Closed JashBook closed 4 months ago

JashBook commented 4 months ago

Describe the bug

kbcli version
Kubernetes: v1.28.9-gke.1289000
KubeBlocks: 0.9.0-beta.44
kbcli: 0.9.0-beta.2

Last_SQL_Error: Error 'Can't create database 'benchtest'; database exists' on query. Default database: 'benchtest'. Query: 'create database benchtest'

To Reproduce Steps to reproduce the behavior:

  1. create cluster 
    kbcli cluster create  asmysql-uedaby --termination-policy=Halt --cluster-definition=mysql --enable-all-logs=false --cluster-version=mysql-5.7.44 --set cpu=100m,memory=0.5Gi,replicas=2,storage=10Gi  
    
kbcli cluster list-instances asmysql-uedaby --namespace default
