People usually come here looking for advice on how to replace their dockerized nextcloud setup with a bare-metal setup. Now you came along presenting a solution to do the reverse! Bravo!
What do you guys think about putting the different components (webserver, php, redis, etc.) in separate containers like this, as compared to all in one?
I actually has a similar setup, but with nextcloud apache container instead of php-fpm, and in rke2 instead of docker compose.
Thanks for the kind words! Could you link me to the apache container you use? I would like to replace nginx since it's not officially supported but still need to do some research on apache
I'm currently using nextcloud:26-apache from here because some nextcloud apps I use is not compatible with v27 and v28 yet. The apache version is actually less hassle to use because nextcloud can generate .htaccess configuration dynamically by itself, unlike php-fpm version where you have to maintain your own nginx configuration. The php-fpm version is supposedly faster and scale better though, but chance that you won't see that benefits unless your server handles a large amount of traffics.
Docker is bare metal
Aye. Docker on linux doesn't involve any virtualization layer. What should the direct the installation setup be called? Custom setup?
Just non-container if you need to distinguish?
Well, since we want to be technical ... Docker is not bare metal. Linux apps are not bare metal. Arduino is bare metal.
No. The phrase means that you're not running in a virtual machine.
That's only the meaning you're used to, and that's my point. It depends on the context. I can assure you that, in the context of microcontrollers, for example, "bare metal" means running without an OS.
Either way its pretty stupid to use it in reference to containers.
My point is, since its meaning depends on the context, I don't see the issue for it to mean, in the context of containers, "outside of a container". Just like in the case of VMs, or OS vs No OS, it means there's one fewer layer between the app and the hardware, whether that's a VM, Container runtime, or the OS.
I'm pretty sure everybody, including you, understood its meaning in this context, it didn't really cause any misunderstanding.
No, it's confusing. Because some people do use VMs. So it makes it far less clear about what a person's setup is.
An application running in a container runs exactly the same as a non-container application. It uses the same kernel. And it all runs directly on the CPU. There is no metal/non-metal distinction to make. People just say it because it "sounds cool". And there are a lot of people in this community who don't understand what containers are. So it further muddies the water
If you weren't aware, Nextcloud provides non-AIO compose files in their docker repo: https://github.com/nextcloud/docker/blob/master/.examples/docker-compose/with-nginx-proxy/postgres/fpm/docker-compose.yml
Seems similar to what I'm doing but it uses the nextcloud:fpm-alpine image, which is community maintained. It's a valid approach but I prefer to tweak my php-fpm config myself. By using their docker image you basically lose a bunch of freedom to configure your setup, but it's easier to set up for sure
What do you guys think about putting the different components (webserver, php, redis, etc.) in separate containers like this, as compared to all in one?
It's much better to separate them. You can update them separately, you can configure and fine-tune them separately, you can reuse the images for different apps, you can reuse a container for multiple apps etc.
Not to mention not having to rebuild the all-in-one image yourself, which can get very finicky.
NextCloud’s trusted_proxies setting supports CIDR notation, so it mught be better to set the subnet of Traefik’s network as opposed to the IP address. That way, if you ever need to do anything with the container (I.e. upgrade traefik), the IP can change but the subnet is less likely to change.
True. That's a good improvement. Thanks a lot! By the way do you know if the nextcloud trusted_proxies setting allows for hostnames such as "traefik" as compared to just IP addresses?
The documentation seems to suggest just IP address and CIDR notation.
Alright, thanks a lot! You probably saved me a lot of headache in the future
No problem! It’s a small change that might not affect most people :)

Docker runs on bare metal
So does Hyper-V, what's your point?
The second sentence implies otherwise.
They're saying they've moved away from running things on bare metal and onto using them inside Docker instead.
