This is a Node.js module to connect to VMware vCenter servers and/or ESXi hosts and perform operations.

node-vsphere

This module is not yet finished and still under development!

This is a Node.js module to connect to VMware vCenter servers and/or ESXi hosts and perform operations using the vSphere Web Services API.

This module is dependent upon node-vsphere-soap which handles the low-level SOAP WSDL calls to the vSphere API. This module should be referenced in your projects, not node-vsphere-soap, so you can avoid making lower-level calls directly to vSphere Web Services.

This is very much in alpha.

Version

0.0.1

Installation

$ npm install vsphere --save

Sample Code

examples directory

Check out the examples in that directory, which include how to run power operations on VMs and how to grab the properties of ManagedObjectReferences.

To connect to a vCenter server:

var Vsphere = require('vsphere');
var vc = new Vsphere.Client(host, user, password, sslVerify);
vc.once('ready', function() {
  // perform work here
});
vc.once('error', function(err) {
  // handle error here
});

Arguments

• host = hostname or IP of vCenter/ESX/ESXi server
• user = username
• password = password
• sslVerify = true|false - set to false if you have self-signed/unverified certificates

Events

• ready = emits when session authenticated with server
• error = emits when there's an error
  • err contains the error

Client instance variables

• serviceContent - ServiceContent object retrieved by RetrieveServiceContent API call
• userName - username of authenticated user
• fullName - full name of authenticated user

Available methods:

There are examples here for now, until more formal documentation is put together

var vcCmd = vc.runCommand( commandToRun, arguments );
vcCmd.once('result', function( result, raw, soapHeader) {
  // handle results
});
vcCmd.once('error', function( err) {
  // handle errors
});

var rootFolder = vc.serviceContent.rootFolder;

vc.getMORefsInContainerByType( rootFolder, 'VirtualMachine')

vc.getMORefsInContainerByTypeName( rootFolder, 'VirtualMachine', 'myVM')

vc.getMORefProperties( MORef )
vc.getMORefProperties( MORef, propList )

vc.getMORefsInContainerByTypePropertyArray( rootFolder, 'VirtualMachine', ['name', 'config'])

vc.getVMinContainerPowerState( rootFolder )
.once('result', function( result) {
  /*
  result = [{ obj: { attributes: { type: 'VirtualMachine' }, '$value': '4' },
            name: 'testvm-win',
            powerState: 'poweredOff' }, ...]
  */
});
.once('error', function( err) {
  // handle errors
});

vc.powerOpVMByName( vmName, powerOp)
/*
vmName can be a string (for a single VM) or an array of strings (for multiple VMs)
powerOp is one of ['powerOn', 'powerOff', 'reset', 'standby', 'shutdown', 'reboot', 'suspend']
*/

vc.waitForValues( MORef, filterProps, endWaitProps, expectedVals)
/*
emits result when the specified properties of a ManagedObjectReference 
MORef = ManagedObject to monitor
filterProps = properties to filter/retrieve from MORef
endWaitProps = property to monitor
expectedVals = values of property to monitor (endWaitProps) that will trigger command to emit result
*/

/* usage example for powering on and off a VMa VM */
vc.powerOpVMByName( _.sample(TestVars.testVMs), 'powerOn')
  .once('result', function(powerOnResult) {
    // ensure VM PowerOn task successfully fired
    expect(powerOnResult[0].result['$value']).to.be.equal('success');
    // get the Virtual Machine ManagedObjectReference
    var vmObj = powerOnResult[0].obj;
    vc.waitForValues( vmObj, 'summary.runtime.powerState', 'powerState', 'poweredOn')
    .once('result', function(result) {
      // verify VM is powered on
      expect(result['summary.runtime.powerState']['$value']).to.be.equal('poweredOn');

      // fire powerOff command
      vc.powerOpVMByMORef( vmObj, 'powerOff')
      .once('result', function(powerOffResult) {

        // ensure VM PowerOff task successfully fired
        expect(powerOffResult[0].result['$value']).to.be.equal('success');

        vc.waitForValues( vmObj, 'summary.runtime.powerState', 'powerState', 'poweredOff')
        .once('result', function(result) {
          // verify VM is powered off
          expect(result['summary.runtime.powerState']['$value']).to.be.equal('poweredOff');
          done();
        })
        .once('error', function(err) {
        console.error(err);
        });         
      })
      .once('error', function(err) {
        console.error(err);
      });
    })
    .once('error', function(err) {
      console.error(err);
    });
  })
  .once('error', function(err) {
    console.error(err);
  });

Events

• result = emits when session authenticated with server
  • result contains the JSON-formatted result from the server
  • raw contains the raw SOAP XML response from the server
  • soapHeader contains any soapHeaders from the server
• error = emits when there's an error
  • err contains the error

Make sure you check out tests/vsphere.test.js for examples on how to create commands to run

Development

node-vsphere-soap uses a number of open source projects to work properly:

• node.js - evented I/O for the backend
• node-vsphere-soap - SOAP/WSDL vSphere/ESXi client for Node.js
• lodash - for quickly manipulating JSON
• lab - testing engine
• code - assertion engine used with lab

Want to contribute? Great!

Todo's

• Write More Tests
• Create Travis CI test harness with a fake vCenter Instance
• Add Code Comments

Testing

I have been testing on a Mac with node v0.10.36 and both ESXi and vCenter 5.5.

To edit tests, edit the file test/vsphere.test.js

To point the module at your own vCenter/ESXi host, edit config-test.stub.js and save it as config-test.js

To run test scripts:

$ npm test
