I have every suggested/needed configuration in the kernel, but swarm overlay networking not working. Reproducible: Always Steps to Reproduce: 1. emerge docker 2. configure all kernel options as suggested 3. create a service in docker swarm mode opening a port (on overlay network by default) Actual Results: I can't access the service: Connection refused Expected Results: Access the service on the docker swarm overlay network Lots of google searching lead me to this thread: https://github.com/scaleway/kernel-tools/issues/293 I was not sure if it is relevant, but I tried it and it helped!
Created attachment 468712 [details, diff] Apply on the ebuild to extend the config check dependency
