Description

Just like how real world shipping containers revolutionised the way goods are packaged, handled and transported across the globe industry, Docker along with open container ecosystem is transforming the software delivery by brining in the standardisation. Docker offers a way to run isolated processes and also allows one to package an application along with its run time environment using primitives such as dockerfiles. However, when it comes to running docker in a production like environment, with container work loads spanning across more than one nodes, you need a COE ( Container Orchestration Engine). COEs offer clustering and convert your nodes into one super computer, make intelligent decisions as to where to schedule the containers, connect containers running on different nodes by setting up multi host network and offer many other interesting features such as fault tolerance, zero downtime deployments etc.

Kubernetes is the gold standard in the world of container orchestration. It was originally created by Google, based on their experience of building and managing containers at scale ( at Google Scale). However its now driven by Cloud Native Compute Foundation ( CNCF), an open body, which also offers the official certification i.e. "Kubernetes Certified Administrator". Kubernetes comes with mind boggling features, is very reliable, and extremely sophisticated container orchestration engine. It can let you convert your infrastructure into a Container as a Service (Platform), brining in some of the awe inspiring features such as Zero Down Time Deployments, Fault Tolerance, Auto Scaling, Cloud and Storage integrations, which were extremely difficult to implement. And it brings it to the masses with its truly open, lock in free eco system.

With Kubernetes' sophistication however, comes the complexity too. Even though I have been using Kubernetes for more than 2 years now, almost every month, I find something new about kubernetes, something really cool, be it cloud integrations, or the newly introduced RBAC, be it dynamic storage provisioning, or stateful sets, its a fascinating world once you start exploring it. However, you would definitely need a guide once you while you navigate the complex world of Kubernetes, and this course serves just that. its been created in a way that you start learning kubernetes fround grounds up, one small step at a time, feature by feature.

This course brings to you a distilled experience with my knowledge of building and managing infrastructures, experience of helping companies with their devops journey and more than 300 corporate trainings. This is a well researched program and I have tried many variants of applications, with different flows, took feedback, and iterated many times. Thats one of the reasons why it took us more than 4 months to even launch the course in its first form. We have also started incorporating some new and useful techniques including glassboard, mindmaps to explain the concepts better and make things easier. I and my team wants to make this program the best in the world, and are constantly working towards it.

Here is what this course would cover, one step at a time,

Introduction to Kubernetes and the key concepts
Setting up learning Environment
Pods
Replication Controllers and Replica Sets
Deployments
Services
ConfigMaps and Secrets
Persistent Storage

Our next version would include many additional topics including,

Release Strategies
Horizontal Pod Autoscaler
Helm Package Manager
RBAC
Ingress Controllers
CI/CD with Kubernetes

When you sign up for this course now, you are guaranteed to receive these updates, that our promise to you ! We wish you all the best while learning Kubernetes !!

Who this course is for:

Developers who would like to deploy their applications with containers and like to understand how to leverage Kubernetes features
Operations or devops folks who would like to build Container as a Service and/or Operate it
Anyone who would like to understand Kubernetes from grounds up
Anyone who wants to run containers in Production or Production Like Environments
Anyone who wants to appear for Kubernetes Certified Administrator Exam from CNCF

Lab Guide Preview 00:21

Following URL points to the Lab Guide used throughout this course. Its an essential supporting document, which contains step by step instructions, just as you see in the demo videos. Once you go through the demo videos, you could practically perform the tasks using this guide.

Note: You may notice discrepancy between instructions shown in the video lessons vs what you see in the Lab Guide. In such cases, always trust the lab guide as its been updated to support the newer versions of kubernetes, and also has many fixes. You may also find new labs available in the lab guide for which I am planning to create video lessons. Treat the Lab Guide as the ultimate source of truth !
