工具镜像使用自定义镜像，报连接镜像仓库错误

使用kubectl debug pod_name -n ns-* --image harbor.*.com/base/bianque:v1.0.1
pulling image harbor.*.com/base/bianque:v1.0.1...
message: error execute remote, Internal error occurred: error attaching to container: Error response from daemon: pull access denied for harbor.*.com/base/bianque, repository does not exist or may require 'docker login': denied: requested access to the resource is denied
已经在agent-ds文件中添加imagessecret 尝试debug的服务器也登录了该HARBOR 手动直接拉该镜像也无问题

Start by reproducing the kubectl debug command with the custom Harbor image, then inspect how the agent-ds file's imagessecret setting is used during the remote image pull. Compare this behavior with a direct authenticated pull on the debug server; done means kubectl debug can pull and attach using the custom image.
