Re: Deploying vApp from template - what's this err...

smackdaddy99 · ‎06-20-2016

Hi there forum!

I'm attempting to deploy a vApp from a template and customize the VM's network config during instantiation.

I've followed the example documentation pretty slavishly as per the documentation site for my vcloud director version here: http://pubs.vmware.com/vcd-56/index.jsp#com.vmware.vcloud.api.doc_56/GUID-BF9B790D-512E-4EA1-99E8-68...

But I'm getting an error from vCLoud Director that suggests the example is bogus, thus:

Here is my XML payload - what is actually wrong with it?:

I think you need the <ovf:Info> element, as shown here (from Create a vApp From a Template)

<ovf:Info>Configuration parameters for logical networks</ovf:Info>

<FenceMode>bridged</FenceMode>

</Configuration>

</NetworkConfig>

</NetworkConfigSection>

I never really figured out why vCloud Director didn't accept the payload in my original post. The documentation is clearly not trustworthy, I'm sorry to say.

I finally got it to work with this (it's an eRuby template, so the #{variables} indicate interpolated values from the ruby program):

I hope this is helpful to someone else.

Thanks for posting this. It works for me as well. The example in the documentation also works for me, though it doesn't do exactly the same thing as the sample you posted here. We'll take a closer look at how our example could be improved, sine we really want to documentation to be trustworthy (and correct).
