|---|---|
| DevOps Fundamentals | DevOps lifecycle, Agile vs DevOps, Cloud integration |
| Linux for DevOps | Commands, SSH, file permissions, network tools |
| Source Code Management | Git, GitHub, GitLab, Bitbucket workflows |
| CI/CD | Jenkins, pipelines, automation of tests & deployments |
| Scripting | YAML, Bash, Python basics for automation |
| Cloud Platforms | AWS, Azure, GCP tutorials and services |
| Docker | Containers, Dockerfiles, Compose, volumes |
| Kubernetes | Pods, services, deployments, ConfigMaps, Secrets |
| Infrastructure as Code (IaC) | Terraform, Ansible, CloudFormation, Chef |
Tips for Freshers
- Begin with strong fundamentals—don’t skip Linux basics
- Start scripting early with Bash and Python
- Build small projects to test your learning
