Security considerations

This is a very early version and there are things that are not secure:

• Anyone can restart and stop a job by going to the main page on IBART as long as they have authenticated themselves using Google. Anyone with a Google account can login and trigger rebuilds, cancel jobs etc. People abusing this will be banned.
• It runs Flask debug mode by default (consider using nginx for example instead of the Flask web server).
• Whatever is in the job definition file will be executed and it will do this with the same permissions as the server itself. So if one type cmd: rm -rf $HOME in the job definition file, then all files in the servers’ $HOME folder will be deleted. So be very careful with what you or someone else puts into job definition file.
