Cloudron on a Raspberry pi?

[malvim]

Hey,

So I commented out the remove database tests because I had trouble connecting from the container, but the next test, use the database, starts like this:

// psql -h localhost -U usetestuser  -d usetestdatabase
describe('use the database', function () {
    const data = { database: 'usetestdatabase', username: 'usetestuser', password: 'somepassword', locale: 'C' };

    before(function (done) {
        async.series([
            addDatabase.bind(null, data),
            connectClient.bind(null, data)
        ], done);
    });

So I ran "psql -h localhost -U usetestuser -d usetestdatabase", using 'somepassword' as a password, and was able to connect, both from inside the container and from my host machine.

connectClient still doesn't connect, and, I get this on the screen:

    auth
      ✓ fails without access_token
      ✓ fails with invalid access_token
      ✓ succeeds
    use the database
usetestuser somepassword usetestdatabase 172.18.0.2 5432
      1) "before all" hook

  3 passing (2m)
  1 failing

  1) Postgresql Addon
       use the database
         "before all" hook:
     Error: Timeout of 100000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves. (/home/malvim/Projetos/Pi/docker/postgresql-addon/test/test.js)

      2) "after all" hook

Also, it does not seem to be network-related, since I get the same behavior on an ubuntu 20.04 VPS I have...

[malvim]

I tried recreating the steps inside the container using node, and could connect. I'm really at a loss here right now...

@malvim Wish I had my Pi now so I could help test! Soon tho. ️

[malvim]

Hey, @Lonk! You mind testing this on your laptop? I'm not getting these errors only on the Pi, I'm getting them on my amd64 laptop and amd64 server as well!

Repo is here: https://git.cloudron.io/cloudron/postgresql-addon, it's just a matter of:

• cloning it;
• building the image locally (docker build -t cloudron/postgresqladdontest .)
• installing dependencies (npm install)
• running the test (npm test)

Could you run this somewhere and see if you have the same problem?

Thanks!

[malvim]

MAN, it seems I'm running into ALL KINDS of weird problems hahaha!

I started going into postgresql node client's code, and it seemed to be some weird behavior of EventEmitter, which was weird...

I installed nvm and tested with older node distributions, and it ran fine on my laptop! So it seems, @girish, that the test code for postgresql-addon does not run with node v14 or later on my machines. Tested with v12 and v13 and it was all fine. What version are you using for tests?

Moving on to the next hurdle, I guess hahah!

Aha! I feel like I have hit this issue before. Indeed, when we updated the box code to use node 14 lots of things fail (not sure why). We use node 10.18.1 everywhere. This is why the hotfix and code enforces it. For future reference, always use the node in scripts/createReleaseTarball in the box repo.

[malvim]

@girish okay, cool, I'll use that. It's good news, then, that the OTHER tests even ran!

So, for what it's worth, the code seemed to fail on the use of EventEmitter. A class was dispatching an event and the corresponding listener was not triggered, so if you ever need to investigate further, maybe that's a start.

I have ordered a RaspberryPi 4 now as well and plan to use that as a home server, so hopefully we can get this supported well in the future Very curious to get my hands on what you have already managed to get working!

[robi]

There's the new keyboard that includes an rPi inside too.

[nebulon]

@malvim I've also got a Raspberry Pi 4 now. Can you give an update on where you are and do you have forked repos with arm changes somewhere?

[nebulon]

To give a short update from my side, with the information already posted here, I was able to get the box (the main Cloudron controller process) up and running on the Pi 4 as well as successfully install Cloudron as such. I have only just started on the base image and the other addons, so any patches here are welcome.

To collect the changes, I am creating arm64 branches in the relevant repos, for example https://git.cloudron.io/cloudron/box/-/commits/arm64 and https://git.cloudron.io/cloudron/docker-base-image/-/commits/arm64

On top of this, I am trying to implement a better provisioning workflow for development, this is similar to the hotfix, so it is still aimed towards developers porting stuff to arm. More info on this later.

@nebulon So quickly! Nice work.

I want to convert my app to run on ARM so I'll be getting the same board you got to verify the OpenVPN Client and all of its features are able to work in an ARM environment.

This is so cool, love ARM.

[nebulon]

Well it really remains to be seen how powerful such a board is to run common apps through docker

[Lonkle]

@nebulon True, but even if it could run 1. Not even that well, imagine a future with the Rasberry Pi 8. ARM CPUs are getting insane.

I'm running like 4 containers on my Raspberry pi at home, it's super smooth, and it's only a RPi 2 ! The RPi 4 is gonna be more than capable of running a few apps for home usage I think

[malvim]

@nebulon Great work!

I got really caught up with work and personal stuff over the last weeks, so I was not able to keep on working.

On most addon repos, I was creating arm64 branches as well, but most of them were just a matter of changing the base image to not have the hash. I was using cloudron/baseimage and building it on the pi itself before trying to install cloudron, so I had it tagged locally with that name, and others wouldn't download from docker hub, using the local arm64 one instead.

I'll search for any changes I have made over here, but they're not a lot.

I'll post a suymmary tonight.

[nebulon]

@malvim right, it was same route for me then. I have just managed to get all addons and nextcloud to run. The notes here about mongodb were helpful!

Overall I don't think it will be included in the next release though, maybe as something experimental, but while we have a proof-of-concept now, it will still take quite some time to actually make it proper and of course all apps have to be rebuilt...

[Lonkle]

@nebulon Let me know when you send are finished with your branch (and how we'd build it differently) and I'll make sure my OpenVPN Client is ready!

[girish]

@lonk Can you make a new post for the VPN Client with the current status? I would like to discuss a bit whether it should be part of the Cloudron box code or an app.
