How to install and run docker with nix

Question

I'm using Debian on WSL. Nix is already install.

I install docker with this command:

nix-env -iA nixpkgs.docker

I want to start the daemon :

systemctl start docker

Failed to connect to bus: No such file or directory

update

FYI $XDG_RUNTIME_DIR= /mnt/wslg/runtime-dir $UID=1000 $DBUS_SESSION_BUS_ADDRESS has no value

ls -l /mnt/wslg/runtime-dir

drwx------ 4 pierre pierre 120 Dec 26 00:41 runtime-dir

I can access the bus. But I need to use sudo

sudo systemctl start docker

Now I have this problem

Failed to start docker.service: Unit docker.service not found.

I think docker.service is this file: /etc/systemd/system/docker.service

But it doesn't exist on my OS. I'Ve tried to uninstall and reinstall docker with nix. To no avails

I think that it is linked:

https://discourse.nixos.org/t/docker-packages-systemd-unit-files-dont-work-on-ubuntu/12160

sudo cp ~/.nix-profile/etc/systemd/system/docker.service /etc/systemd/system/docker.service

sudo cp ~/.nix-profile/etc/systemd/system/docker.sock /var/run/docker.sock

sudo systemctl enable docker


 Failed to start docker.service: Unit docker.socket not found.

Failed to start docker.service: Unit docker.socket not found.

After reading this link, I use this command in order to the know where I should replace docker.socket file. :

 systemctl list-sockets --all

But no docker.socket is listed

**update

I have made all the commands from scratch. Now I have this problem A dependency job for docker.service failed. See 'journalctl -xe' for details.

Answer 1

If I understood the problem correctly, you have to set your XDG_RUNTIME_DIR manually (because /run/user/... is sometimes owned by some other user?? (Not quite sure to be honest)):

So can you try to set XDG_RUNTIME_DIR = "/run/user/$UID" and then starting nix again?

If that doesn't work you maybe have to set DBUS_SESSION_BUS_ADDRESS as well to DBUS_SESSION_BUS_ADDRESS="unix:path=/run/user/$UID/bus".

You can find a similar thread to yours here: https://superuser.com/questions/1561076/systemctl-user-failed-to-connect-to-bus-no-such-file-or-directory-debian-9

Did that help/fixed your problem?

Answer 2

You must look for directory, use cd .. and go to /bin/, there is your program, then start use ./docker or systemctl start docker.

Answer 3

sudo groupadd docker
sudo chgrp docker docker.sock
sudo systemctl start docker

No error message
