Student Journey: Zero to DevOps Engineer with Uncodemy

SECTION 01Stage 1: Foundations for a complete beginner

Everyone starting DevOps from zero begins here, and skipping it causes trouble later. The foundations are Linux (the command line, permissions, processes), Git (version control and a basic workflow), networking basics (DNS, ports, HTTP) and a scripting language such as Bash or Python. These are not glamorous, but every later tool assumes them. The goal of this stage is comfort, not mastery.

# A typical first-stage routine
ssh user@your-vm            # connect to a practice server
ls -la /var/log             # explore the filesystem
chmod 600 secret.txt        # understand permissions

git init && git add . && git commit -m "First project"
git checkout -b feature     # branch, change, merge

#!/usr/bin/env bash
# backup.sh — a small, useful automation
set -euo pipefail
SRC="$HOME/project"
DEST="$HOME/backups/project-$(date +%F).tar.gz"
mkdir -p "$HOME/backups"
tar -czf "$DEST" "$SRC"
echo "Backed up $SRC to $DEST"

SECTION 02Stage 2: Core DevOps tools

With foundations in place, the journey moves to the tools DevOps is known for: continuous integration and delivery (CI/CD), containers with Docker, and orchestration with Kubernetes. This is where abstract ideas become visible — a pipeline that tests and builds your code, an app packaged in a container, and that container running and updating on a cluster. Build a small project through each tool.

name: ci
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - run: ./run-tests.sh
      - run: docker build -t sample-app:${{ github.sha }} .

kubectl create deployment sample --image=sample-app:1.0 --replicas=2
kubectl expose deployment sample --port=80
kubectl set image deployment/sample sample-app=sample-app:1.1
kubectl rollout status deployment/sample
kubectl rollout undo deployment/sample

SECTION 03Stage 3: Cloud and infrastructure as code

The next stage puts your tools on real infrastructure. You learn one cloud platform's core services (compute, storage, networking, identity), then describe that infrastructure in code with a tool like Terraform so it is repeatable and reviewable. You also deepen monitoring so you can see and alert on your systems. Protecting the account and controlling cost are part of this stage from day one.

resource "aws_instance" "app" {
  ami           = var.ami_id
  instance_type = "t3.micro"
  tags = { Name = "devops-journey-app", Owner = "student" }
}

variable "ami_id" { type = string }
# terraform init; terraform plan; terraform apply
# terraform destroy  <- clean up to avoid charges

Before any cloud lab:
[ ] MFA on the account
[ ] Billing alert / budget set
[ ] A limited user, not root, for daily work
[ ] One region chosen
[ ] terraform destroy after each session

SECTION 04Stage 4: Job readiness and a capstone

The final stage ties everything together. You build a capstone project that spans the whole pipeline — code, tests, container, deployment to the cloud, infrastructure as code and monitoring — and document it clearly. Then you prepare: a focused resume, a tidy GitHub, and practice explaining your work and answering common questions. This stage turns learning into a job search.

Capstone: Deploy a sample web app the DevOps way
- Code in Git with a clear README
- CI pipeline: test, build image, push
- Infrastructure as code (Terraform) for the environment
- Kubernetes deployment with rolling updates
- Monitoring with metrics and one alert
- Architecture diagram in the repo

Be ready to explain:
- Your capstone end to end
- How you roll back a bad release
- CI vs CD; container vs image
- A time a lab broke and how you fixed it
- How you keep cloud costs under control

- Built an end-to-end DevOps capstone: Git, CI/CD pipeline,
  Docker image, Kubernetes deployment with rolling updates,
  Terraform infrastructure and basic monitoring
- Documented it with a README and architecture diagram

SECTION 05Staying on track over a months-long journey

The journey takes months, so habits matter more than intensity:

• Study consistently — regular short sessions beat occasional long ones.
• Build at every stage — a small project per stage keeps motivation and proof growing.
• Keep everything in Git — your history is your progress record.
• Ask for help early — a mentor or community prevents long stalls.
• Review and roll back — practise undoing changes, not just making them.
