i tried to reproduce the issue with your config but can't. somehow port 22 isn't exposed for the workspace on your end. can you run:

docker container ls --format "table {{.ID}}\t{{.Names}}\t{{.Ports}}" -a

and paste the output? mine looks like this:

as you can see port 22 is correctly exposed. also what OS are you running tesseract on?

do you get the same error if you create another workspace? can you try fedora 40 with openssh for the base template?

it says the container is not running: <img width="503" alt="Screenshot 2024-12-05 at 17 26 23" src="https://github.com/user-attachments/assets/489b6a3f-c34d-4a2b-a620-fe63768c7b82"> do you get the same error if you create another workspace? can you try `fedora 40 with openssh` for the base template?

i am struggling to see why docker is not reporting the host port that is mapped to the container port even though it knows that port 22 is exposed on the container side.

the container looks like its running in Docker desktop
image
If i perform a create again, it asks me to rename the existing container to continue
image
If I try with a new workspace name, its back to the failed to bind ssh port toast error

do you have sshd daemon running on your host machine?
the app targets localhost in my case and I dont know if sshd is a required prerequisite

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

for me, sudo lsof -i :2222 returns nothing and port 2222 on the host is not mapped to port 22 inside the container

no, on paper you don't need sshd on the host to have it working, but can you try starting sshd and see if it works?

the issue here is that docker inspect is not returning the exposed port on host for some reason. i am still failing to understand why that's the case.

can you also run docker version and paste the output here?

it may be because Docker does not automatically bind a host port to a container port unless explicitly requested during container creation, and inspect.NetworkSettings.Ports is empty

Need to ensure that mgr.dockerClient.ContainerCreate includes -p or -P

sample:

// modified from https://github.com/kennethnym/tesseract/blob/master/internal/workspace/workspace_manager.go#L191-L199

inspect, err := mgr.dockerClient.ContainerInspect(ctx, res.ID)
if err != nil {
    return nil, err
}

ports, found := inspect.NetworkSettings.Ports[containerSSHPort]
if !found || len(ports) == 0 {
    return nil, errors.New("failed to bind SSH port for container")
}

hostPort := ports[0].HostPort
if hostPort == "" {
    return nil, errors.New("host port mapping is empty")
}

return hostPort, nil
it __may_ be_ because Docker does not automatically bind a host port to a container port unless explicitly requested during container creation, and `inspect.NetworkSettings.Ports` is empty Need to ensure that `mgr.dockerClient.ContainerCreate` includes `-p` or `-P` sample: ```go // modified from https://github.com/kennethnym/tesseract/blob/master/internal/workspace/workspace_manager.go#L191-L199 inspect, err := mgr.dockerClient.ContainerInspect(ctx, res.ID) if err != nil { return nil, err } ports, found := inspect.NetworkSettings.Ports[containerSSHPort] if !found || len(ports) == 0 { return nil, errors.New("failed to bind SSH port for container") } hostPort := ports[0].HostPort if hostPort == "" { return nil, errors.New("host port mapping is empty") } return hostPort, nil ```
