I found that my network adapters are not eth0/1 as your scripts have. My network adapter is named ens160. When I created the VM in ESXi that was the default name it was being given.

You can change the interface that is being used for internal cluster communication by setting the galera_cluster_interface variable. Putting galera_cluster_interface: ens160in e.g. group_vars/all should solve the issue in your case.
