elasticsearch - 如何将 FSCrawler REST 与 docker-compose 连接起来

问题描述

我已经使用 FSCrawler 成功地索引了一个 pdf，但我无法连接到 FSCrawler 的 REST 客户端来创建到 elasticsearch 的管道。这是我在 docker-compose 中的命令：

command: fscrawler fscrawler_rest

我可以使用我的 FSCrawler 作业名称的索引来查询 elasticsearch 并检索结果。然后，当我将--rest标志添加到我的 docker-compose 命令时，我成功启动了 REST 客户端（尽管有一个我不明白的警告）：

WARN  [o.g.j.i.i.Providers] A provider fr.pilato.elasticsearch.crawler.fs.rest.UploadApi registered in SERVER runtime does not implement any provider interfaces applicable in the SERVER runtime. 
      Due to constraint configuration problems the provider fr.pilato.elasticsearch.crawler.fs.rest.UploadApi will be ignored.
INFO  [f.p.e.c.f.r.RestServer] FS crawler Rest service started on [http://127.0.0.1:8080/fscrawler]

然后，当我尝试curl使用或不使用斜杠时：curl -XGET "127.0.0.1:8080/fscrawler/"我得到curl: (7) Failed to connect to 127.0.0.1 port 8080: Connection refused

新的 docker-compose 命令供参考：

command: fscrawler fscrawler_rest --loop 0 --rest debug

我似乎无法很好地调试它，因为 docker-compose 在容器运行时不允许 CLI 命令，但我不明白为什么我仍然可以使用http://localhost:9200/fscrawler_rest.

FSCrawler 正在使用 elasticsearch，但 REST 服务似乎无法正常工作。有没有人成功使用 FSCrawler REST API？

解决方案

将端口添加到 fscrawler

ports:
  - 8080:8080

除非您更改settings.yaml其余网址，否则会给出空响应：

rest:
  url: “http://fscrawler:8080”

到达名为fscrawler.
