I’d like to discuss what reading I’d recommend starting learning the Rust Programming Language and how useful the language can be, not only to Systems Programming, but also to Microservices, web development, applications in Blockchain technology; even game development.

Hello everyone. We are going to start a Kubernetes series. In this series, we will learn the basics of Kubernetes and try to deploy our sample microservice code with Kubernetes.

Disclaimer :) If you don’t have prior knowledge of Docker, please refer to this blog. It will help you to understand Kubernetes more precisely.

Over the past years, containerization has increased demand as a powerful solution to application deployment and migration; however, this has not fallen short of challenges; among them security risks.

[GKE] End to End setup of Multi Region Autopilot Kubernetes Cluster with Application Deployment Example

We are going to deploy an Active-Active Architecture Multi-Region Kubernetes Cluster with Terraform in this story.
This will make our cluster highly available since we have two different clusters to serve the traffic and fault tolerant since we are deploying both clusters in different regions. In the worst case even if one region goes down, we will be able to serve traffic from second region cluster.

In my previous story we configured KEDA on Kubernetes. Today we will configure our Autopilot Kubernetes cluster on Google cloud platform with multi region support, and we will deploy a sample application with ingress to verify that traffic is getting served from both the clusters.

Recommendation :) Docker-compose built on top of the Docker container engine. To know more about Docker please follow this article which will give you a good sense to read this article.

Unit testing is the most important thing in developing an application, which aims to minimize the occurrence of errors, therefore software developers are obliged to master it. In this article, we will write unit tests in the Golang programming language using the unit testing package provided by Golang.

Let’s get started!

The calculator application is a simple application that is always available on every device such as android, ios, and desktops. In this article we will build a calculator application using React Native and Expo, why do we use React Native and Expo?

React Native is a JavaScript-based framework that is used to develop mobile applications on two operating systems simultaneously, namely Android and iOS. React Native itself was first launched in 2015 by Facebook and is open source.

You can find out more information about React Native here

Expo itself is a set of tools, libraries, and services that are used to simplify the code of React Native apps. So you can run React Native apps on the Expo emulator.

You can find out more information about Expo here.

maybe that’s enough about the introduction of React Native and Expo. Before we start making a calculator application, first install node js, react native, and expo on your computer.

We often come across some weird scenarios (especially my team) while committing our code changes. Some of them are,

How can I bring the file to working area, which I have added to the staging area by mistake?

OMG! I made a commit with production keys in the code but did not push the code yet. Is it possible to delete that commit? (Meanwhile, my tech lead be like 😡)

Can anyone say how to remove the changes which I’ve pushed already?

I logged onto Production machine and made a change to a file and fixed the production issue immediately 👏 (Can also be debugging on production 😜). Now, I want to remove that change using git cli for the CI/CD to pass. Any Git commands available for this purpose?

Head to the bottom of this page, if you need blind answers for these scenarios. For those who need to understand more, continue from here.

Let’s find answers to all of your such queries with just 3 commands.
