Upgrade warm-up/upgrade

When a new version of the product is released, an icon will appear next to the product name on the product list page or detail page. When you move the cursor over the icon, you can view the upgrade prompt information.

The platform supports upgrade warm-up, which can automatically pull the corresponding upgrade package to prepare for automatic upgrade before the upgrade. After the preparation is completed, the basic platform and the deployed sub-products (Container Platform, DevOps, Service Mesh) can be upgraded to the latest version through the upgrade function. During the product upgrade process, Kubernetes will also be automatically upgraded to the latest version compatible with the product.

Cautions

• Only adjacent version upgrades are supported, and cross-version upgrades are not supported.

• When upgrading, the basic platform will be upgraded first. If the basic platform upgrade fails, the product upgrade will fail. After the basic platform upgrade is successful, the deployed sub-products will be upgraded in parallel.

• When one or more upgrades fail in the basic platform or sub-products, the product status is Upgrade Failed, and the entire product needs to be upgraded again.

Upgrade warm-up

Before upgrading the platform version, the upgrade warm-up function can be used to pull the images required for the upgrade to the local image repository.

Prerequisites

• Online O&M is enabled.

• The global cluster and business cluster versions are consistent, refer to How to upgrade to a unified version? .

• If there is an upgradable version, an icon will appear next to the product name on the product list page or the product details page.

• When selecting a version on the upgrade preheating operation page, refer to the platform prompt to reserve sufficient storage space to ensure that the required image is downloaded.

• If you are using an external image repository that does not support upgrade preheating, manually download the new version from the external image repository and then use the Upgrade function to upgrade the platform version.
