Background of the problem
Login your docker hub account in Linux
Upload local image but report error
docker push tomcat
Solutions
docker tag tomcat poloyy/tomcat:77
Make a new tag for the image that needs to be uploaded
The applicable formula is: docker tag image to upload [: tag] [docker hub registered account name]/image name [: tag]
Tomcat: the name of the image to be uploaded. Tag can be specified
Poly: it’s my docker hub account. You can change it to your own account here
poloyy/ tomcat:77 : means that the Tomcat warehouse under the poly account is generated and labeled 77
