How do I execute a docker container

I created the images locally and created one repository in DockerHub called testName/backend.

The docker images command shows the created images.

 REPOSITORY              TAG              IMAGE ID       CREATED          SIZE  
    testName/backend       0.0.1-SNAPSHOT   10fc47e065ff   25 minutes ago   459MB 
    backend                 0.0.1-SNAPSHOT   10fc47e065ff   25 minutes ago   459MB 
    backend                 latest           2f5cc7be2b5d   41 minutes ago   479MB 
    alpine/git              latest           22a2874e1112   3 weeks ago      39.5MB
    hello-world             latest           feb5d9fea6a5   10 months ago    13.3kB

And I would like to run the container with a command in the format docker run yourImage:version. So according to this (so I think I should call such a command: docker run 10fc47e065ff:0.0.1-SNAPSHOT
However, I get this message: Unable to find image ’10fc47e065ff:0.0.1-SNAPSHOT’ locally
docker: error response from daemon: pull access denied for 10fc47e065ff, repository does not exist or may require ‘docker login’: denied: requested access to the resource is denied.

I will add that I am logged in.

What am I doing wrong that I can’t get the container to work?

By the way, I have a question about the docker in the context of the application. Generally, in this image there is a Spring Boot + Angular application. I am uploading it to a container, and spring + angular is supposed to work together with each other . And generally the question I have is whether I will have to create a new image every time I make a modification to the application code, or if I run the application using the docker run command then the image will be automatically overwritten and every time I run the application I will get the "latest version" of the application.
