[image]How to completely uninstall / remove a plugin To remove a plugin, simply remove the - git clone https://github.com/... line from your app.yml file and rebuild your site via ./launcher rebuild app. I appreciate that, but rebuilding the app takes about 3 hours! And this is on a massive VPS. Wouldn’t it be a cool thing to be able to remove plugins just like we can add and remove themes? Perhaps something to consider as feature in future? Thanks!!

Server Total Memory: 4.657GiB, Kernel Version: 5.15.0-43-generic, Operating System: Ubuntu 22.04 LTS, 50GB SSD drive, 2.5 Cores, 5 Threads Intel® Xeon® CPUs … Not sure what could be wrong with that, other than it takes very long :confused:

3 hours sounds very wrong indeed. You need to investigate this issue and resolve that as first priority. There are ‘visual pauses’ in the build logging, this is normal, but that delay is not. My hunch is somehow you are starting to use swap during build, but I’m no SA. Are you running anything else on that machine? Downloads require unzipping, and that is computationally expensive, but its the same images for everyone. For reference I just rebuilt a site just now and it took 13 minutes, 46 seconds on a 2GB 2vCPU machine on https://scaleway.com

Nope, this is a VPS that is solely for this discourse instance. And I run many other VPS with the same company, which all run super smooth (but they are not discourse instances, they are other apps such as custom PHP or WP/CP CMS instances etc). I am not aware of any swap usage, and I cannot see any spikes in resource usages that would even justify Now it is at building.... - it seems a bit faster than last time, yet, it is still clearly over 20 minutes I will ask the server providers if they can spot anything unusual on their ends, however, I recall they personally told me that their own Discourse instance took about 2 hours as well to build. (PS These VPS are on Hetzner machines rented over a third party, I doubt I can get anything better.) In any case, my suggestion stands that it would be amazing to be able to add, and remove plugins like we can themes. Perhaps it is something to consider?

[image] Beda: that it would be amazing to be able to add, and remove plugins like we can themes I really don’t know anything, but AFAIK it is not possible, because Discourse is a lot of compiled javascripts. When there is need to add or remove something that changes how core is acting and working there must do rebuilding. Very much same situation than with Varnish for example.

Ok… Btw I checked in with server folks and indeed we hit 100% memory 5gb ??? 5gb ram is a bit a lot to consume for anything really. The discourse requirements say it need 1gb ram! And it is now stuck on below: 104:M 04 Oct 2022 07:19:27.251 # Redis is now ready to exit, bye bye... sha256:662695076506add39a630c2169b8b618f0121386951e93c6ffd2a6473107ae55 f4a95a1e69d5375e6ea30dfb22576209d249e5bc67b04a6fa09df289b1441888 Removing old container + /usr/bin/docker rm app app Thus I cannot even upgrade the server as the process would be interrupted. really, I do not think this is a server issue at all. If we need 1GB, then 5GB should be just more than enough. Something is wrong with this, massively wrong. I understand others must have a better experience (looking at @merefield who said to upgrade on a 2GB…) yet it is not working for us as it should. Anyway, it is off topic this thread I guess.

I just rebuilt another site, 4GB, 3vCPU, again < 15 mins (ie the extra memory/CPU didn’t actually help that much in my case, but still far from hours!).

The only I just notice is that my VPS uses vfs instead of the suggested aufs or overlay. Yet, according to this Can't run ./launcher rebuild app - Docker storage driver is unsupported - #45 by david, it shouldn’t be anything important, and thus we run the launcher with --skip-prereqs, because otherwise we cant even run Discourse. I do wonder if there is more to that storage driver requirement

[image] Beda: The discourse requirements say it need 1gb ram! That is a bit… over positive. For testing purposes it can be enough, and it can be a little bit tight even then. 2GB is much closer to reality. 4 GB is enough for bigger instances, though. But amount and power of cores plays important role too. And still… if you have 5 GB and rebuilding takes that long time there must be something wrong. I’m on DigitalOcean/4 GB/2 intel vcpu and rebuilding takes something around 25 minutes. What is your system exacly, plus app.yml — is there something custom?

Hi, the only custom really is what I mentioned before (vfs instead of aufs/overaly) The rest is vanilla.
