我在IBM VPC Gen2基础架构上创建了一个k8s集群。当我部署我的应用程序时，它无法从DockerHub中提取图像。我得到了以下错误。端口443在VPC Infrastucture/All Security groups/Rules下启用。我找不到任何有帮助的文件。所有文档都在讨论设置IBM注册表，然后将docker映像推送到该注册表。
错误
Failed to pull image "metacontrollerio/metacontroller:v1.4.0": rpc error: code = Unknown desc = failed to pull and unpack image "docker.io/metacontrollerio/metacontroller:v1.4.0": failed to resolve reference "docker.io/metacontrollerio/metacontroller:v1.4.0": failed to do request: Head "https://registry-1.docker.io/v2/metacontrollerio/metacontroller/manifests/v1.4.0": dial tcp 107.23.X.X:443: i/o timeout
部署模式
在kustomize的帮助下使用CLI部署
