How to Retrieve Hostname in vRealize Orchestrator Workflows

To get the vRealize Orchestrator (vRO) appliance’s hostname using JavaScript within a vRO workflow, there is no official API call for this purpose, but there are practical workarounds:

Method 1: Parse Environment Variables

In vRO 8.x (containerized), you might be able to extract the hostname from JVM arguments in the environment:

Prerequisite: Enable local process execution.

JavaScript

var com = new Command(["printenv", "|", "fgrep", "JVM_OPTS"]);
var res = com.execute(true); // makes the call blocking
var output = com.output;
var nodeName = output.match(/-Dvco.app.hostname=([^\s]+)/)[1];
System.log('vRO Hostname: ' + nodeName); // vRO Hostname: vra_fqdn.domain.local

Method 2: Extract embedded vRO Hostname from vRA Plugin

If local command execution is not permitted, you can try to extract the hostname or IP from the vRA Plugin class :

JavaScript

System.log(VraHostManager.defaultHostData.vraHost); // https://vra_fqdn.domain.local

Getting IP from FQDN

JavaScript

System.log(System.resolveHostName("vra_fqdn.domain.local")); // 10.242.1.8
System.log(System.resolveIpAddress("10.242.1.8")); //10-242-1-8.kubernetes.default.svc.cluster.local

Summary Table

Method	Reliability	Notes
Command	High	Needs local process enabled
vRA Plugin	Low	May return IP or hostname

Choose the method that matches your vRO configuration and security policy.
If you cannot enable local process execution, the vRA host url extraction is the safest alternative.
