Virtualization

This article focuses on the benefits of migrating to a new distributed architecture. Containers have taken the DevOps world by storm and streamlined the software deployment process. Almost all applications can be containerized. Use this tutorial to find out where to start and what to look out for.

This article shows you how to port forward from your localhost and interact with Kubernetes cluster resources. Use port forwarding to work on and debug your services locally. There is now no need to expose your services beforehand.

This tutorial shows you how to use Docker and an official MongoDB container image to deploy your databases. Additionally, it covers basic commands that allow you to interact with the MongoDB client effectively.

CMD is Docker instruction used if you need a default command which users can easily override. ENTRYPOINT is used when you want to define a container with a specific executable. You cannot override ENTRYPOINT when starting a container. Combine ENTRYPOINT with CMD if you need to have a container with a specified executable and a default parameter which can easily be modified.

Kafka collects and structures vast amounts of data from multiple clients simultaneously. It's a great integrating component that improves the efficiency of applications running in a cluster. Use this article to find out how to configure a Kafka server on your Kubernetes cluster.

Deploying MySQL in a container is a fast and efficient solution for small and medium-size applications. Instead of setting up a separate MySQL server, you can deploy a MySQL database container instead. These containers are lightweight and fast to spin up since they share the kernel and libraries of the host while packaging the deployed application.

Persistent Volumes are used in Kubernetes orchestration when you want to preserve the data in the volume even after a specific pod has finished claiming it. It is a way of connecting a container to external storage through a series of abstractions. Learn more about this useful Kubernetes feature here.

This article presents basic security principles such as defense-in-depth and restricted privilege. Learn how to apply these principles in a distributed system such as a Kubernetes cluster.

CentOS 8 does not provide official support for Docker. This article clearly shows you how to install a fully functional version of Docker regardless.

Container deployment took the software development world by storm. Use the outlined guidelines and learn how to get the most out of the container images and Kubernetes. The more of these concepts you apply in practice, the more effective your system will be.
