 Mapping `docker.sock` is a potential security liability because docker has root access on the host and any process that has full access to `docker.sock` would also have root access on the host. Docker api has no built-in way to set limitations on access, however you can use a proxy for the `docker.sock` via a solution like [our docker socket proxy](https://github.com/linuxserver/docker-socket-proxy), which adds the ability to limit access. Then you would just set `DOCKER_HOST=` environment variable to point to the proxy address.

 ```yaml
   dockerproxy:
     image: lscr.io/linuxserver/socket-proxy:latest
     container_name: dockerproxy
-    volumes:
-      - /var/run/docker.sock:/var/run/docker.sock:ro
-    restart: unless-stopped
     environment:
       - CONTAINERS=1
       - POST=0

 ```
-The above config for instance would allow read only access to the docker api. Then the env var in the container with the docker mod can be set as `DOCKER_HOST=dockerproxy`. This will allow the container to retrieve info on other containers, but it won't be allowed to spin up new containers. With the proxy, you can fine tune the permissions very easily.
