How to compose VMs with vlans using MaaS CLI?

Hi,

I’m fedup composing machines “by hand” using the MaaS UI because it is way too slow when you want to compose 10 VMs with exactly the same specs.
I know Juju can dynamically create machines based on constraints but doing this way, you can’t have finer indepth regarding network or machines specs.

So I tried with the MaaS CLI and ended up with something like this :

maas <PROFILE> vm-host compose <VM_HOST_ID> \
    cores=4 memory=16384 \
    storage=mylabel:50(default) \
    interfaces=ens4:space=SPACE-PXE \
    hostname=<VM_NAME>

This works well when creating a 4 vCPUs/16GB RAM/50GB disk and 1 interface plugged on the provisionning network.
But now, I’d like to add a few vlans on this interface.
I can do it very easily through the MaaS UI but I didn’t find a way to do it the CLI way.

Can somebody help me on this ?

Best regards.

interfaces is a list, so you can specify many of them in that one compose command

@sparkiegeek Thanks for the information but do you have an example ?
Because I tried many things without results and I don’t find a valuable answer in the documentation.

Let’s say that you have an interface called “ens4” on top of which you want to declare 2 vlans (vlan1, vlan2) with their corresponding subnet and autoassign an IP for vlan1 and defining a static IP for vlan2.
How would you do that ?
