Description

Correctly configures Udocker so that it works properly in Termux.

Update - Thanks to @IntinteDAO, udocker is now officially available in the Termux APT Repo. I've updated the configs to use it.

What's Udocker?

It's a user-space implementation of Docker.

This means that it can, without root or custom-kernel, run Docker images and containers.

And it does this without spinning up an entire qemu-VM, which makes it much, much faster than any other alternatives.

Instructions

In Termux -

pkg i git -y && git clone --depth 1 https://github.com/George-Seven/Termux-Udocker ~/Termux-Udocker; git -C ~/Termux-Udocker pull; bash ~/Termux-Udocker/install_udocker.sh

And done.

Help text

udocker --help

Keep it updated

cd ~/Termux-Udocker; git pull

Examples

Here are example scripts provided for some popular Docker images -

[!NOTE] Popular Docker repos provide 64-bit images, but not all of them provide the older 32-bit images.

Running uname -m, if it shows 64, then your phone is 64-bit. Which means it'll work for everything given below.

You can still check if the repo supports 32-bit by checking the tag link next to the name.

Add PORT=number before the script. Port must be from 1024~65535.

Run custom commands

To override the default startup commands, append your own commands after the script, like this -

~/Termux-Udocker/s-pdf.sh 'echo hello world; echo hi'
