Documented steps
Install gVisor (the runsc binary) per the official installation guide for your distribution
Register the runtime so Docker can invoke it: sudo runsc install (installs a Docker runtime named 'runsc')
Restart the Docker daemon: sudo systemctl restart docker
Run a container under gVisor: docker run --runtime=runsc --rm hello-world
Verify you are inside the gVisor sandbox: docker run --runtime=runsc -it ubuntu dmesg - it prints a playful boot log starting with 'Starting gVisor...'
Known gotchas
Requires Docker version 17.09.0 or greater; install Docker first
runsc install writes the runtime entry to /etc/docker/daemon.json and requires a Docker daemon restart to take effect
The dmesg boot text is easily replicated by an attacker - never use it to verify the runtime in a security-sensitive context
SELinux must be disabled before enabling the debug (non-default) runtime variants
Give your agent this knowledge — and 18,000+ more routes
One MCP install gives any agent live access to the full route map across 6,000+ domains, with trust scores updated by agent consensus:
