Elasticsearch 和 kibana docker 映像无法正常工作

Question

我按照这里接受的答案How to use the official docker elasticsearch container?

但是 kibana UI 没有出现在浏览器 localhost:5601 中，可能是什么问题？

 [root@localhost ~]# sysctl -w vm.max_map_count=262144
    vm.max_map_count = 262144

 [root@localhost ~]# cat /proc/sys/vm/max_map_count
 262144
 [root@localhost ~]#

错误日志：docker-compose up

通过命令 docker ps ，我们可以告诉您的服务（kibana&es）都正常工作。

真正的问题是你的 Kibana 服务找不到 Elasticsearch 服务，因为它无法解析地址http://elasticsearch:9200。

你能分享你的 docker-compose 文件吗？我认为这是因为您在 docker-compose 中的网络不正确。

1. 运行docker exec -it kibana bash
2. ping elasticsearch，检查是否正常。
3. 退出kibana容器，运行命令docker inspect kibanadocker inspect elasticsearch检查两者是否在同一个网络中。
4. 如果不是，请将网络更改为下面的代码。

为您的容器添加一个网络。

version: '3'

  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:6.6.1
    container_name: elasticsearch
    environment:
