Docker Roadmap for Beginners
Docker is a platform that enables developers to package applications and their dependencies into lightweight, portable containers. Containers ensure consistency across development, testing, and production environments, making Docker a fundamental tool in modern DevOps workflows. This roadmap will help you learn Docker step-by-step and build a solid foundation as a beginner. Why Learn Docker? • […]
Kubernetes: How Blue-Green Deployment works?
Blue-green deployment involves simultaneously operating two application environments within a production cluster. In this deployment approach, the stable version of the application is deployed in the first environment (blue), while the new version is deployed in the second environment (green). By default, Kubernetes performs a rolling update of a deployment. As part of the rollout […]
How to get root access on the docker host filesystem?

How do I transfer a Docker image from one machine to another one without using a repository? Is the repository is mandatory to transfer the image between hosts? No. We can simply save the docker image as a tarball and transfer it to the remote host. You can import the docker image from the tar […]
Kubernetes Backup – Kasten K10 Test drive
The Kubernetes platform is fundamentally different from earlier compute infrastructures and IaaS. In Kubernetes, there is no mapping of applications to servers or VMs. so the backup solution needs to understand this Kubernetes-native architectural pattern, and be able to deal with continuous change. High-velocity application development and deployment cycles are the norms in Kubernetes environments. […]
Why Kubernetes Backup is so important ?
Containers are a flexible and efficient way to run IT tasks. Kubernetes is one of the most widely adopted container orchestration platforms. Containers have expanded to run a much wider range of processes, including full-scale applications. Docker Swarn and Apache Mesos are other container orchestration platform exist in the market. In recent times, most enterprise […]
