Kubernetes projects & tutorial

Welcome to the Kubernetes repository by Coding4Deep. This collection showcases various Kubernetes configurations, deployments, and best practices aimed at simplifying container orchestration and enhancing cloud-native application management.

🚀 Overview

This repository serves as a practical resource for developers and DevOps enthusiasts looking to:

• Understand Kubernetes concepts through hands-on examples.
• Deploy and manage applications using Kubernetes resources.
• Implement persistent storage solutions like NFS provisioners.
• Scale applications efficiently within a Kubernetes cluster.

🛠️ Technologies Used

• Kubernetes: Container orchestration platform for automating application deployment, scaling, and management.
• YAML: Markup language used for configuration files.
• Docker: Platform for developing, shipping, and running applications in containers.
• NFS: Network File System for providing shared storage solutions.

📚 Getting Started

To get started with the projects in this repository:

1. Clone the repository:

   git clone https://github.com/Coding4Deep/kubernetes.git
   cd kubernetes

2. Navigate to the desired directory (e.g., volumes/) and apply the Kubernetes configurations:

   kubectl apply -f .

3. Follow the specific instructions in each directory's README file for detailed setup and usage.

🔍 Usage Examples

Deploying a MongoDB StatefulSet with Persistent Storage

1. Navigate to the volumes/ directory:

   cd volumes/

2. Apply the StatefulSet and service configurations:

   kubectl apply -f mongo-statefulset.yaml
   kubectl apply -f mongo-service.yaml

3. Verify the deployment:

   kubectl get pods -l app=mongo
   kubectl get pvc

4. Access the MongoDB shell:

   kubectl exec -it mongo-set-0 -- mongo

Setting Up an NFS Provisioner

1. Navigate to the volumes/ directory:

   cd volumes/

2. Apply the NFS provisioner configurations:

   kubectl apply -f nfs-provisioner.yaml

3. Verify the deployment:

   kubectl get pods -l app=nfs-provisioner
   kubectl get storageclass

4. Create a PersistentVolumeClaim using the NFS provisioner:

   kubectl apply -f pvc-nfs.yaml

📄 Documentation

For detailed instructions and explanations, refer to the following documents:

• NFS Provisioner Setup Guide: Step-by-step instructions for setting up the NFS provisioner in your Kubernetes cluster.
• MongoDB StatefulSet Deployment: Guide on deploying MongoDB using a StatefulSet with persistent storage.

🧹 Cleanup

To remove the deployed resources:

1. Delete the StatefulSet and service:

   kubectl delete -f mongo-statefulset.yaml
   kubectl delete -f mongo-service.yaml

2. Delete the NFS provisioner:

   kubectl delete -f nfs-provisioner.yaml

3. Delete the PersistentVolumeClaim:

   kubectl delete -f pvc-nfs.yaml
