Deploying our application image on dockerhub
Firstly, we have to manage our expectations. Similar to NGINX, automating deployment processes is a book in itself. In fact, there is a whole profession around it, called DevOps.
In this section, we will cover some basic automation processes. However, it has to be noted that this is not state of the art.
