@nebulon wow, not my experience at all with the demo instance.. it seemed like the baserow instance was doing things I didn't want it doing, like downloading 1000+ stock images (that's not what baserow is for!).

Apparently, all those images are part of the "templates" - https://gitlab.com/bramw/baserow/-/tree/develop/backend/templates

echo "==> Syncing templates (in the background)"
/app/code/env/bin/python /app/code/backend/src/baserow/manage.py sync_templates &

And the above thing is also downloading a whole bunch of images from the web, not sure why.

PDFs as well as others, maybe something special about the file you try to upload?

Did something nefarious sneak in there? You can inspect the app at https://brow.demo.cloudron.io/ (cloudron/cloudron)

It'd be nice to be able to see what all is running and changing permissions. Is there a way you can run execsnoop from startup?

Here's more info on execsnoop and how to log all processes being executed (it may not work with our new kernels though).

You can apparently follow a process using strace. If you know the PID of the process then you can do:

strace -o strace-<pid>.out -f -p <pid>

Notice the -f switch. It will help you to follow newly created processes that are descendants of the process whose PID was used in the command, above.

https://github.com/a2o/snoopy also seems to record process execution, aside from doing full audit process accounting (psacct).

The start.sh has a chown -R cloudron:cloudron /app/data however as you indicated, something apparently changes ownership or creates files with root while the app is running.

Also all processes besides nginx are run as cloudron user https://git.cloudron.io/cloudron/baserow-app/-/blob/master/supervisor.conf

It will fail.

UPDATE:
The directories in /app/data/media are owned by root for some reason, chown -R to cloudron:cloudron does the trick.

Not sure why there is 62+MB of random images in user_files/, there's over a thousand files there!

Some images are back to root permissions after I did the chown to cloudron.

This is where I had this crash.

I uploaded csv files for import and that worked fine at least, so I guess there is some other area on the app where one can upload other things?
