Hi,

hostname +1

It makes node migration easy.

Thanks,

&gt; Hi,
&gt;
&gt; Today Julian and I discussed some logic of the cluster module.
&gt; Both of us feel it strange that we replace the hostname to IP before a
&gt; cluster node starts up.
&gt; I think it is not a very common way.
&gt;
&gt; hostname sometimes is very very helpful. For example, in K8S
&gt; environment, a node's hostname never changes, but its IP may change.
&gt;
&gt; Best,
