Kubectl端口转发MinIO控制台遇broken pipe及timeout问题求助

问题现象 #

• 端口转发访问MinIO控制台时，连接仅短暂可用，终端反复输出连接处理日志：

  Handling connection for 9000
  Handling connection for 42935
  Handling connection for 42935
  ...
  

• 片刻后出现管道断裂错误：

  E0128 18:22:01.801739   40952 portforward.go:378] error copying from remote stream to local connection: readfrom tcp6 [::1]:42935->[::1]:50796: write tcp6 [::1]:42935->[::1]:50796: write: broken pipe
  

• 最终持续输出超时及管道断裂报错：

  E0128 18:22:31.738313   40952 portforward.go:346] error creating error stream for port 42935 -> 42935: Timeout occurred
  Handling connection for 42935
  E0128 18:22:32.120930   40952 portforward.go:346] error creating error stream for port 42935 -> 42935: write tcp 192.168.0.16:50776->34.133.9.102:443: write: broken pipe
  ...
  

• 控制台页面可显示但持续加载，登录时页面不断刷新直至崩溃或超时。

已执行的调整操作 #

• 将MinIO Service的类型从ClusterIP修改为LoadBalancer
• 在MinIO容器启动参数中添加--console-address ":42935"，并在Service中暴露该端口
