TL; DR
root@tencent-sh1:~# cat /etc/rancher/k3s/registries.yaml
mirrors:
"docker.io":
endpoint:
- "https://harbor.xxx.me"
rewrite:
"^(.*)": "mirror-dockerhub/$1"
"registry.k8s.io":
endpoint:
- "https://harbor.xxx.me"
rewrite:
"^(.*)": "mirror-registry-k8s-io/$1"
"ghcr.io":
endpoint:
- "https://harbor.xxx.me"
rewrite:
"^(.*)": "mirror-registry-ghcr-io/$1"
"quay.io":
endpoint:
- "https://harbor.xxx.me"
rewrite:
"^(.*)": "mirror-registry-quay-io/$1"以上是我的配置，在 harbor 中镜像以上镜像源，之后这样 配置即可。
如果没有路径，比如使用 registry 镜像，忽略 rewrite 部分即可。
