In this chapter, we have been using Docker during the build process of the Java applications using Maven. We know that there are a couple of Docker plugins for Maven and we know their functionality and limitations. To give you an idea of how to package your own applications into the container, we have run Java and JavaScript applications using Docker. Of course, this is just the tip of the iceberg, but I hope you were given some inspirations to package your own applications, no matter what language or framework you use. Having the Docker knowledge you have acquired so far, you will be able to pack any application that you wrote into the container and publish it on the Docker Hub. The world of Docker is enormous today, there's a lot to explore. Further in the book, I will point you to other resources that I find very useful; you can use them to further extend your Docker knowledge base.
