Welcome back to the Kubernetes Mastery Series! In this fifth part, we’ll delve into advanced deployment strategies that will help you manage your applications more effectively and maintain high availability. Before we begin, ensure you have your Kubernetes cluster up and running. If you’ve been following along with the series, your KinD cluster should already be set up. Rolling Updates and Blue-Green Deployments 1. Perform a Rolling Update # Update a Deployment with a new image kubectl set image deployment/<deployment-name> <container-name>=<new-image> 2....

Welcome back to the Kubernetes Mastery Series! In this fourth part, we’ll dive into the world of stateful applications and explore how Kubernetes can help you manage them effectively. Before we begin, ensure you have your Kubernetes cluster up and running. If you’ve been following along with the series, your KinD cluster should already be set up. StatefulSets and Persistent Volumes 1. Create a StatefulSet # Create a StatefulSet for a stateful application kubectl apply -f statefulset....

Welcome back to the Kubernetes Mastery Series! In this third part, we’ll delve into the world of Kubernetes resources and how to manage them effectively. Before we begin, ensure you have your Kubernetes cluster up and running. If you’ve been following along with the series, your KinD cluster should already be set up. Pods, Deployments, and Services 1. List Pods # List all pods in the default namespace kubectl get pods # List pods in a specific namespace kubectl get pods -n <namespace> 2....

Welcome back to the Kubernetes Mastery Series! In this second part, we’ll explore how to deploy your first application to the Kubernetes cluster you set up in Part 1. Before we begin, ensure that you have kubectl`` configured to connect to your KinD cluster. You can check this by running kubectl cluster-info``. It should point to your KinD cluster. Let’s start deploying a simple NGINX web server as our first application:...

Welcome to the Kubernetes Mastery Series! In this first part, we’ll set up a Kubernetes cluster using KinD (Kubernetes in Docker). Prerequisites: Docker kubectl KinD # Step 1: Install Docker # Step 2: Install kubectl # Step 3: Install KinD # Step 4: Create a KinD cluster kind create cluster --name my-cluster --config - <<EOF kind: Cluster apiVersion: kind.x-k8s.io/v1alpha4 nodes: - role: control-plane - role: worker - role: worker EOF # Step 5: Set kubectl context kubectl cluster-info --context kind-my-cluster # Step 6: Verify cluster nodes kubectl get nodes Stay tuned for the next part in our Kubernetes Mastery Series: Part 2 - Deploying Your First App

Managing infrastructure across multiple environments such as development, staging, and production can be a daunting task. Terraform, a popular Infrastructure as Code (IaC) tool, offers a powerful feature known as workspaces that can help you efficiently manage and maintain separate environments within a single configuration. In this technical blog post, we’ll explore Terraform workspaces, how they work, and best practices for utilizing them effectively. Understanding Terraform Workspaces Terraform workspaces provide a way to manage distinct instances of the same infrastructure configuration....

When working with large-scale infrastructure deployments, managing the provisioning and orchestration of resources efficiently becomes crucial. Terraform, a widely-used Infrastructure as Code (IaC) tool, offers a feature known as parallelism to accelerate the deployment process. In this blog post, we’ll delve into parallelism in Terraform, how it affects the Directed Acyclic Graph (DAG), and how you can control and optimize its usage. Understanding Parallelism and the DAG Parallelism refers to the ability to execute multiple tasks simultaneously....
