[BUG] KubeBlocks 0.8.4 Crashes After Updating SVC to Existing Clusters.

[dingshun-cmss]

Describe the Bug

For an existing KubeBlocks Add-On, we added a sidecar container to one of the components in the ClusterDefinition. After upgrading the add-on using Helm, the KubeBlocks Pod started crashing continuously.

Steps to Reproduce

To reproduce the behavior in a KubeBlocks 0.8.4 environment:

1. Install the initial version of the KubeBlocks add-on.
2. Create a cluster using this add-on.
3. Modify the KubeBlocks add-on by adding a sidecar container with specific configurations and startup scripts.
4. Use helm upgrade to upgrade the modified KubeBlocks add-on.
5. Check the status of the KubeBlocks operator Pods. The operator Pod will crash continuously.

Expected Behavior

The KubeBlocks operator should continue to operate normally after the upgrade.

Screenshots
