ERROR: Docker socket is missing? Please bind /var/run/docker.sock in your compose file

I’m a beginner in Docker and know the basics.
I’m trying to run CasaOS in Docker on Windows, and I’m getting the following error:

2025-03-22 21:31:14 ❯ ERROR: Docker socket is missing? Please bind /var/run/docker.sock in your compose file.
2025-03-22 21:31:14 ❯ Starting CasaOS for Docker v0.4.15...
2025-03-22 21:31:14 ❯ For support visit https://github.com/dockur/casa/issues

I’ve already searched in many places and couldn’t find a solution. Can anyone help me?

Hi

Please explain how you are running that container, is this using a docker run command (if so you need to provide the -v flag) or a compose.yaml file (if so you need to provide a volume).

Search for mounting docker.sock on Ggle and you will pléthore of links.

Please note : sharing the docker socket is dangerous. Are you absolutely sure you need to do so ?

Have you tried the image description that shows how you should start a container?

I assume you just used Docker Desktop and clicked on the image to start the container using only the GUI.
