What platforms support arm64, if any?

[paul-theorem]

I am running unifi-controller on a raspberry pi 3B+. It was running successfully in 32 bit mode for a couple weeks - but then i ran into the mongodb 32bit data size problem:

---

Expected Behavior

unifi-controller should start in docker-compose.

Current Behavior

pi@unifi-controller:~/unifi $ docker-compose up
Starting unifi-controller ... done
Attaching to unifi-controller
unifi-controller exited with code 159

Steps to Reproduce

On the rpi, running raspbian, update and enable arm64

sudo apt-get update
sudo apt-get upgrade

vi /boot/config.txt:
add:
arm_64bit=1

sudo reboot

validate running arm64:

pi@unifi-controller:~ $ uname -a
Linux unifi-controller 4.19.97-v8+ #1294 SMP PREEMPT Thu Jan 30 13:27:08 GMT 2020 aarch64 GNU/Linux

Now, docker pull the arm64 version:

docker pull linuxserver/unifi-controller:arm64v8-latest
docker-compose up

docker-compose.yaml:

Environment

**OS: raspbian

pi@unifi-controller:~/unifi $ lsb_release -a
No LSB modules are available.
Distributor ID:	Raspbian
Description:	Raspbian GNU/Linux 10 (buster)

How docker service was installed:
docker pull command above, as well as docker-compose.yaml

Command used to create docker container (run/create/compose/screenshot)

Have you tried using a clean setup, not reusing your existing config from the 32bit setup?
You don't have to specify the arch when pulling the container. Use linuxserver/unifi-controller and docker will pull the correct arch.

On second thoughts, I'm not sure if I understand your 32 to 64 bit upgrade. Are you saying you only enable it in the boot file and then only ran apt-get update and upgrade? You have to install a 64 bit os to get it to work. I'm not sure raspbian have a 64 bit release for the pi 3.

[paul-theorem]

I have not, but i can do pretty easy. Let me try that and get back to you. I'll start with a completely empty data directory. I only care about the config (trivial to backup), not the history data anyway.

[paul-theorem]

First - trying with a clean setup, it does seem to error in the same way:

pi@unifi-controller:~/unifi64 $ docker-compose up
Creating unifi-controller64 ... done
Attaching to unifi-controller64
unifi-controller64 exited with code 159
pi@unifi-controller:~/unifi64 $ ls -la data/
total 8
drwxr-xr-x 2 pi pi 4096 Apr 23 09:26 .
drwxr-xr-x 3 pi pi 4096 Apr 23 11:16 ..

[paul-theorem]

Regarding "a 64 bit os" - raspbian seems to be in a mixed mode - with a 64 bit kernel, and some 32, some 64 bit packages. Clearly the kernel is running in 64 bit mode

pi@unifi-controller:~/unifi64 $ uname -a
Linux unifi-controller 4.19.97-v8+ #1294 SMP PREEMPT Thu Jan 30 13:27:08 GMT 2020 aarch64 GNU/Linux

aarch64

That said - i'm totally open to another OS, and is sort of what i was asking in the title.

Can you suggest an OS that is 64 bit arm? Ie - i'm happy to try a complete OS upgrade (i have several rpis) - but i don't know what OS to choose. I'd like to choose an OS where you might know and/or have tested or developed the 64 bit arm docker images?

What OS do you suggest for me - Raspberry PI 3B+

[tobbenb]

I found out after my last comment that the is is still 32 bit but you can run 64 bit binaries in a special mode.

I'm not sure which distros is true aarch64, but I think Ubuntu is.

[aptalca]

yeah, I recommend the official ubuntu. That one has 64 bit versions

[paul-theorem]

I will build out a new controller with ubuntu, and give it a try. Thanks for the recommendation. I think many (maybe most) running arm are on RPI 3 or 4 - so you might throw an OS recommendation on the default documentation. But i appreciate the response. Feel free to close this - or leave it open and I can comment in the next 24 hours when i give it a try w/ ubuntu.

[paul-theorem]

I can confirm ubuntu 64 bit works on rpi3 using (essentially) the same dockerfile as above.

Thanks.
