Cloudron on a Raspberry pi?

[malvim]

Hey, all.

Happy to say this is now going on on my raspberry pi:

I have NO idea wheter stuff is really working hahaha.
I'll probably choose a simple app and build it for arm64, then try to install it from command line and run tests, maybe?

Not sure how to run tests against addons, or even apps. Is there some documentation around about this? @girish, could you point me somewhere? Thanks!

[girish]

@malvim Wow, that's some incredible progress! If the status indicator is green, it's pretty sure that the addon containers are responding to health checks!

For the test for the addons, there is a test/ inside the repo of each addon. You can just do npm install and npm test.

[girish]

To be clearer, like this (say with postgres addon). The tests will always test the latest cloudron/{addonname}test image.

$ docker build -t cloudron/postgresqladdontest .
$ cd test
$ npm install # only have to do this once
$ npm test

> postgresql-addon@1.0.0 test /home/girish/yellowtent/postgresql-addon
> mocha --bail ./test/test.js

@malvim Our e2e tests use this app - https://git.cloudron.io/cloudron/test-app . You can just build it like any other app and deploy it on Cloudron.

Hey, @girish!

So I was trying to run the tests on the raspberry pi, had some failures, but they're also failing on my regular amd64 laptop with ubuntu, so I'm not sure what's going on.

I tried specifically the postgresql addon like you mentioned, with no changes, the auth and add database tests pass, but I always get a timeout on the remove database test, every time. Mail and sftp addon also fail at different points, so I'm not trusting the failed tests on the rpi.

I thought about trying to run the tests on my production cloudron server, but not sure I should.

Have you ever been through this?

[Lonkle]

I think ARM is the future so I'll be following this thread, love what I'm reading so far. Good stuff.

@malvim But if your test is failing on x86 and ARM, it probably isn't a CPU related issue IMO.

[malvim]

@Lonk Yup, those are my thoughts as well. The thing is, it seems the devs are able to run the tests themselves, so it seems there are no obvious problems anywhere heheh.

[malvim]

Okay, so I ran the tests on my production cloudron and they all passed. It seems they don't run on a regular machine previously to installing cloudron? Is that true? And SHOULD they? Maybe I'm testing it wrong heheh.

But it would be nice if we could just run the tests outside of any cloudron installation, so I could test the images themselves, separately, on arm64 before going with another full install.

What do you guys say?

Your steps for testing it on local are different right? Since production is already running. What are your testing steps in each scenario?

I'd say that's possible. We could just use Docker itself? That's what I do locally.

Anyway, what Rasberry Pi are you developing this on? I'll go run out and get one to see if I run into similar issues. ️ Very interested in Cloudron on ARM in 2030!

Yeah, I'm doing what @girish outlined in his latest response in this thread: clone an addon repo, docker build the image tagging it with whatever name the test runner uses (cloudron/postgresqladdontest in this case), npm install and npm test.

It turns out I'm getting failures in all that I've tried so far, so I don't feel comfortable saying I "have successfully built the images" when I can't run the tests. But I can't run them on my laptop as well, so who knows? Haha!

I had never played with one till this year, they're fun! I got the latest model, the Raspberry Pi 4. Powerful little thing! It'd be great to have another pair of hands on this.

[girish]

@malvim We never run tests on the Cloudron itself, only on the laptop! Can you give the output of the npm test command? What is the error?

[Lonkle]

@malvim Well, consider yourself not alone in this endeavor! I'd love to help and am very interested in porting this to arm. Depends on the number of dependencies from the base image as well as Cloudron itself.

I'll post back here when I get my Raspberry Pi; I'm excited! ️

Hey, @girish!

This is the output, and it just hangs after that and never exits. This happens on my laptop and on another machine I used for testing purposes. On my Cloudron, these tests passed and only the last one failed, the backup/restore one iirc.

this seems to be more of a problem than the timeout later

It's really not. This happens because the test always tries to remove the currentl running postgresql container before running the tests, so the first time you run, the container is not running and you get this message. Still runs the tests and some of them work.

[robi]

@malvim ok thanks, otherwise it looks like it's missing

..which would partially explain the timeout..

Is there anything in docker logs -f postgresql ?

[Lonkle]

Is it getting the token last when it should be getting it first in auth? I've gotta re-read this whole thread cause I'm missing what this unit test even is supposed to prove. That one module could run in a Cloudron environment?

Nothing that I thought was strange... Here's the output:

So, could anyone here just try and run tests for addons on their machines, without any cloudron-related stuff, then just clone an addon and try to test it?

I've ran tests on my laptop, and on a server I have access to that doesn't run cloudron, and both of them time out in the same place.

DON'T RUN this tests on your production cloudron like I did, it will delete and recreate your postgresql (or whatever addon you're trying to use) and apps will go down heheh. I had to restore a couple of apps' backups, but it's all good now.
