If you want to see 3 meta instances in nebula, the problem is that you are using DNS incorrectly. When the three IP addresses are located behind the same domain, only one exact IP address will be obtained for each analysis. In the absence of a specific policy, a domain will only continue to return a specific IP when it is parsed. Therefore you will only get one meta node. Please set different domain names for the 3 meta nodes and record them in the meta config file. Or use 3 meta IP addresses.

@Sandeep we should never do this (n-1 host:ip) for nebulagraph services, inside the cluster the instance of processes are identified with its host:port.

Oh Okay. Thanks both for the clarification
