elasticsearch - 如何将FSCrawler REST与docker-compose连接

Question

我已经使用FSCrawler成功索引了pdf，但无法连接到FSCrawler的REST客户端以建立通往Elasticsearch的 channel 。这是我在docker-compose中的命令:

command: fscrawler fscrawler_rest

我可以使用FSCrawler作业名称的索引查询elasticsearch并检索结果。然后，当我将--rest标志添加到我的docker-compose命令中时，我成功启动了REST客户端(尽管带有我不理解的警告):

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，当我尝试使用带或不带斜杠的curl时:curl -XGET "127.0.0.1:8080/fscrawler/"我得到了curl: (7) Failed to connect to 127.0.0.1 port 8080: Connection refused新的docker-compose命令供引用:

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

我似乎调试不好，因为docker-compose在容器运行时不允许CLI命令，但是我不明白为什么我仍然可以使用http://localhost:9200/fscrawler_rest在elasticsearch中达到我的工作索引。
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？

Answer 1

将端口添加到fscrawler

ports:
  - 8080:8080

给出空响应，除非您更改settings.yaml剩余URL:

rest:
  url: “http://fscrawler:8080”

到达名为fscrawler的Docker容器。
