macvlan/ipvlan/overlay network fix ip addresses in swarm clusters

[MK796]

Tell us about your request
Make the three mentioned network types compatible with swarm.

Which service(s) is this request for?
Docker Swarm

Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?
Actual state is inflexible.

Yes I now what the original goals were for swarm. But some use cases need fix IPs within the hosts network or within an overlay network. Not every service is able to run "clustered".

The actual state somehow counteracts the swarm cluster purpose.

Are you currently working around the issue?
An extremely inelegant combination of keepalived and a lb for example haproxy is needed to achieve host level fix IPs for containers.

Getting fix IPs in an overlay network is almost impossible.

Additional context
Close the gap between docker standalone and swarm networking features and integration.
