FAQ
Symptom 1: Pods cannot be scheduled to CCI. After the kubectl get node command is executed on the CCE cluster console, the output showed that the virtual-kubelet node is in the SchedulingDisabled state.
Cause: CCI resources are sold out. As a result, scheduling to CCI failed, and the bursting node will be locked (in the SchedulingDisabled state) for half an hour, during which the pods cannot be scheduled to CCI.
Solution: Use kubectl to check the status of the bursting node on the CCE cluster console. If the bursting node is locked, you can manually unlock it.
Symptom 2: Elastic scheduling to CCI is unavailable.
Cause: The subnet where the CCE cluster resides overlaps with 10.247.0.0/16, which is the CIDR block reserved for the Service in the CCI namespace.
Solution: Reset a subnet for the CCE cluster.
Symptom 3: After the bursting add-on is rolled back from 1.5.18 or later to a version earlier than 1.5.18, pods cannot be accessed through the Service.
Cause: Once the add-on is upgraded to 1.5.18 or later, the sidecar in each pod that is newly scaled to CCI is incompatible with the add-on of a version earlier than 1.5.18. So, after the add-on is rolled back, the access to the pods is abnormal. If the add-on version is earlier than 1.5.18, pods scaled to CCI are not affected.
Solutions:
- Solution 1: Upgrade the add-on to 1.5.18 or later again.
- Solution 2: Delete the pods that failed to be accessed through the Service and create pods. The new pods scaled to CCI can be accessed normally.
