CRProxy (Container Registry Proxy)

CRProxy is a generic image proxy

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

crproxy + registry(pull through cache mode)

• for organizations and companies which need to serve big clusters
• container-image-mirror
  • deploy into k8s with argocd
  • storage with pvc, s3(minio/oss compatible)
  • bind ssl with cert-manager and ingress

On Docker

Just add the prefix m.daocloud.io/

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
