Fix the problem of container restart failure

1. When restart docker, the kind container restart failed. Docker logs: ``` INFO: Detected IPv4 address: 172.18.0.2 INFO: Detected old IPv4 address: 172.18.0.2 ERROR: Have an old IPv4 address but no current IPv4 address (!) ``` 2. After modifying the file and replacing it, the container starts normally: ``` docker cp entrypoint cluster-control-plane:/usr/local/bin/entrypoint docker start cluster-control-plane ```
