we have two datacenters and every datacenter has three networks. Every network has its own Consul and Vault cluster. If I would deploy Nomad the normal way, I would have to create six nodes per network: 3 clients, 3 servers.
My idea was now, if it is possible to install just 3 or 5 servers to manage all clients in every DC and network, but configure them, to use the dedicated Consul / Vault cluster inside the networks.
DC1 → LAN → Consul / Vault
DC1 → DMZ-> Consul / Vault
DC1 → EXT → Consul / Vault
Or is that not possible, and I need to create Nomad clusters (3 servers, 3 clients) per network and configure them to use the Consul and Vault, which we have per network ?
