Cloudron App: FluxBox Desktop With FlatPak

An app that gives you a full desktop in the browser.

How to Use

Other than pcmanfm, firefox, and xterm, most apps you will probably use will need to be installed via flatpak - this was done as flatpaks are isolated and easy to control where files install. Flatpaks allow me to keep the cloudron standard read-only file system and keep apps installed to the cloudron app in backups.

To install an app, you simply install it's flatpak: flatpak --user install <path_to_pakref_file> or flatpak --user install flathub <packageID>

Fluxbox is configured to open firefox normally or to flathub for easy download of flatpaks.

Fluxbox (and the user session) run under the username desktop which has it's password disabled and su/sudo is not possible. This helps with security but also I've had trouble running stuff as root via the noVNC stuff (for now).

VNC Also does not have a password on it - I don't think it's really needed (but can be applied if enough people ask) since this app is protected by the cloudron proxy (requires login to access the webapp)

Warnings

• I built the app, and although I am a trusted developer here, please note I DID NOT MAKE THE APP WITH SECURITY IN MIND.
• This app is considered alpha-stages. It may crash, it may burn, it may take your first born.
• Please PLEASE don't use this in production until it can be vetted by a few other people.

Installing

Once I get the package finalized I will push to cloudron's public git server for cloning

Also, if anyone know's how to get flatpak working properly in cloudron's docker apps it would be great!

[timconsidine]

@murgero very interesting!

[mehdi]

Doesn't flatpak use virtualization ? Using virtualization inside a virtualized env is always a pain ...

[murgero]

@mehdi as far as I know it does not. It works normally in docker - but the filesystem restrictions cloudron puts on it's containers is a bottleneck for it. I got it to install apps but they won't load otherwise.

This looks brilliant - and we've been recently investigating other solutions towards this exact need for templated and managed VDIs:

@murgero We'd like to give it a try, could you share the app?

[murgero]

@vladimir-d Give me a PM, and I can share the repo privately for now

[malvim]

Wow, that's pretty neat!

I had seen someone running desktop apps as docker containers with web frontends. Found this with handbrake, for example, and it works pretty well: https://github.com/jlesage/docker-handbrake

Not sure if it's the same approach or if it can help you in any way, just thought I'd mention. I love this idea!

[marcusquinn]

@murgero Can you have a think about this; making a lite' and a loaded version?

• Lite: I'm thinking only needs a Browser. Perhaps Waterfox.net is leaner for this too.
• Loaded: Would have all the extra/common Apps pre-installed: Waterfox, Thunderbird, Vivaldi, Libre Office, Rocket Chat, Bitwarden, PDF Arranger, maybe some others.

[murgero]

@marcusquinn Neat idea. However, Flatpak will allow users to install those apps as they need them. I think the only version I'll be making, for now, is a lite version. Right now it has a file manager, terminal, RDP Client (for thin client like purpose), and a text editor.

[marcusquinn]

@murgero My world generally involves explaining the same thing to about 100 people, who then all have to do the same reliably.

Hence, I tend towards just do it for them to save the explanations, and thereon inevitable questions that there's not always time to answer or document.

@vladimir-d and I will help work on this though, and everything we do is for sharing back.

Thanks for the innovation with this, it could become very useful!

[marcusquinn]

Thinking out loud on if we'd be able to get ZorinOS 16 Pro Lite (based on Xfce Desktop) running with this methodology?

• https://blog.zorin.com/2021/12/08/zorin-os-16-lite-is-here/

[murgero]

@marcusquinn It should be possible - but the idea here is to keep the UI as lite as possible, and Zorin, even the lite model, takes up a minimum of 2GB RAM. My current setup at the moment only needs 256 to 512

[marcusquinn]

@murgero Nice - but OS RAM usage nowadays is pale in comparison to that of websites and apps, and we'll be throwing big dedicated servers at this if we can get it all doing what we need, probably budgeting 4-16GB RAM per concurrent user.

Plus, I really like ZorinOS, highly recommended!

Also check out what Kasm is doing in this space - pretty slick!

[murgero]

@marcusquinn You're always welcome to customize to your needs - this was made for me to use as more of a lack-of-workspace situation so I can RDP into a windows machine or simply open my email in a better webclient than my mobile client.

[marcusquinn]

@murgero Thanks. Just gave it a spin, and it is super fast, no problem watching YouTube videos at full framerate!

[marcusquinn]

@doodlemania2 Looks amazing - links for reference:

@marcusquinn If only I could get sound working properly lol

Still working out a bunch of kinks like allowing users to change the resolution, sound, flatpak (for the advanced users) and so on
