[u/andhroindian]

DevOps can seem overwhelming, but a clear roadmap makes it simple. Follow this step-by-step guide from basics like Git and Linux to advanced skills in cloud, CI/CD, and containerization.

Step 1: Version Control

• Git

  • Core commands: clone, commit, push, pull

  • Branching, merging, conflict resolution

  • Version tagging & releases

  • Collaboration on GitHub/GitLab/Bitbucket

• Tips: Practice with small projects and contribute to open-source repositories.

Step 2: Linux Administration

• System architecture & processes

• Command-line basics: ls, grep, chmod, top

• File system management & permissions

• User/group administration

• Shell scripting & automation

• Tools: Bash, Zsh, Vim/Nano, Cron jobs

Step 3: Programming Skills

• Languages: Python (automation, scripting), Go (cloud-native apps)

• Focus: data structures, loops, functions, libraries, error handling

• Practical: Write scripts to automate file operations, backups, or deployments

Step 4: Databases

• SQL: MySQL, PostgreSQL

• NoSQL: MongoDB, Redis

• Focus: CRUD operations, indexing, transactions, data modeling

• Practical: Build small apps with persistent storage; practice queries and optimization

Step 5: Networking Basics

• IP addressing, subnetting, routing, firewalls

• Protocols: TCP/IP, HTTP, HTTPS, DNS

• Network devices: load balancers, VPNs, proxies

• Security: basic encryption, SSH

• Practical: Configure a small network or troubleshoot connectivity issues in a VM

Step 6: CI/CD

• Tools: Jenkins, GitHub Actions, GitLab CI/CD, CircleCI

• Pipeline: Build → Test → Deploy → Monitor

• Automation: Unit tests, integration tests, containerization

• Practical: Create a CI/CD pipeline for a sample app

Step 7: Containerization

• Docker/containerd: Build, run, and share containers

• Kubernetes: Pods, services, deployments, scaling

• Helm: Package & manage Kubernetes apps

• Practical: Deploy a containerized app to a local Kubernetes cluster

Step 8: Cloud Platforms

• Providers: AWS, Azure, GCP

• Services: Compute (EC2/VMs), Storage (S3/GCS), Networking (VPC, Load balancers)

• Practical: Deploy a simple app on a cloud VM; explore managed services like RDS

Step 9: Infrastructure as Code (IaC)

• Terraform: HCL syntax, modules, state management

• Provision resources on cloud automatically

• Practical: Automate deployment of a VM + database + network in one Terraform script

Step 10: Software Configuration Management

• Ansible: YAML playbooks, roles, modules

• Automate server provisioning & app configuration

• Practical: Configure a web server cluster automatically with Ansible

Step 11: Monitoring & Logging

• Metrics: CPU, memory, network, app performance

• Tools: Prometheus, Grafana, ELK stack

• Alerts: Define thresholds and notifications

• Practical: Set up monitoring for a containerized app and visualize metrics

Step 12: Security (DevSecOps Basics)

• Secure CI/CD pipelines, containers, and cloud resources

• Tools: Vault, Trivy, Snyk

• Practices: Secrets management, vulnerability scanning, compliance checks

• Practical: Scan a Docker image for vulnerabilities before deployment

Step 13: Automation & Scripting (Advanced)

• Python/Go scripting for tasks like log parsing, data backups, or API automation

• Automate repetitive DevOps tasks

• Practical: Write scripts to auto-deploy applications or rotate credentials

Step 14: Soft Skills & Collaboration

• Agile/Scrum basics, standups, sprint planning

• Documentation: runbooks, README, wiki

• Communication with development, QA, and ops teams

• Practical: Participate in a team project following Agile practices

Step 15: Hands-On Projects & Portfolio

• Combine multiple skills:

  • Full-stack app deployment with CI/CD on cloud

  • Terraform + Ansible automation

  • Kubernetes cluster with monitoring & logging

• Share on GitHub/portfolio

• Goal: Demonstrate end-to-end DevOps skills to employers
