k3sup安装较旧的kubectl版本v1.24.3

Question

我使用crunchydata/postgres-操作符进行基于k3s的设置，但是由于kubectl上的最新版本，我已经开始收到错误，如下所示：

解决这个问题的正确方法是什么？我尝试了提供的头盔图表：https://github.com/CrunchyData/postgres-operator-examples，但仍然没有成功。

谢谢

我通过在Kubernetes版本上设置旧版本来解决这个问题。我正在使用k3sup install安装集群，所以我只是在命令中添加了版本，比如k3sup install --k3s-channel v1.24
