What Is the Boot Process? The boot process is how Linux goes from bare metal (hardware) → running OS. It’s crucial for DevOps, SREs, and sysadmins, especially when debugging startup issues, recovery mode, or cloud VM initialization. @sysxplore ✅

1️⃣ What is Docker? Docker is a containerization platform; it lets you package an app and all its dependencies into a container so it runs the same everywhere (dev, test, prod). Think of a container as a lightweight, isolated mini-VM, but faster and more portable.

NAT (Network Address Translation) is a method that translates private IP addresses (like 192.168.x.x) into a public IP address when traffic goes to the internet, and vice versa when it returns. Credits: @sysxplore

What is Git? Git is a distributed version control system (DVCS); it tracks changes in code and allows multiple people (or systems) to collaborate efficiently. It’s the backbone of modern DevOps, CI/CD, and software collaboration (used by GitHub, GitLab, Bitbucket, etc.)

What Is Bash? ✅ Bash (Bourne Again Shell) is the command-line shell and scripting language used in Linux and macOS. ✅ It allows you to automate tasks, chain commands, and create reusable scripts for DevOps, CI/CD, and server management.

What is IP? IP is the modern replacement for old networking commands like ifconfig, route, and netstat. It’s part of the iproute2 suite; powerful, scriptable, and standard on all modern Linux distros. Credits: @sysxplore

Linux process management = knowing what’s running, controlling it, and keeping the system healthy. 👉 Everything is a process. 👉 Each has a PID, parent, and signals. 👉 You can view, prioritize, pause, or kill them. 👉 Understanding this = mastering system behavior. @sysxplore

Why PersistentVolumes? - Containers are ephemeral; once a Pod dies or moves, its data is lost. - But many apps (like databases, logs, ML pipelines) need data that survives restarts. Kubernetes solves this with PersistentVolumes (PV) and PersistentVolumeClaims (PVC).

🔹 What is CI/CD? CI (Continuous Integration): - Automate building, testing, and validating code each time a developer pushes to a repo. CD (Continuous Delivery / Deployment): - Automatically deploy tested code to staging or production environments.

Protocols are rules and standards that define how data is transmitted across a network. they ensure that computers, regardless of hardware or os, can communicate reliably. think of them as languages that machines agree to speak. shout out to @sysxplore 👏

Linux is all about who can do what with files and directories. Permissions control read, write, execute access. Credits: @sysxplore

Security in CI/CD Pipelines 🔑 Principle: - Your CI/CD pipeline is only as strong as its security. - Security needs to be shifted left (integrated earlier in development) instead of waiting until production. Credits: @devopscube #security #devops

🔹 What is Kubernetes Autoscaling? Autoscaling in Kubernetes means automatically adjusting resources (pods, nodes) to handle varying workloads; scaling up when demand increases, scaling down when demand decreases. #kubernetes

.

🔹 What is Rust? - A systems programming language created by Mozilla. - Focused on safety, speed, and concurrency. - Often described as “C/C++ without the footguns.” #rust #programming #cloud #devops #relearn

Kubernetes Ingress vs Gateway API 🔹 What is Ingress? - Ingress is the traditional way to expose HTTP/HTTPS services in Kubernetes. - It uses Ingress Controllers (like NGINX, Traefik, HAProxy) to route traffic into the cluster. @KodeKloudHQ explains; https://t.co/TOHJJN4I7t

🔹 What is a Namespace? A virtual cluster inside Kubernetes. Think of it as a way to logically group resources (pods, services, deployments) within a physical cluster. Helps organize, isolate, and manage workloads. . Follow for more #infra content.

🔹 What is YAML? Human-readable config format → like JSON but cleaner. Used in K8s, Ansible, Helm, GitHub Actions & more. 🔹 Why YAML matters ✅ Easy to read/write ✅ Declarative (you say what, not how) ✅ Widely adopted across DevOps ✅ Perfect for IaC & GitOps #yaml
