Docker elasticsearch FileSystemException - 不是目录

Question

我对 Docker 和 ElasticSearch 都很陌生。我正在遵循教程并使用此 docker compose 文件来安装 ElasticSearch：

运行 docker compose 时出现

我期待弹性搜索服务器能够顺利运行。

Answer 1

这显然是安装路径问题。

简单来说，容器和宿主机应该交换数据。这是通过以下方式完成的：

匿名卷：容器停止时销毁，不是永久的。

命名卷：可以命名但不能指定路径。您可以通过以下方式找到路径：

docker volume inspect volume-name

bind-mount： 与命名卷几乎相同，但您指定路径。

以及你在容器中交换数据的地方，例如：

es-data-es03:/usr/share/elasticsearch/data

这意味着，您的主机之间应该在该文件上进行数据交换：es-data-es03和容器本身：/usr/share/elasticsearch/data 这可以确保即使您的容器关闭，您也可以在 es-data-es03 处获得数据。

但是你的错误表明：

FileSystemException[/usr/share/elasticsearch/data/nodes/0：不是目录]

这意味着您需要一个文件夹而不是文件。我检查了你的坐骑，它们都是一样的。某处可能存在损坏的卷文件。我会删除所有容器和卷并从头开始。

docker ps -a                   // Show all active and inactive containers
docker rm container-name       // Remove container one by one
docker volume ls               // Show all volumes
docker volume prune            // Remove all unused volumes
docker volume rm volume-name   // Remove volume by name

如果容器启动，您可以使用以下命令进入容器：

docker exec -it container-name bash

并检查文件。但它应该正在运行。
