Description
In Docker Swarm, the docker socket only exists on manager nodes, so this was failing sporadically for me without much explanation until I realized it was whenever the proxy was deployed to a worker node. Here are the constraints required in docker compose format:
deploy:
mode: global
placement:
constraints:
- node.role == manager

Research direction
Locate the Docker Swarm deployment documentation and review how proxy placement is currently described. Document that the proxy must run on manager nodes because the Docker socket is only available there, including the manager-node placement constraints shown in the issue. Done means the deployment guidance explains the worker-node failure and the required constraint.
