CLB supports instance cloning. This feature allows you to easily copy the configuration of existing CLB instances, including instance attributes, listeners, security groups, and logs.
Note:
Restrictions
Instance attribute restrictions
Only pay-as-you-go instances can be cloned.
CLB instances without any billable items cannot be cloned.
Classic CLB instances and CLB with Anti-DDoS Pro cannot be cloned.
Classic network-based instances cannot be cloned.
IPv6 instances, IPv6 NAT64 instances, and instances binding IPv4 and IPv6 simultaneously cannot be cloned.
The following settings will not be cloned and require reconfiguration: Custom configuration, Redirection configurations, and Allow Traffic by Default in security groups.
Before cloning an instance, make sure all certificates used on the instance are valid. Cloning will fail if there are any expired certificates.
Listener restrictions
Instances with QUIC listeners or port range listeners cannot be cloned.
Private network CLB instances with TCP_SSL listeners cannot be cloned.
Instances with layer-7 listeners that have no forwarding rules cannot be cloned.
A CLB instance associated with over 50 listeners cannot be cloned.
Real server restrictions
Instances with the target group and SCF as the real server type cannot be cloned.
Cloning Instances in the Console
1. Log in to the CLB console and click Instance management in the left sidebar.
2. Select a region in the top-left corner of the Instance management page, find the instance to be cloned in the instance list, and choose More > Clone in the Operation column of the instance.
3. In the pop-up window, enter the name of the target instance and click OK.
