Additional information
A lot of dependencies for compiling seem to be missing from termux.

Note that running any kind of container (even the simplest runc-based) require custom kernel with additional features (e.g. cgroups: blkio, freezer, devices, memory, cpuset, cpu, cpuacct). Docker require much more things (e.g. kernel support for overlayfs, veth, bridges, etc...).

Podman also (ref #10200) runs with user namespace feature is seems:

When run without root, Podman containers use user namespaces to set root in the container to the user running Podman
Source: https://github.com/containers/podman#rootless

But I have not tested building it myself, build instructions here: https://podman.io/getting-started/installation#building-from-scratch

Otherwise Podman seems a good alternative to docker, ref termux/termux-root-packages#60

[Nitrousoxide]

Docker (and Podman by extension) can probably be setup through a QEMU vm. This page describes the general process for Docker, though Podman should be similar.

I don't know if a script to automate this process is outside the scope of Termux's package repo though.

It seems that this is not a problem that can be solved by software packages alone.

Although termux without root permission missing kinds of kernel features,
podman-remote mode still quite useful.
Or even use podman-machine to launch container via vm.
