AKS Cluster Node Requirements?

I was going to create a small single node AKS cluster 2core 2gb, but cant seem to now do so, even though I have done so in the pass many times , mostly on another account.

Why is the min core count now set to 4? The cheapest VM size for that is a little over £100?? That is way way to much for a small site that gets no use?

Even when I have gone though these new (i have only seen them from today) profiles / presets, selecting the 'dev/test', it will still not let me set a lower VM size? Really a 4core over the top VM for a test system when I might only want a small VM?

Is this just me, or is this for everyone now?

As I just got a three year reservations on a mid range system to play around with devOps with - but if i had known this was a change that was coming, i would not have. I wanted to place all my work within Azure - if I cant do that, because i have to spend over double on a single node VM, this whole platform is just completely useless for my personal use.

    Hello @Glenn ,
    I just tested locally with DS2v2 (Default SKU which comes with at the time of AKS cluster creation), able to create successfully.
    Can you try out using azure cli ?

    az aks create -n test12 -g test12 --node-vm-size Standard_D2_v2

    Probably you are using Azure Portal and while selecting a VM size with 2 core VM - Select button is disabled ?

    Regards,

    Hello @Glenn ,
    It's working in the Azure Portal when you go to "Node Pools" page section and select the corresponding 2 core VM.
    Coming back to your follow-up question. That should be okay as far as you are able to create it using TF/Azure CLI. (Azure CLI is much easier)

    Hope that helps!
