Creating a new Container App resource cannot select a subnet of the Virtual Network

Question

hi,

I am learning by doing the following applied skill: https://learn.microsoft.com/en-us/training/modules/deploy-manage-container-app-using-azure-container-apps/4-exercise-create-configure-container-app-azure-container-apps

I am stuck at step 7 of "Create a container app that uses an ACR image" section:

On the Create Container Apps Environment page, select the Networking tab, and then specify the following:

• Use your own virtual network: Select Yes.
• Virtual network: Select VNET1.
• Infrastructure subnet: ACASubnet.

the problem is that I cannot see any subnet in the list, even if I update the address range to 10.0.2.0/23 as suggested in the note.

anyone could help me out?

thanks!

Answer 1

It seems the Portal Interface might be bugged.

Go into the Virtual Network and Delete the ACASubnet

Then open a CloudShell and run:

az network vnet subnet create --resource-group RG1  --vnet-name VNET1  --name ACASubnet  --address-prefix '10.0.4.0/23'

Once the subnet has been created using the CLI

You should be able to select the Subnet in the VNET:
