SYZOJ NG Demo

Here is a simple dockerized SYZOJ NG. Everything is done with the simple and stupid way.

This is only for demo. Do NOT use it on production. I'll publish a dockerized production version when appropriate.

docker run --name=demo \
           # You can mount data directories to access outside
           # But you need a copy of mysql's initial data directory of this image
           # --rm \
           # -v /root/data/minio:/root/minio-data \
           # -v /root/data/mysql:/var/lib/mysql \
           # -v /root/data/redis:/var/lib/redis \
           -e ENV=production \
           # (Optional) by default "SYZOJ"
           -e SITE_NAME="<your site name here>" \

           -e APP_LOGO="https://your.logo.url/logo.png_or.svg" \
           # The frontend URL you'll access it
           # It should be the same in Nginx
           -e FRONTEND=https://demo.syzoj.org \
           # It should be accessable by user and proxy_pass-ed to http://container_ip:2003
           # with http "Host" header set to 127.0.0.1:2003.
           -e MINIO_ENDPOINT_USER=https://demo.syzoj.org/minio \
           # It should be accessable by judge clients and proxy_pass-ed to http://container_ip:2003
