The recent releases of OpenClaw have made running it on docker/podman much easier. I've been running it on a stand alone Lenovo Thinkcentre running inside docker. For my needs the setup works well. There are some limitations like hardware and filesystem access with my workstation (macbook) but largely solvable and I like the isolation. For locking it down further, particularly on the network level someone recently released https://nono.sh/ which seems promising. I've been using https://clawchat.dev/ on my macbook for chatting with the openclaw agent. It is rough around the edges but gets the job done.
