I'm guessing this string can be whatever you want it to be.
But yeah, I agree in general, some of the docs can be pretty opaque. For example, I wanted to configure NextCloud w/ Collabora in Docker, and I kept getting errors when trying to do what a few sites recommended. I ended up figuring it out, but only through trial and error. I'm going to go through the same pain this weekend when I try out ownCloud Infinite Scale up and running to compare.
I had very similar experiences with OCIS. Got it all set up following the quick start guide, found extremely odd and unacceptable behaviour with storage space ballooning, start troubleshooting and find “oh you had to do this, this and this manually, it’s in the docs” It is in the docs, but never referenced by any other part of the docs. Because why would you mention the thing that the admin must manually set up in 100% of installs in your setup guide?
Anyway I’ve become that guy ranting on the internet that I don’t want to be. So just so you don’t suffer as much as I did; you have to create scheduled tasks via cron or your preference of scheduler to clean your uploads folder and data blobs. This also did not fix my specific issue and I ended up giving up on OCIS and sticking to Nextcloud.
I'm going to run both in parallel for a month or so before trying to get my SO to use it so I can better estimate the WAF. So far, NextCloud is good enough, but it's kinda slow (and I have Redis configured) despite being on pretty beefy hardware (Ryzen 1700 w/ 16GB RAM). I really hate PHP, so I'd prefer a project I can contribute to if needed. I worked w/ Go for almost 10 years, so OCIS would be a natural fit, but I'd still contribute patches for PHP if that really was the best tool for the job. But I'm not going to get involved unless the project already does what I need (my contributions would be for smaller bug fixes).
But yeah, the OCIS docs look kinda mediocre from the little I've read of them. But at least I don't need to mess w/ PHP config most likely and can hopefully just forward HTTP requests to it.
The move from php to go and the slowness of NC is what attracted me to the project. But I’m going to wait a bit longer until we’re flush with 3rd party setup guides cause I simply do not have the time to wade through their docs.
Yup, that's why I started w/ NextCloud. It was painful enough getting Collabora working with NC, so hopefully OCIS is easier now that I know my Collabora setup at least works.
