docker-swarm-keepalived's Issues

Compile error after updating to 0.2.4

I received the below errors after updating to the recent 0.2.4 update. Works when I revert to 0.2.3.

Thanks for taking a look at this -- Let me know if I can provide any further logs or information to assist in troubleshooting!

Blocks Docker's Overlay Network

I have noticed when running this service on any node in a docker swarm, the docker overlay network begins to behave very strangely. For instance, containers are no longer able to talk to each other across nodes or locally. Problem goes away when docker-swarm-keepalived service is stopped.

I am not really sure what to provide to help describe the problem as clusters and swarms can quickly become pretty complex.

Worker nodes

It appears that if I have keepalived on the worker nodes priority and unicast does not get set properly because we using the docker node ls command to populate those. But if we are on a worker node we don't have access to that information. Can we confirm this only works if we are using this repo on manager nodes?

Any idea?

multi aarch working?

I have a swarm cluster with different architectures. Could we made this running? On x86 the docker container is deployed but aarch64 (RPI) it says

unsupported platform on 1 node
