1. Installation

$ git clone git@github.com:openclaw/openclaw.git 

# go to openclaw directory
$ ./docker-setup.sh

Change docker-compose.yml.
I added extra_hosts : "host.docker.internal:host-gateway".

services:
  openclaw-gateway:
    image: ${OPENCLAW_IMAGE:-openclaw:local}
    extra_hosts:
      - "host.docker.internal:host-gateway"

install brew manually.
it seesm the docker container doesn’t have brew and during installation it fails if brew is not installed.

mkdir ~/.linuxbrew && curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C ~/.linuxbrew

# set up environment variables 
echo 'export PATH="$HOME/.linuxbrew/bin:$HOME/.linuxbrew/sbin:$PATH"' >> ~/.bashrc
echo 'export MANPATH="$HOME/.linuxbrew/share/man:$MANPATH"' >> ~/.bashrc
echo 'export INFOPATH="$HOME/.linuxbrew/share/info:$INFOPATH"' >> ~/.bashrc

Model Provider

vLLM

you can serve local LLM like this.

vllm serve openai/gpt-oss-20b \
    --host 127.0.0.1 \
    --port 8045 \
    --tensor-parallel-size 1 \
    --gpu-memory-utilization 0.3 \
    --trust-remote-code \
    --async-scheduling \
    --max-num-batched-tokens 8192 \
    --max-model-len 35096 \
    --api-key 1234

connect to Docker terminal and then change the connection information like this.
no need to restart the openclaw container.

# change address to host.docker.internal
sed -i 's/127.0.0.1/host.docker.internal/' ~/.openclaw/openclaw.json

# change vLLM API key (1234)
sed -i 's/"VLLM_API_KEY"/"1234"/' ~/.openclaw/openclaw.json

Setup OpenClaw Gateway

connect to Docker terminal and you can get a gateway token

$ echo $OPENCLAW_GATEWAY_TOKEN
05c5df07ef01<eradicated>

http://127.0.0.1:18789/overview
in Gateway Access, put the token in Gateway Token

Token Issue

If you happen to run ./docker-setup.sh multiple times, it generates a new random gateway token.
this creates a mismatch between .env and ~/.openclaw/openclaw.json

$ grep OPENCLAW_GATEWAY_TOKEN .env
OPENCLAW_GATEWAY_TOKEN=05c5df0<eradicated>

$ grep -o '"token": "[^"]*"' ~/.openclaw/openclaw.json
"token": "05c5df0<eradicated>"

if both configurations are different, you need to update ~/.openclaw/openclaw.json file to match the .env token
and then restart docker

$ docker restart openclaw-openclaw-gateway-1
