Description

Azure Kubernetes Service will no longer support the WebAssembly System Interface (WASI) nodepools (preview). Starting on May 5, 2025 you will no longer be able to create new WASI nodepools. If you'd like to run WebAssembly (WASM) workloads, you can deploy SpinKube to Azure Kubernetes Service (AKS) from Azure Marketplace. 

 

Required Action
Create new node pools following the AKS-supported alternative method using SpinKube and migrate existing workloads.
