docker image的Elasticsearch服务未连接到webapp或kibana

docker image的Elasticsearch服务未连接到webapp或kibana,docker,elasticsearch,elixir,ecto,Docker,elasticsearch,Elixir,Ecto,我有一个docker-compose.yml文件，它声明了webapp、postgres数据库、一个两节点elasticsearch和一个kibana容器 version: '3' services: webapp: build: context: ../../../ dockerfile: config/docker/dev/Dockerfile-dev container_name: MyWebApp-dev image: 'localho

我有一个docker-compose.yml文件，它声明了webapp、postgres数据库、一个两节点elasticsearch和一个kibana容器

它们都成功构建，但kibana无法与elasticsearch建立实时连接

kibana           | {"type":"log","@timestamp":"2019-05-08T23:36:13Z","tags":["status","plugin:searchprofiler@7.0.1","error"],"pid":1,"state":"red","message":"Status changed from red to red - No Living connections","prevState":"red","prevMsg":"Unable to connect to Elasticsearch."}

kibana           | {"type":"log","@timestamp":"2019-05-09T00:02:46Z","tags":["warning","elasticsearch","admin"],"pid":1,"message":"No living connections"}

而且“产品”索引不能使用elixir/Exto mix创建

MyWebApp-dev |   (elixir) lib/calendar/datetime.ex:537: DateTime.to_unix/2
MyWebApp-dev |   (elasticsearch) lib/elasticsearch/indexing/index.ex:287: Elasticsearch.Index.build_name/1

MyWebApp-dev | 
MyWebApp-dev | ** (Mix) Index products could not be created.
MyWebApp-dev | 
MyWebApp-dev |     %HTTPoison.Error{id: nil, reason: :econnrefused}

一直以来，我都可以连接到elasticsearch服务器：

A68MD-PRO:~# curl http://localhost:9200/_cat/health
1557359160 23:46:00 docker-cluster green 2 2 2 1 0 0 0 0 - 100.0%

即使在容器内部，卷曲也会产生：

A68MD-PRO:~# docker exec elasticsearch curl http://elasticsearch:9200/_cat/health
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100    66  100    66    0     0   6969      0 --:--:-- --:--:-- --:--:--  7333
1557373042 03:37:22 docker-cluster green 2 2 2 1 0 0 0 0 - 100.0%

有人知道这个问题是关于什么以及如何解决它吗

更新：如果我这样做

docker exec -it MyWebApp-dev curl -XPUT 'http://elasticsch:9200/something/example/1' -d ' { "type": "example", "quantity": 2 }' -H'Content-Type: application/json'

它工作得非常好。因此，我认为这一定与httpoison有关。

elaticsearch容器与kibana容器位于不同的docker网络上

请验证此网络配置：

networks:
  - esnet

为弹性节点删除它，或为kibana应用完全相同的网络配置。

能否使用

network.host:0.0.0

network.host:0.0.0

？作为环境变量更新kibana设置？标准的是：server.name kibana server.host“0”elasticsearch.hosts xpack.monitoring.ui.container.elasticsearch.enabled true刚刚将server.host更改为“0.0.0.0”，但没有效果。坦率地说，无法创建索引的问题远比kibana的问题重要。我之所以提到它，是因为我认为它们是相关的。这是否也适用于webapp容器（同样，这是本文中更重要的问题）？在我看来不是。只要组件是可访问的，elasticstack不需要与应用程序位于同一网络上。在这种情况下，通过webapp的“links”配置，这是否也适用于webapp容器（同样，这是本文中更重要的问题）？在我看来，它不适用。只要组件是可访问的，elasticstack不需要与应用程序位于同一网络上。在这种情况下，通过webapp的“链接”配置
