Run as a docker container

Youtube Comment Crawler is also provided as a docker image, itslabq/youtube-comment-crawler. It stores database files in /data and you shouldn't give --dir option.

To run a container and mount ./data so that database files are stored in ./data:

$ docker run -d --name crawler -v $(pwd)/data:/data:Z itslabq/youtube-comment-crawler

If you want to crawl pages in another language, give the language via --lang option. The following example starts to crawl Japanese pages:

$ docker run -d --name crawler -v $(pwd)/data:/data:Z itslabq/youtube-comment-crawler --lang JP
