Does not timeout

Hi,

I have launched a diuid container, but it fails to start, and the dots are pilling up for a day now.

[ ok ] Starting OpenBSD Secure Shell server: sshd.
waiting for dockerd .................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

Should there be a timeout after which you consider the start of dockerd should be considered failed?

Best,

Request: enable CI (travis?)

Does not finish `entrypoint.sh`

It seems to sometimes be stuck on this line:
https://github.com/weber-software/diuid/blob/master/entrypoint.sh#L41

as the line under it "waiting for dockerd" never gets shown in the console.

This seems to happen when I rerun the docker container. For example:

# entrypoint.sh does not finish here:

Wrong group for docker.sock prevent users requests

Hi! Thank you for great solution! You rock!

I'm trying to allow users to use DinD but got an error:

# docker run -it --rm -e DIUID_DOCKERD_FLAGS="--group docker" weberlars/diuid bash
root# useradd -m -G docker penguin && chsh -s /bin/bash penguin && su - penguin
penguin$ docker ps # Got permission denied...
penguin$ stat /var/run/docker.sock
Access: (0600/srw-------)  Uid: (    0/    root)   Gid: (    0/    root)

As you can see --group flag was ignored and the permission is 0600 root:root. How can I fix it to 0660 root:docker?

Docker arguments are ignored when starting the diuid container

If I try to start the diuid container all args I pass are completely ignored, for example, if I execute this:

docker run -it weberlars/diuid sh

the container will just exit after waiting for dockerd .... and the bash is never executed

Doesn't work on recent envs (Ubuntu 19.04, Docker 19.03+)

$ docker run -it --rm --cap-add=SYS_PTRACE -e TMPDIR=/umlshm --tmpfs /umlshm:rw,nosuid,nodev,exec,size=8g weberlars/diuid@sha256:7cb6ae37616dc4466f37aeb73d064e46381db488935fa17c70fc761eb56f1a64 docker info
