 You can build the website using Docker such as below (without augmenting your host environment):
 
 ```
-docker run --rm --volume="$PWD:/srv/flink-web" --expose=4000 -p 4000:4000 -it ruby:2.5 bash -c 'cd /srv/flink-web && ./build.sh -p'
+make docker-run
+```
+
+And then rebuild the site before merging into the branch asf-site.
+
+```
+make docker-rebuild
 ```
