t curator --no-cache --build-arg http_proxy=http://адрес_прокси:3128 --build-arg https_proxy=http://адрес_прокси:3128 .

создаём архив, копируем его на остальные ноды и загружаем:
docker save -o curator.tar curator
scp curator.tar node2:~/
scp curator.tar node3:~/
ssh -t node2 "docker load -i curator.tar"
ssh -t node3 "docker load -i curator.tar"

далее создаём основной конфиг для деплоя:
cat docker-stack-proxy.yml

Рассмотрим подробнее что происходит в stack
environment:
ES_JAVA_OPTS: "-Xmx256m -Xms256m"
тут задаётся переменная, в которой мы указываем количество выделяемой оперативной памяти для приложения

configs:
- source: elastic_config
target: /usr/share/elasticsearch/config/elasticsearch.yml

тут мы указываем что конфиг из переменной elastic_config кладём в контейнер по пути: /usr/share/elasticsearch/config/elasticsearch.yml

configs:
elastic_config:
file: ./elasticsearch/config/elasticsearch.yml

тут мы указываем откуда переменной elastic_config взять файл с хостовой тачки

environment:
ELASTICSEARCH_HOST: elasticsearch
ELASTICSEARCH_PORT: 9200
SCHEDULE: "* * * * *"
COMMAND: "curator --config /etc/curator/config.yml /etc/curator/action_file.yml"

тут мы указываем переменные для сервиса curator и добавляем в cron задание на выполнение каждую минуту, с указанием команды.
