我尝试运行多节点Elasticsearch从我的本地机器的docker容器。下面是我的docker合成文件:
version: '2.2'
services:

container_name: es01

当我运行docker compose命令时,我收到以下错误:
es01 | {"type": "server", "timestamp": "2021-05-29T12:08:16,409Z", "level": "WARN", "component": "o.e.c.r.a.DiskThresholdMonitor", "cluster.name": "es-docker-cluster", "node.name": "es01", "message": "high disk watermark [90%] exceeded on [6UfoOc1-QaCrrRlhLngSkA][es02][/usr/share/elasticsearch/data/nodes/0] free: 17.3gb[7.3%], shards will be relocated away from this node; currently relocating away shards totalling [0] bytes; the node is expected to continue to exceed the high

下面是我的Docker资源截图:

}
但是,我的Kibana不起作用了

在评论部分,我已经提到了我的问题,只是为了将来的参考,我在这里解释它:
1.超过磁盘水位线上限[90%][...]碎片将从该节点中移出:每当您遇到系统中可用磁盘空间不足时,这个错误就会出现。所以,为了克服这个问题,我不得不清理一些数据以腾出更多磁盘空间,我当前的可用空间是40GB,运行正常。
1.修复磁盘空间后,我遇到了另一个问题,即“最大虚拟内存区域vm.max_map_count [65530]太低,请至少增加到[262144]"。
所以这里我们需要增加Docker的虚拟内存。首先在windows中,我们需要在执行增加虚拟内存命令之前去Docker终端。
如果您的Docker使用wsl子系统,则
1.敞开式电源 shell
1.运行:
wsl -d docker-desktop
,这将进入Docker终端。1.运行:
sysctl -w vm.max_map_count=262144
重新启动您的Docker,一切就绪。
注:增加虚拟内存的问题已在此处得到解答:https://stackoverflow.com/a/66547784/596495

当您没有将卷挂载到
/usr/share/elasticsearch/data
时,也会显示此错误消息。ElasticSearch尝试将数据添加到容器的默认文件系统,但失败了。OP已经挂载了一个卷,但是搜索引擎会把这篇文章放在顶部,所以我把它贴在这里。你可以通过使用docker命令的
-v
开关添加一个卷来解决这个问题,或者在docker-compose.yml
中添加一个卷:
