 Change log for worker node fix pack 4.5.41_1547_openshift, released 02 August 2021
Update worker nodes to apply the latest security updates and patches to the operating system, and to update the Kubernetes version to match the version of the Kubernetes master. You can update the master Kubernetes version with the ibmcloud ks cluster master update[command](https://cloud.ibm.com/docs/cli?topic=cli-kubernetes-service-clics_cluster_update). Remember that your worker nodes can be only up to two versions behind the master version (n-2). The worker node IP address remains the same after the update operation.

To update a worker node in a VPC cluster, use the [ibmcloud ks worker replace command](https://cloud.ibm.com/docs/cli?topic=cli-kubernetes-service-clicli_worker_replace) instead.

Running ibmcloud ks worker update can cause downtime for your apps and services. During the update, all pods are rescheduled onto other worker nodes, the worker node is reimaged, and data is deleted if not stored outside the pod. To avoid downtime, [ensure that you have enough worker nodes to handle your workload while the selected worker nodes are updating](https://cloud.ibm.com/docs/containers?topic=containers-updateworker_node).

To update Satellite worker nodes, see [Updating hosts that are assigned as worker nodes to Satellite-enabled services](https://cloud.ibm.com/docs/satellite?topic=satellite-host-update-workers).

You might need to change your YAML files for deployments before you update. Review this [release note](https://cloud.ibm.com/docs/containers?topic=containers-cs_versions) for details.

ibmcloud ks worker update --cluster CLUSTER --worker WORKER_ID [-f] [-q]

Minimum required permissions
: Operator platform access role for the cluster in IBM Cloud Kubernetes Service

Command options:

-c, --cluster CLUSTER
: Required: The name or ID of the cluster where you list available worker nodes.

-w, --worker WORKER
Worker node patch updates can be applied by updating, reloading (in classic infrastructure), or replacing (in VPC infrastructure) the worker node.

To update Satellite worker nodes, see [Updating hosts that are assigned as worker nodes to Satellite-enabled services](https://cloud.ibm.com/docs/satellite?topic=satellite-host-update-workers).



* Patch: A worker node patch update includes security fixes. You can update the VPC worker node to the latest patch by using the ibmcloud oc worker replace command.
* Major.minor: A major.minor update moves up the Kubernetes version of the worker node to the same version as the master. This type of update often includes changes to the Kubernetes API or other behaviors that you must prepare your cluster for. Remember that your worker nodes can only be one version behind the master version (n-1). You can update the VPC worker node to the same patch by using the ibmcloud oc worker replace command with the --update option.



For more information, see [Update types](https://cloud.ibm.com/docs/containers?topic=containers-cs_versionsupdate_types).

What happens to my apps during an update?
: If you run apps as part of a deployment on worker nodes that you update, the apps are rescheduled onto other worker nodes in the cluster. These worker nodes might be in a different worker pool. To avoid downtime for your app, you must ensure that you have enough capacity in the cluster to carry the workload, such as by [resizing your worker pools](https://cloud.ibm.com/docs/openshift?topic=openshift-add_workersresize_pool).

What happens to my worker node during an update?
: Your VPC worker node is replaced by removing the old worker node and provisioning a new worker node that runs at the updated patch or major.minor version. The replacement worker node is created in the same zone, same worker pool, and with the same flavor as the deleted worker node.
