1. Install docker
Yum install libdevmapper *-y
Yum install docker-y

Systemctl start docker. service
Systemctc enable docker

3. Set the docker image source accelerator

Curl-sSLhttps: // get. daocloud. io/daotools/set_0000.sh | sh-shttp: // ef017c13. m. daocloud. io
Note: The/etc/docker/daemon. json file is generated for the first time, and the {"registry-mirrors": ["http://48b042ae.m.daocloud.io"]} configuration parameters are written.

Cat/etc/docker/daemon. json
{"Registry-mirrors": ["http://ef017c13.m.daocloud.io"],
"Live-restore": true
}

Download a registry Image

Docker pull registry

4. Start the registry container

Docker run-d-p 5000: 5000-v/opt/data/registry:/tmp/registry

5. Configure the local deamon. json file and add the following parameters:

"Insecure-registries": ["192.168.1.14: 5000"] # This parameter solves the problem of http: server gave HTTP response to HTTPS client.

Cat/etc/docker/daemon. json
{"Registry-mirrors": ["http://ef017c13.m.daocloud.io"],
"Insecure-registries": ["192.168.1.14: 5000"],
"Live-restore": true
}

6. pull test images from the official website
Docker pull redis

7. Tag The test image
Docker tag redis 192.168.1.14: 5000/localredis: 01 # note that the database name cannot contain uppercase letters

8. upload to the local repository
Docker push 192.168.1.14: 5000/localredis: 01

9. delete a local image
Docker rmi 192.168.1.14: 5000/localredis: 01

10. Access through http api
Curl 192.168.1.14: 5000/v2/_ catalog

Curl 192.168.1.14: 5000/v2/localredis/tags/list
{"Name": "localredis", "tags": ["01"]}

11. Pull the local repository image (for other nodes, configure/etc/docker/daemon. json according to 5)
Docker pull 192.168.1.14: 5000/localredis: 01
