# Run Windows Docker images

This topic describes how to run Windows-based Docker images in your Kubernetes Service cluster.

Note: All section are applicable for EKS, AKS, and on-premises Kubernetes.

To run Windows Docker images in your cluster:

1. Open the kubernetes.config file located in the <Server_installdir>\dat folder, and uncomment the tolerations section.

   Note:

   - Do not set the toleration value manually; it is configured automatically based on the image type.

   - The toleration key used is `node.kubernetes.io`.

2. Verify that your Windows node pools have the taint `node.kubernetes.io` applied. Toleration is only required if this taint is present.

3. (Optional) When provisioning elastic load generators, you can customize the timeout settings.

   1. Navigate to <Server_installdir>\dat\ and open the pcs.config file.

   2. Enter a new timeout value in `DockerProvisionTimeoutInSeconds`. We recommend using a higher timeout value when working with Windows OneLG images, as Windows-based images typically take longer to pull and initialize.

4. Create a custom Windows image for AKS nodes.

   Note: AKS Windows node compatibility Windows Server 2019 is no longer supported in AKS Windows node pools.

   - If you are running an AKS cluster with Windows node pools using Windows Server 2019, make sure that your Kubernetes version is 1.32 or earlier to remain in a supported state.

   - To continue using Windows nodes in AKS, you must migrate workloads to a custom image based on Windows Server 2022, because official images for Windows Server 2022 are not currently published.

   We recommend creating a custom OneLG Windows image that includes a valid `ENTRYPOINT` in the Dockerfile. This ensures that the container can run successfully within AKS Windows node.

   Example Dockerfile ENTRYPOINT:

   Copy code

       ENTRYPOINT ["C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell.exe", "-Command"]

   This configuration sets PowerShell as the entry point for your container, which is commonly required for Windows-based workloads in AKS.
