3.docker pulls the image that exists on docker hub to local (download the image on Docker hub)
[root@www ~] # docker pull httpd:2.4.37-alpine2.4.37-alpine: Pulling from library/httpd4fe2ade4980c: Already exists42101a4e4c4e: Pull complete73eadb9961ff: Pull complete830983fb5ec2: Pull complete78fb51bbfc27: Pull completeDigest: sha256:b875793145fe613aa2d1f73f1cd8ec09b775abcd6980024bc60a6a9c73d644fcStatus: Downloaded newer image for httpd:2.4.37-alpine [root@www ~] # docker image lsREPOSITORY TAG IMAGE ID CREATED SIZEhttpd 2.4.37-alpine 11fc0c2a2dfa 4 days ago 91.8MBnginx 1.14-alpine 77bae8d00654 13 days ago 17.7MBljymyy/nginx latest 77bae8d00654 13 days ago 17.7MB
4. Make an image based on the container
[root@www] # docker container run-- name httpd1 httpd:2.4.37-alpineAH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 172.17.0.2.

5. Tag the image; (IMAGE ID is the same)
[root@www ~] # docker tag ljymyy/httpd:private ljymyy/httpd:v2.0 [root@www ~] # docker image lsREPOSITORY TAG IMAGE ID CREATED SIZEljymyy/httpd private 0c28c4522c12 5 minutes ago 91.8MBljymyy/httpd v2.0 0c28c4522c12 5 minutes ago 91.8MBhttpd 2 .4.37-alpine 11fc0c2a2dfa 4 days ago 91.8MBljymyy/nginx latest 77bae8d00654 13 days ago 17.7MBnginx 1.14-alpine 77bae8d00654 13 days ago 17.7MB
6. Upload the local image to the docker hub library
Create a personal Repository; in dashboard on docker hub to create the corresponding namespace and repository name; for example: ljymyy/httpd
