Host Operating Systemand aHypervisorand on top of all that eachVMhas its ownOSand all necessary libraries. ForDocker, the host server only has the infrastructure and theOSand on top of that, the container engine, that keeps container isoloated but sharing the baseOSservices....
These lightweight, portable, and self-contained environments have transformed how applications are built, shipped, and run. At the forefront of containerization technologies is Docker. In this article, we will delve into containers and Docker, providing a comprehensive introduction to these game-...
In this example, Docker host is a container host, and App1, App2, Svc 1, and Svc 2 are containerized applications or services.Figure 2-1. Multiple containers running on a container hostAnother benefit of containerization is scalability. You can scale out quickly by creating new containers ...
A Docker image is a template containing the application details plus all the necessary libraries and binaries that are required to create a Docker container. These images are stored in a public repository or registry called Docker Hub. The Docker image is built using the Dockerfile. A Dockerfile...

Docker, Kubernetes, Red Hat OpenShift, and Istio. Containerization is likely the most significant invention in IT since the introduction of virtualization. Open source projects like Kubernetes and products like Red Hat OpenShift have become standards for people looking to deploy and manage containers...
Embark on a comprehensive learning path to understand Docker and containerization, beginning with foundational concepts and installation procedures. Progress through hands-on exercises that cover essential Docker commands, image creation, and container orchestration. ...
Since Docker engine runs containers it also termed as containerization! Why use Docker? Docker containers are portable.They can be stored as an image which can be copied to any other machine and can be launched there. This ensures even if host OS parameters, version changes containers still fu...
In continuing thisDevOps Basicsseries, it is now time to learn the basic commands to properly enable use of Docker. Introduction and Quick Concepts I don’t want to go very deep on the containerization’s concepts but here some important concepts to understand with Docker / Co...
Docker is written to run natively on the Linux platform, and the host and container OS must be the same. Wait a minute. If the host and container OS must be the same (that is, Linux), how do you run Docker on operating systems such as Windows and macOS? Turns out that if you're...
