I’m working in the vOnecloud 3.2.1 environment and am having issues with instantiating from template.

I have declared 3 new ‘mandatory’ variables in the templates context:

> [oneadmin@machine root]$ onetemplate show 4  
> TEMPLATE 4 INFORMATION  
> ID : 4  
> NAME : opennebula-rhel-7.6-1902.2  
> USER : oneadmin

> DOMAIN=“$DOMAIN”,

> TYPE=“VNC” ]  
> HYPERVISOR=“vcenter”  
> INPUTS\_ORDER=“DATACENTER,DOMAIN,INSTALL\_APP”  
> MEMORY=“2048”  
> MEMORY\_UNIT\_COST=“MB”  
> NIC=[  
> NETWORK\_ID=“0”,

> onetemplate instantiate 4 --memory 1g --disk 7:size=50g --nic vDS\_LabNetwork:IP=10.26.48.79 --name TESTHOST --cpu 1 --context ‘DATACENTER=DATACENTER1,[DOMAIN=domain1.net](http://DOMAIN=domain1.net),INSTALL\_APP=NO’

No matter how I try to format the syntax around --context it doesn’t appear the variables are being inserted into the instantiation process: Continually receive the message ''There are some parameters that require user input. Use the string \<\> to launch an editor (e.g. for multi-line inputs)"

[http://docs.opennebula.org/5.8/operation/vm\_management/vm\_instances.html](http://docs.opennebula.org/5.8/operation/vm_management/vm_instances.html)

and have to select all my options and the instance instantiates fine. Is there a way around this?  
I see references to having to do an additional append from a file to the template, but can’t this be done in one step?

Thank you,  
Christina

If you want to use user input vars, you can pass them from stdin with command like:

> printf “DATACENTER1\ndomain1.net\nNO” | onetemplate instantiate 4 --memory 1g --disk 7:size=50g --nic vDS\_LabNetwork:IP=10.26.48.79 --name TESTHOST --cpu 1

But you can also drop the user input vars and only pass the values to the context as you did with the --context attr.

Jimmy,

Thank you, this was exactly what I needed for now!  
After I read this, it made perfect sense.
