Version control with 🧑‍💻 GIT has become an essential skill for developers.

In this post, I'll provide a quick overview of some core GIT concepts and commands.

Key concepts:
➡️ Repository - Where your project files and commit history are stored
➡️ Commit - A snapshot of changes, like a version checkpoint
➡️ Branch - A timeline of commits that lets you work on parallel versions
➡️ Merge - To combine changes from separate branches
➡️ Pull request - Propose & review changes before merging branches

Key commands:
➡️ git init - Initialize a new repo
➡️ git status - View changed files not staged for commit
➡️ git add - Stage files for commit
➡️ git commit - Commit staged snapshot
➡️ git branch - List, create, or delete branches
➡️ git checkout - Switch between branches
➡️ git merge - Join two development histories (branches)
➡️ git push/pull - Send/receive commits to remote repo

➡️ As a software professional, keeping up with the latest DevOps tools is essential for optimizing development and delivery.

The right tools make teams more productive, applications more resilient, and organizations more innovative.

Here are some of the most impactful DevOps tools I recommend learning in 🌟🌟:

✍️ Kubernetes: This open-source container orchestration system simplifies deploying and managing containerized applications. It allows scaling and balancing container workloads.

✍️ Terraform: Infrastructure as code is a must today. Terraform lets you define cloud and on-prem infrastructure in files and provision it automatically.

✍️ Docker: Containerizing apps with Docker packages software into standardized units along with dependencies to run anywhere consistently. It accelerates development.

✍️ Ansible: This configuration management and automation tool executes tasks across nodes via SSH without needing agents. It's simple yet powerful.

✍️ Prometheus: A top open-source monitoring and alerting solution that scrapes metrics and provides robust query capabilities with PromQL.

✍️ Grafana: The leading analytics and visualization platform for monitoring. It’s easy to create rich dashboards for operational insights.

✍️ ELK Stack: Combines Elasticsearch, Logstash, and Kibana for centralized logging, searching, and visualizing log data for troubleshooting.

I aim to provide actionable insights on leading tools so you can advance your skills efficiently.

Kubernetes: You need to know this 👇

When you do a port farward to a nginx service,

you happily create a tunnel to a single pod 😚

kubectl port-forward svc/nginx 8080:80

❌ Now. Here's a problem:

1. Wonder what happens if the traffic serving pod is terminated?
2. The browser returns "refused to connect" error.

Why?

Because the tunnel is broken.

✔️ To re-establish connection:

"You need to run port-forward command again."
"Port forwarding is useful for testing only."
"For production use cases, always use deployments"

Hope you happily learned something 😎

🔴 Architecture of a Kubernetes Cluster ☸️

A production-ready Kubernetes cluster is vastly complex. There are many non-negotiable such as High Availability, Fault Tolerance, data backups and durability requirements.

Its architecture is divided into the Control Plane and Data Plane.
This is what they do 👇

➡️ DATA PLANE
The part of the cluster where all compute resources reside. This is where ultimately all your container applications run.

1️⃣Nodes
The worker machines that actually run container workloads. These could be EC2 servers (or other cloud provider equivalents), bare-metal servers or even just your personal computer.

2️⃣Pods
The smallest unit of compute that you can deploy in K8s. A Pod contains 1 or more containers running your application(s) and helper processes. A Pod runs inside a Node.

3️⃣Kubelet
An agent that runs on every Node. It takes Pod specifications provided by the user and ensures that the Containers described in them are running and healthy.

4️⃣Kube-proxy
Runs on every Node and manages network rules on the system to ensure network communication works smoothly between Pods and the outside world.

5️⃣Container Runtime
Runs on all nodes and manages the lifecycle of container(s) deployed on them. Eg- Docker, CRI-O, etc.

➡️ CONTROL PLANE
Does the administrative tasks of managing worker nodes, Pods and the cluster in general.
It is basically the “brains” of the cluster that makes all decisions like scheduling, always steering the cluster towards the desired state (eg- spin up new pods in response to some pods going down to maintain the desired number of them).

🔢Kube-apiserver
Exposes the Kubernetes API to the user. When you make an API request to Kubernetes or use a client like Kubectl, you request is handled by kube-apiserver and passed on for further processing.

🔢Etcd
A consistent and highly available Key-value store used by Kubernetes for storing all cluster data. You should have a strong backup strategy for this datastore as it tracks all state of the cluster.

🔢Scheduler
Responsible for placing Pods on to Nodes in the most optimal way possible. When a new Pod is requested, the scheduler looks for a suitable Node to run it in.
Takes many different factors into consideration while scheduling, such as resource requirements, priority, user-specified criteria, etc.

🔢Controller Manager
Runs Controllers. A Controller is a process that always steers the system toward a desired state. Eg- A Node controller monitors and responds when nodes go down.
