Here are the most important questions.</p> <p>Full Q&amp;A + PDF: <a href="https://devopsrise.vercel.app/qa" rel="noopener noreferrer">devopsrise.vercel.app</a></p> <h2> Beginner Questions </h2> <p><strong>Q: What is Terraform?</strong><br> Open-source IaC tool by HashiCorp. Provisions <br> infrastructure using declarative HCL configuration.<br> Supports 1000+ providers (AWS, Azure, GCP, K8s).</p> <p><strong>Q: What is terraform init?</strong><br> Downloads provider plugins, initializes backend,<br> creates .terraform directory. Run first and after<br> any provider changes.</p> <p><strong>Q: Difference between terraform plan and apply?</strong><br> plan: shows what will change WITHOUT making changes.<br> apply: executes the plan after confirmation.<br> Always review plan before apply in production!</p> <p><strong>Q: What is Terraform state?</strong><br> terraform.tfstate maps HCL config to real resource IDs.<br> Source of truth for what Terraform manages.<br> Store remotely (S3 + DynamoDB) in teams.</p> <p><strong>Q: What are Terraform providers?</strong><br> Plugins that interface with cloud APIs.<br> Examples: hashicorp/aws, hashicorp/azurerm,<br> hashicorp/kubernetes. Declared in required_providers.</p> <h2> Intermediate Questions </h2> <p><strong>Q: count vs for_each — which to prefer?</strong><br> for_each: creates resources with stable string keys.<br> Removing one key only destroys that resource.<br> count: indexed numerically, removing middle item<br> causes destroy+recreate cascade.<br> Always prefer for_each!</p> <p><strong>Q: How do you handle secrets in Terraform?</strong><br> Never hardcode in .tf files (goes into state!).<br> Use: environment variables (TF_VAR_password),<br> AWS Secrets Manager data source,<br> HashiCorp Vault provider,<br> OIDC for passwordless cloud auth in CI/CD.</p> <p><strong>Q: What is remote state and why use it?</strong><br> Stores tfstate in S3/Terraform Cloud instead of locally.<br> Benefits: team sharing, DynamoDB locking prevents<br> concurrent applies, versioned, encrypted, backed up.</p> <p><strong>Q: What are Terraform modules?</strong><br> Reusable collection of resources with defined inputs<br> and outputs. Call with module block, access outputs<br> via module.name.output_name.</p> <p><strong>Q: How do you import existing resources?</strong><br> terraform import resource_type.name resource_id<br> Brings manually created resources under Terraform<br> management without recreating them.</p> <h2> Advanced Questions </h2> <p><strong>Q: How do you implement Terraform in CI/CD?</strong><br> PR: terraform fmt --check, validate, plan (post as comment)<br> Merge: terraform apply saved plan<br> Use OIDC for authentication — no stored AWS keys!<br> Tools: Atlantis, Terraform Cloud, GitHub Actions.</p> <p><strong>Q: What is infrastructure drift?</strong><br> Real infrastructure deviates from Terraform state<br> due to manual console changes.<br> Detection: terraform plan shows drift.<br> Prevention: no manual changes, scheduled plan in CI.</p> <p><strong>Q: How do you rollback in Terraform?</strong><br> No native rollback command. Options:</p> <ol> <li>Git revert .tf files, run apply</li> <li>Restore previous state from S3 versioning</li> <li>terraform destroy -target specific resource</li> </ol> <p><strong>Q: What is Terraform Sentinel?</strong><br> Policy-as-code framework in TF Cloud/Enterprise.<br> Enforces compliance before apply runs.<br> Use cases: require tags, cost limits, security rules.</p> <p>...and 26 more questions with answers 👇</p> <p>🔗 Full Q&amp;A + PDF Download: <br> <a href="https://devopsrise.vercel.app/qa" rel="noopener noreferrer">devopsrise.vercel.app/qa</a></p> <h2> Quick Reference </h2> <div class="table-wrapper-paragraph"><table> <thead> <tr> <th>Command</th> <th>Purpose</th> </tr> </thead> <tbody> <tr> <td>terraform init</td> <td>Initialize providers</td> </tr> <tr> <td>terraform plan</td> <td>Preview changes</td> </tr> <tr> <td>terraform apply</td> <td>Apply changes</td> </tr> <tr> <td>terraform destroy</td> <td>Destroy resources</td> </tr> <tr> <td>terraform state list</td> <td>List resources</td> </tr> <tr> <td>terraform import</td> <td>Import existing</td> </tr> <tr> <td>terraform fmt</td> <td>Format code</td> </tr> <tr> <td>terraform validate</td> <td>Validate config</td> </tr> </tbody> </table></div> <h1> devops #terraform #aws #iac </h1> terraform devops aws opensource DevOps Rise Fri, 10 Jul 2026 08:54:17 +0000 https://dev.to/devopsrise_0607/how-to-become-a-devops-engineer-in-2026-complete-roadmap-for-beginners-1f4d https://dev.to/devopsrise_0607/how-to-become-a-devops-engineer-in-2026-complete-roadmap-for-beginners-1f4d <h1> How to Become a DevOps Engineer in 2026 </h1> <p>Many people ask me — where do I start with DevOps?<br> Here's the exact structured path.</p> <p>I built a free platform with everything you need:<br> 🔗 <a href="https://devopsrise.vercel.app" rel="noopener noreferrer">devopsrise.vercel.app</a></p> <h2> Phase 1 — Linux Fundamentals (2 weeks) </h2> <p>Foundation of everything in DevOps.</p> <ul> <li>File system, permissions, processes</li> <li>Bash scripting basics</li> <li>SSH, networking commands</li> <li>systemd, cron jobs</li> </ul> <p><strong>Key commands to master:</strong></p> <ul> <li> <code>ls -la</code>, <code>chmod</code>, <code>chown</code>, <code>find</code> </li> <li> <code>ps aux</code>, <code>top</code>, <code>kill</code> </li> <li> <code>grep</code>, <code>awk</code>, <code>sed</code>, <code>tail -f</code> </li> </ul> <h2> Phase 2 — Git &amp; Version Control (1 week) </h2> <ul> <li>Branching, merging, rebasing</li> <li>GitHub workflow, Pull Requests</li> <li>Git hooks, conventional commits</li> <li>Trunk-based development</li> </ul> <h2> Phase 3 — Cloud/AWS (3 weeks) </h2> <ul> <li>EC2, S3, IAM, VPC</li> <li>RDS, Lambda, CloudWatch</li> <li>Auto Scaling, Load Balancer</li> <li>AWS CLI automation</li> </ul> <h2> Phase 4 — Docker (2 weeks) </h2> <ul> <li>Dockerfile, docker-compose</li> <li>Networking, volumes</li> <li>Multi-stage builds</li> <li>Security best practices</li> </ul> <h2> Phase 5 — Kubernetes (3 weeks) </h2> <ul> <li>Pods, Deployments, Services</li> <li>HPA, RBAC, Helm</li> <li>Production best practices</li> <li>Debugging CrashLoopBackOff</li> </ul> <h2> Phase 6 — CI/CD (2 weeks) </h2> <ul> <li>GitHub Actions pipelines</li> <li>Jenkins Declarative Pipeline</li> <li>Build → Test → Deploy automation</li> <li>ArgoCD for GitOps</li> </ul> <h2> Phase 7 — Terraform (2 weeks) </h2> <ul> <li>Provision AWS infrastructure as code</li> <li>State management, modules</li> <li>CI/CD for Terraform</li> <li>Security scanning with tfsec</li> </ul> <h2> Phase 8 — Monitoring (2 weeks) </h2> <ul> <li>Prometheus + Grafana setup</li> <li>AlertManager, Loki for logs</li> <li>SLOs and error budgets</li> <li>Kubernetes monitoring</li> </ul> <h2> Total Timeline </h2> <p>~4 months with 2-3 hours daily practice.</p> <h2> Free Resources </h2> <p>I created a complete FREE platform with:</p> <ul> <li>✅ 535+ Real Interview Questions (all 8 topics)</li> <li>✅ 122-Day day-by-day learning plan PDF</li> <li>✅ Commands Cheatsheet (click to copy)</li> <li>✅ Mock Interview Mode with timer</li> <li>✅ Free PDF downloads</li> </ul> <p>🔗 <strong><a href="https://devopsrise.vercel.app" rel="noopener noreferrer">devopsrise.vercel.app</a></strong></p> <p>No login.
