registry.cn-hangzhou 与 k8s.gcr.io 同步事宜

[oldunclez]

安装最新版的k8s需要以下

root@test-k-1:~# kubeadm config images list                                                                       
k8s.gcr.io/kube-apiserver:v1.22.1
k8s.gcr.io/kube-controller-manager:v1.22.1
k8s.gcr.io/kube-scheduler:v1.22.1
k8s.gcr.io/kube-proxy:v1.22.1
k8s.gcr.io/pause:3.5
k8s.gcr.io/etcd:3.5.0-0
k8s.gcr.io/coredns/coredns:v1.8.4

多数image都有在registry.cn-hangzhou 中，但是coredns的路径不对

root@test-k-1:~# kubeadm config images pull --image-repository=registry.cn-hangzhou.aliyuncs.com/google_containers
[config/images] Pulled registry.cn-hangzhou.aliyuncs.com/google_containers/kube-apiserver:v1.22.1

能下载的地址是

root@test-k-1:~# docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/coredns:1.8.4 
1.8.4: Pulling from google_containers/coredns
Digest: sha256:6e5a02c21641597998b4be7cb5eb1e7b02c0d8d23cce4dd09f4682d463798890
Status: Image is up to date for registry.cn-hangzhou.aliyuncs.com/google_containers/coredns:1.8.4
registry.cn-hangzhou.aliyuncs.com/google_containers/coredns:1.8.4

为什么coredns的tag，在gcr是v1.8.4 ，而同步到registry.cn-hangzhou后是1.8.4
