The tagline of Docker says, ‘Developers bring their ideas to life with docker.’
Such a powerful technology, “Docker is an open-source engine that automates the deployment of any application as a light-weight, portable, self-sufficient container that will run virtually anywhere.”
Development of applications requires not only code writing but a complete knowledge of frameworks, infrastructure, multiple languages, architectures, and discontinuous interfaces between tools required for each stage of the life cycle that creates complexity.
Thanks to Docker that simplifies and whisks your workflow and gives the developers the freedom to innovate their choice of tools, deployment environments, and application stacks for each project.
Put simply, Docker is a container that allows you to execute your application anywhere and forget about the worries of hardware, versions of operating systems that make it easy for you to develop a new environment with no configuration worries.
It provides you with a container and a command-line tool to maintain those containers.
While Docker allows you to deploy your applications irrespective of the environment, it provides flexibility to developers and administrators, which is why it is preferred by tech giants Microsoft and Google.
On the other hand, Kubernetes is a container orchestration system meant for maintaining containers effectively. It is the most essential and effective container management technology and is utilized in a real production environment that allows you to manage multiple containers simultaneously.
It is easy to orchestrate a handful of applications and containers at once, but when the number increases to hundreds or thousands, it becomes challenging. Here, Kubernetes becomes a game-changer that helps you to manage, automate, and scale the applications that are containerized.
If you wish to learn the technology and acquire Docker Certification Training, then there are many resources that train you online, some of them possessing top features that an ideal training course should possess. Here is a list of top online training courses handpicked for you that you can consider before going with training.
