[Bug]: docker/containerd

[MassiWho]

Problem description

Hello, since the last update docker seems to have stopped working It looks like containerd is not able to bind its socket

What steps will reproduce the bug?

1. Start dockerd
2. Start any docker container:

sudo docker run -it --rm hello-world

What is the expected behavior?

The docker container should run without errors

I have the same question.

switched to docker inside alpine chroot

build runc with patch https://raw.githubusercontent.com/termux/termux-packages/master/root-packages/runc/cg-cpuset-noprefix-compat.patch

fix for docker: failed to register layer: Error processing tar file remount /, flags: 0x84000: invalid argument.

#replace rootfs with whatever you have
#before chroot
mount --bind rootfs rootfs
cd rootfs
mount ...
chroot ...

fix for iptables (if you have errors)

replace iptables binary with

#!/bin/sh
nsenter -t 1 -m iptables ${@}

may be unix socket path too long https://github.com/golang/go/issues/6895#issue-51285889

@Grimler91 Could it be that the issue described in https://github.com/termux/termux-packages/commit/8680546c85f3f86eb1888ecb4431032beb07af9c is not fixed with reverting to the older version?

[sylirre]

This issue can be fixed by moving docker directories either under /data/data/com.termux or even /data/docker. The idea behind is to reduce path as much as possible. Otherwise Unix socket path will exceed 108 characters limit and we'll see the error.

A possible temporary solution is to install a previous version of containerd

@sylirre, More precisely, the bundle.go.patch should change socketRoot to /data/docker/run/containerd rather than @TERMUX_PREFIX@/var/run/containerd in runtime/v1/linux/bundle.go. Also, in runtime/v2/linux/bundle.go the socket root should also be /data/docker/run/containerd rather than default.DefaultStateDir. (The latter requires the import of containerd/defaults to be removed or commented out.)

Any updates?

I also ran into this issue and this link seems dead :( Does anyone still have this package?
