无法提取图片：对gin-web拒绝访问权限，存储库不存在或者可能需要“docker login”

我有一个Docker镜像gin-web，我在本地也可以推送到Docker Hub。当我在运行我的Kubernetes文件夹时，即Kubernetes/我的错误k8s-deployment.yml

Kubernetes由 控制台组成k8s-deployment.yml和k8s-service.yml服务。（使用minikube dashboard）。

我已经将已配置的Pod引用从私有注册表中提取图像并添加imagePullSecrets到k8-deployment.yml

我在Kubernetes控制台中的Deployments下遇到此错误：

Failed to pull image "gin-web:1.0.1": rpc error: code = Unknown desc = Error response from daemon: pull access denied for gin-web, repository does not exist or may require 'docker login'
