# Rebalancing or resizing autoscaled worker pools
{: #ca_update_worker_node_pool}

Before you can rebalance or resize your worker pool, you must remove the worker pool from the autoscaler configmap to disable autoscaling.


1. Edit `iks-ca-configmap` and disable the worker pool that you want to resize or rebalance by removing it from the `workerPoolsConfig.json` section.

    ```sh
    kubectl edit cm -n kube-system iks-ca-configmap
    ```
    {: pre}

    Example output

    ```yaml
    apiVersion: v1
    data:
      workerPoolsConfig.json: |
        [
         {"name": "","minSize": 1,"maxSize": 2,"enabled":false}
        ]
    kind: ConfigMap
    ```
    {: screen}

2. Save the `iks-ca-configmap`.

3. [Resize](https://cloud.ibm.com/docs/containers?topic=containers-kubernetes-service-cli&format=markdown#worker-pool-resize-cli) or [rebalance](https://cloud.ibm.com/docs/containers?topic=containers-kubernetes-service-cli&format=markdown#worker-pool-rebalance-cli) your worker pool.

4. **Optional** [Update your VPC worker nodes](https://cloud.ibm.com/docs/containers?topic=containers-update&format=markdown#vpc_worker_node).

5. Add the worker pool to the `iks-ca-configmap`.
    ```sh
    kubectl edit cm -n kube-system iks-ca-configmap
    ```
    {: pre}

    Example
    ```yaml
    apiVersion: v1
    data:
      workerPoolsConfig.json: |
        [
         {"name": "<worker_pool>","minSize": 1,"maxSize": 2,"enabled":false}
        ]
    kind: ConfigMap
    ```
    {: screen}
