UpgradeChannel
Fields
| Name | Value | Description |
|---|---|---|
| Rapid | 0 | Automatically upgrade the cluster to the latest supported patch release on the latest supported minor version. In cases where the cluster is at a version of Kubernetes that is at an N-2 minor version where N is the latest supported minor version, the cluster first upgrades to the latest supported patch version on N-1 minor version. For example, if a cluster is running version 1.17.7 and versions 1.17.9, 1.18.4, 1.18.6, and 1.19.1 are available, your cluster first is upgraded to 1.18.6, then is upgraded to 1.19.1. |
| Stable | 1 | Automatically upgrade the cluster to the latest supported patch release on minor version N-1, where N is the latest supported minor version. For example, if a cluster is running version 1.17.7 and versions 1.17.9, 1.18.4, 1.18.6, and 1.19.1 are available, your cluster is upgraded to 1.18.6. |
| Patch | 2 | Automatically upgrade the cluster to the latest supported patch version when it becomes available while keeping the minor version the same. For example, if a cluster is running version 1.17.7 and versions 1.17.9, 1.18.4, 1.18.6, and 1.19.1 are available, your cluster is upgraded to 1.17.9. |
| NodeImage | 3 | Automatically upgrade the node image to the latest version available. Consider using nodeOSUpgradeChannel instead as that allows you to configure node OS patching separate from Kubernetes version patching. |
| None | 4 | Disables auto-upgrades and keeps the cluster at its current version of Kubernetes. |
