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 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.

If you "need" arm 64 docker and can give me a good reason why, I might consider adding this to my repo. I really see no point at the moment. You might have. That's why I am asking you.

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

Not true: https://en.wikipedia.org/wiki/Alpine_Linux

Alpine Linux is a Linux distribution designed to be small, simple, and secure. It uses musl, BusyBox, and OpenRC instead of the more commonly used glibc, GNU Core Utilities, and systemd.This makes Alpine one of few Linux distributions not to be based on the GNU Core Utilities.

I think the Alpine version that is refered in this post is a bit outdated. Try using 3.19 or 3.20

why install X86 VMs when phone‘s cup are now arm . Wouldn't installing an arm system run more efficiently?

Maybe beacuse the most latest docker images are for x86, trying to do with arm docker images is a crazy headache in many cases, you will need build from sources of arm images.

Use this one https://github.com/sylirre/vmConsole

@Saikatsaha1996 Thanks, this works, but In this the VM is not getting ip address like 192.168.x.x so that I can ssh. How to do that?
