peertube.conf overwritten on restart

[vividly8450]

In order to reliably stream 4K, I have to adjust three rate limiter settings settings in /etc/nginx/sites-enabled/peertube.conf. As shipped PeerTube limits the speed to 5 Mb/s, and recommends site admins review this setting in their post-install guide.

A 4K 60 FPS video with moderate compression can easily have a bitrate of around 50 - 75 Mb/s, so I typically set this value to around 150M to allow ample elbow room. But when I restart the service, all my changes are overwritten. The site becomes unusable because any 4K video begins to stutter badly.

I don't have this issue with my previous freestanding installation nor my YunoHost installation, so I assume Cloudron is pulling a default config file from somewhere. Is there any way to make my changes to this file persistent? On the host systems I do see multiple copies of peertube.conf and nginx.conf located at many different folders with paths like /var/lib/docker/overlay2/long_alphanumeric_string/, but as Docker isn't my forte, I'm not sure what I should and should not be modifying to do things "correctly".

Thanks!

UPDATE: I just noticed that the nginx.conf file is not writeable, even as root. But there has to be some way to modify the file. What's the correct way to do so?

@vividly8450 have you seen https://docs.cloudron.io/apps/peertube/ ?

It says there:

Customization

Use the File manager to edit custom configuration under /app/data/production.yaml

Does that work?

[vividly8450]

@jdaviescoates Unfortunately those are the PeerTube configuration options, which you'd normally set through the web interface. Rate limiting (specifically, the limit_rate and proxy_limit_rate directives) are set through the nginx configuration file at /etc/nginx/sites-enabled/peertube.conf, and there doesn't appear to be any way to access that through the file manager.

Interestingly enough I was previously able to modify this file to solve this issue (see here), but it appears something has changed since then.

any solution on that? how does your .conf look like somehow I can't find it.

@sponch we used the upstream nginx configs and indeed they have a rate limit by default. I am not sure why. I think the package can disable them.
