See my reply to a sibling post. Nextcloud can do a great many things, are your dozen other containers really comparable? Would throwing in another “heavy” container like Gitlab not also result in the same outcome?
that endlessly duplicating services across containers causes no overhead: you probably already have a SQL server, a Redis server, a PHP daemon, a Web server, … but a docker image doesn’t know, and indeed, doesn’t care about redundancy and wasting storage and memory
that the sum of those individual components work as well and as efficiently as a single (highly-optimized) pooled instance: every service/database in its own container duplicates tight event loops, socket communications, JITs, caches, … instead of pooling it and optimizing globally for the whole server, wasting threads, causing CPU cache misses, missing optimization paths, and increasing CPU load in the process
that those images are configured according to your actual end-users needs, and not to some packager’s conception of a “typical user”: do you do mailing? A/V calling? collaborative document editing? … Your container probably includes (and runs) those things, and more, whether you want it or not
that those images are properly tuned for your hardware, by somehow betting on the packager to know in advance (and for every deployment) about your usable memory, storage layout, available cores/threads, baseline load and service prioritization
And this is even before assuming that docker abstractions are free (which they are not)
Most containers don’t package DB servers, Precisely so you don’t have to run 10 different database servers. You can have one Postgres container or whatever. And if it’s a shitty container that DOES package the db, you can always make your own container.

You can typically configure the software in a docker container just as much as you could if you installed it on your host OS… what are you on about? They’re not locked up little boxes. You can edit the config files, environment variables, whatever you want.

True, but how large do you estimate the intersection of “users using docker by default because it’s convenient” and “users using docker and having the knowledge and putting the effort to fine-tune each and every container, optimizing/rebuilding/recomposing images as needed”?
I’m not saying it’s not feasible, I’m saying that nextcloud’s packaging can be quite tricky due to the breadth of its scope, and by the time you’ve given yourself fair chances for success, you’ve already thrown away most of the convenience docker brings.
Nothing to do with efficiency, more because the containers are come with all dependencies at exactly the right version, tested together, in an environment configured by the container creator. It provides reproducibility. As long as you have the Docker daemon running fine on the host OS, you shouldn’t have any issues running the container. (You’ll still have to configure some things, of course)
Any guidance on this? I looked into Synthing at one time to backup Android phones and got overwhelmed very quickly. I’d love to use it in a similar fashion to NextCloud for syncing between various computers too.
It really wasn’t all that complicated for me. Install the client on two devices set a share up on one device go to the other device Hit add device put the share ID in. Go back to the first devices admin and say allow the share
Well, it works in a different way than NextCloud. You don’t have a server, instead you just make a share between your computers and they are all peers.
It takes some getting used to the idea, but it’s actually much simpler than NextCloud.
So if I wanted to sync photos from my phone to the computer, then delete the local copies on my phone to save space, that would not work? E: But keep the copies on the computer, of course
@squidspinachfootball@marcos Syncthing syncs. It does one way syncs, but if your workflow is complex and depends on one way syncs that's probably not what you want.
Sync things between operational systems, then replicate to nonoperational systems, and backup to off site segregated systems.
I was very intimidated as well, I’ll try to simplify it, but as always check the documentation ;)
This is the process I used to sync between my Windows PC and Android phone to sync retroarch saves (works well, would recommend, Pokemon is awesome) I’ve never done it on a Linux, though i assume it’s not too different
I downloaded the Synctrazor program so that it would run in the tray, again I’m not sure what the equivalent/if this would be necessary on Linux.
No shade to the writers, but the documentation isn’t super noob friendly, as I figured out. I’d recommend trying to cut out all the fluff, and boil it down to bare essentials. Download the program (whichever one seems right for your device, there’s an app for Android) and follow the process for syncing stuff (I believe I used a video guide, but it’s not actually as complicated as it seems)
If you need specific help I’d be happy to answer questions, though I only understand a certain amount myself XD
I’m absolutely at that point with Nextcloud. I kind of didn’t want to go the syncthing route, but I’ll probably give it a shot anyway since none of the NC alternatives seem any better.
I run it and mariaDB in docker and they run perfectly when left alone, but everything breaks horribly if I try to do an update. I recently figured out that you need to do updates for NC in steps, and docker (unRAID’s, specifically) defaults to jumping to the latest version. I think I figured out how to specify version now so fingers crossed I won’t destroy it the next time I do updates.
This is probably what I’m doing wrong. I’m using linuxserver’s docker which should be okay to auto update, but it just continuously degrades over time with updates until it becomes non-functional. Random login failures, logs failing to load, file thumbnails disappearing, the goddamn Collabora office docker that absolutely refuses to work for more than one week, etc.
I just nuke the NC docker and database and start from scratch every year or so.
You absolutely need to move from patch to patch and cannot just do a multiple version jump safely. You also need to validate the configs between versions, especially major release updates or you risk breaking. New features and optimizations happen and you also may need to change our update your reverse proxy configuration on update, or modify db table configuration (just puking this from memory as I’ve had to do it before). I don’t know that there’s automation for each one of those steps.
Because of that, I run nextcloud in a VM and install it from the binary package. I wrote a shell script that handles downloading, moving the files, updating permissions and copying the old config forward, symlinking and doing the upgrade. Then all I have to do is log in as administrator, check out the admin dashboard and make sure there aren’t new things I have to address in the status page. It’s a pain, but my nextcloud uses external db and redis and PHP caching so it’s not an easy out of the box setup. But it’s been solid for a long time once I adopted using this script.
