docker 镜像删除后会把所有的数据和文件都删除，所以要把宿主机的本地目录挂载到registry容器内部的目录上，在删除registry容器后依旧能保证文件和数据不丢失

meiya@meiya:/etc/docker$ mkdir -p ~/docker/data/registry

Get https://192.168.1.57:5000/v2/: http: server gave HTTP response to HTTPS client
meiya@meiya:~/docker/data/registry$ 

这里出了个问题  ，主要是因为docker新版本默认不支持https协议，开放https协议

Get https://192.168.1.57:5000/v2/: http: server gave HTTP response to HTTPS client

解决办法，修改docker的配置文件，

修改默认的配置文件

sudo vi /etc/default/docker

加入

DOCKER_OPTS="--registry-mirror=https://registry.docker-cn.com --insecure-registry=192.168.1.57:5000"

# Docker Upstart and SysVinit configuration file

#
# THIS FILE DOES NOT APPLY TO SYSTEMD
#
#   Please see the documentation for "systemd drop-ins":
#   https://docs.docker.com/engine/admin/systemd/
#

# Customize location of Docker binary (especially for development testing).
#DOCKERD="/usr/local/bin/dockerd"

# Use DOCKER_OPTS to modify the daemon startup options.
#DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"

DOCKER_OPTS="--registry-mirror=https://registry.docker-cn.com --insecure-registry=192.168.1.57:5000"

# If you need Docker to use an HTTP proxy, it can also be specified here.
#export http_proxy="http://127.0.0.1:3128/"

# This is also a handy place to tweak where Docker's temporary files go.
#export DOCKER_TMPDIR="/mnt/bigdrive/docker-tmp"

重启docker服务， 重启registry容器，重新push本地镜像

meiya@meiya:~/docker/data/registry$ docker ps

ps:

第二种办法是修改  /etc/docker/daemon.json 文件，重启docker服务， 重启registry容器，重新push本地镜像

meiya@meiya:~/docker/data/registry$ cat /etc/docker/daemon.json
{
    "registry-mirrors": ["https://hdokp13m.mirror.aliyuncs.com"],
    "insecure-registries":["192.168.1.57:5000"],
    "registry-mirrors": ["https://registry.docker-cn.com"]
}

查看私有仓库中的镜像

meiya@meiya:~/docker/data/registry$ curl get http://192.168.1.57:5000/v2/_catalog
