Lesson 1 | 47:42

What is Kubernetes and responsibility of control plane components

We talk about what exactly is Kubernetes. And once we have setup K8s cluster using kind, how we can use Kubeconfig file to talk to that cluster.
Lesson 2 | 59:56

How does Kube API-Server and controller manager work?

How Kubernetes API Server exposes endpoints for all of its resources, how do we talk to the API Server using CURL, and some K8s resources.
Lesson 3 | 40:10

Writing Go (MySQL) API from scratch, containerizing it and deploying it on Kubernetes | Part - 1

In this chapter, we try to write a very simple REST API in Go and MySQL as a database that is going to get and post the books from/into the database.
Lesson 4 | 18:26

Writing Go (MySQL) API from scratch, containerizing it and deploying it on Kubernetes | Part - 2

Continuing the previous chapter, we try to write a very simple REST API in Go and MySQL as a DB that is going to get and post the books from/into the database.
Lesson 5 | 21:31

Writing Go (MySQL) API from scratch, containerizing it and deploying it on Kubernetes | Part - 3

Continuing the previous chapter, we try to write a very simple REST API in Go and MySQL as a DB that is going to get and post the books from/into the database.
Lesson 6 | 51:03

Writing Go (MySQL) API from scratch, containerizing it and deploying it on Kubernetes | Part - 4

In the last part of the chapter, we write a very simple REST API in Go and MySQL as a database that is going to get and post the books from/into the database.
Lesson 7 | 29:55

Labels, Selectors and Annotations for Kubernetes resources

In this chapter, we will talk about what are labels, selectors, and annotations in the case of Kubernetes.
Lesson 8 | 58:45

Kubernetes Services types and Service Discovery

We take a look into what are Kubernetes Services, and once we have created K8s Services, how do we actually access them or discover them from client pods?
Lesson 9 | 22:38

What are Kubectl Plugins?

We take a look into how we can use kubectl plugins to extend standard kubectl utility to support sub commands that are not supported by default.
Lesson 10 | 36:54

Kubectl tips and tricks | getting and editing the resources | logs | jsonpath

In this chapter, we cover some of the kubectl useful tips & tricks if you working with kubectl on day to day basis to talk to your Kubernetes cluster.
Lesson 11 | 14:12

Kubectl explain | kubectl tips and tricks - Part 2

What are the use cases where we can use kubectl's explain sub command to figure the details about a specific field of Kubernetes resource.
Lesson 12 | 33:15

Kubernetes Ingress Resources | Using Ingress resources to expose your application

We explain what are the use cases where we can use kubectl's explain sub command to figure the details about a specific field of K8s resource.
Lesson 13 | 46:49

Kubernetes Network Policy and Examples

We look into what are Kubernetes Network Policy resources and how we can use them to restrict or allow connections between the pods or other entities.
Lesson 14 | 30:29

Kubernetes Taint and Tolerations

In this chapter, we look into what are taints and tolerations in terms of Kubernetes, & understand some use cases and examples.
Lesson 15 | 21:35

Kubernetes Node Selector and Node Affinity

In this chapter, we take a look at what are NodeSelector and NodeAffinity constructs in terms of Kubernetes.
Lesson 16 | 23:19

Kubernetes initContainers | Wait for MySQL to be running using initContainers

What are initContainers and why do we use them? We modify our library application to run an initContiner that would run some dummy records in the database.
Lesson 17 | 29:51

ImagePullSecrets | Running container image from Private Container Registry

In this chapter, we look into how we can run an application where the application's container image is pushed into a private repository/registry.
Lesson 18 | 48:51

Kubernetes Volumes and Persistent Volumes

We talk about Kubernetes' ephemeral and persistent volumes, how do we provision them and how are they bound to a specific volume claim or request.
Lesson 19 | 32:18

Kubernetes CRDs (Custom Resource Definitions) and CRs (Custom Resources) explained, with examples

We talk about what are Kubernetes Custom Resources and how we can create or register them with API Server using Custom Resource Definition.
Lesson 20 | 37:17

Deployment vs StatefulSet Kubernetes

In this chapter, we will look into the difference between Deployment or StatefulSet Kubernetes resources.
Lesson 21 | 23:08

Kubernetes Controllers, Custom Controllers and Operators explained with use cases

What exactly are K8s controllers, Custom Controllers & Operators? We start with controllers that run as part of Controller manger & define a custom controller.
Lesson 22 | 33:08

Kubernetes ConfigMap and Secrets resources, examples, types and how to use them in Pod

What are K8s & Secrets resources? We discuss the ways in which a ConfigMap can be used inside a Pod, e.g. as environment variable, volume or in commands.
Lesson 23 | 35:33

Kubernetes Service Account

What are Kubernetes Service Account resources, how do we can use them in the processes (programs) that are running in K8s, to access Kubernetes API-Server.
Lesson 24 | 38:50

Role Based Access Control (RBAC) in Kubernetes

In this chapter, we will look into Role Based Access Control (RBAC) or authorisation in Kubernetes. We will discuss some scenarios. Let's dive in.
