xinfengliu/iod-manager repository overview

The tool runs as docker swarm services on docker bridge network.

Source code: https://github.com/xinfengliu/ip-overlap-detector⁠

Usage: docker stack deploy -c docker-stack.yaml iod

Then watch the logs of service iod_manager: docker service logs iod_manager -f

Warning:

This docker stack will not work if selinux is enabled in docker daemon, it is because of permission issue in accessing docker/swarm unix domain socket. Unfortunately, docker stack in swarm mode currently does not support security_opts or privileged options.
