docker public registry and private registry

Private registry
$ mkdir repo

X86
$ docker run -d -p 5000:5000 -v $(pwd)/repo:/var/lib/registry --restart=always --name registry registry:2

Arm64:
$ docker run -d -p 10000:5000 -v $(pwd)/repo:/var/lib/registry --restart=always --name registry gaozhangfei/arm64v8/registry:1

Ps:
No standard registry for arm, provide https://hub.docker.com/r/gaozhangfei/registry/

//How to support multi-registry
// solve issue: docker registry push “server gave HTTP response to HTTPS client”
$ vi /etc/default/docker
