Docker in Docker with sysbox cant find the deamon

Hello, I have installed coder with docker-compose. Also installed sysbox on the host that coder runs. I am trying to get docker to work inside the docker container but i get cannot connect to the docker daemon at unix:///var/run/docker.sock. is the docker daemon running? My dockerfile is the following:

Attached is the main.tf. Also when i run docker inspect --format='{{.HostConfig.Runtime}}' coder-workspace i get sysbox-runc so i guess that part is configured properly.

Phorcys•2mo ago

@anubis what's the error?

anubisOP•2mo ago

@Phorcys sorry it seems i pasted the wrong thing. the error is: cannot connect to the docker daemon at unix:///var/run/docker.sock. is the docker daemon running?

Phorcys•2mo ago

oh okay, so yeah you still have to use start docker manually if you don't have systemd sudo dockerd otherwise install systemd, or just use the coder/enterprise-base image as your base image

anubisOP•2mo ago

Oh my god, never thought about it... I will try when i get in the office. Will update you. Thank you. Issue got resolved. Thank you @Phorcys @Phorcys I am trying to use the codercom/enterprise-base:ubuntu but i get the same error if i dont start docker manually and when i run systemctl i get the following error:

System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down

System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down

I run it with the following command: sudo docker run --runtime=sysbox-runc -it --privileged codercom/enterprise-base:ubuntu

add dockerd & in terraform config with log redirection systemd wont work normally in container

anubisOP•2mo ago

if i run the official sysbox image with systemd and docker (nestybox/ubuntu-bionic-systemd-docker) then it works fine (both docker and systemctl but i have to login as a user. If i add the part to add the coder user then it fails. Also my biggest confusion comes from the documentation that says that you can have systemd in docker but only refers to the Kubernetes deployment. https://coder.com/docs/templates/docker-in-workspaces#systemd-in-docker

Docker in workspaces - Coder Docs

Phorcys•2mo ago

it will with Sysbox

oh yeah? i am using sysbox too, but i am just starting the daemon in the terraform file see this https://pastebin.com/AwcBiH3L

yes i did the same in the end, but cant get systemd to work. when i use the codercom image it doesnt start and if i use the sysbox image i need to use the admin account

深雪•2mo ago

i assue u mean u need sudo or su root to use docker if you check my dockerfile, the coder user is added to the docker group RUN useradd -G sudo,docker --no-create-home --shell /bin/bash ${USER} \ in this way, you dont need sudo or root to run docker commands

anubisOP•2mo ago

No, I have the same setup as you do now. That works fine. Docker works as expected. The issue is that systemd wont start and will give an error about the user if i use the codercom image. If i use the sysbox image it works fine but only with the admin:admin user

Phorcys•2mo ago

i don't have an immediate answer as i've never tried it but yeah for now you can just start dockerd manually i'll play around with it to see how we can have systemd-in-docker working with Coder

深雪•2mo ago

whats the error if u run systemctl with not admin acc? useradd --create-home --shell /bin/bash coder && echo "admin:admin" | chpasswd && adduser admin sudo docker try this in dockerfile

anubisOP•2mo ago

that is the error with the codercom image.

深雪•2mo ago

hm, i got this error too same with sudo what did u do to make systemctl work with sudo?

anubisOP•2mo ago

i havent managed to get it work. the only case where it works is if you use this image https://github.com/nestybox/dockerfiles/blob/master/ubuntu-bionic-systemd/Dockerfile . The issue is that if i add the part for creating a user (instead of using the default admin:admin) then i get errors again.
