CSE 2.0 : Couldn't initialize cluster

[Vijendrasi]

CSE 2.0
CSE server OS -> Photon OS : 3.0
VCD version : 9.5

Do we need internet connection for initialization of cluster ?

Yes. Internet connection is required as part of the initialization process and executing customization scripts on the cluster, node creation etc.

I have used older version of CSE 1.2.5 that time internet connection was required for during template creation process.
while running vcd cse cluster create CSE-UB-CLU01 --network ORG-NET-EXT01 --nodes 1 command internet connection was never required for ORG-NET-EXT01 network. I am sure it must be remain same in CSE 2.0 as well. It is not possible that all the workload vms will have internet connectivity.
