Modify the connection whitelist for a tenant

If you want to update the list of IP addresses allowed to connect to a tenant, you can modify the connectWhiteList parameter in the tenant configuration file. When you modify this parameter, the value must include the CIDR block of ob-operator; otherwise, ob-operator cannot connect to the tenant.

1. Modify the value of connectWhiteList in the spec section in the tenant configuration file tenant.yaml.

   spec:
     ...
     connectWhiteList: '%'
   

2. Run the following command for the modification to take effect:

   kubectl apply -f tenant.yaml
   

3. Run the following command to view the custom resources of the tenant in the current Kubernetes cluster to check whether the modification is successful:

   kubectl get obtenants.oceanbase.oceanbase.com -n oceanbase -o yaml
   

   If the value of the corresponding parameter in the spec:connectWhiteList section in the custom resources of the tenant is changed to the new value, the modification is successful.

    spec:
     obcluster: obcluster
     connectWhiteList: '%'
     pools:
