步骤一：源集群数据采集

1. 通过kubectl连接源集群。具体方法可参考使用kubectl连接集群。
2. 使用默认参数配置，采集集群中所有命名空间的数据。执行方法：./kspider-linux-amd64
   执行后的输出详细信息如下：

   在kspider执行完毕后，当前目录下将生成两个文件：

   • cluster-*.json：此文件包含了源集群及应用的采集数据，这些数据可用于分析和规划迁移过程。
   • preferred-*.json：此文件包含了推荐的目标集群信息。基于源集群的规模和节点规格进行初步评估，文件将提供关于目标集群版本和规模的建议。

3. 查看源集群及应用的采集数据。

   您可以用文本编辑器或JSON查看器打开“cluster-*.json”文件以查看数据。在实际操作中，您需要将文件名中的“*”替换为实际的时间戳或序列号，以找到并打开正确的文件。

   “cluster-*.json”文件说明如下：
