Hi Everyone — I'm Learning DevOps in Public

I'm a Network Engineer with 3+ years of experience transitioning into DevOps & Cloud Engineering. Every day I study, build, and document what I learn — right here on this repo.

No polished tutorials. Just real learning, real mistakes, and real progress.

Daily blogs on Hashnode → Hashnode LinkedIn updates → Linkedin

What I've Learned So Far

Linux & Shell (19 Days)

Covers Linux fundamentals (navigation, permissions, networking, processes, filesystem, systemd) through advanced Bash scripting (variables, conditions, loops, arrays, functions, error handling, text processing, regex, automation, monitoring, and troubleshooting).

Docker (16 Lessons)

Deep dive from why containers exist through images, volumes, networking, Compose, Dockerfiles, internals, security, optimization, registry, logging, BuildKit, rootless Docker, API, and Docker-in-Docker.

Git & GitHub (11 Lessons)

Complete Git workflow from basics through branching, merging, rebasing, conflict resolution, and GitHub collaboration.

Kubernetes (27 Lessons)

Architecture, Pods, ReplicaSets, Deployments, Services, ConfigMaps, Secrets, Storage, Networking, Ingress, Health Checks, Resource Management, Namespaces, StatefulSets, DaemonSets, Jobs, RBAC, Network Policies, Scheduling, Logging, Security, CRDs, and Disaster Recovery.

Helm (22 Lessons)

Chart structure, template engine, values, conditionals, loops, named templates, ConfigMaps/Secrets, multi-environment deployments, dependencies, upgrade/rollback management, hooks, testing, packaging, repositories, OCI support, and library charts.
