In the blog section of the Opera VPS site, we have already introduced you to Docker. As a result, Docker facilitates the management and execution of programs, which makes it possible to run programs independently of resource processes. The runtime of a program is enclosed in a container that contains the software and hardware components necessary for the program to function.ĭocker is widely used in today’s continuous integration and deployment (CI/CD) pipelines for software development and DevOps operations.Ĭontainers have something in common with virtual machines, except that they can be moved more easily, use less system resources, and rely on the host operating system.

Similarly, containers are isolated from each other (and the underlying host system) but can still exchange data via standard protocols.ĭocker is an open-source containerization technology that facilitates the development, testing, and deployment of applications in the form of self-contained containers and creates and manages containers for application development.ĭocker is a modern platform for rapid development and innovation that is used to automate the deployment of applications in lightweight containers so that applications can run efficiently in different contexts.

All the code, libraries, data, and configurations of an application, tool or service are packaged into a container. Docker originates from a collection of “platform-as-a-service” products and services that deliver packages known as ‘containers’ through operating system virtualization technology.
