1.Docker Hub
A warehouse is a centralized place for storing images.
At present, Docker official warehouse maintains a public warehouse https://hub.docker.com, which already includes more than 15,000 mirrors.
Most of these requirements can be achieved by mirroring directly in the Docker Hub.
The login
You can login by running the docker login command to enter the user name, password, and email address.
Basic operation
Users can use docker search command to find the image in the official warehouse without login, and download it to the local using Docker pull, and push the local image to the Docker Hub through docker push command.
Tag a copy of the image and push the image to the server
2. Create and use private repositories
Create a private repository using the Registry image
A set of local private warehouses can be built by the registry image officially provided by Docker.
Image address: https://hub.docker.com/_/registry/
Command:
docker run -eSEARCH_BACKEND=sqlalchemy-eSQLALCHEMY_INDEX_DATABASE=sqlite:////tmp/docker-registry.db-d –name registry -p 5000:5000 registry
-e Sets environment variables
-d Indicates that the mirror is started in background mode
-name Specifies a name for the started container
-p exposes the port. 5000 inside the container is bound to port 5000 on the host.
Registry image itself
SEARCH_BACKEND= SQLalchemy The default index is queryable
Reference Address:
https://github.com/docker/docker-registry#search-engine-options
https://hub.docker.com/_/registry/
Automatically downloads and starts a Registry container to create a local private repository service.
The default repository is created in the/TMP /registry directory.
Upload it to a local private warehouse,

Docker startup parameter configuration:
Environment: centos7 addresses this issue
The configuration file: / lib/systemd/system/docker. Service
Modified to:
#ExecStart=/usr/bin/dockerd
ExecStart = / usr/bin/dockerd -h TCP: / / 0.0.0.0:2375 – H Unix: / / / var/run/docker. The sock, insecure – registry192.168.100.146:5000
(the default port 2375 as the main management, Unix: / / / var/run/docker. The sock for the local management, 7654 is spare port)
Restart the service, start a private repository container, and then push it to the private repository

3. Warehouse acceleration service
Speed up the download of official images.
Recommend a service: https://dashboard.daocloud.io/
Click on the accelerator: https://dashboard.daocloud.io/mirror
Docker accelerator configuration:
Download the third-party official warehouse.
4. Warehouse management
Registry Web UI
Used for mirror query, deleted.
Mirror address: https://hub.docker.com/r/atcol/docker-registry-ui/
Start command: When running the following commands, it is recommended to configure the acceleration mentioned above, because there are a lot of things to download.
Docker run – d – nameregistry_ui – p, 8080:8080 – e REG1 = http://172.17.0.2:5000/v1/atcol/docker-registry-ui
Check whether the port is enabled
