我正在通过Docker容器运行StanfordCoreNLP服务器。现在，我想通过我的python脚本访问它。
我要运行的Github存储库：https://github.com/swisscom/ai-research-keyphrase-extraction
我运行了以下命令：
docker run -v /home/goorulabs/NarrativeArcse-extraction/sent2vec/torontobooks_unigrams.bin:/sent2vec/pretrained_model.bin -it keyphrase-extraction
/app # cd /stanford-corenlp/
/stanford-corenlp # java -mx4g -cp "*" edu.stanford.nlp.pipeline.StanfordCoreNLPServer -preload tokenize,ssplit,pos -status_port 9000 -port 9000 -time
out 15000 &

现在，我尝试通过在config.ini文件中指定主机和端口来访问它，但是出现以下错误。

docker ps显示PORTS的空白列
答案 0 :(得分：1)
从日志中可以看到，您的服务正在侦听容器内的端口9000。 但是，从外部您需要更多信息才能访问它。您需要两条信息：
要获取IP地址，您需要使用docker inspect，例如通过
docker inspect keyphrase-extraction | grep IPAddress
这应该为您显示一行，显示可以从本地主机用于寻址docker的IP地址。
关于端口，它需要显式公开。快速查看仓库中的Dockerfile并没有显示任何EXPOSE码头工人命令，因此默认情况下似乎未暴露端口9000。
您可以通过在命令中添加-p9000:9000（格式为-p HOST_PORT:CONTAINER_PORT）来公开它，如下所示：
docker run -p9000:9000 -v /home/goorulabs/NarrativeArcse-extraction/sent2vec/torontobooks_unigrams.bin:/sent2vec/pretrained_model.bin -it keyphrase-extraction
完成所有这些操作后，可以使用以下方法测试端口是否已成功公开：
telnet 172.17.0.1 9000
假设以上是您从第一步获得的IP。
