With the latest release of android it now supports some Linux functionality. I got docker installed simply by following Docker’s docs.
Any thoughts or uses for a mobile homelab? What would be useful to have mobile?

my friends complaining that my plex server because I left my phone on the bus and it ran out of charge
The lines between mobile device and server get blurred even more.
Lmao this is amazing. The future is now…
This is simultaneously cool and cursed af.
That’s cool! I’ve always had the idea of a small k3s cluster on old phones with postmarketOS. I guess it doesn’t work with older phones which don’t have the latest Android Version but given the homelab trend generally goes towards small, low power devices, this could continue the trend with super small and low power phones. Probably in 2 years when current gen phones rotate out of company leasing contracts?
Oh man that’d be super cool. An ARM cluster of androids would be awesome. Battery backups built in!
Make sure you utilize the 80% charge feature
With the latest release of android it now supports some Linux functionality.
Wait, it does? Gonna have to check that out.
Early alpha, but yea it’s full on Linux in Android. Quite slick
Dope, seems to not have landed yet in LineageOS but the Terminal app is already installed. Just missing the toggle in the developer options.
Is it an app I should be able to just find in my installed apps or do I need to enable it?
Because as of now (Pixel 7, Android 15) I can only find Termux.You have to be on the March update, then go to Developer options -> Linux environment, and enable it. Then ‘Terminal’ will appear in your apps drawer.

Debian is supposedly coming to android. That would be cool.
That’s Debian in the screenshot
Oh nice! I can’t see very well on phone.
Um, what does that even mean?
Edit: Looks like it runs a VM. So some overhead, but still cool.
The day Docker works on Android, I’m settled.
Docker does work on Android. That’s what OP is showing off.
Well, if they manage to get it working on Android I’ll be really impressed.
Maybe one day it’ll even work on Android!
Even better, maybe it will support Docker.
these are the times when I get jealous, as an iOS user
You’re free to join us
latest release of android
Does that mean 15?
Yea kinda. Android is switching to quarterly releases, so my phone now says “Android 15” but this was QPR2 specifically
Thanks. My phone is on 14 and won’t get another update, oh well.
The change maker feature would be to arrive home and plug your phone in a dock station and have a desktop to use as a pc
This has been supported on Samsung devices for years - it was first added to the Galaxy S8 (2017). It’s called Samsung DeX. You can plug a phone or tablet into a monitor, keyboard, and mouse, and it gives you a full screen experience.
They have docking stations, but you can also just use a USB C hub.
I’ve been talking about this for years! I got the idea from razer but I’m imagining the laptop chassis adds a nice screen, enormous battery, better IO, and then it just uses the touch screen as the track pad.
It could be so cool
I have a Steam Deck dock specifically for this. Except the mouse comes up on the phone screen instead of the monitor. Weird bug.
But then how would I look at my phone while using my Desktop.
I’ll need a dummy phone to doom scroll on.
Maybe your own adblocker, I thought about doing that myself, I use the public one from adguard on my phone (dns.aguard-dns.com) but having it on your own device would be pretty slick perhaps. But thinking about it more, Google wouldn’t just let you use an internal IP for the private DNS. I have tried it with my locally hosted adblocker and it rejects it.
Or you could set up a dashboard like Homepage or Dashy, or Flame or ? Ultimately, your imagination would do! :)
I do it. It has be DOT and you have to have a valid cert.
Unfortunately, from trying this myself, I don’t think you can forward port 53 to the Android host, so that won’t work (easily). It seems that privileged ports aren’t allowed to be forwarded.
I’ll have to give this a shot with pi-hole later tonight.
What is the current wisdom about having an android device always plugged in? Some people say that it will kill and pillow the battery, but does it really?
I don’t know. I think they are pretty good at managing battery, and have a new setting for maxing it out at 80% charge, but I don’t think I’d put it near anything expensive for years on end.
The trick of retrofitting any battery powered device into a wired one is to remove the battery. No matter what, Li-ion batteries cannot sustain permanent power. Expensive adapters and new Androids can regulate power well, as can automations, but the best worry-free option is battery removal.
Edit: I’ve just remembered Fairphone, they’re bossing the mobile repair ability front and have removable batteries like pre-2012. Could get one of those
In the past people used tasker to charge at a certain threshold. Check with homeassistant people to see what they do.
Impressive! Can you please link the instructions you followed?
Some time ago I was hosting the full ARR suite, bitwarden, AdGuard etc, but it was usually a mess with direct installs. With docker it might be worth revisiting it.
My only advice, buy a usb-ETH dongle, it will make a huge difference in stability

That’s it lol. To turn on the terminal, it’s a developer option for now, and is very alpha, just search for Linux in settings after turning on dev mode
I can see my 5 year old android mobile struggling being a suitable self hosting machine… (Because of the battery).
But not gonna lie, having it working as a more advanced travel router connect to Tailscale sounds like a neat idea (which I think it is already possible? The other day I saw the client app that supports subnet routers? I just haven’t tried it, and it has a disclaimer that it drains the battery… So I didn’t end up doing that at that moment when I was away).
While this is very exciting, I just tried it, and the network connectivity seems to be broken. No IPv6.
Hmm I was messing with its networking. External vpns break stuff on GrapheneOS. Its internal IP was 192.168.0.2, and my network is different.
Yes, Linux is running in a VM, and the network interface is a virtualized veth interface connected to a host bridge. The host android system has IP address 192.168.0.1, and this network interface is called avf_tap_fixed (as seen from termux).
Any other tips for the VM and/or GrapheneOS compatibility? Ie: did you use a different profile? I run Debian throughout my house as is, but plan on integrating the VM for better integration but was a little hesitant to be an early adopter due to the potential nuances. (lemme know if you have a blog/gist/etc covering it too)
I used the owner profile. Idk much about it tbh, I have yet to do more in depth testing as my phone doesn’t have displayport functionality so I am a little discouraged to be an early adopter too. I couldn’t get SSH setup so typing a lot on the small keyboard wasn’t ideal.
I’d check Google/GOS docs for more info for now. I’ll bet there’ll be a lot in the coming years as fast as usecases
I can’t get it to have network connection while my phone is on cellular data. On wifi it’s fine.
I just checked, and I have connectivity while on cellular. Maybe (just wild speculation) your mobile network is IPv6-only? Android (not Linux) should list 192.0.0.4 as an IP address in that case.
It’s probably that. While on cellular my IP isn’t 192.0.0.4 (but it is in 10. space), but there’s probably some v6 somewhere in the way.
