web сервис на spring boot не подключается к elasticsearch через докер контейнеры

Рейтинг: 1Ответов: 1Опубликовано: 25.06.2023

Столкнулся с такой проблемой. У меня есть web сервис на spring boot, который общается с elasticsearch. Elasticsearch я запускаю в контейнере docker. Если я запускаю web сервис на локальной машине, то все работает отлично, но как только я пытаюсь запустить web сервис в контейнере возникают ошибки

Проверяли ли вы сам контейнер Эластика? Мне кажется, что Connection refused вы ловите именно из-за ошибки при запуске контейнера. Попробуйте добавить памяти - ES_JAVA_OPTS=-Xms1G -Xmx2G и при запуске посмотрите на состояние контейнера.

Также обратите внимание, что даже явно указанное условие

depends_on:
  - b-elastic

не означает ожидания состояния "готовности" контейнера. В документации прямо указано, что

There are several things to be aware of when using depends_on:

  • depends_on does not wait for db and redis to be “ready” before starting web - only until they have been started. If you need to wait for a service to be ready, see Controlling startup order for more on this problem and strategies for solving it.
  • The depends_on option is ignored when deploying a stack in swarm mode with a version 3 Compose file.

Поэтому если в вашем случае веб-приложение запускается до готовности Эластика обслуживать входящие запросы, то вам необходимо либо прописать явный перезапуск при ошибке (простое решение в лоб)

  web-server:
    restart: on-failure:5

либо использовать условие service_healthy. Это вы дописываете в описание Эластик-контейнера:

healthcheck:
  test: curl -u elastic:elastic -s -f elasticsearch:9200/_cat/health >/dev/null || exit 1
  interval: 30s
  timeout: 10s
  retries: 5

А раздел depends_on приложения изменяете так:

depends_on:
  b-elastic:
    condition: service_healthy
