I've build and maintain a bunch of multi-arch images myself for some of my smaller projects.
You can definitely build on an x86 system by using emulation. I used to install qemu and then use build args to ensure that the right base image was being pulled (eg
library/ubuntu
for x86 vsarmv7/ubuntu
for armv7) because otherwise, by default, an x86 machine would pull the x86 image. After building and pushing I generate a manifest and push that so that each platform pulls the right image. This is probably the simplest example I have of that since it's a single Python file.All that said... there is now an experimental feature of Docker available via the
docker buildx
command.Here's a recent (April) blog post from Docker about the new method. It's far simpler, so if you can get that working, it'd be ideal. I haven't taken the time to switch over myself just yet.

@girish I've already started and had some minor issues when using ubuntu 18.04, but running now on ubuntu 20.04 (step by step, following the install script so I can debug), and it seems to be going fine.
As for apps, I'll follow @yusf's link and @iamthefij's advice to package one of my own custom apps, which is VERY simple, and see how it goes!
-
Yeah, it seems
mysql-server-5.7
is not available (though there's a later version that is), and I wasn't able to get past installinglinux-generic
as well, since it seems kernel patching is not exactly the same under arm...Also, I saw the script downloads a specific version of nginx, which is amd64 as well. I'll keep trying, but I've been having network problems which I think have to do with the provider I chose. I'll get back when I have more news.
-
@malvim Yeah, you can adjust that apt line as needed. Essentially, you have to make the https://git.cloudron.io/cloudron/box/-/blob/master/baseimage/initializeBaseUbuntuImage.sh script succeed. You can make the script standalone, it does not require any args.
nginx ARM packages - http://nginx.org/packages/ubuntu/pool/nginx/n/nginx/
Node ARM packages - https://nodejs.org/dist/v10.18.1/
Docker ARM packages - https://download.docker.com/linux/ubuntu/dists/bionic/pool/stable/
Also, I saw you are testing in Focal. One issue I hit (even on x86) was that collectd has issues with the python3 plugin. I haven't gotten around to fix that.
-
@girish Yeah, I'll try bionic again, it just crashed on something related to
initramfs-tools
, and focal still does when i try to installlinux-generic
, which I assume has something to do with kernel images and the like? This stuff is a bit above my current knowledge, so I'm not exactly sure what I'm doing heheh. -
@girish great! I was already commenting out these lines to see where it went.
So it seems I'm losing name resolution after installing
unbound
. Installation ofresolvconf
is not a problem, but as soon as I install unbound, lots of names stop resolving and I can't install anything anymore.Not sure how unbound works, might have to go into it a bit more, but my guess is maybe the problem is inside my provider. I'll check with @will later to see if we can try it in his device, and see if the problem persists.
-
Just to keep you guys updated on what's going on: I commented out unbound just to go through (and probably have to come back to it later, but still).
I also switched to installing nginx from the repos instead of downloading a specific package with curl manually, as their version is
arm64
and it seems the rpi I'm on isarmhf
, which I know nothing about but some nginx-arm64 dependencies were not being met.I switched node to the
armv7l
package and it went ok.I switched docker packages to
armhf
, they intalled okay, but it seems I don't have the overlay kernel module loaded and have NO IDEA how to load it heheh. A few google searches still got me kinda stuck, I'll try again tomorrow. -
Alright, so I learned how to load kernel modules, and the problem now is that the
/
partition in this particular provider is over nfs, and overlay is not supported.So, as this is not a problem with cloudron on a rasberry pi, and is particular to this provider, I'm thinking of trying to change the docker driver tomorrow, just to see how far I can get to...

Hey, yall.
So my Raspberry Pi finally arrived, and I could start testing cloudron on it without the hassles I was having with the hosting company. So here are some thoughts and the current bump on the road I'm trying to overcome:
- I was able to install cloudron pretty easily with just a few changes to the
cloudron-setup
script itself, and toinitBaseImage.sh
andinstaller.sh
inside the cloudron package that is downloaded from the internet bycloudron-setup
- The changes in
cloudron-setup
were just not upgrading the kernel (not installinglinux-generic
, like I talked to @girish about earlier in this thread), and not downloading the cloudron package from the website, instead using my modified version so I coud change things and test. - The changes inside the package were pretty much just changing
amd64
/x64
strings toarm64
in all the downloaded packages - Another important change is the boot part, where cloudron changes grub files, and I had to switch things to the
/boot/firmware
files - I was able to keep
unbound
untouched, I guess it was a problem with the hosting company
So that was what I had to do, and here are the things I'm currently thinking about this:
- It would be good to have the current architecture in a variable, say
arch
, but there's a few questions to answer, like:- The rpi I was using in the hosting company was not
arm64
architecture, butarmhf
, I think. If there's different architectures for different models, we'd have to test it on others. I currently own an arm64 rpi 4 model B. - Some downloaded packages use
x64
instead ofamd64
in their names, and stuff likearmv7l
for armhf architecture, it seems. We'd have to map these package names to their architectures in a more explicit way, I think.
- The rpi I was using in the hosting company was not
- We'd have to extract the boot configuration (grub vs /boot/firmware confs) somewhere
I'm now facing ANOTHER problem, which is: it seems my ISP doesn't allow me to forward low ports like 80 and 443, so I can't really host cloudron from inside my home at the moment. I'm starting another thread asking for ideas with that, but I can't test cloudron apart from the installation process (which went smoothly all the way to the domain setup, but then I can't access it because of port forwarding restrictions).
So there it is, this is were I'm at currently regarding installing cloudron on an rpi, I'd greatly appreciate any input, thoughts, ideas, whatever you guys have.
Cheers!

@malvim arm64 is only available on the rPi 4 as far as I recall.
armhf is for the previous models as they are 32bit ARM chips.It would be cool if both were supported and autodetected, but you should be aware of the arch differences between the different models.
-
@robi Yeah, I don't know much about the different architectures, and at present I don't have access to any earlier armhf model, so I'll keep pushing with what I have for now. Maybe if we can suport the arm64 rPi 4 to start, some modifications (like explicitly handling architecture information, different boot locations and whatnot) will help us deliver cloudron to other models more easily.

Just keeping everything relating to the rpi setup in this thread:
So I finished setting up, went to https://<ip> like
cloudron-setup
says, and started domain setup. As per the other thread, I set up my IP to the interface I'm using (wlan0
). I'm using Amazon AWS as a domain provider, and set up the keys and such.So cloudron was able to create the DNS records (using a subdomain, like
pi.mydomain.com
, which should - and does - create an A recordmy.pi.mydomain.com
pointing to my192.168
internal IP).Afterwards, though, cloudron is never able to check for the records, as I cannot seem to resolve the
my.pi
domain from inside the pi.Other stuff that happens:
sudo
always sayssudo: unable to resolve host ubuntu
, even though it does change user to root no problem;ubuntu
is the default hostname on a bare ubuntu 18.04 install on the pi;- I can
dig
other domains that are already hosted on my zone, and get corret responses.dig
- ing for themy.pi
domain either times out with a "no server could be reached" message, or, when I do it RIGHT AFTER a successfuldig
to other domain, returns an "empty" response (with a line indicating 0 answers, like this:;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1
)
I'm a bit over my skill level on this, so if anyone could chime in, id'd be greatly appreciated. Either with an idea on what might be going on, or maybe something I could do/check/run to get mor info on what might be going on.
Thanks!
