Reliability Hardening for Cluster Networks and Storage Functions

Released: Apr 26, 2024

If there is a regional fault in the IAM service, it is likely that an authentication exception will occur. This can impact certain functions within a cluster, such as workload storage volume mounting and load balancing interconnection. The newest version of the CCE clusters has been improved and strengthened to handle this type of fault. To maintain stable service performance, we recommend upgrading your account's clusters to the target version as soon as possible.

Trigger Condition

All the following conditions are met:

  1. Cluster version ranges:
    • EOS versions: 1.19 and earlier versions
    • Version 1.21 (end of maintenance on April 30, 2024, 00:00 GMT+08:00): v1.21.1-r0 to v1.21.11-r40
    • Version 1.23: v1.23.1-r0 to v1.23.10-r20
    • Version 1.25: v1.25.1-r0 to v1.25.5-r20
    • Version 1.27: v1.27.1-r0 to v1.27.2-r20
  2. During a regional fault in the IAM service, the temporary IAM access key in a cluster expires.
  3. When creating or updating a workload in a cluster, pod startup is necessary, and functions like storage volume mounting and load balancing are required.

Solution

Keep an eye on the patch version release records and upgrade your clusters to the target version in a timely manner. For clusters that have reached EOS, upgrade them to versions under maintenance.

Target cluster versions:

  • Version 1.21 (end of maintenance on April 30, 2024, 00:00 GMT+08:00): v1.21.12-r0 or later
  • Version 1.23: v1.23.11-r0 or later
  • Version 1.25: v1.25.6-r0 or later
  • Version 1.27: v1.27.3-r0 or later
  • Version 1.28: v1.28.1.0 or later
