Hello,
i using hazelcast (tcp discovery) into a docker swarm cluster.

According to official documentation (https://docs.docker.com/engine/swarm/networking/) swarm assign a VIP and a "fisical" IP for every service.

When a hazelcast member try to connect to another i have a conflict IP because hazelcast match any service with 2 different IP (VIP and IP)

How to resolve it?

I temporary fix with custom discovery strategy using swarm API and SimpleDiscoveryNode with only virtual IP (without host name)

Address address = new Address(null, InetAddress.getByName(ip), NetworkConfig.DEFAULT_PORT); servers.add(new SimpleDiscoveryNode(address));

It is working perfectly!!!!

#11548

mmedenjak pushed a commit to mmedenjak/hazelcast that referenced this issue Oct 11, 2017
Add bind address provider SPI
0bc27a8 
Adds a new SPI for defining the addresses that the hazelcast instance
will bind to and the address which will be advertised to other members
on which they can bind to.
This SPI will allow for implementations for different environments in
which the default address picker does not pick suitable addresses and
manually configuring the public address provides additional complexity
for deploying hazelcast.

The SPI does not necessarily fix all current issues when deploying
hazelcast but provides the user with a way to avoid these issues by
either providing their own implementation or using some implementation
that hazelcast will provide in the future.

@Fabryprog @lokinell @bitsofinfo
there is a new SPI that has just been merged and which will be released in the 3.9 version. It will allow you to define the bind and public address when starting the hazelcast instance and if used correctly it can be used to avoid issues when forming a cluster.
For now you will have to use the SPI yourself and write an implementation which will fix your issue but we are planning on releasing implementations of our own which will be bundled into plugins such as the docker or AWS plugin for easier deployment.
Please check out the new SPI:
https://github.com/hazelcast/hazelcast/blob/3cede71cad1fe87312f0901ff77f903ed2d4383d/hazelcast/src/main/java/com/hazelcast/spi/MemberAddressProvider.java
Please create a new issue or reopen this one if this does not suit your use case.
