Docker is currently the most invaded and popular container platform in the technological world. They have been open source from their inception and this has led Docker to dominate the current technology market. Currently, 30% of enterprises use Dockers in their AWS ecosystem and the number continues to develop. 


The essential elements necessary to run a Docker container should be built before it can be run. Docker is the most efficient tool that makes it easier to create, deploy, and run applications by using containers. It is designed to benefit both developers and system administrators, making it a part of many DevOps (developers + operations) toolchains. For developers, it grants them the freedom to focus on writing code without worrying about the system that it will ultimately be running on. It also allows them to get a head start by using one of the thousands of programs already designed to run in a Docker container as a part of their application. For the operations team, Docker gives flexibility and potentially reduces the number of systems needed because of its small footprint and lower overhead.


However, with a large number of teams adopting Dockers to follow trends, there are a few gaps we often come across in the usage of Dockers. These gaps often lead to critical cost, performance and security issues. Here are a few tips with which these gaps can be avoided or mitigated. Note that these are basic checkboxes for your Docker setup. One size doesn’t fit all is still applicable and you should tweak these based on your use case. 














On the whole, Docker possesses the capability to get more applications running on the same hardware than other technologies, it makes it easier for developers to quickly create ready-to-run containerized applications. Docker also helps in managing and deploying applications much easier.
