Can't use docker daemon after using start-docker.sh

[DavidJakszta]

Bug description

I get this error when starting docker in this image. I use Docker Desktop on WSL2.

root@a48aec4bfb16:/# docker ps

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?`

Reproducable steps:

docker run -it --entrypoint /bin/bash cruizba/ubuntu-dind:latest

in bash
start-docker.sh
docker ps

Is this a bug or am i missing something?

You need to run it using the --privileged flag (which is insecure) or install sysbox and use the --runtime=sysbox-runc

I've tried both of those options or none of them, and I always get

After starting the container I can still attempt to run docker run hello-world and they all work

docker run -it -v /var/run/docker.sock:/var/run/docker.sock cruizba/ubuntu-dind:jammy-27.3.0 /bin/bash
docker run -it -v /var/run/docker.sock:/var/run/docker.sock --privileged cruizba/ubuntu-dind:jammy-27.3.0 /bin/bash
docker run -it -v /var/run/docker.sock:/var/run/docker.sock --runtime=sysbox-runc cruizba/ubuntu-dind:jammy-27.3.0 /bin/bash

@Roedy13 Can you show me the entire command you are using when it fails and your Docker Desktop version?

[Roedy13]

I'm on Debian 12, so sysbox is not compatible. That's probably part of my problem, I would still expect the --privileged option to work.

$ docker --version
Docker version 20.10.24+dfsg1, build 297e128

These are the entire commands. I'll ignore the sysbox for now

docker run -it -v /var/run/docker.sock:/var/run/docker.sock cruizba/ubuntu-dind:jammy-27.3.0 /bin/bash
docker run -it -v /var/run/docker.sock:/var/run/docker.sock --privileged cruizba/ubuntu-dind:jammy-27.3.0 /bin/bash

This is by no means critical for me. I'm using this in a gitlab CI runner and it seems to run fine in the runner with an ubuntu host system.
