 Component Previous Current Description 

 Cluster health image v1.3.6 v1.3.7 Updated Go to version 1.17.10 and also updated the dependencies. Update registry base image version to 104 
 GPU device plug-in and installer 9485e14 382ada9 Updated Go to version 1.17.9 
 IBM Calico extension 954 980 Updated to use Go version 1.17.10. Updated minimal UBI to version 8.5. 
 IBM Cloud Controller Manager v1.22.8-7 v1.22.10-1 Updated to support the Kubernetes 1.22.10 release. 
 IBM Cloud File Storage for Classic plug-in and monitor 408 410 Updated universal base image (UBI) to version 8.6-751 to resolve CVEs.
During the update, your highly available master can continue processing requests, and your app workloads and worker nodes continue to run. After the master update is complete, you can [update your worker nodes](https://cloud.ibm.com/docs/containers?topic=containers-updateworker_node). If the update is unsuccessful, the master returns to a deployed state and continues running the previous version. IBM Support is notified and works to resolve the issue. You can check if the update failed in the Master Status field. 
 update_cancelled The master update is canceled because the cluster was not in a healthy state at the time of the update. Your master remains in this state until your cluster is healthy and you manually update the master. To update the master, use the ibmcloud oc cluster master update[command](https://cloud.ibm.com/docs/containers?topic=containers-kubernetes-service-clics_cluster_update). If you don't want to update the master to the default major.minor version during the update, include the --version option and specify the latest patch version that is available for the major.minor version that you want, such as 1.26. To list available versions, run ibmcloud oc versions. 
 update_failed The master update failed. IBM Support is notified and works to resolve the issue. You can continue to monitor the health of the master until the master reaches a normal state. If the master remains in this state for more than 1 day, [open an IBM Cloud support case](https://cloud.ibm.com/docs/containers?topic=containers-get-help). IBM Support might identify other issues in your cluster that you must fix before the master can be updated. 









 Disabling remote health reporting 

OpenShift Container Platform collects anonymized health reports about your cluster through a [telemetry component that is enabled by default](https://docs.openshift.com/container-platform/4.11/support/remote_health_monitoring/about-remote-health-monitoring.html) in your Red Hat OpenShift on IBM Cloud cluster.

These worker node fix packs can be at a higher version than the master because some build fix packs are specific to worker nodes. Other change logs are for master fix packs, and apply only to the cluster master. Master fix packs might not be automatically applied.

 Version 1.19 change log 

Review the version 1.19 change log.

Kubernetes version 1.19 is deprecated, with a tentative unsupported date of 14 Mar 2022. Update your cluster to at least [version 1.20](https://cloud.ibm.com/docs/containers?topic=containers-cs_versions_120) as soon as possible.



 Change log for worker node fix pack 1.19.16_1579, released 14 March 2022 



Changes since version 1.19.16_1579

 Component Previous Current Description 

 Ubuntu 18.04 packages 4.15.0-169-generic 4.15.0-171-generic Kernel and package updates for [CVE-2016-10228](https://nvd.nist.gov/vuln/detail/CVE-2016-10228), [CVE-2019-25013](https://nvd.nist.gov/vuln/detail/CVE-2019-25013), [CVE-2020-27618](https://nvd.nist.gov/vuln/detail/CVE-2020-27618), [CVE-2020-29562](https://nvd.nist.gov/vuln/detail/CVE-2020-29562), [CVE-2020-6096](https://nvd.nist.gov/vuln/detail/CVE-2020-6096), [CVE-2021-3326](
If Upgrade available does not appear on the tile when it should be there, make sure your console is using the latest version using the [Refresh cluster](https://cloud.ibm.com/docs/blockchain?topic=blockchain-ibp-console-manage-consoleibp-console-refresh) feature.

You can then update the node:



1. Click on the tile representing the node.
2. The upgrade panel can be accessed either by clicking the Info and usage tab, next to the Upgrade available notice, or the Fabric version box. Clicking either one opens the Upgrade Fabric version side panel.
3. On the Upgrade Fabric version side panel, review the version of your node and the version you are upgrading to. If this is right, click Next.
4. On the next panel, confirm the information and enter the name of the node being upgraded.



The node will be unavailable during the upgrade. The status was turn grey and will read Status unknown or Unavailable. When the upgrade has completed, the status will turn green and be Ready. If the upgrade fails and the node lapses into an unrecoverable state, follow the instructions for [Restoring nodes](https://cloud.ibm.com/docs/blockchain?topic=blockchain-backup-restorebackup-restore-restore) from a snapshot.

It is a best practice to only upgrade one node of each type at a time. In other words, if you need to upgrade both peers and ordering nodes, you can start a single peer upgrade and a single ordering node upgrade at the same time. However, do not attempt to upgrade multiple peers or multiple ordering nodes at the same time, as this threatens the availability of your components.

It is not possible to upgrade an ordering node if any node in your ordering service is down for any reason. Coordinate with all of the administrators of your ordering service before attempting to upgrade.





 Step three: Update SDKs and smart contracts 

It is a best practice to upgrade your SDK to the latest version as part of a general upgrade of your network.

For more information, see [Updating cluster add-ons](https://cloud.ibm.com/docs/containers?topic=containers-updateaddons).

Periodically, Kubernetes releases [major, minor, or patch updates](https://cloud.ibm.com/docs/containers?topic=containers-cs_versionsupdate_types). These updates can affect the Kubernetes API server version or other components in your Kubernetes master. IBM automatically updates the patch version, but you must update the master major and minor versions. For more information, see [Updating the master](https://cloud.ibm.com/docs/containers?topic=containers-updatemaster).

Worker nodes in standard clusters are provisioned in to your IBM Cloud infrastructure account. The worker nodes are dedicated to your account and you are responsible to request timely updates to the worker nodes to ensure that the worker node OS and IBM Cloud Kubernetes Service components apply the latest security updates and patches. Security updates and patches are made available by IBM Site Reliability Engineers (SREs) who continuously monitor the Linux image that is installed on your worker nodes to detect vulnerabilities and security compliance issues. For more information, see [Updating worker nodes](https://cloud.ibm.com/docs/containers?topic=containers-updateworker_node).
* Are the master and worker nodes highly available?

The IBM Cloud Kubernetes Service architecture and infrastructure is designed to ensure reliability, low processing latency, and a maximum uptime of the service. By default, every cluster in IBM Cloud Kubernetes Service is set up with multiple Kubernetes master instances to ensure availability and accessibility of your cluster resources, even if one or more instances of your Kubernetes master are unavailable.

You can make your cluster even more highly available and protect your app from a downtime by spreading your workloads across multiple worker nodes in multiple zones of a region. This setup is called a [multizone cluster](https://cloud.ibm.com/docs/containers?topic=containers-ha_clustersmz-clusters) and ensures that your app is accessible, even if a worker node or an entire zone is not available.
