support manually assigning IPs to nodes

[volfco]

Is there a way to statically assign IPs to a specific node?

Currently no. The idea is to keep the management overhead to a minimum.

Do you have a concrete use-case for which the /etc/hosts handling is not a solution?

[volfco]

The three I have are:

1. All of the software I've written doesn't have support for taking hostnames- it expects an IP address

2. Exposing the mesh network to private networks is impossible due to the need to setup static routes on the host- which you can't do when you don't know the IP address of the routing nodes.

3. Half the environment is managed via Salt/Ansible, and half dynamic. There is no way for a host not in the mesh to talk to one that is (assuming routing is setup correctly)

[costela]

I don't really have an answer for 1.

As for 2 and 3: this use-case isn't currently supported and probably wouldn't work as you expect: if you're talking about routing, you're probably thinking of adding a sort of "gateway" to the mesh on the statically managed side. Even if you had static IPs, the private nodes would be able to route traffic to the mesh, but the mesh would not be able to route them back.

I suspect #8 might a more productive direction. In this case you'd just add all your private nodes to the mesh and let them talk directly to each other. Unfortunately we're not quite there yet.

2/3 can be addresses by adding a static route to every host (via configuration management)

[costela]

If you're already using config management to add the static route to all dynamic hosts, you could probably collect their IPs and add the outgoing routes on the static side.

But again: we're probably outside the realm of what wesher was meant to solve.

I would endorse the idea of static IPs. I am solving the same issue (2/3, routing traffic to another server based on subnet) and unfortunately, there is no "easy" way how to set up default gateway based on hostname.

I wanted to move from "pure" wireguard to something more complex and I thought wesher could solve this.

I'd also really like this because we have software that search for applications running on specific internal IPs and want to specify them for each server. (We want to have the same network layout with the same hosts for different regions)
