Docker on Termux [in a VM]

Create a Linux VM and install Docker in it so you can (slowly) run x86 Docker containers on your Android device.

Recommended to use SSH or external keyboard to execute the following commands unless you want sore thumbs. See https://wiki.termux.com/wiki/Remote_Access#SSH

  • Install QEMU

     pkg install qemu-utils qemu-common qemu-system-x86_64-headless
    
  • Download Alpine Linux 3.12 (virt optimized) ISO

     mkdir alpine && cd $_
     wget http://dl-cdn.alpinelinux.org/alpine/v3.12/releases/x86_64/alpine-virt-3.12.3-x86_64.iso
    
  • Create disk (note it won't actually take 4GB of space, more like 500MB)

     qemu-img create -f qcow2 alpine.img 4G
    
  • Boot it up

    qemu-system-x86_64 -machine q35 -m 1024 -smp cpus=2 -cpu qemu64 \
      -drive if=pflash,format=raw,read-only,file=$PREFIX/share/qemu/edk2-x86_64-code.fd \
      -netdev user,id=n1,hostfwd=tcp::2222-:22 -device virtio-net,netdev=n1 \
      -cdrom alpine-virt-3.12.3-x86_64.iso \
      -nographic alpine.img
    
  • Login with user root (no password)

  • Setup network (press Enter to use defaults):

     localhost:~# setup-interfaces
     Available interfaces are: eth0.
     Enter '?' for help on bridges, bonding and vlans.
     Which one do you want to initialize? (or '?' or 'done') [eth0] 
     Ip address for eth0? (or 'dhcp', 'none', '?') [dhcp] 
     Do you want to do any manual network configuration? [no] 
     localhost:~# ifup eth0
    
  • Create an answerfile to speed up installation:

    localhost:~# wget https://gist.githubusercontent.com/oofnikj/e79aef095cd08756f7f26ed244355d62/raw/answerfile
    
  • Patch setup-disk to enable serial console output on boot

    localhost:~# sed -i -E 's/(local kernel_opts)=.*/\1="console=ttyS0"/' /sbin/setup-disk
    
  • Run setup to install to disk

    localhost:~# setup-alpine -f answerfile
    
  • Once installation is complete, power off the VM (command poweroff) and boot again without cdrom:

    qemu-system-x86_64 -machine q35 -m 1024 -smp cpus=2 -cpu qemu64 \
      -drive if=pflash,format=raw,read-only,file=$PREFIX/share/qemu/edk2-x86_64-code.fd \
      -netdev user,id=n1,hostfwd=tcp::2222-:22 -device virtio-net,netdev=n1 \
      -nographic alpine.img
    
  • Install docker and enable on boot:

    alpine:~# apk update && apk add docker
    alpine:~# service docker start
    alpine:~# rc-update add docker
    
  • Useful keys:

    • Ctrl+a x: quit emulation
    • Ctrl+a h: toggle QEMU console

i have no internet why?

localhost:# ifup eth0 udhcpc: started, v1.31.1 udhcpc: sending discover udhcpc: sending select for 10.0.2.15 udhcpc: lease of 10.0.2.15 obtained, lease time 86400 localhost:# wget https://gist.githubusercontent.com/oofnikj/e79aef095cd08756f7f 26ed244355d62/raw/answerfile wget: bad address 'gist.githubusercontent.com' edit: This network setting work for me: localhost: # echo -e "auto lo\niface lo inet loopback\nauto eth0\niface eth0 inet dhcp" > /etc/network/interfaces localhost: # /etc/init.d/networking restart localhost:~# echo nameserver 1.1.1.1 > /etc/resolv.conf nameserver 8.8.8.8 does not work for me

Thanks for solving my problem. For me other problem is need modify /etc/apk/repositories enable community source, delete # in '#http://dl-cdn.alpinelinux.org/alpine/v3.12/community', otherwise run 'apk add docker' with error 'required by: world[docker-compose]'.

I tried running a Flask server in it and listen to port 5000 and host 0.0.0.0 which supposed to be accessible to all devices that connected to the same router. But in this case i can't even access it through my browser. Feel free to reply, any help will be appreciated.

qemu-system-x86_64 -machine q35 -m 1024 -smp cpus=2 -cpu qemu64
-drive if=pflash,format=raw,read-only=on,file=$PREFIX/share/qemu/edk2-x86_64-code.fd
-netdev user,id=n1,hostfwd=tcp::2222-:22,hostfwd=tcp::9000-:9000,hostfwd=tcp::4567-:4567,hostfwd=tcp::5344-:5344 -device virtio-net,netdev=n1
-cdrom alpine-virt-3.12.3-x86_64.iso -nographic alpine.img

This is crazy!! Spinning up a vm in my mobile and running docker in it 🚀

I updated my installer: https://github.com/egandro/docker-qemu-arm

  • latest (stable) alpine 3.19
  • that means latest docker + docker compose
  • mitigation for (well known) alpine dns and ipv4/v6 issues

Please report issues here: https://github.com/egandro/docker-qemu-arm/issues

I am trying to install with the aarch64 qemu but keeps getting
/dev/sda is not a block device suitable for partitioning.

All the step went fine but getting error at the Disk & Install step, looks like it is not able to find the disk.
which I created using:
qemu-img create -f qcow2 alpine.img 20G

I am using below command to boot:
qemu-system-aarch64 -machine virt -m 2048 -smp cpus=2 -cpu max
-drive if=pflash,format=raw,read-only,file=$PREFIX/share/qemu/edk2-aarch64-code.fd
-netdev user,id=n1,hostfwd=tcp::2222-:22 -device virtio-net,netdev=n1
-cdrom alpine-virt-3.19.1-aarch64.iso
-nographic alpine.img

@raj-sharma-git I have a question.

Is there a special reason you want to run arm 64? It is still not accelerated - far slower then x86_64 ( I read about 2x or 4x slower - not sure about this). Do you "need" it?

I consider finding out how that works - I still don't understand the reason.

I thought that the performance would be better because it operates on the same architecture as the phone's processor. My assumption was that it would opt for virtualization instead of emulation, leading to superior performance.

Guys do you know about proot-distro and ubuntu distro? It's much lighter and faster than qemu and supports docker not sure about alpine

Edit: forget that, it has errors with cgroups and I didn't know how to fix it
