Dockerizing OpenClaw: The Ultimate Sandboxing Guide
Protect your host machine from rogue agent commands. A complete guide to setting up OpenClaw with Docker-in-Docker (dind) for secure, isolated execution.
OpenClaw is powerful because it uses your local tools. That's also why it's dangerous. A misaligned agent running rm -rf is not a theoretical risk. The solution is Sandboxing.
The 'Non-Main' Strategy
OpenClaw supports a hybrid mode. You can trust the "Main" session (your direct control), but force all other sessions (Discord users, sub-agents) into containers.
// openclaw.json
{
"agents": {
"defaults": {
"sandbox": {
"mode": "non-main",
"image": "openclaw/sandbox:latest"
}
}
}
}This spins up an ephemeral Docker container for every new task. The agent can install packages, mess up files, and crash the OS—inside the container. Your host remains pristine.
