🏔 Understanding Kubernetes Primitives

Hello engineers, I hope you're having a great day! Here is part two of our Kubernetes recipes. Grab your coffee ☕️ and enjoy:

Resources:

⚛️ Ingress: Manages external access to services within the cluster, enabling routing based on hostnames and paths.

⚛️ NetworkPolicy: Defines communication rules between groups of pods and network endpoints.

⚛️ HorizontalPodAutoscaler: Automatically adjusts the number of pod replicas based on resource utilization metrics.

⚛️ Job: Executes tasks until completion, often used for batch processing.

⚛️ CronJob: Schedules jobs to run at specified intervals using cron notation.

⚛️ ResourceQuota: Enforces constraints on resource consumption within a namespace.

⚛️ LimitRange: Defines resource limits and ranges for compute resources.

Infrastructure Components

⚛️ Kubelet: The primary node agent, responsible for the execution and management of containers on each node.

⚛️ Kube-proxy: The network proxy that facilitates the exposure of Kubernetes networking services on individual nodes.

⚛️ Container Runtime: The underlying software responsible for executing containers, which could be docker, containerd, or a compatible runtime.

⚛️ CNI Plugins: Container Network Interface plugins that configure network interfaces within pods to enable network communication.

⚛️ Node: Worker unit in a Kubernetes cluster, responsible for running containerized applications within pods. Think of node as the machineries or the base engines. 🚂

✅ Project Title: Deploy a 3 Tier Architecture On AWS - End to End Project

Project Overview:
✅ Tier 1: Presentation Layer
☑ Create a web application using a framework like React, Angular, or Vue.js.
☑ Host the frontend on Amazon S3 or use AWS Amplify for a serverless frontend deployment.

✅ Tier 2: Application Layer
☑ Develop a server-side application using a technology like Node.js, Python, or Java.
☑ Deploy the application on AWS Elastic Beanstalk or AWS Lambda for serverless applications.
☑ Use Amazon API Gateway for creating RESTful APIs or AWS App Runner for containerized applications.

✅ Tier 3: Data Layer
☑ Choose a database solution like Amazon RDS (Relational Database Service), Amazon DynamoDB (NoSQL), or Amazon Aurora (MySQL/PostgreSQL).
☑ Configure database security groups and access controls.
☑ Ensure data backup and redundancy as per your application's needs.

How to Learn Kubernetes 🚀

In this Kubernetes learning roadmap,

I have added prerequisites and complete Kubernetes learning path covering basic to advanced Kubernetes concepts.

Learning Kubernetes can seem overwhelming. It’s a complex container orchestration system, that has a steep learning curve.

But with the right roadmap and understanding of the foundational concepts, it’s something that any developer or ops person can learn.

AWS Billing Alert Terraform Module

📢 Excited to share my latest open-source contribution - The AWS Billing Alert Terraform Module!

Link: https://github.com/NotHarshhaa/aws-billing-alert-terraform.git

Navigating AWS costs can sometimes be tricky. To aid users in proactive cost management, I've developed a Terraform module that automates the setup of billing alerts. With this tool, you'll receive timely notifications if your AWS charges cross predefined thresholds.

📊 Integrated with AWS #CloudWatch - Monitor your #billing metrics seamlessly.

🔔 Leverages AWS #SNS - Get instant notifications so you can act swiftly.
For those keen on ensuring their AWS expenses stay within predictable boundaries, this tool is a valuable asset for every AWS Engineer.

Linux's file system is tree-like. The base is "/", with everything else branching off.

Core Directories:

/bin 🛠: Essential binaries, e.g., bash, ls, grep.
/boot 🚀: Boot items like kernel & bootloader.
/dev 🔌: Device files for connected hardware.
/etc 📜: System configuration files.
/home 🏠: User home directories.
/lib 📚: Shared libraries for programs.
/media 💿: Mounts for removable media.
/mnt 🧲: Temporary mounts.
/opt 📦: Optional software.
/proc 📊: System, process, memory info.
/root 👑: Root user's home.
/sbin 🔧: System admin tools, e.g., init.
/srv 🌐: Data for services.
/tmp 🌡: Temporary files.
/usr 🖥: User software.
/var 🔄: Variable data, logs, temp files.

Linux Commands:

cd 🚶: Navigate.
ls 📋: List contents.
mkdir 📁: Create folder.
rmdir 🗑: Delete folder.
cp 📤: Copy.
mv 🚚: Move.
rm ❌: Delete.

⚠️ Note: Directories like /bin are crucial. Don't modify!
