If you enter the bash environment of Docker Mirror?

  docker, question

Some images downloaded from the image warehouse can be directly operated. For example, a wordpress image library can be accessed through an external network when it is operated. Like this mirror image,How do you enter the running bash environment??

For some really deployed projects, maybe the web part, the web server, the database, these areIs it better to make the images separately and then access the images after running, or is it better to put them in the same container?

Login container

docker exec -it container-id/container-name bash
