Kubernetes Cluster Election

💡 Choosing the Right K8s Environment for Your Needs

K8s offers various technologies tailored to different tasks, each with its own characteristics and advantages.

Some popular options:

1️⃣ Minikube (https://lnkd.in/ePQKyEZ7)

> Compatible with Linux, Windows, and macOS
> Uses virtualization to deploy a cluster on a Linux virtual machine
> Suitable for Linux without virtualization support

2️⃣ Kubeadm (https://lnkd.in/epyumfKZ)

> The official CNCF tool for provisioning Kubernetes clusters
> Offers flexibility for various cluster configurations (single node, multi-node, HA, self-hosted, etc.)
> Ideal for launching minimal viable Kubernetes clusters

3️⃣ Kops (Kubernetes Operations) (https://lnkd.in/e7ApRVJP)

> Provides tools for installing, operating, and removing Kubernetes clusters on cloud platforms like AWS, Google Cloud Platform, OpenStack, and DigitalOcean

4️⃣ Microk8s (https://microk8s.io)

> Similar to Minikube, it creates single-node clusters
> Features its own set of add-ons as configuration plugins
> Exclusive to Linux environments

5️⃣ K3s (https://k3s.io)

> Works on any Linux distribution without external dependencies
> Replaces Docker with containerd as the container runtime and uses sqlite3 as the default database
> Lightweight, consuming only 512MB of RAM and 200MB of disk space.

6️⃣ Kind (Kubernetes-in-Docker) (https://kind.sigs.k8s.io)

> Runs Kubernetes clusters in Docker containers
> Supports multi-node and High-Availability clusters
> Compatible with Windows, Mac, and Linux as it runs on top of Docker

7️⃣ K3d (https://k3d.io)

> A project aiming to dockerize K3s

The choice of the Kubernetes environment depends on your project's specific needs.

Once you understand K8s basics, the next step is to create a cluster, which can be done both locally and in the cloud.

Traffic control in the digital world can feel like solving a complex puzzle.
✅API Gateway, Load Balancer, Reverse Proxy—they all seem to do the same thing at first glance. But the truth? Their purposes are unique, and understanding them can transform your architecture. Let's unravel the mystery!

📷 𝐑𝐞𝐯𝐞𝐫𝐬𝐞 𝐏𝐫𝐨𝐱𝐲: 𝐓𝐡𝐞 𝐆𝐚𝐭𝐞𝐤𝐞𝐞𝐩𝐞𝐫
A reverse proxy sits in front of your servers, handling client requests. Think of it as a middleman.

𝐊𝐞𝐲 𝐅𝐞𝐚𝐭𝐮𝐫𝐞𝐬:
✅ Improves security by hiding internal server details.
✅ Enables caching for faster responses.
✅ Simplifies SSL termination and encryption.
When to Use It:
- You need to protect your backend infrastructure from direct exposure.
- You’re managing HTTP/HTTPS traffic effectively.

⌛ 𝐋𝐨𝐚𝐝 𝐁𝐚𝐥𝐚𝐧𝐜𝐞𝐫: 𝐓𝐡𝐞 𝐓𝐫𝐚𝐟𝐟𝐢𝐜 𝐌𝐚𝐧𝐚𝐠𝐞𝐫
A load balancer ensures requests are spread across multiple servers to prevent overload. It's like directing traffic during rush hour.
Key Features:
✅ Ensures high availability by distributing workloads.
✅ Provides failover to handle server outages.
✅ Supports scalability by managing increased traffic.
When to Use It:
- You have multiple servers and need to maintain consistent performance.
- Uptime and reliability are your top priorities.

🔗 𝐀𝐏𝐈 𝐆𝐚𝐭𝐞𝐰𝐚𝐲: 𝐓𝐡𝐞 𝐀𝐏𝐈 𝐒𝐩𝐞𝐜𝐢𝐚𝐥𝐢𝐬𝐭
API Gateway acts as the single entry point for APIs, handling all the heavy lifting. It’s the concierge for your microservices.
Key Features:
✅ Handles authentication, rate limiting, and logging.
✅ Simplifies API versioning and routing.
✅ Bridges communication between microservices.
When to Use It:
- You’re managing multiple APIs and need centralized control.
- You want to offload cross-cutting concerns like security or monitoring.

🧩 𝐇𝐨𝐰 𝐭𝐨 𝐂𝐡𝐨𝐨𝐬𝐞?
- Use Reverse Proxy if you need enhanced security and basic traffic forwarding.
- Use Load Balancer to distribute traffic and ensure availability.
- Use API Gateway for a powerful, API-first architecture, especially with microservices.

🐱 Git can be confusing at first. But trust me, once you grasp the basics, it's a game-changer.

▶️ Here's a quick rundown:

⚡️𝐘𝐨𝐮𝐫 𝐖𝐨𝐫𝐤𝐬𝐩𝐚𝐜𝐞: This is where you actually code. Simple.

⚡️𝐒𝐭𝐚𝐠𝐢𝐧𝐠 (𝐠𝐢𝐭 𝐚𝐝𝐝): Think of it as a prep area. You're telling Git, "Hey, these changes are important."

⚡️𝐋𝐨𝐜𝐚𝐥 𝐑𝐞𝐩𝐨 (𝐠𝐢𝐭 𝐜𝐨𝐦𝐦𝐢𝐭): This is your personal save point. Commit often, thank yourself later.

⚡️𝐑𝐞𝐦𝐨𝐭𝐞 𝐑𝐞𝐩𝐨 (𝐆𝐢𝐭𝐇𝐮𝐛, 𝐆𝐢𝐭𝐋𝐚𝐛 𝐞𝐭𝐜.): The cloud where your team's code lives. This is where the collaboration magic happens.

⚡️𝐊𝐞𝐲 𝐦𝐨𝐯𝐞𝐬:
- 𝑷𝒖𝒔𝒉: Send your local commits to the remote repo.
- 𝑷𝒖𝒍𝒍: Grab the latest changes from remote. It's actually fetch + merge in one go.
- 𝑭𝒆𝒕𝒄𝒉: Download changes, but don't apply them yet.
- 𝑴𝒆𝒓𝒈𝒆: Combine those fetched changes with your work.

▶️ What are Static Pods in K8S? How do they work?


🔖 Static pods are special Kubernetes pods managed directly by the Kubelet rather than the Kubernetes control plane. They are primarily used for managing critical components of the Kubernetes system, especially in self-hosted clusters or during cluster bootstrapping.

The working of static pods can be explained with the help of steps below:

1️⃣. Static Pods are defined in manifest files (𝐘𝐀𝐌𝐋 𝐨𝐫 𝐉𝐒𝐎𝐍).

2️⃣. These manifest files are placed in a specific directory on a node (e.g., /𝐞𝐭𝐜/𝐤𝐮𝐛𝐞𝐫𝐧𝐞𝐭𝐞𝐬/𝐦𝐚𝐧𝐢𝐟𝐞𝐬𝐭𝐬).

🔤. The 𝐤𝐮𝐛𝐞𝐥𝐞𝐭 on the node monitors this directory for changes.

4️⃣. When a manifest file is 𝐚𝐝𝐝𝐞𝐝, 𝐮𝐩𝐝𝐚𝐭𝐞𝐝, 𝐨𝐫 𝐫𝐞𝐦𝐨𝐯𝐞𝐝, 𝐭𝐡𝐞 𝐤𝐮𝐛𝐞𝐥𝐞𝐭 𝐜𝐫𝐞𝐚𝐭𝐞𝐬, 𝐮𝐩𝐝𝐚𝐭𝐞𝐬, 𝐨𝐫 𝐝𝐞𝐥𝐞𝐭𝐞𝐬 corresponding static pod.

Static pods are not created through the Kubernetes API server, so they do not have the full capabilities of API-managed pods. However, the kubelet creates a 𝐦𝐢𝐫𝐫𝐨𝐫 𝐩𝐨𝐝 in the API server for visibility, allowing tools like 𝐤𝐮𝐛𝐞𝐜𝐭𝐥 to display their status.

➡️ How do companies ship code to production?

The diagram above illustrates the typical workflow.

➡️Step 1: The process starts with a product owner creating user stories based on requirements.

➡️Step 2: The dev team picks up the user stories from the backlog and puts them into a sprint for a two-week dev cycle.

➡️Step 3: The developers commit source code into the code repository Git.

➡️Step 4: A build is triggered in Jenkins. The source code must pass unit tests, code coverage threshold, and gates in SonarQube.

➡️Step 5: Once the build is successful, the build is stored in artifactory. Then the build is deployed into the dev environment.

➡️Step 6: There might be multiple dev teams working on different features. The features need to be tested independently, so they are deployed to QA1 and QA2.

➡️Step 7: The QA team picks up the new QA environments and performs QA testing, regression testing, and performance testing.

➡️Steps 8: Once the QA builds pass the QA team’s verification, they are deployed to the UAT environment.

➡️Step 9: If the UAT testing is successful, the builds become release candidates and will be deployed to the production environment on schedule.

➡️Step 10: SRE (Site Reliability Engineering) team is responsible for prod monitoring.
