At first, i searched if there is a commandlet for creating an edge. Sadly the only edge commandlet I got was Get-EdgeGateway. So I had to find another way.
Following the UI, an edge is created inside an OrgVDC. Therefore I searched for a method in the OrgVDC object. Easily I found it as always beneath the ExtensionData Sub-Object. A method called CreateEdgeGateway.
Get-Member -InputObject $orgvdc.ExtensionData -Name CreateEdgeGateway
TypeName: VMware.VimAutomation.Cloud.Views.AdminVdc

CreateEdgeGateway Method VMware.VimAutomation.Cloud.Views.Gateway CreateEdgeGateway(VMware.VimAutomation.Cloud.Views.Gateway gateway)
As i do such things in the last blog posts, I created a new VMware.VimAutomation.Cloud.Views.Gateway object and tried to pass it to the CreateEdgeGateway method. Of course I failed first because the Gateway object has no filled properties.
A look in the API documentation (https://code.vmware.com/apis/912/vmware-cloud-director/doc/doc/types/GatewayType.html ) shows, that there are some required properties. The name of course and the Configuration property which consists of a VMware.VimAutomation.Cloud.Views.GatewayConfiguration object.
Again I created a new object of type VMware.VimAutomation.Cloud.Views.GatewayConfiguration. But this time I first looked in the documentation (https://code.vmware.com/apis/912/vmware-cloud-director/doc/doc//types/GatewayConfigurationType.html) which properties are required. I saw that I had to fill GatewayBackingConfig and GatewayInterfaces.GatewayBackingConfig is a simple string which defines the size of the edge. I choosed compact, because I wanted the smallest type of edge here.GatewayInterfaces is of type VMware.VimAutomation.Cloud.Views.GatewayInterfaces
which is an array for objects of type VMware.VimAutomation.Cloud.Views.GatewayInterface. So, first I needed to create a GatewayInterfaces object and had to add a GatewayInterface object.
At last, this GatewayInterface object needs an ip configuration. (An edge without an external ip doesn’t really make sense to me.) Therefore I had to fill the SubnetParticipation property for which I also had to create an object of type VMware.VimAutomation.Cloud.Views.SubnetParticipation. (https://code.vmware.com/apis/912/vmware-cloud-director/doc/doc/types/SubnetParticipationType.html)
In Summary i had to create the following objects in order to create a functional edge gateway:
Gateway -> GatewayConfiguration -> GatewayInterfaces -> GatewayInterface -> SubnetParticipation
After all this chained objects are filled with properties I could create the edge with the CreateEdgeGateway method of the OrgVDC object.
