Aria Orchestrator: Find the hostname of the Orchestrator server which is running a workflow, within its JavaScript scripting element.

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

• Get Orchestrator hostname in vRO workflow script
• Guidance on how to use a workflow to get the hostname of the current Orchestrator.

Environment

• VMware Aria Automation Orchestrator 8.x

Resolution

Here are some approaches which you can use to get the Orchestrator hostname:

1. One approach uses the vRA plugin to get the hostname. Ensure that the Aria Automation plugin is installed and the host is set as Default:
   • hostname = VraHostManager.defaultHostData.vraHost;
System.log("Hostname = '" + hostname + "'");
     
     
2. The second approach requires you to first enable the com.vmware.js.allow-local-process property to allow Linux processes to be executed in the vco-app (Orchestrator) pod.
   
   1. CLI command:
vracli vro properties set -k com.vmware.js.allow-local-process -v true
      
      
   2. Workflow JavaScript:
      var cmd = new Command('printenv');
cmd.execute(true);
var out = cmd.output;
var prop = "-Dvco.app.hostname=";
var posStart = out.indexOf(prop);
var posSpace = out.indexOf(" ", posStart);
var hostname = out.substring(posStart + prop.length, posSpace);
System.log("Hostname = '" + hostname + "'");
      
      
3. It is also possible to create a custom configuration element on each Orchestrator host which contains its hostname, and then query this in the workflow.
