Getting Started with Docker

JavaScript Tutorial — Fri, 17 Jan 2020 07:30:08 +0000

Docker is everywhere but maybe you aren't quite up to speed yet. You can talk about it or at least fake your way through a conversation but you haven't had time to get started actually using it yet. If that sounds like you, this is your session. We will walk through Docker from the beginning. Don't be fooled though. This isn't a PowerPoint session. We won't be doing fun pictures and abstract concepts. We will be taking code and putting it into containers. Then we will look at how to use those containers, how to communicate with them, how to manage them, and more. After we cover the basics, we will get into orchestration and other more complicated topics. While this is a language-agnostic talk, we will use the Visual Studio tools for some sites and situations.

IntelliJ IDEA for Beginners - Learn IntelliJ IDEA from Scratch

JavaScript Tutorial — Mon, 06 Jan 2020 04:07:46 +0000

Complete IntelliJ IDEA Course for Beginners

IntelliJ IDEA for Beginners - Learn IntelliJ IDEA from Scratch

How to become an expert IntelliJ IDEA Developer

This course takes is specifically designed for developers that either don't have any previous experience using an Integrated Development Environment (IDE) tool or experienced IDE developers new to Intellij IDEA (e.g. experienced Eclipse developers).

With that said, even if you're an experienced Intellij IDEA developer you might still get something out of the course. This is specially true since this course is (almost exclusively) based on version 2019 which introduced features that you may not yet me familiar with. So please still check it out!

Also, no particular programming language knowledge is assumed since Intellij IDEA is pretty much language agnostic and supports many different programming languages.

Sections I, II and III are mandatory and must be taken in order.

Section IV is specifically designed for experienced Eclipse developers interested in a quick migration path to IntelliJ

The rest of the sections (V, VI, VII and VIII) can be taken in any order as they're self contained. I highly recommend that you still taken them all, particularly if you don't have any previous Intellij IDEA experience.

Learn HTML5 and CSS3 for Beginners

JavaScript Tutorial — Thu, 02 Jan 2020 06:57:16 +0000

Learn HTML5 and CSS3

All HTML and CSS Elements are explained in easiest ways.

HTML and CSS are the basic programming languages for web development and design. They are beneficial to learn for developers, marketers, and people in many other disciplines. Learning HTML can be used for situations like formatting a blog or email, working with a CMS, embedding external content on your site, and creating usable content.

Cascading Style Sheets or CSS are an important way to control how your Web pages look. CSS can control the fonts, text, colors, backgrounds, margins, and layout. But it can be very difficult to learn CSS, and some people would rather not learn it.

By learning CSS you can modify pre-built templates so that they have your colors and styles. Thus you'll have a customized website without a lot of effort.

Knowing how to modify the CSS will save you money when you find small problems that you can fix yourself. And as you practice, you'll be able to fix bigger and bigger problems.

CSS gives you the opportunity to create sites that look very different from page to page, without a lot of extensive coding.

This course going to cover:

HTML Basic Tags.
CSS - Selectors.
CSS - Units & Color codes.
CSS - Margin, Padding and Border.
CSS - Display, Box-sizing & Positioning.
CSS - Font Styling.
CSS - Flexbox.
CSS - Grid.
CSS - Background Properties.
CSS - Gradients.
CSS - Transform, Transitions and Animations.
Bonus - SASS.

The best free Kubernetes courses for Beginners

JavaScript Tutorial — Sat, 28 Dec 2019 16:03:54 +0000

Kubernetes (commonly stylized as k8s) is an open-source container-orchestration system for automating application deployment, scaling, and management. It was originally designed by Google, and is now maintained by the Cloud Native Computing Foundation. It aims to provide a "platform for automating deployment, scaling, and operations of application containers across clusters of hosts". It works with a range of container tools, including Docker. Many cloud services offer a Kubernetes-based platform or infrastructure as a service (PaaS or IaaS) on which Kubernetes can be deployed as a platform-providing service. Many vendors also provide their own branded Kubernetes distributions.

More and more people realize the importance of Kubernetes and learning tools like Jenkins, Docker and and if you are in the same boat, these free courses will provide you with great knowledge. to jump into the Kubernetes world

Free Courses to Learn Kubernetes for Developers

Even though these courses are free but they are nice courses and just made free by their instructor for promotional and educational purposes.

If you are starting with Kubernetes, I suggest you join one of these courses to get a feel of what is Kubernetes.

1. Introduction to Kubernetes

In this course, we'll discuss some of Kubernetes' basic concepts and talk about the architecture of the system, the problems it solves, and the model that it uses to handle containerized deployments and scaling.

This course offers an introduction to Kubernetes and includes technical instructions on how to deploy a stand-alone and multi-tier application. You’ll learn about ConfigMaps and Secrets, and how to use Ingress.

Upon completion, developers will have a solid understanding of the origin, architecture and building blocks for Kubernetes, and will be able to begin testing the new cloud native pattern to begin the cloud native journey.

2. Learn DevOps Kubernetes deployment by kops and terraform

This is another practical course to learn Kubernetes on AWS by using kops and Terraform. In this course, you will learn how to deploy a Kubernetes cluster in AWS and how to use Terraform to run an immutable infrastructure.

You will also learn about the horizontally scaled deployment in Kubernetes and how to use Kops to spin up the Kubernetes cluster.

Most importantly, you will learn how to see logs, get inside the Docker container within the pod in Kubernetes.

3. Just enough kubernetes to be dangerous

This course would serves as the first step in your kubernetes journey. It would help you get started with Kubernetes quickly and build a foundation while learning by practicing it. This is a really nice course to learn Kubernetes in a short time.

You will not only set up kubernetes cluster with Google Kubernetes Engine but also learn how to deploy a micro-services application and publish it to the world.

You will also learn how to dynamically scale your application using the auto-scaling feature of kubernetes, and release application updates without any downtime, or, achieve Zero downtime deployments.

4. Getting Started with Kubernetes

This course will teach you the theory and practical skills required to get you up and running as fast as possible.

The course can be logically divided into three parts. In the first part, you'll dive into Kubernetes architecture, what the main components and services are, and how they come together to build a production-class container infrastructure.

In the second and third part, you'll learn how to install and deploy Kubernetes on several cloud platforms and learn to work with pods, deployments, and services.

By the end of this course, you'll have a solid understanding of what Kubernetes is and how it works, as well as skills to deploy a Kubernetes cluster and simple applications.

5. Containers 101

In this course, introduce the basics of building and deploying packaged applications. You will learn the concepts of containers provided by Docker and how to create them. You will learn the essentials for modern DevOps with the arrangement, packaging and many other things built on the fast growing Docker, Kubernetes and Helm.

That's all about some of the free courses to learn Kubernetes in 2020. As I have said, Kubernetes is one of the most important container management technology and really important if you are thinking about DevOps in Cloud. I suggest you to spend some time learning various tools and features offered by Kubernetes for scaling your containers, including the auto-scaling feature of Kubernetes.
