Origin of Docker
Solomon Hykes, who was working at the time for the cloud hosting company dotCloud, was the one who came up with the idea for Docker. It was back in 2013. It was initially developed as a tool for internal use to simplify developing and deploying software applications.
Linux containers have been around since the early 2000s, but Docker containers weren’t widely used until Docker created a simple platform for running containers. It got the attention of both developers and system administrators. Docker containers are based on Linux containers. Docker made its technology open-source in 2014, and it quickly became one of the most popular projects on GitHub. Soon after, the company raised millions of dollars from investors.
How is Docker working?
Docker is software that enables users to construct, run, test, and deploy distributed applications. It distributes software in containers by employing virtualization at the level of the operating system.
Docker does so by enclosing an application and all of its prerequisites in a portable, cloud-based virtual container that can function on any host. Compared to virtual machines, this containerization enables far higher portability and efficiency than was previously possible.
These containers are separate from one another and come with their tools and configuration files. They are also sandboxed. They can speak with one another through routes that have been clearly outlined. Because just one operating system’s kernel is responsible for running each container, the overall resource consumption is low.
As was stated, operating system virtualization has been available for a while in the shape of Solaris Zones, FreeBSD jail, and Linux Containers. On the other hand, Docker took this idea one step further by creating a platform that was both simple to use and capable of automating the process of deploying apps inside containers.
Conclusion
Docker is a powerful solution that may assist you in automating the deployment of your apps in a way that best suits your needs. It is easy to use, and you are not required to install any dependencies on the machine that you are using as the host.
Docker has quickly emerged as one of the most popular technologies for creating and deploying software over the past several years. Developers use it to compile their source code and all of its dependencies into a standardized package that can be installed on any server afterward. Docker is an excellent solution for developing microservices because it enables developers to execute several apps in isolation on a single host. This feature alone makes Docker an excellent choice.
Suppose you’re looking for a solution that will help you simplify your workflow and make your life as a developer and system administrator easier. In that case, Docker is an essential piece of software to have in your toolbox.
