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.
Tbh a laptop is a “mobile” device
It’s a server with integrated UPS and KVM console.
Except for that time I took out the battery because it was swollen and took the screen off to help with cooling. At least I still have my K and M
Oh nice! I’d love to run an ad blocker/dns/reverse proxy on something with a little more beef than the Pi zero I’ve got now.
Jellyfin and or Pi zero does not like streaming through the video.local address I’ve got setup, so i have to use IP address to get anything without stuttering.
pi zero for streaming is insane not gonna lie. What sort of resolution do you stream it at?
A decently newish phone would blow even a pi 5 out of the water I bet. Modern GPU drivers from snapdragon or mediatek plus core designs that arent 7 years old out of the factory would be a godsend for low-watt homelabbers
Dang, I just realized I didn’t explain the setup well enough:
An old laptop runs the Jellyfin server, but the Pi runs the reverse proxy. For some reason, trying to use the reverse proxied address causes problems, but connecting directly to the laptop via IP address and port runs fine.
I tried a Jellyfin server with a pi 2 or 3 and it couldn’t serve more than one client at a time. So i imagine a zero wouldn’t even be able to load the app, much less serve anything :/
My main reason for running my DNS/ad block/nginx through the zero, sometimes the laptop goes down, freezes, or fails to clear the transcodes folder, so having that stuff separate keeps at least part of the network running.
The VM eats through the battery, that’s the only hangup I have with this. Otherwise that’s a fantastic idea.
If I trusted the battery tech more, I would use an old phone. But I’ve had one of those white plastic Mac books hooked up to power so long, the battery swelled out of its enclosure :/
Maybe there’s a way to disconnect the battery, or an app that switches off charging, so it drains enough to keep that from happening
There are root apps that can limit battery charge level. If you have an older phone that’s rootable, I would look into that.
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.
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!
I dont think I so much want this for my phone as for my homemade AndroidTV boxes. Losing the Linux functionality after switching from Kodi/libreelec had been my biggest pain point.
Can’t wait to see my TV boxes show up in my Beszel dashboard!
Can you tell me more about these homemade android TV boxes? I built a really shitty front end to “turn” my Linux based mini PCs into a media streamer but it lacks things like Chromecast and reliability haha
I have two TV boxes, one is a Raspberry pi 4, the other is a pi 5. I installed KonstaKANG’s android port for the Pi’s. Depending on your familiarity with flashing the Pi’s this video from Explaining Computers offers a way to get Konsta installed through PINN. Once they’re up and running they act just like a cellphone. This remote works really well.
Install f-droid, and/or obtainium, and/or Aurora Store and you can install whatever apps you want on the box.
I don’t personally use Chromecast, so I can’t vouch for that working. Mine is more centered around consuming Jellyfin (jellyfin android tv app), youtube (newpipe), podverse, and Radiodroid
I really liked Kodi, but could never get it to correctly sync across devices so I finally went the android route. I’ve been pretty happy
Feel free to pick my brain if you have more questions
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
https://docs.docker.com/engine/install/debian/#install-using-the-repository
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 wish all the logs at my company were as beautiful as these terminal logs
Please no. I can’t grep that. (Nor ingest it to splunk for more powerful searching.)
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’m assuming your phone has to be rooted for this right? Or is docker running without root? I didn’t realize anything like this was possible. This is interesting.
Nipe! Not rooted. In a VM though
I’ve never tried it on Android, but running Docker in rootless mode is doable, and is encouraged for security reasons. https://docs.docker.com/engine/security/rootless/
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.
Get steam-headless running on there
How do we activate this feature? I have it enabled after going into the developer settings menu but nothing seems to happen, I see mentions of an app but idk what the app is. I am on grapheneOS though instead of normal android so there could be something with that here.
Oh nvm I figured it out, it just took a bit for me to realize there was a new terminal app on my phone
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?
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.
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.
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.
