Warehouse Mirror
 Docker hub has officially provided a container mirror registry for building private warehouses
 # docker imagers # Check out what mirrors you have

1. Pull the mirror:

# docker pull daocloud.io/library/registry:latest

2. Operating containers:

# docker run --name "pri_registry" -- restart = always-d-p 5000:5000 daocloud.io/library/registry//restart = always: boot-up is self-starting, and service reboot will follow. Mapping to the host's 5000 port, and its own 5000 port-d is used in the background.
#docker ps                    #Take a look at the startup status
//Note: If the creation of containers is unsuccessful, the error firewall is reported. The solution is as follows.
   #systemctl stop firewalld
   #yum install iptaqbles*
   #systemctl start iptables
   #iptables -F
   #systemctl restart docker
   
# docker ps
CONTAINER ID  IMAGE  COMMAND   CREATED  STATUS    PORTS    NAMES
1f444285bed8        daocloud.io/library/registry   "/entrypoint.sh /etc/"   23 seconds ago      Up 21 seconds       0.0.0.0:5000->5000/tcp   elegant_rosalind

3. Connect the container to view port status:

# Docker exec-it 1f444285bed8/bin/sh//Here is sh, not bash
/# Netstat-lnp//Check whether the 5000 port is open
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
tcp        0      0 :::5000                 :::*                    LISTEN      1/registry
Active UNIX domain sockets (only servers)
Proto RefCnt Flags       Type       State         I-Node PID/Program name    Path

#ctrl+q+p exits the edit page, but does not exit the container

4. Check whether the private warehouse can be accessed locally to see if the status code is 200.

[root@master registry]# Curl-i 127.0.0.1:5000// parameter is capitalized i
HTTP/1.1 200 OK        

For convenience, download a smaller image, buysbox

# docker pull busybox

Before uploading, the image must be tag ged with ip and port:

# docker tag busybox native IP: port/busybox

This is a mirror drawn directly from the official, very slow:

# docker tag busybox 192.168.245.136:5000/busybox

The following Mysql is the second image I tested, pulled from daocloud:

# docker tag daocloud.io/library/mysql 192.168.245.136:5000/daocloud.io/library/mysql
 Note: You can use mirror name or id after tag. I use mirror name here. If you use official image, you don't need prefix, but daocloud.io's
 Prefix

The following error reporting problems are inevitable:

Modify the request to http:
    The default is https, and the following errors will not be reported.
        Get https://master.up.com:5000/v1/_ping: http: server gave HTTP response to HTTPS client
    
    # vim /etc/docker/daemon.json
    { "insecure-registries":["192.168.245.136:5000"] }

Restart docker:

# systemctl restart docker

Upload mirror to private warehouse:

# docker push 192.168.245.136:5000/busybox  #Push it to a private warehouse

# docker push 192.168.245.136:5000/daocloud.io/library/mysql

Look at all the mirrors in the private warehouse:
Note that I'm using the example of ubuntu here.

# curl 192.168.245.130:5000/v2/_catalog
        {"repositories":["daocloud.io/ubuntu"]}

    //Or:
        
# curl  http://192.168.245.130:5000/v2/daocloud.io/ubuntu/tags/list
        {"name":"daocloud.io/ubuntu","tags":["v2"]}
    
//Mirror testing can be pulled out:
#docker pull    192.168.245.136:5000/busybox
