I have setup a local (on-prem) UCP cluster (1 controller + 2 replicas + 2 nodes). They are on a private 192.168.1.x network.
For test purposes I wanted to add a node in a public cloud (could be AWS, Azure, GCC, DO, whathaveyou) but I don’t have a peering/VPN between my on-prem setup and any of these public clouds nor I can expose my UCP cluster on the Internet. In other words the UCP cluster can reach out to the additional node in the public cloud but the additional node in the public cloud CANNOT reach out to the UCP cluster.
I was hoping there was a way to “push” the configuration of a node from the UCP cluster to the node but the only procedure I see documented is running the join on the node and declare the UCP controller (a process I cannot complete because of the limitation above).
I totally get the latency issues and all that (e.g. Add nodes in different region to UCP) but I was wondering if, only for test purposes, this could be accomplished with the network setup as described.
