Docker 容器中的 Elasticsearch - 简单重启后为 "failed to write in data directory"

Question

几周前，我创建了一个 elk 堆栈(elasticsearch、logstash、kibana)来更好地处理日志文件的负载。

一切都很完美。今天我在 logstash 中调用了一些新模式，出于某种原因，我通过 docker-compose down && docker-compose up -d 重新启动。

现在 elasticsearch 不再启动了。

好的，它看起来像一个简单的权限，问题，但在 chown -R 1000.1000 elasticsearch/ 之后它也会崩溃(并设置其他所有权)。

设置:我为 docker-compose 项目设置了一个带有 LVM 的服务器。在 docker-compose.yml 中，我描述了这三个服务。

version: '3'

services:
  elasticsearch:
    image: my/elasticsearch/image:5.4.0
    volumes:
      - ./elasticsearch/data:/usr/share/elasticsearch/data
      - ./elasticsearch/config:/usr/share/elasticsearch/config
      - /etc/localtime:/etc/localtime:ro
    environment:
      ES_JAVA_OPTS: "-Xmx4g -Xms1g"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    networks:
      - nginx_net

  logstash:
    image: my/logstash/image:5.4.0
    command: ["logstash", "-f", "/etc/logstash.conf"]
    volumes:
      - ./logstash.conf:/etc/logstash.conf:ro
      - ./logstash.yml:/etc/logstash/logstash.yml:ro
      - ./GeoDb/GeoLite2-City.mmdb:/GeoLite2-City.mmdb:ro
      - ./patterns:/etc/logstash/patterns:ro
      - /etc/localtime:/etc/localtime:ro
    ports:
      - "5044:5044"
    environment:
      LS_JAVA_OPTS: "-Xmx1g -Xms512m"
    depends_on:
      - elasticsearch
    networks:
      - nginx_net

  kibana:
    image: my/kibana/image:5.4.0
    volumes:
      - ./kibana/config/:/usr/share/kibana/config
      - ./kibana/config/kibana.yml:/etc/kibana/kibana.yml
      - /etc/localtime:/etc/localtime:ro
    depends_on:
      - elasticsearch
    networks:
      - nginx_net

networks:
  nginx_net:
    external: true

如您所见，我没有直接使用官方图像，我也安装了(此刻)XPack，所有三个图像如下所示

FROM elasticsearch:5.4.0

RUN bin/elasticsearch-plugin install x-pack --batch 

我做的第二件不同的事情是我没有使用命名卷。那是因为我喜欢有一个包含整个项目的文件夹，也更适合我的 LVM 管理。

root@xyz:/srv/elk# ls -l
insgesamt 43488
-rw-r--r-- 1 root root     1514 Jul  1 09:34 docker-compose.yml

我读到过像 local-persist 这样的插件可以使用命名卷，但也可以指定 DIR 来保存文件。但我也读到，docker 建议不要在生产中使用插件。

如果有任何想法/链接，我会非常高兴。

OK 很简单:在 docker-compose 项目的主文件夹中运行(在我的例子中)rm elasticsearch/data/nodes/0/indices/a94kXbSER2CE97qdPhgVLA/_s‌ tate/.es_temp_file 帮助我启动 EL再次……
