Docker

There are lots of importance of Docker in DevOps methodology, some of them we are going to explore in this article. So, let us first understand “What is Docker?”. Docker is a containerization platform that enables developers to package and run applications in isolated environments. It plays a crucial role in DevOps, combining software development […]

Docker is a containerization platform that enables developers to package and run applications in isolated environments. Within Docker, there are two important concepts: Docker images and containers. Docker Image A Docker image is a non-modifiable template that contains the necessary files and instructions to build a Docker container. Images are created using a Dockerfile, a

A Docker registry is a central repository for storing and distributing Docker images. Docker images are a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries, and settings. Docker registries can be public or private. Public registries, such as Docker Hub, allow anyone to

Containers and virtual machines (VMs) provide isolated environments for running applications, but they have distinct differences. Containers Containers are lightweight and share the host operating system’s kernel, making them efficient. However, they are less isolated from the host OS. Containers are ideal for deploying microservices and testing applications in development environments. Virtual Machines (VMs) VMs

Docker is a containerization platform that enables running applications in isolated environments. Containers in Docker share the underlying host operating system’s kernel, making them lightweight and efficient. The mechanism behind Docker’s kernel sharing is based on Linux kernel features like namespaces and cgroups. Namespaces provide containers with their own view of the filesystem, network, and
