Congratulations on reaching the final part of the Kubernetes Mastery Series! In this tenth and final installment, let’s recap the key Kubernetes best practices and take a moment to reflect on your Kubernetes journey. Best Practices Recap Cluster Setup Choose a Kubernetes installation method that suits your needs. Secure your cluster with RBAC, network policies, and up-to-date Kubernetes versions. Application Deployment Use Helm for package management and easy application deployments. Employ advanced deployment strategies like rolling updates, blue-green deployments, and canary releases for controlled application changes....

Welcome back to the Kubernetes Mastery Series! In this ninth part, we’ll dive into disaster recovery and backup strategies to ensure the resilience and availability of your Kubernetes applications and data. 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. Disaster Recovery Planning 1. Identify Critical Components Identify the critical components of your Kubernetes cluster and applications, including databases, storage, and configuration data....

Welcome back to the Kubernetes Mastery Series! In this eighth part, we’ll dive into essential security best practices for your Kubernetes cluster. Securing your Kubernetes environment is crucial for protecting your applications and sensitive data. 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. Securing Kubernetes Control Plane 1. Use RBAC (Role-Based Access Control) Create RBAC policies to define who can access and perform actions on resources in your cluster....

Welcome back to the Kubernetes Mastery Series! In this seventh part, we’ll explore essential practices for monitoring and logging in Kubernetes, crucial for maintaining the health and performance of your applications. 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. Monitoring with Prometheus and Grafana 1. Install Prometheus Operator # Install Prometheus Operator using Helm helm repo add stable https://charts....

Welcome back to the Kubernetes Mastery Series! In this sixth part, we’ll dive into Helm, a powerful package manager for Kubernetes that simplifies application deployment and management by providing templating and versioning capabilities. Before we begin, ensure you have Helm installed on your system. If not, you can install it by following the official Helm installation guide. Helm Basics 1. Initialize a Helm Chart # Create a new Helm chart helm create my-chart 2....

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
