Node Pool Runtime

Check Items

Check whether an alarm is generated when a cluster is upgraded to v1.27 or later. Do not use Docker in clusters of versions later than 1.27 because CCE is going to stop the support for Docker.

Solution

If you plan to create and use Docker node pools in a cluster later than v1.27, ignore this alarm. However, you are advised to switch to containerd as soon as possible for a better user experience and more powerful functions.
