Kubernetes: DaemonSet

Kubernetes is one of the widely used orchestration tools for container application and container management. With a variety of features and options, it helps organizations remove manual intervention at every stage. With lots of requirements & scenarios, the user or any organization deals with lots of Kubernetes resources types options which leads to having proper knowledge of every Kubernetes resources type to fit specific or combination of resources with different scenarios that organizations generally require. To know more about different Kubernetes resource types, you can visit the official documentation provided by Kubernetes.

This blog will cover one of the Kubernetes resources which are only used for a specific use-case. There are multiple resources where we can leverage those resources at specific use-case, but for now, we are only focusing on DaemonSet which is very important and has a unique functionality that we cannot cover by using another pod controller.

As of late, I took a dive at setting up and connecting WordPress with the database using container services. I created a website but couldn’t figure out where and how to deploy it. I was looking for a way with less exertion, at least expense, and minimum time. At this point, I thought of a Continue reading “BuildPiper – A SAAS Playground”

Redis Setup on Kubernetes

Redis is a popular and opensource in-memory database that supports multiple data structures like strings, hashes, lists, and sets. But similar to other tools, we can scale standalone redis to a particular extent and not beyond that. That’s why we have a cluster mode setup in which we can scale Redis nodes horizontally and then distribute data among those nodes.

Since Kubernetes is becoming buzz technology and people are using it to manage their applications, databases, and middlewares at a single place. So in this blog, we will see how we can deploy the Redis cluster in production mode in the Kubernetes cluster and test failover.

Gif for Fasten Docker Build


Recently I started working on a microservices project, as a DevOps engineer my responsibility was to ensure smooth build and release of the project. One of the challenges that I was facing was the image building process of the projects was painfully slow. Following true Opstree spirit of continuous improvement I started exploring how I can fix this problem and finally got a decent success, I was able to reduce docker image build time from 4 minutes to 20 seconds. In this blog, I would like to showcase various ways through which image building can be reduced drastically.

Create Your Own Container Using Linux Namespaces Part-1.

In this lock-down, everyone has to maintain a social distance and in this trying time, we can learn from docker to isolate ourselves. So before that, we need to learn how docker does it?
The best approach to learn is to simulate it. For that, we’ll be creating our own container tool for the application to isolate itself.
