Hello,

az aks update --resource-group myResourceGroup --name myAKSCluster --load-balancer-outbound-ports 4000

Microsoft documentation doesn't state elsewhere that this command could update node image version to the latest available, which might cause potential downtime. Please, describe this behavior in a more clear way.

Hi there!
I have a tiny clarification on an issue description:

Related command
az aks update, not az aks create

Hi @dbradish-microsoft, @yonzhan!

I just wonder whether someone checked it after this issue was created.
I see that it has no assignee.

Hello.

Does anyone care about this? As mentioned in the description, this behavior can cause downtime when executed.
So if it's an expected behavior it SHOULD be documented and if it's a bug, that should be fixed.

@mykolaichuk, The az aks update command is used in 131 conceptual GitHub files spread across 13 GitHub repos. I feel this information might be helpful in the reference help as repeating the same FYI message 131 times doesn't sound like a good solution to me. Based on the Azure CLI Service Contact List, I've assigned this issue to @andyliuliming. I've also added an H3 ### Request to engineering in the description.
