I was told it's better not to use latest in Docker File, but how can I find alternatives?

According to: https://ubuntu.com/download/desktop the latest version of ubuntu is Ubuntu 22.04.1 LTS but when I go to: https://hub.docker.com/_/ubuntu/tags I see strange tags like: bionic what is that?

and 22.10 this is a future version? how is that possible?

and while I could fine 22.04 I could not find 22.04.1

There are many problems involving the usage of latest tag on a docker image. The application is constantly changing and with it its architecture as well. While pulling an image with the latest tag, you use these changes as well. This may be good in a personal project sometimes but in a large scale application, you dont want your application to change drastically. Example:

• While working on a dockerized application, we incorporated db connector to session storage redis db, the connector connected to redis at the start of the application and if it was unsuccessful, the application would not start. Every update/change on the host machine with running application meant deploying redis as well as we were using the latest tag.

22.04 Ubuntu is the latest LTS build, but there also is experimental 22.10 (ref. Ubuntu 22.10
