Quick backup contains irrelevant debug log entries despite correct run flags

[GingerAdonis]

Version

21.9.0

Environment

OS: Ubuntu 20.04.3 LTS (GNU/Linux 5.4.0-77-generic x86_64)
Docker version 20.10.7, build 20.10.7-0ubuntu1~20.04.1
docker-compose version 1.29.2, build 5becea4c

Steps to Reproduce

1. Setup Sentry with a few projects.
2. Run Quick backup as mentioned in the documentation.

The documentation warns about this behavior when omitting certain flags. But it still happens when I run the proper example command.

Expected Result

Proper JSON file without extra debug log entries.

Actual Result

JSON file which looks correct apart from a couple of debug log entries:

Updating certificates in /etc/ssl/certs...
0 added, 0 removed; done.
Running hooks in /etc/ca-certificates/update.d...
done.

Thanks for the report! I think a better way would be for us to use a volume mount and write directly to a file there.

Still seeing this on 22.12.0

This is a duplicate of https://github.com/getsentry/sentry/issues/36868, which has more discussion, so I am going to close in favor of that issue. Fortunately: I am going to be working on this next quarter.
