ssh: Connection refused loop

[shivangp76]

Hello,

When running the "Quick Start Large Pre-Made Image" headless version, after a couple of minutes, I see the CLI, so it works, but when I use the non-headless version, the following message repeats on loop. I also get the same message when running headless, but after a couple of minutes the CLI loads. I have tried running the non-headless command for 3+ hours and still the message loops.

Disk is being copied between layers. Repeating until able to copy SSH key into OSX...
/usr/sbin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/arch/.ssh/id_docker_osx.pub"
ssh: connect to host 127.0.0.1 port 10022: Connection refused

Does this image work?

# Catalina
docker run -it \
    --device /dev/kvm \
    -p 50922:10022 \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e "DISPLAY=${DISPLAY:-:0.0}" \
    sickcodes/docker-osx:latest

Please post the error, it's most likely related to root/userspace display:

srwxrwxrwx 1 shivang wheel 0 Mar 10 08:47 X0
Shivang is running the X server, but I have a feeling you're running docker using sudo?

If not, are you running as root? If not, then run docker run without root, because root doesn't have a desktop open. If you can't run without root, add yourself to kvm and libvirt groups are you're currently missing from them

Also, apologies for making you wait 3 hours.

I should write a lil shell script that calculates how much % based off of df as I don't believe there's a way to verbosely show layer copy progress

Also, I'm not using sudo or running as root. I'm in the libvirt group, but I don't see a kvm group. Am I missing a package or something that would create the kvm group?

[sickcodes]

Should look something like this:

kvm:x:78:user,root
docker:x:970:user
libvirt:x:966:user,root
libvirtdbus:x:969:root,user

Anyway, it's probably this: /usr/bin/dockerd -H fd://

xhost +

echo ${DISPLAY}

What desktop environment are you using? Are you running NAS or anything?

[shivangp76]

Ah, I did cat /etc/group and realized the kvm group was there, but I just wasn't in it, so I added myself. FYI the permissions for the groups are

$ cat /etc/group | grep -e kvm -e docker -e libvirt
kvm:x:992:shivang
libvirt:x:972:shivang
docker:x:971:shivang

So now the Catalina image command you sent works and launches. There are still all of those alsa errors, but I can at least boot into Catalina and it works perfectly. However, I'm still getting the same error message for the original image I tried. What does this do exactly: /usr/bin/dockerd -H fd://? I couldn't get it to run, but I'll look more into it.

Also

$ xhost +
access control disabled, clients can connect from any host
$ echo ${DISPLAY}
:0

I'm not using a desktop environment - just a window manager (dwm in case you were wondering). Not running NAS.

Everything is fine, Alsa errors are normal

[shivangp76]

So I still couldn't get Pre-Made Non-Headless Image working (docker run -it \ --device /dev/kvm \ -p 50922:10022 \ -v /tmp/.X11-unix:/tmp/.X11-unix \ -e "DISPLAY=${DISPLAY:-:0.0}" \ sickcodes/docker-osx:auto), but the catalina and big-sur images work, so I guess I'll just make do with that. Thank you so much for the help!
