The IP of my kURL cluster changed, it is a single master node, how do I recover from this?
If this is a Multi-Master node, this process is as simple as removing the node which the IP changed and add a new node. Same process goes for the worker nodes.
If the IP on a single master node changed, then there is no easy way to recover. In addition to changing the TLS certs there has to be various configurations changed as well, at the moment it is not possible to change the IP of the single-master node.
