1.4. Updating a cluster by using the web console
If updates are available, you can update your cluster from the web console.
You can find information about available OpenShift Container Platform advisories and updates in the errata section of the Customer Portal.
Prerequisites
-
Have access to the web console as a user with
adminprivileges.
Procedure
- From the web console, click Administration > Cluster Settings and review the contents of the Overview tab.
For production clusters, ensure that the CHANNEL is set to the correct channel for your current minor version, such as
stable-4.5.重要For production clusters, you must subscribe to a stable-* or fast-* channel.
- If the UPDATE STATUS is not Updates Available, you cannot upgrade your cluster.
- The DESIRED VERSION indicates the cluster version that your cluster is running or is updating to.
-
Click Updates Available, select the highest available version and click Update. The UPDATE STATUS changes to
Updating, and you can review the progress of the Operator upgrades on the Cluster Operators tab. After the update completes and the Cluster Version Operator refreshes the available updates, check if more updates are available in your current channel.
- If updates are available, continue to perform updates in the current channel until you can no longer update.
- If no updates are available, change the CHANNEL to the stable-* or fast-* channel for the next minor version, and update to the version that you want in that channel.
You might need to perform several intermediate updates until you reach the version that you want.
