Add the prefix m.daocloud.io/ to all places that need to use images

• English
• 简体中文

m.daocloud.io

you can deploy your own image proxy server if you need to.

Refer to

On Docker

docker pull m.daocloud.io/docker.io/library/busybox

On Kubernetes

Just add the prefix m.daocloud.io/

image: m.daocloud.io/docker.io/library/busybox
