Kubernetes on Praveen Salitra

Container Orchestration with Azure Kubernetes Service

Fri, 06 Mar 2020 00:00:00 +0000

This one-day in-person workshop focused on bringing concepts of Containers and Container Orchestration to the front-end and back-end engineers. During the day, I covered:

Container vs Virtual Machine
Container Fundamentals
Docker and Docker Compose
Docker Volumes
Overview of the Kubernetes Architecture
Azure Kubernetes Service (AKS) Setup using Terraform
Azure Active Directory integration with AKS
kubectl Fundamentals
Ingress Controller Fundamentals and Installation
externaldns installation
SSL certification automation using cert-manager
Kubernetes Persistent Volumes

During the workshop, the 50+ attendees followed the hands-on exercises on deploying a microservice (Spring Boot, Python, and Node) in a containerized fashion on Azure Kubernetes Service and accessing those endpoints using Ingress Controllers. The services were backed by PostgreSQL databases running along with Kubernetes Persistent Volume attached to the Pod.

Securing Kubernetes API Server with RBAC and AWS IAM

Wed, 17 Jul 2019 00:00:00 +0000

In this meetup, I went through an overview of Kubernetes and then demonstrated how to secure Kubernetes cluster installed on AWS infrastructure via kops or EKS.

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?

This meetup was organized by Cloud Collective meetup group and event details are available here.

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?

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

Thu, 18 Oct 2018 00:00:00 +0000

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?

Setup a High-Available Kubernetes Cluster on AWS using kops

Thu, 04 Oct 2018 00:00:00 +0000

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?

Deep Dive into Kubernetes Architecture and Components

Thu, 27 Sep 2018 00:00:00 +0000

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?
