network bind mount?

[gofaster]

I would like to have the /recording and /config directories on a network mount.
It looks like the s6-overlay init process attempts to chown these directories to root, which fails on the network mounts.
Instead. can the user be made responsible for ensuring appropriate permissions to these bind mounts before starting the container?

It was done for simplicity, but if it breaks this use case it's not worth it.

Will fix soon!

[gofaster]

That would be super!

Somewhat along the same lines but for further thought...it seems that the /segments directory acts as a FIFO buffer for each camera. To further reduce SD card wear, it would be great if it was on a tmpfs RAM disk. However it probably would not scale well, depending on number of cameras, stream properties and lookback. (In my case with 3 test streams, the directory size varies between 45-51 MB)
Most likely not a major consideration since I'm guessing that most Viseron instances are deployed on well-equipped hosts rather than SBC's with limited erase-cycle/slow storage.

[gofaster]

Replying to myself. Never mind. I bound /segments to a 100MB tmpfs mount on the host and it's all good!

[roflcoopter]

Yes there is a section in the docs on the tmpfs actually.

Thanks for pointing that out. I had not looked at the docs for ffmpeg as I started with gstreamer. That's much better since I won't have to config a tmpfs on the host for the container bind.

What is the error that you get when you use a network bind? Does Viseron still start?
Trying to see if i can keep the chown part for simplicity but make sure Viseron still starts even if it cant chown

[gofaster]

It does start, just dumps a bunch of errors. I just reconfigured and am testing now with /config and /recordings network mounts. It is recording clips. Will have to see what happens when other file/dir operations are run.
