Imagine the next situation: You have only one laptop You have your personal GitHub account Your employer stores code on GitHub as well You need to commit your personal code to your personal repositories but also work code to the employer`s repositories.

A full-stack developer is someone who works on the front-end/client side of the application as well as the back-end/server-side of the application. Front-end web development is also known as client-side development is the development of the graphical user interface of a website, through the use of , , and JavaScript , so that users can view and interact with that website.

We will be deploying a containerized Node.js application using Docker over Google Kubernetes Engine using Jenkins for CI (building pipelines to build, test and upload image to Docker Hub) and argoCd with Helm for CD. It will sync up with our charts repo, pull images uploaded by Jenkins to dockerHub and accordingly apply changes to the GKE cluster infrastructure.

In our ongoing series, the Kubernetes FAQ, where we've been answering some commonly asked questions in the community, this week we discuss what you need to consider when choosing a CICD tool. There are a ton of CICD tools out there to choose from - both open source solutions as well as commercial ones.

A friend of mine recently decided to take up the journey of becoming a programmer. He's been passionate about tech longer than I have been, but never really got around to the software side. He purchased a mac mini, I pointed him to The Odin Project, and off he went.

I know you're here to virtually kick me in the teeth after reading the title, but hear me out for a second. In our industry we have these concepts of "best practices", "ideal architectures", "best programming languages", but these are all absolute statements that are never true in real life.

At Seeloz, we're building AI to reduce waste and inefficiencies in supply chain management. We've recently begun exploring migrating our big-data pipeline into Kubernetes. While we would highly recommended a startup use a managed Kubernetes solution, we've been given access to several powerful non-cloud VMs which we wanted to take advantage of.

Logging is vital for any software project, from development to ongoing management. Maintenance logs are crucial for determining the state of an application and monitoring and troubleshooting purposes. These days, logging is usually embedded throughout an application, from simple user access logs to database activity, error logs, and network flow logs.

So you are a backend engineer and you want to know how to deploy your services and set up CI/CD pipelines? This is a good first approach since you will know how to by doing. It is not going to be a...

In order to learn Ansible, we need some machines to configure (some people call these "servers" but there is a reason for the differentiation). Now, you could go to the local computer store and buy 5 machines, set them up, and you'd be good. Except that's pretty expensive, $1000+.

Installing from source using Ansible is the preferred method for new installations on Ubuntu. It is assumed here that your host operating system is Ubuntu. This can be modified for a different Unix based operating system, such as Mac OS X or another Linux distribution such as CentOS.

DevOps has fundamentally changed the way software is developed. It has further paved the way for creating faster, flexible, and more collaborative development and delivery processes. Thus, new and exciting DevOps tools emerge each year to improve existing workflows or introduce new functionality to the DevOps process.

DevOps has come a long way, and Kubernetes is quickly taking over the technology world. Kubernetes is an open-source container orchestrator system: it automates the deployment, scaling, and management of containerized applications. It is a powerful tool to manage distributed clusters of containers economically and reliably.

Docker Swarm is a container orchestration tool offered by Docker which provides cluster management and orchestration features embedded in the Docker Engine. Docker Swarm Mode, which was released in 2016, includes enhanced container services that has been optimised for clusters. This functionality allows applications to be easily deployed and scaled across the cluster with minimal effort and provides great efficiency.

Just setting up servers and deploying applications on them is not enough; it is also important that one can easily monitor the performance of all the servers from a centralized location for increased efficiency. This is where server monotony tools come in!

TLDR; I share what CLI tools I use on a daily basis on my terminal to improve my productivity. First things first, the command line is awesome. It makes me so much more productive by not having to move my hands to the mouse - I don't have words for it.

A huge part of what makes Chrome such a widely-used product is how expandable it is and Chrome extensions have had a huge role to play in this expansion. There's a Chrome extension for anything and everything in this world and what's great is that it's remarkably easy to build one by yourself.

Ansible is an open-source software provisioning, configuration management and an application-deployment tool for enabling infrastructure as code. With the help of Ansible almost any kind of task can be carried out on any number of hosts with the help of commands run on one single master host.

1. What is the role of JVM? JVM is short for Java Virtual Machine. It provides a runtime environment for Java code to run in. It makes sure that Java is compiled once and runs everywhere regardless of operating systems and processors. 2. How is the compilation process of Java source code?

In 2014, Kubernetes surfaced from work at Google and quickly became the de facto standard for container management and orchestration. Despite its silicon valley origins, it became one of the most impactful open-source projects in the history of computing. Today, the Cloud Native Computing Foundation (CNCF) maintains Kubernetes with many private companies and independent open-source developers.

By Romain Huet, Senior Data Scientist at TMC. With more digital data entering the world every day, the first jobs were the ones of data scientists. Today there are so much data that not only Artificial Intelligence is growing, but it is also getting smarter each day.

GitHub is one of the most popular version control systems. Many developers use it to track changes during their projects - regardless of whether the project is being done independently or within a team. Developers seldom gloat about their ability to write meaningful commit messages, but it's a very important skill all developers must learn.

The technology industry innovates quickly, requiring developers to deliver products and services at a rapid speed while still prioritizing high quality. Integration and delivery used to be a manual process, but automation makes it much faster and more reliable. In this article, we'll explore continuous integration and continuous delivery or deployment.

Back in 2010, Amazon migrated its servers to the AWS cloud and launched the Apollo code deployment platform. It allowed developers to deploy code whenever they needed to any of the Amazon servers. So, they also put operations staff to work closer with developers and ensure stable deployment.

Only the open-source Teleport Access Plane consolidates connectivity, authentication, authorization, and audit into a single platform to improve security & agility.

An Application Programming Interface (API) is a set of protocols that allow software components to interact. The intermediary interface is commonly used for streamlining development by enabling software teams to reuse code. APIs also abstract functionality between systems by decoupling applications from the infrastructure they run on.
