isxzlhhh: 问题：由于国内
docker.io 镜像仓库关闭了，所以想配置镜像加速，但是配置好像一直没有生效，还是从官方仓库拉取镜像

certs.d 目录下有三个目录（

registry.k8s.io->hosts.toml

使用 ctr 拉取镜像，还是拉取不了
root@localhost:/etc/containerd/certs.d/
registry.k8s.io# ctr --debug images pull
docker.io/library/nginx:latestDEBU[0000] fetching image="
docker.io/library/nginx:latest"

但是还有个奇怪的问题就是 使用 crictl 拉取镜像是能够正常拉取的
root@localhost:/etc/containerd/certs.d/
registry.k8s.io# crictl pull nginx:latest
Image is up to date for sha256:47ef8710c9f5a9276b3e347e3ab71ee44c8483e20f8636380ae2737ef4c27758
这个问题困扰小弟很久了，跪求各位大佬帮忙看看是啥问题
