Upload your own image on Docker Hub
One of the very first steps in the containerization process of a service or application is constructing the image that is going to be used for every component. A component may require a plain image that is just an Apache server, but in the majority of the cases, you'll have to add packages or apply configurations to the images already provided in Docker Hub. This will result in creating your own images that you may eventually share on Docker Hub. In this post, we're going to follow the process of creating our own image and then publishing it.
