Announcement on upgrading the CCM component-Container Service for Kubernetes(ACK)-阿里云帮助中心

Upgrade the Cloud Controller Manager (CCM) component in your Container Service for Kubernetes (ACK) cluster to the latest version to improve the stability of LoadBalancer Services.

Background information

CCM component versions earlier than v1.9.3.380 have the following issues, which may affect the stability of LoadBalancer Services in your ACK cluster:
- The default server group fails to be updated.
- A vServer group fails to be updated because another vServer group with the same name exists.
For more information, see Cloud Controller Manager.
If the CCM component upgrade precheck fails, see Troubleshoot CCM component upgrade precheck failures for solutions.

Upgrade the CCM component

Log on to the ACK console. In the left navigation pane, click Clusters.
On the Cluster List page, click the name of the destination cluster or click Details in the Actions column.
In the left navigation pane of the cluster management page, choose O&M Management > Component Management.
On the Add-ons page, click the Core Components tab. Find the Cloud Controller Manager card in the add-on list and click Upgrade.

Note
If no upgrade button is displayed on the Cloud Controller Manager card, the CCM component is already up to date and does not need to be upgraded.
In the Note dialog box, click OK.
