is this not already a feature? or are you asking for something similar to docker-compose where you can run more than one container in a railway project?

Mykal Machon: no i believe this is asking for being able to spawn a docker daemon inside of a project

Milo: indeed

What would be a use case of this?

One use case that I'm trying to do is deploying https://coder.com - it could use Railway services with a lot of configuration, but it would be significantly easier to use the built-in Docker template.

I would need this too so I can use Docker inside code-server. Any news?

Still not possible and it does not seem like there are currently any plans or interest in enabling the privileges needed to achieve this.

Would it work with Podman?

It would work with their current Docker runtime or their upcoming Podman runtime, but it's not a question of whether it can be done, it's a question of whether they want to allow it, and the answer to that seems like a No for right now.

Got it thanks! I guess it's to push for purchasing coder.com service instead of self-hosting

Just found this in coder.com FAQ

What does this mean in the context of Railway?

You simply can't do such things on Railway.

I was working on a Coder template for Railway, but I was unfortunately stopped by some issues with the community Terraform provider.

Templates don't use terraform, so I'm not sure what you where doing there, and isn't there already a Coder template?

Not a Railway template, a Coder template. There's a Coder template that runs the dashboard on Railway, but I ran into trouble trying to get Coder to provision workspaces on Railway, for which it uses Terraform.

Ah gotcha.

hello, I need docker in docker too, so I can be able to run Gitlab runner on Railway to build jobs for Gitlab CI piplines. Is docker in docker possible in the near future?

This is my conclusion because there is no official documentation on this topic, and I have summarized here:

Railway doesn't officially document this, but these forum posts confirm it doesn't support nested containerization—Docker and Podman can't run within projects. This appears to be a deliberate security measure: Railway enforces strict container isolation by prohibiting privileged containers, blocking Docker daemon access, and preventing container runtime installations.
