運行在 docker 容器上的訪問服務器

Question

我正在通過我的 docker 容器運行 StanfordCoreNLP 服務器。 現在我想通過我的 python 腳本訪問它。

Github 回購我正在嘗試運行： https://github.com/swisscom/ai-research-keyphrase-extraction

我運行的命令給出了以下 output：

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

現在我嘗試通過在 config.ini 文件中指定主機和端口來訪問它，但出現以下錯誤。

docker ps顯示PORTS的空白列

Answer 1

如日志中所示，您的服務正在偵聽容器內的端口 9000。 但是，從外部您需要更多信息才能訪問它。 您需要的兩條信息：

1. 容器地址IP
2. docker向外部輸出這個9000的外部端口（默認docker不輸出本地開放的端口）。

要獲取 IP 地址，您需要使用docker inspect ，例如通過

docker inspect keyphrase-extraction | grep IPAddress

這應該給你一行顯示 IP 地址，你可以從你的本地主機使用它來尋址 docker。

關於端口，需要顯式暴露。 快速查看 repo 中的Dockerfile並沒有顯示任何EXPOSE docker 命令，因此默認情況下端口 9000 似乎沒有公開。

您可以通過將-p9000:9000添加到您的命令（格式為-p HOST_PORT:CONTAINER_PORT ）來公開它，如下所示：

docker run -p9000:9000 -v /home/goorulabs/NarrativeArcse-extraction/sent2vec/torontobooks_unigrams.bin:/sent2vec/pretrained_model.bin -it keyphrase-extraction    

完成所有這些后，您可以測試您的端口是否已成功公開，例如使用：

telnet 172.17.0.1 9000

假設上面是第一步得到的IP。
