Is Docker a real game changer for Container Management?


Docker is gaining popularity in this fast-growing IT world. Organizations are continuously adopting docker in their production environment.

Docker is a containerization platform, and Solomon Hykes developed it and promoted it by Docker.Inc. The Docker was born in France, as an internal project of dotcloud, the company of Hykes. Then many people kept modifying and enhancing them. The advancement and a series of amendments led to this current Docker software.

In 2013, in Santa Clara, PyCon brought this to the public. Later in the year, it was offered as open-source written in Go language. It’s been six years since the docker came into existence.

What is Docker?

Docker is an all-purpose tool that packages, provisions, and runs containers independent of the OS. It also possesses the capabilities of a Platform and Software as a Service. Docker is the virtualization of the operating system; which denotes the development and delivery of products and packages in the form of containers.

The Docker’s Engine is the host of all the actions taken and executed. It works on a freemium subscription. The basic services are free, while for advanced features users can go with premium subscription series.

Layers of Docker container are the building blocks of software. They own their particular traits and files. The transfer of information among the containers is carried out through the defined channels. The ringmaster of all operating containers is the Kernel which is pretty light and advances.

When Microsoft and Docker teamed-up.

Microsoft held Docker’s hand in the year 2014; the windows allowed docker for application execution. Now docker supports the building, shipping and running on Windows. It was almost a revolutionary change. The concept of containers is now present in Windows as well, and it is known as Windows containers applicable with Windows 10 and Windows Server 2016.

This year, another angle popped out, Microsoft introduced the Windows subsystem Linux’s second version. A complete connection of Linux OS and Windows 10. DOCKER, after the announcement of this, announced a version that will work with WSL 2, not the full virtual machine.

Working of Docker.

Docker is a more efficient looking software as it uses lightweight containers that accelerate the pace of the execution. Linux said that “Docker is a tool that can package an application and its dependencies in a virtual container that can run on any Linux server. It provides flexibility and portability to run the application, whether on-premises, public cloud, private cloud, bare metal, etc.”

Uncomplicated handling gives it an advantage over others as any user can use it over any single server or virtual machine. But it can’t handle too much of workload as more than five containers per host disturbs working. Simplified working is an integral part of Docker.

Should You use Docker?

Docker has become a popular way of configuring, saving, and sharing server environments using containers. Because of this, installing an application or a large software can often be as easy as running docker pull or docker run. Separating application functions among various containers also offers benefits in security and dependency management.

However, Docker is not a like for like substitute for systems engineering or container management, and its approach also has drawbacks. Developers should resist the temptation to containerize each application they create, simply because Docker is an accessible and easy-to-use solution. As with any tool, before deciding whether to use Docker, the requirements of every project should be carefully investigated.
