docker - Kibana 没有连接到 elasticsearch docker

Question

ELK stack + docker 的新手。

尝试在 docker 中本地设置 ELK。

使用的命令是

docker network create elasticnew --driver=bridge
docker run --network=elasticnew --name elasticsearchnode -p 9200:9200 -p 9300:9300 docker.elastic.co/elasticsearch/elasticsearch:6.6.1
docker run --network=elasticnew --name kibana -e ELASTICSEARCH_URL=http://elasticsearchnode:9200 -p 5601:5601 docker.elastic.co/kibana/kibana:6.6.1

ElasticSeach 已启动，http://localhost:9200/ 正在提供 json 响应。

但是 kibana url ( http://localhost:5601/ ) 说“Kibana 服务器还没有准备好”请求在浏览器中不断旋转。

在查询 docker 容器时，它说，

CONTAINER ID:76fe82529fa9       
IMAGE:docker.elastic.co/kibana/kibana:6.6.1                                                      
CREATED:16 minutes ago
STATUS:Up 15 minutes 
PORTS:0.0.0.0:5601->5601/tcp                                            
NAMES:kibana

Edit on findings:-

1.最初的命令

docker logs kibana 

立即给出空响应。稍后在发出此命令时，以指数方式回复(5 分钟后也没有看到日志。)

2.虽然浏览器中的 localhost:9200 也复制了上述行为。(好像是，kibana 让 Elasticsearch 变得很忙)

3.检查了 kibana 容器，它还说状态为“正在运行”。特此分享日志。

C:\Windows\system32>docker inspect kibana

后悔那些大日志。

PS:我使用的是 Win 10 企业版、6GB RAM，在运行 kibana 和 elastic search docker 容器后，RAM 使用率接近 70% 及以上。

有人可以在这里分享一些意见吗

1. 为什么kibana无法连接elasticsearch？
2. 为什么 kibana 运行失败后 elasticsearch 也没有响应？

Answer 1

在我的例子中，问题是由于我的容器的命名...注意 --name elasticsearch 在这里:

docker run -d --name elasticsearch --net elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:7.4.0

docker run -d --name kibana --net elasticsearch -p 5601:5601 kibana:7.4.0

我给容器起了另一个名字，kibana 提示它无法连接。将其更改为 elasticsearch 然后等待大约 1 分钟让 kibana 创建其索引和安装插件。

只需检查 kibanas 的日志，直到它显示 "Server running at http://0:5601"

docker logs kibana
