[plugins."io.containerd.grpc.v1.cri".registry] [plugins."io.containerd.grpc.v1.cri".registry.configs] [plugins."io.containerd.grpc.v1.cri".registry.configs."192.168.62.150".tls] insecure_skip_verify = true [plugins."io.containerd.grpc.v1.cri".registry.mirrors] [plugins."io.containerd.grpc.v1.cri".registry.mirrors."docker.io"] endpoint = ["https://bqr1dr1n.mirror.aliyuncs.com"] [plugins."io.containerd.grpc.v1.cri".registry.mirrors."192.168.62.150"] endpoint = ["http://192.168.62.150"] ```
