@jchauncey how is the vnet creation handled for the ginkgo e2e runner?

[jchauncey]

its hard coded right now (see line 107 in cli_provisioner.go)

[jchauncey]

	vnetName := fmt.Sprintf("%sCustomVnet", cli.Config.Name)
	subnetName := fmt.Sprintf("%sCustomSubnet", cli.Config.Name)
	if cli.CreateVNET {
		err = cli.Account.CreateVnet(vnetName, "10.239.0.0/16", subnetName, "10.239.0.0/16")
		if err != nil {
			return fmt.Errorf("Error trying to create vnet:%s", err)
		}
		subnetID = fmt.Sprintf("/subscriptions/%s/resourceGroups/%s/providers/Microsoft.Network/virtualNetworks/%s/subnets/%s", cli.Account.SubscriptionID, cli.Account.ResourceGroup.Name, vnetName, subnetName)
	}

@jchauncey thanks. @zqingqing1 It looks like the VNET is being created with the 10.239.0.0/16 address space, and a single subnet that comprises the whole 10.239.0.0/16 space. This means we need to change the clusterSubnet value as well to be 10.239.0.0/16. Thanks!

I searched for all files, and found that 10.230.0.0/16 occurs at 2 files. One is at this file, another is at examples\kubernetes-config\kubernetes-clustersubnet.json. How clustersubnet in the latter file being used? @jchauncey @jackfrancis

lgtm pending E2E
