Hey @sabbour
It seems that there is an issue when using the CLI. Automatic mode should be using the standard tier and not free, but if you try and deploy in West Europe you get an error message saying free tier is unavailable. I would say this is a bug as we are not using the free tier.
Please see the error message in the image below.
@pixelrobots can you confirm which aks-extension version you're using in the CLI?
I am using 4.0.0b4.
I have also noticed it is not available via the portal yet even the preview one. I assume that will come at one point this week.
it also looks like the Prometheus recording rules are not enabled by default too.
And it also seems to have an issue with the monitor settings.

Yes, the new portal experience (create/manage) is lighting up shortly. It is behind a flag now at https://aka.ms/aks/flight/automatic.
@PixelRobots we're looking into the other issue now.
It will be better to mention the following command in the document to get the VM sizes available in all availability zones. I only tried this after 10 mins failure of creating AKS:
az vm list-skus --location southeastasia --output table
You can feel my pain:
az aks create -n testAKS -g eastusrG --sku automatic --node-vm-size Standard_D8ds_v5 --location eastus2 --no-ssh-key
Argument '--sku' is in preview and under development. Reference and support levels: https://aka.ms/CLI_refstatus
The behavior of this command has been altered by the following extension: aks-preview
(BadRequest) The VM size of Standard_D8ds_v5 is only allowed in zones [2 1] in your subscription in location 'eastus2'.
Code: BadRequest
Message: The VM size of Standard_D8ds_v5 is only allowed in zones [2 1] in your subscription in location 'eastus2'.
az aks create -n testAKS -g eastusrG --sku automatic --no-ssh-key
Argument '--sku' is in preview and under development. Reference and support levels: https://aka.ms/CLI_refstatus
The behavior of this command has been altered by the following extension: aks-preview

Code: BadRequest

az aks create -n testAKS -g eastusrG --sku automatic --node-vm-size Standard_B16als_v2 --no-ssh-key
Argument '--sku' is in preview and under development. Reference and support levels: https://aka.ms/CLI_refstatus
The behavior of this command has been altered by the following extension: aks-preview
(VMSizeDoesNotSupportEphemeralOS) The Virtual Machine size Standard_B16als_v2 does not support Ephemeral OS disk.
Code: VMSizeDoesNotSupportEphemeralOS
Message: The Virtual Machine size Standard_B16als_v2 does not support Ephemeral OS disk.
And another suggestion: also can specify a default value for --node-osdisk-size
while --sku automatic
enabled on az-cli
level, or otherwise:
joey [ ~ ]$ az aks create -n testAKS -g eastusrG --sku automatic --node-vm-size Standard_DC2s_v2 --location eastus --no-ssh-key
Argument '--sku' is in preview and under development. Reference and support levels: https://aka.ms/CLI_refstatus
The behavior of this command has been altered by the following extension: aks-preview
(VMCannotFitEphemeralOSDisk) The virtual machine size Standard_DC2s_v2 has a cache size of 46170898432 bytes and temporary disk size of 107374182400 bytes, but the OS disk requires 137438953472 bytes. Use a VM size with larger cache, larger temp disk, or disable ephemeral OS.
Code: VMCannotFitEphemeralOSDisk

It does can be fixed by specifying --node-osdisk-size
:
joey [ ~ ]$ az aks create -n testAKS -g eastusrG --sku automatic --node-vm-size Standard_DC2s_v2 --node-osdisk-type Ephemeral --node-osdisk-size 48 --location eastus --no-ssh-key

@JoeyC-Dev thanks for the feedback, we'll look into this and get the docs updated. This is mostly a limitation during preview.
Hey @sabbour

Please see the error message in the image below.
@PixelRobots my guess is that it's setting the tier to free
by default like the API does if not specified - but I've had those capacity errors in West Europe for days now, even on the standard
tier
I've had to create my clusters in UK South for the moment

So automatic should default to standard. Which it does. But the cli should not return that error in my opinion.
It's a bug, we're getting it fixed.
Today, when I try to create automatic AKS via Azure portal, I find out this:
This subscription does not have the flags: AKS-PrometheusAddonPreview registered. Preview features must be registered in order to create a cluster. To continue, register the required flags to the subscription.
But it is not mentioned in the section Register the feature flags, and I can create the automatic AKS via Azure CLI:
Not sure if the feature really needs to be registered, or it is a bug in Azure portal.
Unable to stop the AKS automatic cluster after my use.
Unable to stop the AKS automatic cluster after my use.
This is due to the node auto provisioning part of automatic. https://learn.microsoft.com/en-us/azure/aks/node-autoprovision?tabs=azure-cli#unsupported-features
@sabbour will this become a feature of nap and in turn automatic clusters.
agree, but it should have the feature, cx can stop and start the cluster.
Automatic clusters don't support start/stop.
Do you know when we can expect this to be resolved when using Bicep/Terraform?
Monitoring is wired up only when using the CLI and portal
And the earlier issues that were mentioned?
For something that's in public preview, this is proving quite hard to do PoCs on at this point
Just did a portal adventure to test some bits.
When creating going via the portal creating the log analytics workspace it puts it in a default resource group rather than the one with all other resources. Can we fix that please, so it is deployed in the same resource group as the cluster and other items.
I also noticed when I delete the cluster some resources are not cleaned up. This is not very automatic... can we have it, so they are cleaned up as long as the cluster is in automatic mode?
I have some questions/suggestions regarding the bring your own virtual network support:
Thank you!
@Jostepop
Will this feature allow us to control egress traffic? i.e. set egress type to user defined routing?
Yes.
Can we deploy AKS auto with only a load balancer (not ingress controller) and use a 3rd party reverse proxy like BigIP as ingress controller?
We will look into allowing disabling the ingress controller.
Does "Bring your own virtual network" means that we can provide a pre-deployed VNET with VNET peerings and route tables for the AKS auto deployment?
Yes.
AKS Automatic mode is a new capability within Azure Kubernetes Service (AKS) that lets you create optimized, ready-for-production clusters with reduced operational overhead. This means you can focus on building and running your applications, while AKS takes care of the rest.
AKS Automatic mode is currently in preview. You can get started today by following the quickstart guide on Microsoft Learn to create an AKS Automatic cluster and deploy an application.
Learn more about AKS Automatic: https://aka.ms/aks/automatic
We would love to hear your feedback and suggestions on how to make AKS Automatic mode even better and continue to boost your focus on your workloads.
Below are some of the current limitations, which will be broken into their own roadmap items.
