Kubernetes Masterclass - Fall 2018

Workshop ·

A series of 7 online sessions focusing on overview of Kubernetes fundamentals, architecture, kops, stateless and stateful workloads, ingress, SSL certificates, and disaster recovery.

1. Deep Dive into Kubernetes Architecture and Components⌗

In this session, I went through an overview of containers and understood how Kubernetes has become Gold Standard in container orchestration frameworks.

I answered questions like:

  • What is a container?
  • Why you should use containers?
  • What infrastructure do you need to run containers?
  • How Kubernetes (aka k8s) fits into the world of containers?
  • What are the components that make a Kubernetes cluster?
  • How Kubernetes orchestrates containers?
  • Who are the competitors of Kubernetes?

2. Setup a High-Available Kubernetes Cluster on AWS using kops⌗

In this session, I talked about how to setup Kubernetes on the local machine. And then went through the complex production-ready setup of Kubernetes on AWS infrastructure.

I answered questions like:

  • How to setup Kubernetes on the local machine?
  • What components are required to be installed when setting up Kubernetes?
  • How to setup Kubernetes on an AWS cluster using kops?
  • How to make Kubernetes cluster highly available (HA) on AWS?
  • How is kops setup compared to the Amazon’s managed service EKS?
  • What are some important things to keep in mind while working with kops and Kubernetes?

3. Harden Kubernetes Access Security with RBAC and AWS IAM⌗

In this session, I talked about how to secure Kubernetes cluster installed on AWS infrastructure.

I answered questions like:

  • How Kubernetes uses RBAC to secure API access?
  • What are the Kubernetes Service Accounts?
  • How to integrate AWS IAM with Kubernetes Auth Controller via aws-iam-authenticator?
  • How to update your kubeconfig to properly utilize your aws-cli config setup?
  • How to securely access multiple Kubernetes clusters from the same local machine?

4. Deploy Stateless Workload on Kubernetes with Pods, Deployments, Daemonsets, and Services⌗

In this session, I talked about how to deploy stateless workload with Pods, Deployments, DaemonSets, and Services in a Kubernetes cluster installed on AWS infrastructure.

I answered questions like:

  • What is a minimum deployable unit (aka Pod) in Kubernetes?
  • What are Deployment and DaemonSet? How are these related to a Pod?
  • How to set resource quota limits (CPU and Memory) for the Pods and Namespaces?
  • What is a Service? What are different types of Service?
  • What are a few important things to keep in mind while working with the stateless workload on Kubernetes?

5. Deploy Stateful Workload on Kubernetes with Persistent Volumes and StatefulSets⌗

In this session, I talked about how to deploy stateful workload with Persistent Volumes and StatefulSets in a Kubernetes cluster installed on AWS infrastructure.

I answered questions like:

  • What is a container Volume?
  • How Volumes work with Kubernetes?
  • What are different types of Persistent Volumes in Kubernetes?
  • How to provision Persistent Volumes on Kubernetes deployed on AWS?
  • What are StatefulSets and how to configure and use them?
  • What are a few important things to keep in mind while working with the stateful workload on Kubernetes?
